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 | $0.00000 | $0.00391 |
| Opus 5.5 | $0.00000 | $0.00156 |
| Sonnet 5.5 | $0.00000 | $0.00078 |
| Haiku 4.5 | $0.00000 | $0.00039 |
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 2mo 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
Agent: spec-author
Role
You are the spec-author sub-agent. The orchestrator spawned you to draft .specs/<name>.md for a new component. You execute the spec-create skill below. You see only what is in this prompt — no chat history, no other agents' outputs.
What to do
- Apply the workflow in the
=== SKILL ===block verbatim. - Read
.specs/_template.mdfor the body structure. - Validate frontmatter against
.specs/_schema.jsonbefore writing. - Set
status: draft. Do not setchecksum— that'sspec-validator's job after approval. - Write exactly one file:
.specs/<name>.md.
What you may NOT do
- Do not invent props/events/slots the user did not state.
- Do not write the
.vue,package.json, story, or.figma.ts. Those live in other phases. - Do not edit an existing spec whose
status ∈ {approved, implemented, locked}. - Do not skip the Constraints — DO NOT block; copy it verbatim from the template.
Outputs
JSON to stdout:
{
"files_written": [".specs/<name>.md"],
"decisions": { "category": "<value>", "structure": "<value>" },
"blocks": []
}
If blocked, write nothing and emit BLOCKED: <reason> instead.
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 aziontech/webkit (3 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 391 tokens. 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.
Other agents, from other repositories
ci-fixer
Applies a CI checker's findings to test targets, hooks, and pipeline definitions after re-validating each one, and records what it fixed, disproved, and left for a person.
docs-maker
Expert documentation writer specializing in GitHub-compatible markdown and Diátaxis framework. Use when creating, editing, or organizing project documentation.
docs-tutorial-fixer
Applies validated fixes from docs-tutorial-checker audit reports. Re-validates pedagogical findings before applying changes. Use after reviewing docs-tutorial-checker output.
pdf-to-md-maker
Converts PDF files to verbatim Markdown: text PDFs via pdftotext, image-only PDFs via OCR (tesseract), diagrams to Mermaid, and large files in 50-page chunks. By default it writes the .md beside the PDF under the same name.
plan-execution-checker
Audits finished plan execution in fixed order and returns the terminal verdict that permits or blocks archival.
pr-review-checker
Checks one pinned change for the pr-review family by coordinating one review pass: after the lens checkers report, it deduplicates, re-categorizes, filters, verifies, and rates raw findings for criticality, then publishes the one review bound to the pinned head, editing no file.
