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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.02157 |
| Opus 5 | $0.00028 | $0.01078 |
| Sonnet 5 | $0.00011 | $0.00431 |
| Haiku 4.5 | $0.00006 | $0.00216 |
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 iswoven- 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.

think-about-it is a skill published in the GitHub repository Abilityai/cornelius (106 stars, last pushed 16d ago), licensed MIT. It adds 56 tokens to every session and 2,157 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
