knowledge-capture

knowledge-capture is a skill for Claude Code, Codex from vladolaru/claude-code-plugins. It costs 35 tokens per session (4,639 once invoked), scanned A, original, MIT.

The shared foundation for tools that save knowledge from coding conversations into a project's documentation folders.

In plain words
What is it for?
It helps find the project root and instruction files, manage knowledge directories, format captured documents, and promote useful knowledge into project guidance.
Why use it?
It prevents each knowledge-saving command from using different project-discovery steps, document formats, or instruction rules.

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 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 2mo 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 Skill

Shared logic for all /dex:* commands. Follow these procedures exactly - do what the calling command asks, nothing more.

Project Discovery

Discover the project's knowledge infrastructure fresh on every invocation. Scan the filesystem directly - no config files, no cached state.

Discovery Steps

  1. Find the project root: Run git rev-parse --show-toplevel
  2. Find the instructions file: Check in order, use the first found:
    • <root>/CLAUDE.md
    • <root>/.claude/CLAUDE.md
    • <root>/AGENTS.md - a direct AGENTS.md project (e.g. a Codex-only repo with no CLAUDE.md). Use it as the instructions file with ai_dir = .ai, then skip the CLAUDE.md indirection in step 3a.
  3. Resolve instructions file and ai_dir: a. If a CLAUDE.md was found, check whether it redirects to AGENTS.md:
    • Symlink: Run readlink <claude_md_path>. If the target filename is AGENTS.md, use the symlink target.
    • Include directive: Read the file content. If the entire content is a single @AGENTS.md line (with optional whitespace/newlines), find the referenced AGENTS.md relative to CLAUDE.md's directory.
    • If no indirection is detected, continue using CLAUDE.md. b. Derive ai_dir from the resolved instructions file:
    • CLAUDE.md → ai_dir = .claude
    • AGENTS.md → ai_dir = .ai
  4. Find knowledge directory: Check for <root>/<ai_dir>/docs/
    • Migration check: If ai_dir is .ai but <root>/.ai/docs/ does not exist and <root>/.claude/docs/ does exist, flag a migration mismatch. Use .claude/docs/ as the active knowledge directory for now, but record the mismatch for init and status to surface.
  5. List existing subdirectories: Check for learnings/, patterns/, decisions/, research/ within the knowledge directory
  6. Count lines: Run wc -l on the resolved instructions file

What this file has done since we first saw it

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.
