Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; names the TodoWrite tool; mentions Claude Code.

This is incubrain/foundry's own configuration. It tells Claude Code how to work on foundry 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 foundry 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

foundry CLAUDE.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 14d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Guidance for Claude Code in this repository. Reference detail — architecture, file locations and workflows — lives in CONTEXT.md. Canonical terms are in GLOSSARY.md.

Project

Foundry (@incubrain/foundry) is a Nuxt 4 validation layer for technical founders — captures signal (email, presales, bookings) to prove demand before building product. See GLOSSARY.md for domain terms and CONTEXT.md for architecture, file locations, and day-to-day workflow (verdaccio cross-repo testing, module guides, visual testing).

Critical rules

  1. Never add features that don't capture signal. If it doesn't help founders validate faster, reject it.
  2. Never build custom when VueUse/library exists. Priority: VueUse → library → custom (last resort). Check composables.vueuse.org first.
  3. Validation ≠ Product. Email sequences, auth, payment processing, gated content are product features — out of scope.
  4. Complexity budget: max 50 lines per layer component (reusable); example-app components can run longer but extract composables at ~150 lines. Max 5 props, max 2 abstraction layers, max 3 nesting levels.
  5. Content in YAML/Markdown, not hardcoded. Customers edit content files, not code.
  6. Ship first, optimize later. Ship working → measure → optimize what data proves necessary.

Before building: does VueUse solve this? does an existing component handle it? is this a real (not imagined) problem? will it capture signal faster? If all four are "no," don't build it.

Issue tracking — beads (bd)

Beads Issue Tracker

This project uses bd (beads) for issue tracking. Run bd prime to see full workflow context and commands.

Quick Reference

bd ready              # Find available work
bd show <id>          # View issue details
bd update <id> --claim  # Claim work
bd close <id>         # Complete work

Rules

  • Use bd for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
  • Run bd prime for detailed command reference and session close protocol
  • Use bd remember for persistent knowledge — do NOT use MEMORY.md files

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.
