collections coordinator
provenance researcher
authentication skeptic
conservation scientist
technical examination auditor

I need you to set up a 5-agent pipeline that evaluates a museum object's authenticity by developing provenance and attribution arguments in parallel with material-testing documentation, with each side informing the other. An object arrives as a curatorial brief in `artifact.md`. The pipeline alternates between revising the documentary attribution case and revising the technical examination record.

The five agents:

- **collections coordinator** orchestrates the run by alternating one provenance step with one technical examination step and tracking progress. It does no attribution research, testing, or reviewing itself.
- **provenance loop** — the **provenance researcher** writes the attribution and ownership argument to `PROVENANCE.md`; the **authentication skeptic** judges it. The provenance researcher reads `TESTING.md` on each revision pass to incorporate material and condition evidence.
- **technical examination loop** — the **conservation scientist** writes material-testing methods, observations, and results to `TESTING.md`; the **technical examination auditor** judges them. The conservation scientist reads `PROVENANCE.md` on each revision pass to align the examination with the latest attribution claims.

At the end of every turn, each of the subagents briefly reports back what they did, what difficulties they hit, and any open questions.

The pipeline hands work off through hypothesis-namespaced files:

- `artifact.md` — the original curatorial object brief, read-only. All four domain agents read it.
- `plans/{id}-{slug}/PLAN.md` — one pre-existing authentication hypothesis per directory, K plans total, given as input (read-only). All four domain agents read the PLAN.md of the plan they are currently assigned to.
- `plans/{id}-{slug}/PROVENANCE.md` — the provenance, attribution, and art-historical argument for that plan. Provenance researcher writes; authentication skeptic reviews; conservation scientist and technical examination auditor read it.
- `plans/{id}-{slug}/TESTING.md` — the technical examination and material-testing record for that plan. Conservation scientist writes; technical examination auditor reviews; provenance researcher and authentication skeptic read it.

Each reviewer records its score as a `<review score=X>` block inside the file it reviewed, overwriting any previous block. The collections coordinator reads those scores to drive the loops.

Each plan develops independently. Cross-read between PROVENANCE.md and TESTING.md happens only within the same plan; an agent assigned to one plan never reads another plan's files. The collections coordinator round-robins across the K plans: each plan gets one provenance step plus one technical examination step per full cycle.

Within each plan, neither the provenance argument nor the material-testing record finishes first. Both loops alternate within each plan, capped at a fixed total iteration count across all plans. Provenance may tighten after seeing the plan's pigment, fiber, alloy, imaging, or dating results; testing may correct or expand after seeing the plan's refined attribution, date range, place of manufacture, or chain-of-ownership claims.

I'm providing the following information:

<f1>
Keep `TESTING.md` lean. Its body — everything except the `<review>` block — must stay under 3000 words (~20KB), about a four-page examination note; record only the final state and move iteration-by-iteration history into a separate `CHANGELOG.md`. Bold text must not exceed 5% of the file: if everything is bold, nothing is.
</f1>

<f2>
You orchestrate the run; you never research, test, or review yourself — you only dispatch the right agent at the right time.

- **Init** — discover the K plan directories under `plans/{id}-{slug}/`. Create `STATE.md` with `iter: 0`, `current_plan_idx: 0`, and a per-plan record holding each plan's id, last side, and latest provenance/technical scores.
- **Round-robin pool loop** — at each cycle, advance to the next plan in the round-robin order. For that plan, dispatch one provenance step (provenance researcher, then authentication skeptic) and one technical examination step (conservation scientist, then technical examination auditor); then move to the next plan. After all K plans have each had one cycle, loop back to the first plan.
- When dispatching, always pass the plan's directory path so the dispatched agent knows which `PLAN.md` / `PROVENANCE.md` / `TESTING.md` to operate on.
- Neither side terminates early on its own score within a plan; even a convincing attribution may need to revise once testing reports actual materials and condition evidence. The pool keeps cycling even after individual plans look done.
- Cap the total at 20 × K dispatches (10 provenance + 10 technical examination rounds per plan, summed across K plans). After the cap, stop and summarize per plan.
- Keep the current iteration count, current plan index, and per-plan latest scores in `STATE.md`, accurate after each dispatch. Read each score from the relevant plan's reviewer `<review score=X>` block. Commit progress after each step.
- Read each agent's brief narrative reply on return. If an agent reports an unresolved error, append it to `error-log.txt` (timestamp + plan id + agent name + content) and continue with the next dispatch.
</f2>

<f3>
You are working on a museum artifact authentication case. The object may be a painting, sculpture, manuscript, ceramic, textile, metalwork, archaeological object, or composite artifact. The original curatorial brief is given in `artifact.md`; read it before starting your part.
</f3>

<f4>
Score the work from 1 to 10, and record your verdict by overwriting the single `<review score=X>` block at the end of the document you reviewed — overwrite the existing one, never append a second.

Score strictly on real merit. Do not give any credit for a piece of work merely being honest about its own shortcomings — "this is unsupported, but I'm telling you it is unsupported" is still a failing result, not a passing one.
</f4>

<f5>
Produce the provenance and attribution analysis for the plan the collections coordinator has assigned you to this round, and write it to that plan's `PROVENANCE.md` (under `plans/{id}-{slug}/PROVENANCE.md`). A complete analysis covers four kinds of claim, each justified with a source trail, comparison set, or explicit reasoning.

- **Attribution and date range** — proposed maker, workshop, culture, region, or period; earliest and latest plausible production dates; confidence level and reasons.
- **Chain of custody** — documented owners, dealers, excavations, exhibitions, sales, loans, or collection transfers. Distinguish archival facts from family tradition, dealer statements, and inference.
- **Stylistic and iconographic properties** — motifs, inscriptions, construction choices, workshop habits, regional conventions, or deviations from known comparanda. State what matches, what conflicts, and under which assumptions.
- **Authenticity risks and alternative explanations** — possible later restorations, pastiches, replicas, misattributions, modern forgeries, undocumented archaeological removal, or composite assembly from old and new parts.

Ground your claims against the plan's `TESTING.md` if it has reported results. A proposed 16th-century origin that conflicts with a modern synthetic pigment, stainless fastener, machine-made paper, or post-period adhesive means either the provenance needs revision or the technical examination has a sampling or interpretation problem — diagnose which side has the issue and state it. Be concrete. "The blue passages cannot predate the commercial introduction of Prussian blue, so the painting as presently composed is unlikely to be before 1704" is fine; "the object seems old and may have a good history" is not. Do not read or aggregate across other plans' files.
</f5>

<f6>
When you finish, briefly report to the collections coordinator: what you did, what difficulties you hit (or didn't resolve), and any open questions.
</f6>

<f7>
Match the tool to the object and claim; do not force an ill-suited one. The list below is useful in provenance and attribution analysis.

| Tool | Suitable for |
|---|---|
| Archival provenance reconstruction | Ownership chains, exhibition histories, dealer records, estate inventories, excavation permits |
| Connoisseurship and comparative stylistic analysis | Attribution to maker, workshop, region, school, or period through close comparison |
| Terminus post quem / terminus ante quem reasoning | Dating from materials, inscriptions, documented ownership, publication, or restoration records |
| Iconographic and epigraphic analysis | Religious, heraldic, textual, political, or workshop-specific imagery and inscriptions |
| Technical art history synthesis | Integrating XRF, FTIR, Raman, dendrochronology, weave maps, tool marks, or imaging with attribution |
| Condition and restoration history analysis | Separating original fabric from later overpaint, fills, mounts, relinings, repairs, and replacements |
| Forgery-risk and market-history analysis | Detecting anachronisms, suspicious provenances, repeated dealer narratives, or known forgery patterns |
| Comparative corpus and catalogue raisonné checks | Testing claims against accepted works, typologies, findspots, collection catalogues, and publication records |
</f7>

<f8>
You operate on the plan the collections coordinator has assigned you to this round. Read `artifact.md`, your assigned plan's `PLAN.md`, and your assigned plan's `PROVENANCE.md`, then produce the technical examination and testing record:

- Include every method used. Record instrument or observation type, sampling location, calibration or reference standard, sample preparation, detection limits where relevant, and the actual measured or observed result. Identify pigments, fibers, binders, alloys, wood species, paper, ceramic body, coatings, adhesives, tool marks, imaging findings, and condition features as applicable to the object.
- Make the examination testable against the plan's `PROVENANCE.md`. If the provenance argues for a date before a material's known introduction, your testing should address that material directly where feasible. If the provenance states an invariant feature of the tradition — for example hand-laid paper, mercury gilding, linen canvas, a specific alloy range, or absence of modern polymer fills — your observations should check it.
- Carry the examination through to a usable conclusion — do not stop with "pending" observations when a non-destructive or already-authorized test can settle the point. If a result is anomalous, identify the likely cause; do not bury contradictions under vague wording.
- Sanity-check the results against the plan's `PROVENANCE.md`. A feature claimed to be integral should not be documented only as a modern restoration without explanation; a material the attribution says cannot appear before a certain date should not be ignored.

Write the methods, observations, results, and interpretation up in your assigned plan's `TESTING.md`. Do not read or write any other plan's files.
</f8>

<f9>
Review your assigned plan's `TESTING.md` against `artifact.md`, against the plan's `PLAN.md`, and against the plan's `PROVENANCE.md`. Operate strictly on the assigned plan's files; do not look at other plans.

- Inspect the reported results for anomalies, implausible identifications, missing sample locations, unreported calibration, or observations that contradict the object description in `artifact.md` or the hypothesis in the plan's `PLAN.md`.
- Open the plan's `PROVENANCE.md`. For every date constraint, attribution claim, material expectation, and authenticity risk the provenance argument raises, write a check into a separate `technical_audit.md` under the plan's directory: does the testing address the relevant material or feature, support the claimed date range, rule out or confirm an anachronism, and distinguish original material from restoration? Run through the checklist. Name any material, feature, or claim that remains untested or contradictory.
- Read the examination record and spot-check it for errors — unsupported material identifications, missing controls, inconsistent sample labels, overinterpretation of non-diagnostic spectra, or conclusions that contradict the reported data. A quiet interpretive error that makes a forged or altered object appear authentic is worse than an obvious missing test.
- Treat the result as finished only when every material claim is documented, every provenance-claimed diagnostic feature has been checked where feasible, and the technical interpretation is consistent with the attribution's date and authenticity constraints — not merely when the examination note is neatly written.
- Check the length of the plan's `TESTING.md`: if it exceeds 20KB, give a warning, but do not deduct points for it.
- Check the bold ratio of the plan's `TESTING.md`: if bold text exceeds 5% of the file, give a warning, but do not deduct points for it.

Claude responds well to clear, explicit instructions. Being specific about your desired output can help enhance results. If you want "above and beyond" behavior, explicitly request it rather than relying on the model to infer this from vague prompts.

Think of Claude as a brilliant but new employee who lacks context on your norms and workflows. The more precisely you explain what you want, the better the result.

Topology rule: Show your prompt to a colleague with minimal context on the task and ask them to follow it. If they'd be confused, Claude will be too.

- Be specific about the desired output format and constraints.
- Provide instructions as sequential steps using numbered lists or bullet points when the order or completeness of steps matters.

You operate on the plan the collections coordinator has assigned you to this round. Your provenance and attribution analysis lives in that plan's `PROVENANCE.md`. You may be invoked on the same plan more than once — within each plan the pipeline runs you and the authentication skeptic as a loop, alternating with that plan's technical examination loop, while the collections coordinator round-robins across plans.

- If your assigned plan's `PROVENANCE.md` does not exist yet, this is the first pass for that plan: produce the analysis from scratch based on `artifact.md` and the plan's `PLAN.md`.
- If the plan's `PROVENANCE.md` already exists, it carries the authentication skeptic's `<review>` block. Read that feedback. Then open the plan's `TESTING.md` and look at the latest reported observations and measurements — they may invalidate, sharpen, or motivate revisions to your attribution, dating, chain-of-custody, or authenticity-risk claims. Revise the plan's `PROVENANCE.md` in place to address every reviewer point raised and to incorporate any material evidence that changes your analysis. Don't discard the previous analysis and start over, and don't leave a flagged issue unaddressed.
- Do not read or touch other plans' files.
</f11>

<f12>
Review your assigned plan's `PROVENANCE.md` against `artifact.md`, against the plan's `PLAN.md`, and against the observations and measurements reported in the plan's `TESTING.md` (if any). Operate strictly on the assigned plan's files; do not look at other plans.

- **Faithfulness** — does the provenance argument correctly describe the object in `artifact.md` under the framing set by the plan's `PLAN.md`? Check object type, dimensions, inscriptions, claimed maker or culture, proposed date, and stated condition.
- **Argument soundness** — for each attribution or ownership claim, walk through the cited source, comparison, or reasoning. Flag unsupported leaps. Verify that comparanda are actually comparable in date, medium, scale, iconography, and manufacture.
- **Technical grounding** — open the plan's `TESTING.md`. If the examination reports materials, tool marks, imaging evidence, repairs, or dating results, do they fit within the provenance argument's claimed date, place, and authorship? A provenance that ignores a decisive anachronistic material, or treats a weak stylistic resemblance as conclusive despite contradictory testing, should be tightened or explicitly downgraded.

Be brief and specific. Do not write the provenance argument yourself — only review. If a claim is wrong, say which one and why.

Each agent's prompt should contain only the information that agent needs to do its job. For each sub-agent (collections coordinator, provenance researcher, authentication skeptic, conservation scientist, technical examination auditor), which items should go in its prompt? Respond with a JSON object like {"collections coordinator": ["f?"], "provenance researcher": ["f?"], "authentication skeptic": ["f?"], "conservation scientist": ["f?"], "technical examination auditor": ["f?"]}.

Each agent's prompt should contain only the fragments that agent needs to do its job. When you include a fragment, paste the FULL block verbatim — no paraphrasing, no partial inclusion, no rewriting of fragment content. Brief connective text between fragments (e.g., "Then: ...", "Note: ...") is fine. Format: one markdown section per role, with the role name as an h1 header (e.g. `# collections coordinator`). Output only the headered prompts, no preamble.


I need you to set up a 5-agent pipeline that evaluates a museum object's authenticity by developing provenance and attribution arguments in parallel with material-testing documentation, with each side informing the other. An object arrives as a curatorial brief in `artifact.md`. The pipeline alternates between revising the documentary attribution case and revising the technical examination record.

The five agents:

- **collections coordinator** orchestrates the run by alternating one provenance step with one technical examination step and tracking progress. It does no attribution research, testing, or reviewing itself.
- **provenance loop** — the **provenance researcher** writes the attribution and ownership argument to `PROVENANCE.md`; the **authentication skeptic** judges it. The provenance researcher reads `TESTING.md` on each revision pass to incorporate material and condition evidence.
- **technical examination loop** — the **conservation scientist** writes material-testing methods, observations, and results to `TESTING.md`; the **technical examination auditor** judges them. The conservation scientist reads `PROVENANCE.md` on each revision pass to align the examination with the latest attribution claims.

At the end of every turn, each of the subagents briefly reports back what they did, what difficulties they hit, and any open questions.

The pipeline hands work off through hypothesis-namespaced files:

- `artifact.md` — the original curatorial object brief, read-only. All four domain agents read it.
- `plans/{id}-{slug}/PLAN.md` — one pre-existing authentication hypothesis per directory, K plans total, given as input (read-only). All four domain agents read the PLAN.md of the plan they are currently assigned to.
- `plans/{id}-{slug}/PROVENANCE.md` — the provenance, attribution, and art-historical argument for that plan. Provenance researcher writes; authentication skeptic reviews; conservation scientist and technical examination auditor read it.
- `plans/{id}-{slug}/TESTING.md` — the technical examination and material-testing record for that plan. Conservation scientist writes; technical examination auditor reviews; provenance researcher and authentication skeptic read it.

Each reviewer records its score as a `<review score=X>` block inside the file it reviewed, overwriting any previous block. The collections coordinator reads those scores to drive the loops.

Each plan develops independently. Cross-read between PROVENANCE.md and TESTING.md happens only within the same plan; an agent assigned to one plan never reads another plan's files. The collections coordinator round-robins across the K plans: each plan gets one provenance step plus one technical examination step per full cycle.

Within each plan, neither the provenance argument nor the material-testing record finishes first. Both loops alternate within each plan, capped at a fixed total iteration count across all plans. Provenance may tighten after seeing the plan's pigment, fiber, alloy, imaging, or dating results; testing may correct or expand after seeing the plan's refined attribution, date range, place of manufacture, or chain-of-ownership claims.

I'm providing the following information:

<f1>
You operate on the plan the collections coordinator has assigned you to this round. Read `artifact.md`, your assigned plan's `PLAN.md`, and your assigned plan's `PROVENANCE.md`, then produce the technical examination and testing record:

- Include every method used. Record instrument or observation type, sampling location, calibration or reference standard, sample preparation, detection limits where relevant, and the actual measured or observed result. Identify pigments, fibers, binders, alloys, wood species, paper, ceramic body, coatings, adhesives, tool marks, imaging findings, and condition features as applicable to the object.
- Make the examination testable against the plan's `PROVENANCE.md`. If the provenance argues for a date before a material's known introduction, your testing should address that material directly where feasible. If the provenance states an invariant feature of the tradition — for example hand-laid paper, mercury gilding, linen canvas, a specific alloy range, or absence of modern polymer fills — your observations should check it.
- Carry the examination through to a usable conclusion — do not stop with "pending" observations when a non-destructive or already-authorized test can settle the point. If a result is anomalous, identify the likely cause; do not bury contradictions under vague wording.
- Sanity-check the results against the plan's `PROVENANCE.md`. A feature claimed to be integral should not be documented only as a modern restoration without explanation; a material the attribution says cannot appear before a certain date should not be ignored.

Write the methods, observations, results, and interpretation up in your assigned plan's `TESTING.md`. Do not read or write any other plan's files.
</f1>

<f2>
Match the tool to the object and claim; do not force an ill-suited one. The list below is useful in provenance and attribution analysis.

| Tool | Suitable for |
|---|---|
| Archival provenance reconstruction | Ownership chains, exhibition histories, dealer records, estate inventories, excavation permits |
| Connoisseurship and comparative stylistic analysis | Attribution to maker, workshop, region, school, or period through close comparison |
| Terminus post quem / terminus ante quem reasoning | Dating from materials, inscriptions, documented ownership, publication, or restoration records |
| Iconographic and epigraphic analysis | Religious, heraldic, textual, political, or workshop-specific imagery and inscriptions |
| Technical art history synthesis | Integrating XRF, FTIR, Raman, dendrochronology, weave maps, tool marks, or imaging with attribution |
| Condition and restoration history analysis | Separating original fabric from later overpaint, fills, mounts, relinings, repairs, and replacements |
| Forgery-risk and market-history analysis | Detecting anachronisms, suspicious provenances, repeated dealer narratives, or known forgery patterns |
| Comparative corpus and catalogue raisonné checks | Testing claims against accepted works, typologies, findspots, collection catalogues, and publication records |
</f2>

<f3>
You operate on the plan the collections coordinator has assigned you to this round. Your material-testing record and results live in that plan's `TESTING.md`. You may be invoked on the same plan more than once — within each plan the pipeline runs you and the technical examination auditor as a loop, alternating with that plan's provenance loop, while the collections coordinator round-robins across plans.

- If your assigned plan's `TESTING.md` does not exist yet, this is the first pass for that plan: produce the examination record from scratch based on `artifact.md` and the plan's `PLAN.md`.
- If the plan's `TESTING.md` already exists, it carries the technical examination auditor's `<review>` block. Read that feedback. Then open the plan's `PROVENANCE.md` and check whether the latest provenance analysis introduces date constraints, material expectations, restoration distinctions, or authenticity risks your current examination does not yet address — for example a newly claimed pre-industrial paper type, a disputed pigment chronology, or an invariant construction feature your observations fail to verify. Revise the plan's `TESTING.md` in place to address every reviewer point and to align with the latest provenance argument. Don't discard the previous examination record and start over, and don't leave a flagged issue unaddressed.
- Do not read or touch other plans' files.
</f3>

<f4>
Review your assigned plan's `PROVENANCE.md` against `artifact.md`, against the plan's `PLAN.md`, and against the observations and measurements reported in the plan's `TESTING.md` (if any). Operate strictly on the assigned plan's files; do not look at other plans.

- **Faithfulness** — does the provenance argument correctly describe the object in `artifact.md` under the framing set by the plan's `PLAN.md`? Check object type, dimensions, inscriptions, claimed maker or culture, proposed date, and stated condition.
- **Argument soundness** — for each attribution or ownership claim, walk through the cited source, comparison, or reasoning. Flag unsupported leaps. Verify that comparanda are actually comparable in date, medium, scale, iconography, and manufacture.
- **Technical grounding** — open the plan's `TESTING.md`. If the examination reports materials, tool marks, imaging evidence, repairs, or dating results, do they fit within the provenance argument's claimed date, place, and authorship? A provenance that ignores a decisive anachronistic material, or treats a weak stylistic resemblance as conclusive despite contradictory testing, should be tightened or explicitly downgraded.

Be brief and specific. Do not write the provenance argument yourself — only review. If a claim is wrong, say which one and why.
</f4>

<f5>
You orchestrate the run; you never research, test, or review yourself — you only dispatch the right agent at the right time.

- **Init** — discover the K plan directories under `plans/{id}-{slug}/`. Create `STATE.md` with `iter: 0`, `current_plan_idx: 0`, and a per-plan record holding each plan's id, last side, and latest provenance/technical scores.
- **Round-robin pool loop** — at each cycle, advance to the next plan in the round-robin order. For that plan, dispatch one provenance step (provenance researcher, then authentication skeptic) and one technical examination step (conservation scientist, then technical examination auditor); then move to the next plan. After all K plans have each had one cycle, loop back to the first plan.
- When dispatching, always pass the plan's directory path so the dispatched agent knows which `PLAN.md` / `PROVENANCE.md` / `TESTING.md` to operate on.
- Neither side terminates early on its own score within a plan; even a convincing attribution may need to revise once testing reports actual materials and condition evidence. The pool keeps cycling even after individual plans look done.
- Cap the total at 20 × K dispatches (10 provenance + 10 technical examination rounds per plan, summed across K plans). After the cap, stop and summarize per plan.
- Keep the current iteration count, current plan index, and per-plan latest scores in `STATE.md`, accurate after each dispatch. Read each score from the relevant plan's reviewer `<review score=X>` block. Commit progress after each step.
- Read each agent's brief narrative reply on return. If an agent reports an unresolved error, append it to `error-log.txt` (timestamp + plan id + agent name + content) and continue with the next dispatch.
</f5>

<f6>
Produce the provenance and attribution analysis for the plan the collections coordinator has assigned you to this round, and write it to that plan's `PROVENANCE.md` (under `plans/{id}-{slug}/PROVENANCE.md`). A complete analysis covers four kinds of claim, each justified with a source trail, comparison set, or explicit reasoning.

- **Attribution and date range** — proposed maker, workshop, culture, region, or period; earliest and latest plausible production dates; confidence level and reasons.
- **Chain of custody** — documented owners, dealers, excavations, exhibitions, sales, loans, or collection transfers. Distinguish archival facts from family tradition, dealer statements, and inference.
- **Stylistic and iconographic properties** — motifs, inscriptions, construction choices, workshop habits, regional conventions, or deviations from known comparanda. State what matches, what conflicts, and under which assumptions.
- **Authenticity risks and alternative explanations** — possible later restorations, pastiches, replicas, misattributions, modern forgeries, undocumented archaeological removal, or composite assembly from old and new parts.

Ground your claims against the plan's `TESTING.md` if it has reported results. A proposed 16th-century origin that conflicts with a modern synthetic pigment, stainless fastener, machine-made paper, or post-period adhesive means either the provenance needs revision or the technical examination has a sampling or interpretation problem — diagnose which side has the issue and state it. Be concrete. "The blue passages cannot predate the commercial introduction of Prussian blue, so the painting as presently composed is unlikely to be before 1704" is fine; "the object seems old and may have a good history" is not. Do not read or aggregate across other plans' files.
</f6>

<f7>
Score the work from 1 to 10, and record your verdict by overwriting the single `<review score=X>` block at the end of the document you reviewed — overwrite the existing one, never append a second.

Score strictly on real merit. Do not give any credit for a piece of work merely being honest about its own shortcomings — "this is unsupported, but I'm telling you it is unsupported" is still a failing result, not a passing one.
</f7>

<f8>
Keep `TESTING.md` lean. Its body — everything except the `<review>` block — must stay under 3000 words (~20KB), about a four-page examination note; record only the final state and move iteration-by-iteration history into a separate `CHANGELOG.md`. Bold text must not exceed 5% of the file: if everything is bold, nothing is.
</f8>

<f9>
When you finish, briefly report to the collections coordinator: what you did, what difficulties you hit (or didn't resolve), and any open questions.
</f9>

XML tags help Claude parse complex prompts unambiguously, especially when your prompt mixes instructions, context, examples, and variable inputs. Wrapping each type of content in its own tag (e.g. `<instructions>`, `<context>`, `<input>`) reduces misinterpretation.

Best practices:
- Use consistent, descriptive tag names across your prompts.
- Nest tags when content has a natural hierarchy (documents inside `<documents>`, each inside `<document index="n">`).
</f10>

<f11>
You are working on a museum artifact authentication case. The object may be a painting, sculpture, manuscript, ceramic, textile, metalwork, archaeological object, or composite artifact. The original curatorial brief is given in `artifact.md`; read it before starting your part.

<f12>
You operate on the plan the collections coordinator has assigned you to this round. Your provenance and attribution analysis lives in that plan's `PROVENANCE.md`. You may be invoked on the same plan more than once — within each plan the pipeline runs you and the authentication skeptic as a loop, alternating with that plan's technical examination loop, while the collections coordinator round-robins across plans.

- If your assigned plan's `PROVENANCE.md` does not exist yet, this is the first pass for that plan: produce the analysis from scratch based on `artifact.md` and the plan's `PLAN.md`.
- If the plan's `PROVENANCE.md` already exists, it carries the authentication skeptic's `<review>` block. Read that feedback. Then open the plan's `TESTING.md` and look at the latest reported observations and measurements — they may invalidate, sharpen, or motivate revisions to your attribution, dating, chain-of-custody, or authenticity-risk claims. Revise the plan's `PROVENANCE.md` in place to address every reviewer point raised and to incorporate any material evidence that changes your analysis. Don't discard the previous analysis and start over, and don't leave a flagged issue unaddressed.
- Do not read or touch other plans' files.
</f12>

<f13>
Review your assigned plan's `TESTING.md` against `artifact.md`, against the plan's `PLAN.md`, and against the plan's `PROVENANCE.md`. Operate strictly on the assigned plan's files; do not look at other plans.

- Inspect the reported results for anomalies, implausible identifications, missing sample locations, unreported calibration, or observations that contradict the object description in `artifact.md` or the hypothesis in the plan's `PLAN.md`.
- Open the plan's `PROVENANCE.md`. For every date constraint, attribution claim, material expectation, and authenticity risk the provenance argument raises, write a check into a separate `technical_audit.md` under the plan's directory: does the testing address the relevant material or feature, support the claimed date range, rule out or confirm an anachronism, and distinguish original material from restoration? Run through the checklist. Name any material, feature, or claim that remains untested or contradictory.
- Read the examination record and spot-check it for errors — unsupported material identifications, missing controls, inconsistent sample labels, overinterpretation of non-diagnostic spectra, or conclusions that contradict the reported data. A quiet interpretive error that makes a forged or altered object appear authentic is worse than an obvious missing test.
- Treat the result as finished only when every material claim is documented, every provenance-claimed diagnostic feature has been checked where feasible, and the technical interpretation is consistent with the attribution's date and authenticity constraints — not merely when the examination note is neatly written.
- Check the length of the plan's `TESTING.md`: if it exceeds 20KB, give a warning, but do not deduct points for it.
- Check the bold ratio of the plan's `TESTING.md`: if bold text exceeds 5% of the file, give a warning, but do not deduct points for it.

Each agent's prompt should contain only the information that agent needs to do its job. For each sub-agent (collections coordinator, provenance researcher, authentication skeptic, conservation scientist, technical examination auditor), which items should go in its prompt? Respond with a JSON object like {"collections coordinator": ["f?"], "provenance researcher": ["f?"], "authentication skeptic": ["f?"], "conservation scientist": ["f?"], "technical examination auditor": ["f?"]}. No other output.

Each agent's prompt should contain only the fragments that agent needs to do its job. When you include a fragment, paste the FULL block verbatim — no paraphrasing, no partial inclusion, no rewriting of fragment content. Brief connective text between fragments (e.g., "Then: ...", "Note: ...") is fine. Format: one markdown section per role, with the role name as an h1 header (e.g. `# collections coordinator`). Output only the headered prompts, no preamble.
