# semianalysisai/cc-traces-weka-062126-256k

WekaTrace corpus derived from SemiAnalysis Claude Code proxy traces. Built 2026-06-21 17:49:45 UTC via `utils/agentic/build_weka_hf_dataset.py`.

Derived from [semianalysisai/cc-traces-weka-062126](https://huggingface.co/datasets/semianalysisai/cc-traces-weka-062126) by applying the 256k per-request cap and preserving the surviving requests' relative timestamps.

## 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)`
- Dynamic-workflow-bug sessions excluded: Claude Code CLI < 2.1.174 emitted dynamic-workflow subagents without a subagent-label header, so they appear as many interleaved unlabeled trajectories in one session. Dropped when peak concurrent unlabeled multi-turn trajectories ≥ 3 (changelog 2.1.174).
- 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 preservation: surviving request `t` values keep their original relative offsets, including sub-agent overlap. If the first request was filtered, all surviving timestamps are shifted by one uniform offset so the earliest survivor starts at `t = 0`.
