scraps: Instructions file for Claude Code

AGENTS.md

scraps AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from boykush/scraps. It costs 397 tokens per session, scanned A, original, MIT.

Repository-specific instructions for coding agents working on Scraps, a Rust project with a command-line interface and supporting libraries. They describe the project layout, workflow, tests, formatting, checks, and commit style.

In plain words
What is it for?
Use them when planning, editing, testing, formatting, or committing changes in Scraps. They direct agents to use test-driven development (write a failing test, make it pass, then improve the code) and to run the project's quality checks.
Why use it?
They give an agent the project's local rules instead of making it guess how files, tests, and changes should be handled. This helps preserve existing work and keeps changes consistent with the repository.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: PostToolUse hook event, but also the file is AGENTS.md.

This is boykush/scraps's own configuration. It tells Claude Code, Codex and OpenCode how to work on scraps itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything scraps configures →

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

scraps AGENTS.md 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 8d 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

Scraps Development with Coding Agents

For comprehensive guidelines, see CONTRIBUTING.md

Project Structure

  • Workspace: root crate (src/) + modules/libs/ (scraps_libs)
  • CLI commands: src/cli/cmd/<name>.rs using PathResolver + ScrapConfig
  • Usecases: src/usecase/<name>/usecase.rs
  • IR: src/ir/ (schema, store, loader) persists the compiled wiki under .scraps/ next to .scraps.toml; every command loads scraps through ir::loader
  • Libs features: error, git, lang, markdown, model, search — gated in modules/libs/src/lib.rs
  • Config language: PKL (*.pkl files)
  • Dogfooding: the jaeger MCP server reads the traces of the owner's own Scraps deployment. It is owner-only and called only from the dogfood skill; in any other work, leave mcp__jaeger__* alone
  • Discovery: livt/ is the product discovery workspace (livt); its content is written in Japanese by convention, while the rest of the repository is English

Development Workflow

  1. Plan: Start in Plan mode to analyze requirements and design approach
  2. Implement: One TODO at a time, following TDD (Red -> Green -> Refactor)
    • PostToolUse hook auto-formats .rs files on Edit/Write
    • Pre-commit hook runs cargo:quality (test + fmt + clippy) automatically
  3. Commit & PR: Write commit messages as Conventional Commits (see CONTRIBUTING.md)
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.
