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 | $0.00008 | $0.02008 |
| Opus 5 | $0.00004 | $0.01004 |
| Sonnet 5 | $0.00002 | $0.00402 |
| Haiku 4.5 | $0.00001 | $0.00201 |
Grade A, and why
autospec.checklist 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.
How it starts
The opening of the file, as written. The whole thing — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Checklist Purpose: "Unit Tests for English"
CRITICAL CONCEPT: Checklists are UNIT TESTS FOR REQUIREMENTS WRITING - they validate the quality, clarity, and completeness of requirements in a given domain.
NOT for verification/testing:
- NOT "Verify the button clicks correctly"
- NOT "Test error handling works"
- NOT "Confirm the API returns 200"
- NOT checking if code/implementation matches the spec
FOR requirements quality validation:
- "Are visual hierarchy requirements defined for all card types?" (completeness)
- "Is 'prominent display' quantified with specific sizing/positioning?" (clarity)
- "Are hover state requirements consistent across all interactive elements?" (consistency)
- "Are accessibility requirements defined for keyboard navigation?" (coverage)
- "Does the spec define what happens when logo image fails to load?" (edge cases)
Metaphor: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works.
User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Pre-computed Context
The following paths have been pre-computed and are available for use:
- FEATURE_DIR:
{{.FeatureDir}} - FEATURE_SPEC:
{{.FeatureSpec}}
Execution Steps
-
Clarify intent (dynamic): Derive up to THREE initial contextual clarifying questions. They MUST:
- Be generated from the user's phrasing + extracted signals from spec/plan/tasks
- Only ask about information that materially changes checklist content
- Be skipped individually if already unambiguous in
$ARGUMENTS - Prefer precision over breadth
Generation algorithm:
- Extract signals: feature domain keywords (e.g., auth, latency, UX, API), risk indicators ("critical", "must", "compliance"), stakeholder hints ("QA", "review", "security team")
- Cluster signals into candidate focus areas (max 4) ranked by relevance
- Identify probable audience & timing (author, reviewer, QA, release) if not explicit
- Detect missing dimensions: scope breadth, depth/rigor, risk emphasis, exclusion boundaries
- Formulate questions from these archetypes:
- Scope refinement (e.g., "Should this include integration touchpoints?")
- Risk prioritization (e.g., "Which risk areas need mandatory gating checks?")
- Depth calibration (e.g., "Lightweight sanity list or formal release gate?")
- Audience framing (e.g., "Author-only or peer PR review?")
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.

autospec.checklist is a command published in the GitHub repository ariel-frischer/autospec (141 stars, last pushed 1mo ago), licensed MIT. It adds 8 tokens to every session and 2,008 once invoked, about $0.0000 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 2026-08-30.
Other commands, from other repositories
speckit.companion.implement
Companion implement — execute tasks.md in dependency order, then mark complete.
speckit.companion.plan
Companion plan — implementation plan with research & design artifacts.
speckit.companion.doctor
Report on a spec's run health — unfinished steps, unjournaled tasks, step bleed, drift you can judge, a step that closed having verified nothing, a step that closed without the file it promised, and why completion did not land (read-only, retroactive, never halts).
speckit.companion.living-move
Move a living spec between central and colocated storage — file, tiers, and registry together (opt-in, reversible).
speckit.companion.living-validate
Check the shape of living specs and a feature spec's deltas — a requirement with no scenario, a scenario missing WHEN or THEN, a duplicate heading, a delta pointing at nothing (opt-in, read-only, never halts).
speckit.companion.after-specify
Capture the current spec-kit step into .spec-context.json for the Companion GUI.
