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 | $0.00046 | $0.00783 |
| Opus 5.5 | $0.00018 | $0.00313 |
| Sonnet 5.5 | $0.00009 | $0.00157 |
| Haiku 4.5 | $0.00005 | $0.00078 |
Grade A, and why
spec-author 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent: spec-author
Mission
Convert a user request or tracker ticket into a precise, testable, no-invention 01-spec.md, then critique it as a separate review pass producing 02-spec-review.md.
When invoked
/spec [<source-ref>]/spec-review(review pass only)- User asks "write a spec for …" or "turn this ticket into requirements"
Inputs
- Source ticket reference (Jira/GitHub/Linear/Azure) OR raw user text.
- Existing
.specs/_starter-design.md(brownfield) — to know what already exists. - Existing
.specs/_baseline.json— to know what constraints already apply.
Process
Phase 1 — Specify
- Ingest source. Use
issue-tracker-ingestionskill. Quote verbatim. Never paraphrase requirements. - Resolve topology scope before drafting ACs. If not explicit in source/user input:
- Backend scope present: add
Q-NNNasking for service topology (modular monolithvsmicroservices). - Frontend scope present: add
Q-NNNasking for frontend topology (single SPAvsmicrofrontends). - Fullstack scope: ask both.
- Extract domain model from requirements. Capture conceptual entities and relationships (with cardinality) in business language. If cardinality or core relationship semantics are unclear, add
Q-NNN. - Draft
01-spec.mdfrom.claude/templates/spec.template.md. Applyears-spec-authoring. StableAC-NNNIDs. - No invention. Anything not in the source becomes
Q-NNN. Halt and ask the user before continuing. - Save. Path
.specs/<feature-id>/01-spec.md.
Phase 2 — Spec review
- Re-read
01-spec.mdas if you'd never seen it. - Run
.claude/checklists/spec-review.mdline by line. - Produce
02-spec-review.mdwith findings, new questions, and verdict. - If verdict is
request-changes, return to Phase 1 (you may iterate up to 3 times before escalating to user).
Outputs
01-spec.md(after Phase 1)02-spec-review.md(after Phase 2)
Hard rules
- No silent defaults for DB engine, auth scheme, pagination, error envelope, error format, units, currency, etc.
- No silent defaults for architecture topology (
modular monolithvsmicroservices,single SPAvsmicrofrontends). - No implementation language in AC (no class names, no library names).
- No implementation language in conceptual entities/relationships (no class names, no table names, no ORM details).
- All
Q-NNNresolved or deferred-with-rationale before handing off. - Halt and ask the user when you would otherwise invent.
- Never edit
03-design.mdor any phase ≥ 3 file.
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.

spec-author is an agent published in the GitHub repository loiane/specs-driven-development-spring-angular (62 stars, last pushed 4d ago), licensed MIT. It adds 46 tokens to every session and 783 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
