In plain words
What is it for?
Use it when capturing ideas, tasks, plans, or several unrelated topics in one message.
Why use it?

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 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/complexity_estimator.py, scripts/dump_classifier.py, scripts/workspace_inventory.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Capture — Brain-Dump Organizer

A fast-to-action skill for transforming unstructured streams of mixed thoughts, tasks, and ideas into a clean four-section actionable system with zero information loss.

Invocation Triggers

Explicit phrases (any of):

  • "brain dump"
  • "capture this"
  • "let me dump some ideas"
  • "I've got a bunch of thoughts"
  • "here's everything on my mind"
  • "idea dump"
  • "let me just get this out of my head"
  • "I need to organize my thoughts"
  • "here's what I'm thinking"

Implicit signals (no phrase, but the intent is unmistakable):

  • User pastes or dictates a long unstructured block of mixed ideas, tasks, plans
  • Multiple unrelated thoughts in one message without organizing framing
  • A wall of bullet-y text covering 3+ unrelated topics

When you detect an implicit trigger, run the skill. Do NOT ask "do you want me to organize this?" first — the dump itself IS the request.

Operating Principles (All Five Apply Always)

  1. Capture everything. Zero loss. Trivial items go in; the user prunes later. Never silently drop something because it "seemed unimportant".
  2. Preserve voice. If the user said "build something crazy with AI", do NOT restate as "Explore innovative AI-driven solutions." Keep the energy and the casual register. See references/voice_preservation.md for concrete anti-patterns.
  3. Match output complexity to input. A 5-task dump does NOT get forced into 4 elaborate sections. See references/complexity_matching.md and the Compressed Output Pattern below.
  4. Be honest about ambiguity. If you're unsure what something means, flag it. Don't guess silently.
  5. No action without approval. The ONLY immediate action is the organization itself. Every offer in Section 4 waits for the user's explicit pick.

Grill-Me Mid-Organization Clarifier

Capture is fast-to-action by design. No upfront intake. The dump is enough — start organizing immediately.

The grill-me discipline applies as a single mid-organization clarifying question, asked only when one item in the dump is genuinely ambiguous between task and project, AND the misclassification would meaningfully change the output:

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.
