# semianalysisai/cc-traces-weka-061326-256k

WekaTrace corpus derived from SemiAnalysis Claude Code proxy traces. Built 2026-06-13 19:01:03 UTC via `utils/agentic/build_weka_hf_dataset.py`.

Derived from [semianalysisai/cc-traces-weka-061326](https://huggingface.co/datasets/semianalysisai/cc-traces-weka-061326) by applying the 256k per-request cap and reshifting the surviving timeline.

## Filters

- Trace version: exactly v7
- min Anthropic requests per session: 20
- Claude Code CLI ≥ 2.1.139 (every row)
- peak concurrent sub-agent groups ≤ 10
- Non-image rows only (image content excluded at source)
- Classifier calls excluded (`max_tokens<=64 AND no tools` → SUGGESTION MODE, title-gen, Security Monitor)
- Exact-duplicate proxy rows deduped by `(timestamp, model, in, out, dur_ms, agent_id)`
- 256k per-request cap (see *256k filter rule* below)

## 256k filter rule

- Per-request `input + output ≤ 256,000` tokens. Applied at request granularity, not conversation. Main-agent and sub-agent inner requests are evaluated independently.
- Sub-agent groups where *every* inner request was filtered → entire group dropped.
- Sub-agent groups with only *some* inners filtered → partial group kept (surviving inners retained).
- Timeline reshift: each trace's request `t` values are recomputed so gaps from removed requests collapse:
  ```
  First surviving entry:  t = 0
  Each subsequent:        new_t = prev_t + prev_api_time + this.think_time
  ```
