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 | $0.01678 |
| Opus 5.5 | $0.00000 | $0.00671 |
| Sonnet 5.5 | $0.00000 | $0.00336 |
| Haiku 4.5 | $0.00000 | $0.00168 |
Grade A, and why
spec-create 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: spec-create
Purpose
Produce a .specs/<name>.md that is complete enough for spec-validator to flip to status: approved. The user runs /spec-create <name> (optionally with --figma <url>); this skill drives the interaction.
When to invoke
- The slash command
/spec-createwas used. - The user said "I need a new component" / "criar componente" but there is no
.specs/<name>.mdyet, and/component-createwas about to fail because of that.
Inputs & mode
<name>(kebab-case) — required in Mode B; optional in Mode A. In Mode A (Figma), when<name>is omitted the name is derived from the frame's component name (normalized to kebab) and confirmed with the user; a passed<name>overrides the frame. See Name resolution in the Mode A section.- The mode is chosen by input:
- Mode A — Figma-driven:
--figma <url>is present. The frame is the source of truth. - Mode B — Name + Category: no
--figma. The user is building without a design;--category <name>is required (ask + confirm if missing). This mode is more blocking — see below.
- Mode A — Figma-driven:
Confirm the mode with the user before drafting. If it's ambiguous which one they want, ask.
Workflow — shared steps
- Argument parsing & name resolution. Parse the flags. A passed
<name>must be kebab-case (reject otherwise) and always wins (explicit override). If<name>is absent: in Mode B reject (no frame to derive from); in Mode A defer — the name is resolved from the frame in Name resolution below, before any file path is computed. Only once the name is known: reject if.specs/<name>.mdalready exists withstatus ∈ {approved, implemented, locked}(the user is editing the wrong file) and ask for a different name. - Category. Use the taxonomy in
.specs/_template.mdfrontmatter. State the inferred/received category and ask the user to confirm (mandatory in Mode B — never assume). - Structure decision. Call
structure-decidewith the regions/answers. Default tomonolithicwhen in doubt. - Write the spec. Copy
.specs/_template.mdto.specs/<name>.md, fill every section, frontmatterstatus: draft,created/last_updated= today, nochecksum. - Echo. Print the path. Tell the user to review it, then run
/component-create <name>(which callsspec-validator) or setstatus: approvedand re-run.
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-create is a skill 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 1,678 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.
