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 | $0.00018 | $0.00419 |
| Opus 5 | $0.00009 | $0.00210 |
| Sonnet 5 | $0.00004 | $0.00084 |
| Haiku 4.5 | $0.00002 | $0.00042 |
Grade A, and why
speckit.specify 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
Pass natural language description → standardized spec.md (WHAT, not HOW).
📥 Input
- Feature description from developer (free text)
.agents/memory/constitution.md(constraints)
📋 Protocol
- Read description → extract:
- Actors: Who interacts? (User, Admin, System, Guest)
- Actions: Do what? (CRUD, search, filter, export)
- Data: What data? (entities, fields, relationships)
- Constraints: What limits? (auth, permissions, limits)
- Create
.agents/specs/[feature]/spec.mdwith REQUIRED format:--- title: [Feature Name] status: DRAFT version: 1.0.0 created: [date] --- ## 1. Overview [1-2 sentence description] ## 2. User Scenarios - **US1**: As a [actor], I want to [action], so that [value]. - **US2**: ... ## 3. Functional Requirements - FR01: [specific, measurable requirement] ## 4. Non-Functional Requirements - NFR01: Response time < 2s ## 5. Success Criteria - [ ] SC01: [testable criterion] - Each User Scenario MUST have: Actor + Action + Value.
- Each Functional Requirement MUST be measurable (have specific data).
📤 Output
- File:
.agents/specs/[feature]/spec.md
🚫 Guard Rails
- DO NOT write implementation details (HOW) — just describe WHAT.
- DO NOT use technical jargon in User Scenarios (business language).
- DO NOT ignore error cases — each action must have a "what if it fails?"
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.specify is a skill published in the GitHub repository wedabro/bro-skills (2 stars, last pushed 14d ago), licensed MIT. It adds 18 tokens to every session and 419 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.
