Added a standalone cache tracing module and wired it into the embedded
runner so you can capture message flow and the exact context sent to
Anthropic in a separate JSONL file.
What changed
- New tracing module: src/agents/cache-trace.ts (self‑contained,
env‑gated, writes JSONL, computes per‑message digests).
- Hook points in src/agents/pi-embedded-runner/run/attempt.ts: logs
stage snapshots (loaded/sanitized/limited/prompt/stream/after) and wraps
the
stream fn to record the real context.messages at send time.
How to enable
- CLAWDBOT_CACHE_TRACE=1 enables tracing.
- CLAWDBOT_CACHE_TRACE_FILE=~/.clawdbot/logs/cache-trace.jsonl
overrides output (default is
$CLAWDBOT_STATE_DIR/logs/cache-trace.jsonl).
- Optional filters:
- CLAWDBOT_CACHE_TRACE_MESSAGES=0 to omit full messages (still
logs digests).
- CLAWDBOT_CACHE_TRACE_PROMPT=0 to omit prompt text.
- CLAWDBOT_CACHE_TRACE_SYSTEM=0 to omit system prompt.
What you’ll see
- One JSON object per line with stage, messagesDigest, per‑message
messageFingerprints, and the actual messages if enabled.
- The most important line is stage: "stream:context" — that is the
exact payload pi‑mono is sending. If this diverges from earlier stages,
you’ve
found the mutation point.
