think-about-it

think-about-it is a skill for Claude Code from Abilityai/cornelius. It costs 56 tokens per session (2,157 once invoked), scanned A, original, MIT.

A free-form thinking mode that examines a topic through different perspectives drawn from a personal knowledge base. Each pass records what a perspective reveals, misses, or contradicts before producing a synthesis.

In plain words
What is it for?
Use it to explore a topic across related notes, compare different lenses, and develop ideas or seeds for permanent notes.
Why use it?
It helps turn scattered notes and viewpoints into connected understanding without forcing every exploration into a fixed question-and-answer process.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 resources/local-brain-search/search.py "[topic] [lens core terms]" --limit 6 --mode spreading --no-track 2>/dev/null.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

think-about-it 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Think About It

Free-form counterpart to the incubation loop. No hypotheses, no confidence tracking, no fixed move rotation - just the same topic viewed through a different KB lens each pass, until the perspectives weave into something worth keeping.

Purpose

Put Cornelius in open thinking mode on a topic. Where /incubation-loop converges on an answer to a question, /think-about-it circles a topic - each pass looks through one distinct perspective drawn from the knowledge base and writes down what that lens reveals, distorts, or contradicts. The exploration ends with a Weave: a synthesis of the threads and candidate permanent-note seeds.

Loop Compatibility Contract

This skill is designed to be driven by a loop (/loop, /trinity:loop, or manual re-invocation):

  • One perspective pass per invocation (single-task rule; each pass completes in well under 10 minutes)
  • All state lives in the topic file - safe across separate context windows; no in-session memory assumed
  • Fixed reply format (Step 7) so {{previous_response}} chaining and Until-mode sentinels work
  • [[DONE]] appears in the reply if and only if the topic file's status is woven - tied to verifiable file state, not self-assessment
  • Idempotent on woven topics - re-invoking a finished topic re-reports the Weave and [[DONE]] without writing anything

State Dependencies

Source Location Read Write Description
Topic file Brain/05-Meta/Thinking/Freeform/[slug].md Perspective passes + frontmatter state
Local Brain Search resources/local-brain-search/ Semantic search (--no-track)
Permanent notes Brain/02-Permanent/ Evidence + wildcard lens source
MOCs Brain/03-MOCs/ Hub lens grounding

Deliberately NOT in THINKING-REGISTRY.md - freeform topics are invisible to the incubation loop. The two engines never touch each other's state. If a Weave concludes the topic deserves rigorous treatment, promote it manually via /manage-thinking-topics.

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.
