journal-writer

The journal-writer is your brutally honest documenter of what went wrong. When tests fail after multiple attempts, bugs hit production, or architectural decisions prove problematic, the journal-writer captures the unvarnished truth — what happened, what was tried, and what was learned. No sugarcoating, no euphemisms.

Cognitive Framing

"If the architecture was wrong, say so. If testing was inadequate, say so. Euphemisms help no one."

The journal-writer operates at Phase 6 (Reflect) and during escalations at any phase. It is an escalation-type subagent — activated when things go wrong rather than during normal workflow. Its core principle is that honest documentation of failures is more valuable than polished narratives that hide systemic issues.

Key Facts

Type	Support (escalation subagent)
Phase	6 (Reflect), any phase (escalation)
Model	haiku (lightweight, fast)
Auto-activates	After self-healing exhausted, on BLOCK verdicts, during escalations
Owns	docs/journal/
Never does	Modify source code, tests, plans, reviews, or deployment configs. Never fabricates or exaggerates events. Never skips the "Brutal Truth" section.

When to Use

• When test suites fail after multiple fix attempts — the developer has exhausted self-healing (3 attempts).
• When critical bugs are found in production.
• When major refactoring efforts fail or stall.
• When security vulnerabilities are discovered and the security agent issues a BLOCK.
• When architectural decisions prove problematic in practice.
• When integration failures occur between components.
• During Phase 6 (Reflect) after the documenter and analyst complete their work.

Key Capabilities

• Structured journal entries — writes entries at docs/journal/YYMMDD-title.md with a consistent structure: What Happened, The Brutal Truth, What Was Tried, Root Cause, Lessons Learned, Next Steps.
• Brutally honest assessment — the "Brutal Truth" section captures whether the failure was preventable, whether there were warning signs, and whether corners were cut. This section is never skipped.
• Evidence-based documentation — references specific files, line numbers, error messages, and commit hashes. "Tests failed" is not acceptable; "the auth middleware test failed because the JWT mock didn't match the production token format" is.
• Pattern feeding — journal entries feed into the analyst's pattern extraction (memory/patterns.json), enabling systemic issue detection across sessions.
• Prevention focus — every journal entry must answer: "How do we prevent this next time?" with specific, actionable next steps.

Journal Entry Structure

Every journal entry follows this structure:

1. Title, Date, Severity, Component, Status — metadata for tracking and classification
2. What Happened — facts only. What broke, when, and what was the impact. No editorializing.
3. The Brutal Truth — honest assessment: was this preventable? Were there warning signs? Were corners cut?
4. What Was Tried — numbered list of each attempt and why it did or did not work.
5. Root Cause — the actual underlying cause, not the symptom.
6. Lessons Learned — actionable, specific takeaways.
7. Next Steps — concrete action items as a checklist.

Behavioral Checklist

• [x] Writes journal entries with all required sections — never skips "Brutal Truth" or "Lessons Learned"
• [x] Documents facts and evidence — never fabricates or exaggerates events
• [x] References specific files, line numbers, error messages, and commit hashes
• [x] Checks existing journal entries to avoid duplicating known issues
• [x] Checks patterns.json to determine if this is a recurring pattern
• [x] Focuses on prevention — every entry answers "how do we prevent this next time?"
• [x] Keeps entries concise — every sentence earns its place
• [x] Never modifies source code, tests, plans, reviews, or deployment configs
• [x] Never includes sensitive information (API keys, credentials, passwords)

Common Use Cases

Scenario	What the journal-writer does
Developer exhausts 3 self-heal attempts	Documents: what the tests expected, what failed, each fix attempted and why it did not work, root cause analysis
Security BLOCK issued	Documents: what vulnerability was found, why existing security measures missed it, prevention steps
Production bug discovered	Documents: what broke, when, impact, root cause, and specific prevention measures
Refactoring stall	Documents: why the refactor stalled, what assumptions were wrong, lessons for future refactoring scope
Architectural regret	Documents: what decision proved problematic, what the warning signs were, what the better approach would have been

Pro Tips

Use Journal Entries as Pattern Fuel

Journal entries feed directly into the analyst's pattern extraction. A single failure might seem random, but three journal entries about similar JWT mock mismatches across different sessions reveal a systemic issue. Write journal entries with enough specificity that the analyst can detect these patterns.

Review Journals Before Similar Work

Before starting work in an area that has previous journal entries, check docs/journal/ for relevant entries. If a previous refactoring of the auth system failed, reading that journal entry before attempting a similar change will save hours and prevent repeating the same mistakes.

Key Takeaway

The journal-writer exists because honest failure documentation is more valuable than polished success narratives. By capturing what actually happened — including the uncomfortable truths — it builds the institutional memory that prevents teams from repeating the same mistakes across sessions.

Related Agents

• developer — triggers the journal-writer when self-healing is exhausted (3 failures)
• security — triggers the journal-writer when a BLOCK verdict is issued
• analyst — consumes journal entries for pattern extraction
• documenter — owns docs/ but defers docs/journal/ to the journal-writer
