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 5.1 | $0.00021 | $0.00509 |
| Opus 5 | $0.00010 | $0.00254 |
| Sonnet 5 | $0.00004 | $0.00102 |
| Haiku 4.5 | $0.00002 | $0.00051 |
Grade A, and why
speckit.constitution 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 10d 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
🎯 Mission
Create and maintain constitution.md — the "supreme law" that every agent must comply with.
📥 Input
- Developer provides: tech stack, principles, constraints
.agents/knowledge_base/infrastructure.md(if available)
📋 Protocol
- Collected from developers:
- Tech stack (frameworks, DB, language)
- Docker ports (cấu hình qua biến môi trường)
- Coding principles (VD: No hardcode, API-first)
- Security requirements
- Create/update
.agents/memory/constitution.mdwith REQUIRED sections:- §1 Infrastructure: Docker-first policy, port allocation, environments
- §2 Security: No root containers, no hardcoded secrets, multi-stage builds
- §3 Code Standards: Language, naming conventions, ENV policy
- §4 Non-Negotiables: List of rules that should NEVER be violated
- §5 Monorepo Rules (if monorepo):
- Shared Package Contract: type exports is the source of truth
- Build Independence: each app must be compiled independently
- Package exports must match actual file structure
- §6 Docker Deployment Rules:
- Volume shadowing (
- .:/app) is PROHIBITED in production/beta - Dockerfile COPY paths must exist
- CMD entrypoint must match build output
- Next.js apps must have a
public/folder
- Volume shadowing (
- §7 Build-time Safety (if Next.js):
- SSG pages (sitemap, generateStaticParams): API calls must be try-catch
- fetchApi must return null/empty if API_URL is undefined
- §8 Pre-Deploy Checklist:
docker compose buildsucceeded- All services
Up(notRestarting) - Health check: 200 OK
- Validate: Each section must have at least 1 specific rule, not general.
📤 Output
- File:
.agents/memory/constitution.md
🚫 Guard Rails
- Constitution does NOT contain implementation details (HOW) — only rules (WHAT).
- Each rule must be testable (can be verified with code/check).
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.

speckit.constitution is a skill published in the GitHub repository wedabro/bro-skills (2 stars, last pushed 14d ago), licensed MIT. It adds 21 tokens to every session and 509 once invoked, about $0.0001 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 2026-08-31.
