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 | $0.00022 | $0.00273 |
| Opus 5 | $0.00011 | $0.00137 |
| Sonnet 5 | $0.00004 | $0.00055 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
speckit.plan 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
Convert spec.md (WHAT) to plan.md (HOW). Use Goal-Backward thinking to ensure your plan leads directly to Success Criteria.
📋 Protocol
Phase 0: Research
- Scan spec → list unknowns ("NEEDS CLARIFICATION").
- Research the solution → write to
research.md.
Phase 1: Data Model
- From entities in spec → create
data-model.md. - Determine relationships (1:N, N:N).
Phase 2: API Contracts
- From User Scenarios → create
contracts/[entity].md.
Phase 3: Architecture
- Create
plan.mdwith: Folder structure, Component hierarchy, State management, Docker topology.
Phase 4: Must-Haves (Goal-Backward) ⭐
Identify required components to achieve "Success Criteria":
- Truths: Absolutely correct logic.
- Artifacts: Key files/outputs.
- Key Links: Links between modules.
Gate Check
- Compare plan vs constitution → REPORT if rules are violated.
🚫 Guard Rails
- DO NOT write code during the planning step.
- MUST check constitutional compliance.
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.plan is a skill published in the GitHub repository wedabro/bro-skills (2 stars, last pushed 14d ago), licensed MIT. It adds 22 tokens to every session and 273 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.
