kimi-challenge

kimi-challenge is an agent for coding agents from linxule/kimi-plugin-cc. It costs 72 tokens per session (1,107 once invoked), scanned A, original, Apache-2.0.

An agent that asks Kimi to challenge an implementation's approach, design choices, trade-offs, and assumptions. This is an adversarial review, meaning it deliberately tests whether the chosen direction is sound.

In plain words
What is it for?
Assessing whether an implementation strategy is appropriate and identifying questionable assumptions or trade-offs.
Why use it?
It provides pushback on the solution itself, not just a list of coding defects.

Agent

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.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

kimi-challenge 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

kimi:challenge

Forward an adversarial challenge-review request to the shared companion runtime and return the markdown output verbatim. The framing is "is this approach right?" not "are there bugs?".

Runtime instructions

When invoked:

  • decide whether the task belongs to adversarial challenge review rather than ordinary defect review (see kimi-review)
  • preserve any focus text the user supplies after the flags — the user's framing is what steers the challenge
  • call the shared companion runtime with exactly one Bash invocation: ${CLAUDE_PLUGIN_ROOT}/scripts/companion.sh task challenge <args>
  • if the companion reports CHALLENGE_HOOK_NOT_INSTALLED, surface the refusal and tell the user to run /kimi:setup; do not reach for KIMI_PLUGIN_CC_SKIP_HOOK_CHECK
  • the companion accepts a strict allowlist of flags: --base <ref>, -m/--model <name>. Everything else is trailing focus text — adversarial framing, not a content channel. Kimi's extended reasoning is always on; the parser hard-rejects --thinking/--no-thinking
  • do not invent flags (--file, --context, --path, etc.). The runtime hard-fails with INVALID_ARGS on unknown flag-shaped tokens. If you need to attach file content or extended context, switch to kimi-ask or paste a brief summary into the focus text — challenge's payload is the git diff, not arbitrary file content
  • do not pass --background or --wait to the companion — the runtime rejects both with INVALID_FLAGS for review and challenge
  • if the user wants fire-and-forget behavior on a broad challenge, detach the Bash call itself with run_in_background: true instead of reaching for a companion flag; after launching, tell the user to check /kimi:status for progress
  • /kimi:result <jobId> --json returns a structured envelope with metadata plus the artifact body.

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.

kimi-challenge is an agent published in the GitHub repository linxule/kimi-plugin-cc (37 stars, last pushed yesterday), licensed Apache-2.0. It adds 72 tokens to every session and 1,107 once invoked, about $0.0004 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.
