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.

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 | $0.00035 | $0.01977 |
| Opus 5 | $0.00017 | $0.00988 |
| Sonnet 5 | $0.00007 | $0.00395 |
| Haiku 4.5 | $0.00003 | $0.00198 |
Grade A, and why
project-brief 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 10d 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 — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Brief — Task-Focused Code Navigation
Purpose
Generate a task-focused project brief for a specific module, feature, bug, or directory. This is a lightweight complement to /init:
/init |
project-brief |
|
|---|---|---|
| Scope | Whole project | Specific module / feature / directory |
| Output | AGENTS.md (persistent) |
In-conversation brief (temporary) |
| Purpose | Help AI understand project conventions | Help you navigate unfamiliar code for a task |
| When | First time onboarding a project | Before modifying a specific area |
This skill does not generate AGENTS.md or any persistent files. It produces a focused, in-conversation brief that helps you understand the code around your current task.
Kimi Code Usage
Manual invocation:
/skill:project-brief
/skill:project-brief auth
/skill:project-brief src/api/routes.ts
This skill may be automatically invoked when the user asks to understand a module or navigate unfamiliar code.
Kimi Code Behavior
This skill is read-only.
- Do not edit, create, delete, format, or initialize files.
- Do not run
/init. - Do not generate or modify
AGENTS.md.
Input
Target: $target
If $target is empty, ask the user what module, feature, file, directory, or bug they want to understand.
The target can be:
- A module or package name:
auth,user-service,payment - A file path:
src/api/routes.ts - A feature name:
login flow,search functionality - A bug or error reference:
the null pointer in user.ts - A directory:
src/components/ - A concept:
how caching works
Workflow
1. Identify the Target
Parse the user's input to determine:
- What: module name, file, feature, or concept
- Scope: narrow (single file) or broad (entire module)
2. Locate Relevant Files
Prefer tracked files first. Treat the target as a literal string, not a shell expression or regex.
Safe pattern:
git ls-files | rg -i --fixed-strings -- '<literal-target>'
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.

project-brief is a skill published in the GitHub repository FeiZhuLulu/kimi-code-skills (5 stars, last pushed 2mo ago), licensed MIT. It adds 35 tokens to every session and 1,977 once invoked, about $0.0002 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 2026-08-31.
