Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00087 | $0.03615 |
| Opus 5 | $0.00044 | $0.01808 |
| Sonnet 5 | $0.00017 | $0.00723 |
| Haiku 4.5 | $0.00009 | $0.00362 |
Grade A, and why
seed-conventions 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 today.
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 — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Seed Conventions
HARD GATE — Before any new code lands, confirm the project conventions are understood. Ask: 'What does a good commit message look like in this project?'
Bootstrap a new project with the AI agent conventions it needs. Run this once at the start of a greenfield project.
What this creates
CLAUDE.md— Claude Code session config (project-specific)CONVENTIONS.md— shared rules for all AI agentsspecs/— the specs directory where all planning output will liveAGENTS.md— for OpenCode and other agents (optional)GEMINI.md— for Gemini CLI (optional)
Interview
Ask the user these questions (one at a time, wait for each answer):
- Project name and one-sentence description — "What is this project? One sentence."
- Stack — "What language, framework, and runtime? (e.g. TypeScript / Next.js / Node 22)"
2b. Stack profile (optional) — Offer:
swift,typescript-vue,node-service, or none. If chosen, merge the matching fragment fromprofiles/<name>.mdinto generatedCONVENTIONS.md. - Commands — "What commands do you use for: run, test, build, lint?" 3b. Preflight (optional) — "What command runs test, lint, and build together? If none, chain Test + Lint + Build into one Preflight row."
- Architecture — "Key modules and relationships in 1–2 sentences."
- Conventions — "Any naming, file organization, or patterns all agents must follow?"
- Never-do list — "What are the hard stops? Things an agent must never touch?"
- Defensive code categories — "Which apply? (Rate limit / Retry / Circuit breaker / Timeout / Graceful degradation)"
- Local tool wiring (optional) — "Wire bigpowers for project-local tools? (Cursor, OpenCode, Cline, Aider, Codex CLI)" If yes, generate AGENTS.md spine artifacts per REFERENCE.md §Local tool wiring and §AGENTS.md spine. If no, skip — standard seed output unchanged (no AGENTS.md spine unless opted in).
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.

seed-conventions is a skill published in the GitHub repository danielvm-git/bigpowers (163 stars, last pushed 3d ago), licensed MIT. It adds 87 tokens to every session and 3,615 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

debloat
Compress an artifact that has accreted into bloat — padding, over-qualification, fused sentences, walls of enumeration, adjacent restatement — down to its load-bearing density, meaning preserved. Use when prose is correct and current but has grown verbose or patched-over and you want it tight without a full rewrite.
bmad-validate-prd
Validate a PRD against standards. Use when the user says "validate this PRD" or "run PRD validation".
ship
Validate a branch, run quality gates, update documentation and changelog, and open a pull request. Supports GitHub (primary) and Azure DevOps (secondary). Designed for JavaScript/TypeScript projects; quality gate detection requires package.json. Use when the user says "ship", "ship this", "open a PR", "prepare a PR"…
