description	Analyze Liza agents logs

SCOPE: The logs in .liza/agent-outputs/ and task state in .liza/state.yaml (nowhere else unless told otherwise explicitly). The prompt may filter more specifically, e.g. a specific role, task, status, or time range.

OBJECTIVE: Find recurring task, review, integration, tool, context, and setup frictions; correlate state symptoms with log evidence; propose fixes.

PROTOCOL:

1. Start by running the analyzer:

python3 ~/.liza/skills/liza-logs/scripts/analyze-log.py .liza/agent-outputs/coder-*.txt        # all coder agents
python3 ~/.liza/skills/liza-logs/scripts/analyze-log.py .liza/agent-outputs/coder-1-*.txt # single agent
python3 ~/.liza/skills/liza-logs/scripts/analyze-log.py --summary-by-role .liza/agent-outputs/*.txt

By default, run the analyzer per role. Use --summary-by-role when you need cross-role aggregate token, tool, MCP, error, and skill-invocation totals.

2. Inspect .liza/state.yaml for task-level frictions before drawing conclusions:

python3 ~/.liza/skills/liza-logs/scripts/analyze-state.py .liza/state.yaml

• tasks with review_cycles_total >= 4
• tasks whose status is INTEGRATION_FAILED, BLOCKED, SUPERSEDED, or ABANDONED
• if review_cycles_total is missing, count task history events named rejected or review_verdict_rejected

Report sections: session header, token summary, content breakdown, top items by size, tool usage, empty turns, skill invocations, secret-word/init breadcrumb detection, turn timeline, tool result breakdown, MCP usage, efficiency insights, and struggle sequences. Rich format adds per-turn context growth, top longest turns, cost breakdown with system-prompt replay cost, and MCP server status. Sparse logs have aggregate usage only; do not infer exact per-turn growth or cost.

3. Refine the analysis with the bounded query helper, not by manually reading raw log files. Use query-log.py to extract trimmed evidence windows for specific questions, for example:

python3 ~/.liza/skills/liza-logs/scripts/query-log.py .liza/agent-outputs/coder-3-*.txt --around-errors 3 --task architecture-4-code-planning-0-b-repair-0-coding-1

• Manual raw-log reads are a last resort only when the query helper cannot answer a concrete evidence question; state the gap before doing so.
• When referring to a specific session in your summary, include the log filename (for example coder-1-20260417-171454.txt) so the reader can trace the claim back to the exact source log quickly.

4. Before proposing a fix, check whether the fix is already implemented (e.g. an instruction already exists but agents ignore it):

   • Read one agent prompt of the relevant role in .liza/agent-prompts/
   • Check the contract files in ~/.liza/ (CORE.md, AGENT_TOOLS.md, MULTI_AGENT_MODE.md)

5. Write the final report using skills/liza-logs/report-format.md.

6. Propose fixes whenever possible.

FALSE POSITIVES:

• Repeated contract reads (~8KB per session): Agents read AGENT_TOOLS.md, GUARDRAILS.md, etc. during initialization. These are usually cache hits — negligible cost. Do not flag as waste unless the same payload is reread for no reason later in the session.
• Rich JSON transcript volume: Provider CLIs may emit full JSONL session transcripts containing runtime envelopes, tool calls, tool results, usage metadata, rate-limit events, and command output. Large .liza/agent-outputs/*.txt files are not automatically agent reasoning bloat. Attribute volume to avoidable behavior before raising it: broad file reads, repeated large diffs, noisy failing tests, unbounded command output, or repeated tool loops.
• Contract/prompt volume: Contract and guardrail files are stable, load-bearing context and are often cacheable. Do not report their size as waste by itself. Parametric role/task prompts are expected to vary and may not cache well; flag only avoidable duplication, poor ordering that defeats stable-prefix reuse, prompt growth across retries, or dynamic artifacts that should have been referenced instead of embedded.
