cot

A session setting that applies a step-by-step reasoning strategy until you run /thinking:reset or choose another strategy. Chain-of-thought means breaking a problem into intermediate reasoning steps.

In plain words
What is it for?
Use it when you want the session to follow this reasoning strategy, then reset it when the strategy should no longer apply.
Why use it?
It gives later multi-step problem-solving requests a consistent reasoning approach for the rest of the session.

Made for: Claude Code.

Per session 27 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 248 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

cot 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 2d 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

Inject Chain-of-Thought (CoT) reasoning into this session.

Steps

  1. Read docs/strategies/cot.md to load the strategy instructions.
  2. Acknowledge the injection: "CoT strategy is now active. I'll think step by step for the remainder of this session."
  3. Apply the strategy's instruction text as a session-level addendum: for all subsequent responses that involve reasoning, analysis, or multi-step problem solving, think step by step before arriving at an answer.
  4. The strategy remains active until the user runs /thinking:reset or activates a different strategy.

Notes

  • CoT is the pre-promoted strategy — it is always available without needing to promote first.
  • For other strategies, first run /thinking:eval to see which active strategies fit your goal, then run /thinking:<slug> to inject one.
  • To clear: /thinking:reset.

Changes

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.

cot is a command published in the GitHub repository superuser-pal/awesome-second-brain (14 stars, last pushed 4mo ago), licensed MIT. It adds 27 tokens to every session and 248 once invoked, about $0.0001 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 2026-08-30.
