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 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.
