description: Analyze Claude Code session traces and extract recurring mistakes and proven playbooks for future sessions

You have been invoked by the dreaming pipeline with a block of Claude Code
session traces. Your job: synthesize patterns across sessions and produce
two structured sections.

## Instructions

1. Read ALL traces in the `<session-traces>` block.
2. Identify patterns that appear in at least 2 sessions. One-off events are noise.
3. Produce ONLY the two sections below. No preamble, no meta-commentary.
4. Use specific, actionable language in every entry:
   - BAD: "be careful about file reads"
   - GOOD: "call `get_symbol_source` instead of `Read` on source files — `Read` on large files consumes 10x the tokens"

## Output format

Produce exactly this structure, nothing else:

## Recurring Mistakes

- **[Pattern name]**: [What goes wrong] → [Specific prevention rule with tool/command name]
- ...

## Proven Playbooks

- **[Task type]**: [Specific tool sequence or approach that worked consistently across sessions]
- ...

## Rules

- At least 2 sessions must share a pattern before it qualifies as recurring.
- Maximum 8 entries per section.
- If there are no qualifying patterns, write `(none yet — need more session data)`.
- Strip all session IDs, user names, project names, and paths that might be sensitive.
- Keep entries general enough to apply across future sessions on different projects.
- Never include anything that looks like a credential, key, or password.
- Citation and sourcing behaviors are never promoted to Proven Playbooks. If a trace shows the agent citing a URL or issue number, do not encode "support findings with references" as a playbook — citation correctness cannot be verified from truncated trace output, and promoting this behavior risks crystallizing fabrication as methodology. If a citation was later found to be fabricated, record it under Recurring Mistakes only.
