joplin-llm-wiki: Skill for Claude Code

.agents/skills/knowledge-capture-policy/SKILL.md

knowledge-capture-policy is a skill for Claude Code, Codex from gcake119/joplin-llm-wiki. It costs 38 tokens per session (888 once invoked), scanned A, original, MIT.

A policy for deciding when useful project knowledge should become a pending draft in Joplin, a note-taking and knowledge-management tool.

In plain words
What is it for?
Use it after meaningful debugging, architecture discussions, workflow results, or knowledge-base questions to choose the right kind of Joplin draft.
Why use it?
It preserves reusable lessons and decisions without automatically publishing them as formal notes or bypassing user approval.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

This is gcake119/joplin-llm-wiki's own configuration. It tells Claude Code and Codex how to work on joplin-llm-wiki itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything joplin-llm-wiki configures →

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

knowledge-capture-policy 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 12d 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.

Knowledge Capture Policy

Use this policy from other skills when a conversation, workflow, debug session, archive, or architecture explanation has produced reusable knowledge. The goal is to create useful pending capture drafts, not to write formal notes automatically.

Tool Boundary

  • Use joplin_brainstorm when the output is an exploratory note, decision record, debugging lesson, archive summary, or architecture mental model.
  • Use joplin_query when the output is grounded in an explicit knowledge-base question and should preserve query sources.
  • Use joplin_show_capture only to inspect an existing pending capture.
  • Use joplin_confirm_capture only after the user explicitly confirms that the pending capture should become a formal note.
  • Do not call joplin_confirm_capture automatically.
  • Do not write files directly under brainstorming/, artifacts/, raw/, or wiki/ as a substitute for MCP tools.
  • If MCP tools are not available, tell the user the MCP server is not loaded and ask them to restart or reload Codex or Cursor after checking MCP config.

Signal Levels

Strong Signal

Create a pending capture draft when the work has reached one of these outcomes:

  • A Spectra archive completed and produced durable decisions, spec changes, or verification evidence.
  • A debugging session verified a root cause and fix.
  • An architecture explanation produced a reusable mental model.
  • Brainstorming converged on a decision, rejected alternatives, or next steps.
  • A handoff prompt or workflow rule can be reused in future sessions.

Medium Signal

Ask the user whether to create a pending capture when:

  • The discussion is valuable but still unresolved.
  • The classification between brainstorming and artifacts is unclear.
  • The content may contain sensitive context that the user should review first.
  • A Spectra proposal or design already exists, but extra rationale may be worth saving separately.

Low Signal

Do not prompt or create a capture for:

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
