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

dev-pack 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 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.

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

CLAUDE.md — working ON dev-pack

This is the repo for the pack itself. (For using the pack in your project, run an installer — see README.)

What this repo is

A curated, enforced Claude Code pack for database + website builders on Next.js + Supabase. Layers: rules/ (advisory) · skills/ (on-demand) · hooks/ (deterministic) · loops/ (slash commands) · agents/ (subagents) · mcp/ · templates/. Full list in INVENTORY.md.

House rules for changing this repo

  • Every item must serve a stated goal: fewer tokens, accuracy, truth-telling, speed, quality.
  • Hooks must be tested. Add a case to tests/test_hooks.py and run it: python tests/test_hooks.py. State the fail mode (open/closed) in the hook docstring.
  • Keep rule/skill files short — they cost tokens every turn.
  • No inflated claims anywhere. Anything documented as working must actually have been run. This repo practices the truth-telling it preaches.
  • Update INVENTORY.md and CHANGELOG.md when adding/removing items.

Verify

python tests/test_hooks.py        # all hook behavior
python -c "import json;json.load(open('hooks/settings.json'))"   # config valid

Conventions

  • Commit format: <type>: <description> (feat/fix/docs/refactor/test/chore).
  • Hooks are Python 3.8+ (cross-platform). One logical change per PR.
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.
