What is agent-instructions CLAUDE.md?

Repository instructions for a system that generates slash commands for AI coding agents from reusable text fragments.

Use them to edit command sources or fragments, handle optional features such as beads, generate local commands, and maintain committed build outputs.

They explain how to keep shared command content in one source and prevent generated commands from drifting apart.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01813	$0.01813
Opus 5.5	$0.00725	$0.00725
Sonnet 5.5	$0.00363	$0.00363
Haiku 4.5	$0.00181	$0.00181

Security

Grade B, and why

agent-instructions CLAUDE.md scanned grade B with 1 finding 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 2mo 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

- **Never** use wildcard patterns like `Bash(git:*)` or `allowed-tools: *`

Claude Instructions Repository

Note: This file contains instructions for managing THIS repository. Users installing the commands should NOT copy this file - it's for maintainers only.

GitHub URL: https://github.com/wbern/agent-instructions (NOT KenDev-AB)

This repository contains a fragment-based system for generating slash commands for AI coding agents (Claude Code, OpenCode) with TDD focus.

Architecture

Fragment System

Sources (src/sources/*.md): Command templates with INCLUDE directives only
Fragments (src/fragments/*.md): Reusable content blocks
Local commands (.claude/commands/, .opencode/commands/): Generated commands for local development
Dynamic generation: CLI generates commands on-the-fly with optional feature flags (e.g., beads)

Key Principles

Single source of truth: Content lives in fragments, not sources
Clean sources: Source files contain only INCLUDE directives, never expanded content
Track artifacts: Both sources and built commands are committed for easy distribution
Feature flags: Use featureFlag='beads' for conditional content

Contributor Commands

Source files prefixed with underscore (_*.md) are "contributor commands":

Excluded from npm package distribution (consumers never see them)
Included in this repo's local commands for maintainers
Underscore prefix is stripped from output filename (_foo.md → foo.md)
Not listed in README command list
Use --include-contrib-commands internal flag to include them

Development Workflow

Package Manager

Use pnpm for all package operations

Common Commands

pnpm build          # Build README.md and local commands
pnpm test           # Run tests
pnpm vitest run -u  # Update snapshots

Git Hooks (Husky)

Pre-commit hook automatically:

Builds (includes markdownlint --fix)
Runs tests
Stages generated files (README.md, generated commands)

This ensures artifacts are always in sync with sources.

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.

agent-instructions CLAUDE.md is an instructions file published in the GitHub repository wbern/agent-instructions (168 stars, last pushed 5mo ago), licensed MIT. It adds 1,813 tokens to every session, about $0.0073 per session on Opus 5.5. A static security scan graded it B with 1 finding (unrestricted tool access).
