What it does

Thinking Circle Of Competence is an agent skill from tjboudreaux/cc-thinking-skills. Use when a specific claim may lack grounding. Check evidence boundary, size wrongness cost, then answer, fetch, or abstain — never confabulate.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 28 eval-informed mental models and critical-thinking skills for Claude Code, GitHub Copilot, Codex, Cursor, and other Agent Skills-compatible tools. The licence is MIT.

When your agent uses it

  • A specific claim may lack grounding

Example prompts

  • “/thinking-circle-of-competence”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Name the claim. Isolate the assertion that would be treated as fact.
  2. Classify the zone.
  3. Size wrongness cost. If high-stakes (security, data loss, irreversible ops), treat Partial as Ungrounded until verified.
  4. Act by zone.
  5. Refuse competence creep. Adjacent code, prior versions, or general capability do not ground the unread target.
  6. Stop. Emit answer, fetch request, or abstention. Do not round "probably" to a flat assertion.

What it can do on your machine

Read from SKILL.md and the folder at commit 7b8fece. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Thinking Circle Of Competence loads about 733 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 355 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~733

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Circle of Competence

Treat competence as an evidence boundary, not self-image. Answer only when grounded; otherwise fetch, mark uncertainty, or abstain. The failure mode is a fluent fabrication treated as fact.

When to Use

  • About to assert a specific fact (API, path, number, config, version behavior) without a citable source from this session.
  • The claim is about this codebase or system and you have not read or run the relevant artifact.
  • Pattern reconstruction would sound complete but is unconfirmed.
  • Cost of a wrong confident answer is material (security, data, irreversible action, trust).

When NOT to Use

  • Claim is grounded in something you read, ran, or can cite this session, or is stable universal knowledge — answer without false humility.
  • Error cost is trivial and reversible and you will flag the claim as unverified.
  • Grounding is one cheap fetch away — fetch first; abstention is not an excuse to skip a check.
  • User explicitly wants labeled brainstorming or hypotheticals.

Procedure

  1. Name the claim. Isolate the assertion that would be treated as fact.
  2. Classify the zone.
    • Grounded: citeable session source (read/run) or stable non-version-specific knowledge.
    • Partial: general shape known; version/repo/config detail unconfirmed.
    • Ungrounded: would invent a concrete value with no source.
  3. Size wrongness cost. If high-stakes (security, data loss, irreversible ops), treat Partial as Ungrounded until verified.
  4. Act by zone.
    • Grounded → answer; cite when useful; do not hedge verified facts.
    • Partial → cheap fetch then answer; else answer only with explicit uncertainty and a check path.
    • Ungrounded → fetch if possible; else ask or abstain with what would enable an answer. Never invent.
  5. Refuse competence creep. Adjacent code, prior versions, or general capability do not ground the unread target.
  6. Stop. Emit answer, fetch request, or abstention. Do not round "probably" to a flat assertion.

Stop condition: Claim answered with grounding, marked partial with a check path, or refused with missing-evidence note.

Output

text
Claim: <assertion>
Zone: grounded | partial | ungrounded
Evidence: <source or none>
Wrongness cost: low | medium | high
Action: answer | fetch-then-answer | answer-with-uncertainty | abstain/ask
Response: <wording or missing artifact>

Verification

  • Falsify if a specific value was asserted with no session source and no uncertainty marker.
  • Falsify if Partial/high-stakes was treated as Grounded, or a cheap fetch was skipped for abstention theater.
  • Over-application guard: do not hedge or refuse claims verified this session.
