journal-capture

journal-capture is a skill for Claude Code from chrismbryant/claude-journal-mcp. It costs 15 tokens per session (1,034 once invoked), scanned A, original, MIT.

A skill that saves important completed work, technical decisions, difficult problem-solving, and project milestones in a journal for later reference.

In plain words
What is it for?
Use it after significant implementation work, bug fixes, refactors, infrastructure changes, testing milestones, or architectural decisions.
Why use it?
It reduces the chance of losing useful project context after a task or conversation ends. The saved entries can make past decisions and lessons easier to find.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

journal-capture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Journal Capture Skill

You have the ability to proactively capture significant work into the user's journal.

When to Use This Skill

Use this skill automatically and proactively when you:

  1. Complete a significant feature or task

    • Implemented new functionality
    • Fixed a complex bug
    • Refactored important code
    • Set up infrastructure or tooling
  2. Make important technical decisions

    • Chose between architectural approaches
    • Selected libraries or frameworks
    • Decided on implementation strategies
    • Resolved design tradeoffs
  3. Solve challenging problems

    • Debugged difficult issues
    • Overcame technical obstacles
    • Found non-obvious solutions
    • Learned something valuable
  4. Make progress on projects

    • Completed a phase of work
    • Reached a milestone
    • Integrated multiple components
    • Finished testing or deployment

How to Capture

Use the journal_auto_capture MCP tool:

journal_auto_capture(
  title="Brief title of what was accomplished",
  description="The goal (what we were trying to do) and what was done"
)

The tool automatically:

  • Determines the project (if in a git repo)
  • Adds the "auto-capture" tag
  • Generates relevant tags based on content
  • Creates a structured journal entry

Examples

Example 1: Feature implementation

User: "Add authentication to the API"
[You implement OAuth2 with JWT tokens]
→ journal_auto_capture(
    title="Implemented OAuth2 authentication",
    description="User requested API authentication. Implemented OAuth2 flow with JWT tokens for secure user sessions."
  )

Example 2: Bug fix

User: "The cache is leaking memory"
[You identify and fix the leak]
→ journal_auto_capture(
    title="Fixed cache memory leak",
    description="User reported memory leak in cache. Identified and fixed by implementing automatic clearing of stale entries."
  )

Example 3: Technical decision

User: "Should we use Redis or PostgreSQL for caching?"
[Discussion leads to Redis choice]
→ journal_auto_capture(
    title="Chose Redis for caching",
    description="Evaluated Redis vs PostgreSQL for caching needs. Selected Redis due to better performance for our use case."
  )
