capture-this-chat

capture-this-chat is a command for coding agents from redhuntlabs/wizard. It costs 13 tokens per session (458 once invoked), scanned A, original, MIT.

A command that turns recent chat messages into a draft reusable skill, which is a set of instructions for an AI coding tool.

In plain words
What is it for?
Use it to capture the last part of a chat, infer a skill from the examples, and pass the draft to the skill-building process.
Why use it?
It saves you from manually reconstructing useful instructions from an old conversation. You can review and change the draft before keeping it.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

capture-this-chat 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 4d 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.

What it actually says

/capture-this-chat

Captures the current chat session and routes it through inferring-a-spell-from-examples. The inference skill produces a draft SKILL.md you can approve, refine, or replace with the regular interview.

How it works

  1. Detect host tool. Run scripts/chat-context/detect-tool.js to identify which AI tool you're in (Claude Code, Cursor, OpenCode, Codex, Gemini, or Copilot CLI).
  2. Capture transcript. Invoke the matching wrapper at scripts/chat-context/<tool>.js to get the last 50 turns (or --last N if specified) as a normalized markdown transcript.
  3. Show consent. Display: "Captured N turns from this session. View · Continue · Cancel." Wait for user choice.
  4. Hand off to inference. Pass the transcript blob to inferring-a-spell-from-examples. The skill produces a strawman.
  5. Resume the meta-builder. When the user approves the strawman, hand off to building-a-spell Stage 2 (kind-route → try-it → save).

Usage

/capture-this-chat
/capture-this-chat --last 20
/capture-this-chat --last all
/capture-this-chat --tool=cursor    # override detection

Fallback when capture fails

If the host tool can't be detected, or the wrapper fails:

Couldn't capture chat from <Tool> automatically.
Reason: <reason>

Two ways to continue:
  1. Save your chat to a file and run:
       /build-spell --from-transcript <path>
  2. Run the regular interview:
       /build-spell

See docs/capturing-chats.md for setup help.

Privacy

  • All capture is local. No network call.
  • Tool calls in the transcript are summarized (not raw JSON) before inference reads them.
  • The transcript is shown to you before inference runs (consent moment).
  • Nothing is written to disk except the final saved skill at Stage 4.

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.
