reason

reason is a command for coding agents from satasuk03/kimi-plugin-cc. It costs 23 tokens per session (912 once invoked), scanned A, original, MIT.

A command that sends a difficult reasoning, software-design, or debugging question to a Kimi reasoning subagent. The subagent only investigates and reports; it does not edit files.

In plain words
What is it for?
Use it for architecture reviews, complex reasoning, and hard debugging investigations, either in the foreground or as a background job.
Why use it?
It gives you a separate analysis of problems that may need deeper investigation before you make changes.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

reason 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 3d 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

Invoke the kimi:kimi-reasoner subagent via the Agent tool (subagent_type: "kimi:kimi-reasoner"), forwarding the raw user request as the prompt. kimi:kimi-reasoner is a subagent, not a skill — do not call Skill(kimi:kimi-reasoner) (no such skill) or Skill(kimi:reason) (that re-enters this command and hangs the session). The command runs inline so the Agent tool stays in scope; forked general-purpose subagents do not expose it. The final user-visible response must be Kimi's output verbatim.

Raw user request: $ARGUMENTS

Core constraint:

  • This command is read-only. Kimi should investigate, analyze, and report — not edit files.

Execution mode:

  • If the request includes --background, run the kimi:kimi-reasoner subagent in the background.
  • If the request includes --wait, run the kimi:kimi-reasoner subagent in the foreground.
  • If neither flag is present, default to foreground.
  • --background and --wait are execution flags for Claude Code. Do not forward them to reason, and do not treat them as part of the natural-language request text.
  • --model is a runtime-selection flag. Preserve it for the forwarded reason call, but do not treat it as part of the natural-language request text.
  • If the request includes --resume, do not ask whether to continue. The user already chose.
  • If the request includes --fresh, do not ask whether to continue. The user already chose.
  • Otherwise, before starting Kimi, check for a resumable reasoning thread from this Claude session by running:
node "${CLAUDE_PLUGIN_ROOT}/scripts/kimi-companion.mjs" task-resume-candidate --json
  • If that helper reports available: true, use AskUserQuestion exactly once to ask whether to continue the current Kimi thread or start a new one.
  • The two choices must be:
    • Continue current Kimi thread
    • Start a new Kimi thread
  • If the user is clearly giving a follow-up instruction such as "continue", "keep going", "resume", or "dig deeper", put Continue current Kimi thread (Recommended) first.
  • Otherwise put Start a new Kimi thread (Recommended) first.
  • If the user chooses continue, add --resume before routing to the subagent.
  • If the user chooses a new thread, add --fresh before routing to the subagent.
  • If the helper reports available: false, do not ask. Route normally.

Operating rules:

  • The subagent is a thin forwarder only. It should use one Bash call to invoke node "${CLAUDE_PLUGIN_ROOT}/scripts/kimi-companion.mjs" reason ... and return that command's stdout as-is.
  • Return the Kimi companion stdout verbatim to the user.
  • Do not paraphrase, summarize, rewrite, or add commentary before or after it.
  • Do not ask the subagent to inspect files, monitor progress, poll /kimi:status, fetch /kimi:result, call /kimi:cancel, summarize output, or do follow-up work of its own.
  • Leave the model unset unless the user explicitly asks for one. When unset, the companion runs the reasoning job on Kimi K3 (kimi-code/k3); when the user names a model, pass the requested id through with --model <id>.
  • Leave --resume and --fresh in the forwarded request. The subagent handles that routing when it builds the reason command.
  • If the helper reports that Kimi is missing or unauthenticated, stop and tell the user to run /kimi:setup.
  • If the user did not supply a request, ask what Kimi should analyze, investigate, or reason about.

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.
