codebase-standards

A project skill that finds, indexes, and applies coding standards and recurring patterns from a codebase. It can also guide product planning and feature specifications using those conventions.

In plain words
What is it for?
It helps document conventions, load them into planning work, rebuild a standards index, define products, and write feature specifications.
Why use it?
It reduces the need to rediscover a project’s rules and style before planning or changing code.

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

codebase-standards 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.

How it starts

The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codebase Standards — Skill

Adapted from Agent OS by Brian Casel. Auto-discover, index, and inject coding standards from any codebase. Plan products and shape feature specs with standards-aware context.

Available Commands

Command Trigger Reference
Discover Standards "discover standards", "extract conventions", "document patterns" references/discover-standards.md
Inject Standards "inject standards", "load standards", "apply conventions" references/inject-standards.md
Index Standards "rebuild index", "update standards index" references/index-standards.md
Plan Product "plan product", "define product", "product mission" references/plan-product.md
Shape Spec "shape spec", "plan feature", "spec out" references/shape-spec.md

How It Works

  1. Read the relevant reference file for the command being invoked
  2. Follow the reference instructions step by step
  3. Interact conversationally — ask the user questions directly (no special tools needed)
  4. Write files to the project's standards/product/specs directories

Workspace Conventions

All files are stored relative to the target project root (not the agent workspace):

{project}/
├── agent-os/
│   ├── standards/          # Discovered coding standards
│   │   ├── index.yml       # Standards index for quick matching
│   │   ├── api/            # Standards by area
│   │   ├── database/
│   │   ├── frontend/
│   │   └── global/
│   ├── product/            # Product documentation
│   │   ├── mission.md
│   │   ├── roadmap.md
│   │   └── tech-stack.md
│   └── specs/              # Feature specifications
│       └── {YYYY-MM-DD-HHMM-feature-slug}/
│           ├── plan.md
│           ├── shape.md
│           ├── standards.md
│           └── references.md

If the project root is the current workspace ($HOME/clawd), files go in ./agent-os/. If working on a different project, ask the user for the project path first.

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

codebase-standards is a skill published in the GitHub repository MuduiClaw/ClawKing (11 stars, last pushed 4mo ago), licensed MIT. It adds 48 tokens to every session and 787 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 2026-08-30.
