Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md.

This is samibs/skillfoundry's own configuration. It tells Claude Code how to work on skillfoundry 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 skillfoundry 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 C, and why

skillfoundry CLAUDE.md scanned grade C with 2 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 1mo 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

CLAUDE.md — SkillFoundry Framework Project Instructions

For universal AI agent rules (security, testing, LLM guardrails, workflow preferences): see ~/.claude/CLAUDE.md For production operations (PM2, caching, APM, migrations, incident response): see docs/enterprise-standards.md For AI-specific security anti-patterns: see docs/ANTI_PATTERNS_DEPTH.md and docs/ANTI_PATTERNS_BREADTH.md For environment pre-flight discipline (interpreter pinning, .env safety, diagnostic mode): see agents/_env-preflight-protocol.md For codebase comprehension pre-flight (Code Map: contract surface, import graph, DB/layer map — runs before implementing): see agents/_codemap-preflight-protocol.md For coding discipline (think-before-code, simplicity, surgical changes, goal-driven execution): see agents/_coding-discipline.md For delivery efficiency (delivery budgets, risk-based validation, evidence reuse, test scopes, stop conditions): see agents/_delivery-efficiency.md For parallel/multi-agent execution, dependency waves, git worktree isolation, process ownership, evidence, provenance, and the machine-readable .ai/ ledger: see MULTI_AGENT_PROTOCOL.md (operational module: agents/_governed-mission-protocol.md)

This file contains framework-specific rules only. General agent behavior is inherited from the global CLAUDE.md.

Philosophy

  • Cold-blooded logic over flattery: No vague encouragement or optimistic assumptions — honest, structured, production-ready evaluations only.
  • ONLY REAL LOGIC: No placeholders, no TODOs, no mocks, no stubs, no "coming soon", no fake data. Every feature must work end-to-end with real implementations.
  • Three-Layer Completeness: Every feature must be verified across DATABASE → BACKEND → FRONTEND before it's considered done.
  • PRD-First Development: Every non-trivial feature starts with a Product Requirements Document. No PRD = no implementation.
  • Implement > Test > Iterate: Every feature must be tested before being considered done.
  • Never break existing features: New features must not cause regressions.
  • Document everything: All modules and changes must include developer- and user-level documentation.
  • Clean project structure: When work is complete, organize files properly — root folder contains only essentials.

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.
