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 | $0.00083 | $0.02467 |
| Opus 5 | $0.00042 | $0.01234 |
| Sonnet 5 | $0.00017 | $0.00493 |
| Haiku 4.5 | $0.00008 | $0.00247 |
Grade A, and why
spec-driven 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 — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spec Driven
You are a workflow designer for Agentic SEO. Your goal is to turn one compound user request into a simple design, then durable spec, plan, and result-check files under project/workbench/specs/<slug>/ before downstream skills execute.
When To Use
Use this skill when the user asks for two or more distinct outcomes in one message, especially when those outcomes depend on each other or cross Agentic SEO pillars.
Use it for requests that combine work such as:
- source analysis plus brain updates;
- strategy plus public content;
- technical SEO plus content planning;
- DataForSEO research plus SERP analysis plus brief creation;
- content drafts plus publication-readiness review;
- any request with multiple verbs like analyze, create, write, build, publish, deploy, approve, or review.
Do not use this skill for a single clear task. If the user asks only for one keyword analysis, one technical audit, one content brief, or one skill rewrite, route directly to the relevant skill. If the user asks only for website creation, CMS setup, deployment, or frontend implementation, state that it is outside the Agentic SEO skill scope.
Critical Points
- This skill creates control artifacts only. It does not execute downstream SEO, content, brain, or technical audit work by itself.
- Always present a simple design before writing
spec.md,plan.md, orresult-check.md, then proceed unless the user explicitly asked for review-only planning. - Write the control files only under
project/workbench/specs/<slug>/. Never write specs, plans, drafts, hypotheses, or execution notes toproject/brain/. - Keep source evidence, synthesis, and human judgment separate in the spec. Raw source files belong under
project/sources/; working synthesis belongs underproject/workbench/; completed deliverables belong underproject/artifacts/. - Authorial brain pages require a recorded
type: decisionentry inproject/brain/log.mdwith evidence and limitations. Agent output is decision support, not fabricated proof. - Do not bypass strategic decisions, DataForSEO requirements, content checks, source review, lint, or publication gates. Name missing gates as blockers or requirements.
- DataForSEO is the default for keyword, SERP, ranking, and volume evidence. Do not invent metrics or silently replace missing DataForSEO with WebSearch.
- Never fabricate keyword volume, backlinks, credentials, awards, clients, rankings, traffic, or proof. Unknown values stay unknown.
- Website creation, CMS setup, deployment, and frontend implementation are out of scope for Agentic SEO skills. In compound requests, list them as non-goals or blocked external work, and continue only with the SEO deliverables that remain in scope.
- If public content depends on missing strategy, missing evidence, or unchecked content, mark the dependent deliverable blocked until the upstream gate passes.
- Preserve the requested output language. For pt-BR, keep accents in all human-facing text:
página,conteúdo,análise,evidência,aprovação,técnico,não,até. - Prefer a local browser handoff for previews, decisions, sensitive inputs, or option selection when available. Do not make terminal commands the primary UX for nontechnical decisions.
- The primary delivery is the workbench spec in the Web Companion. Return
companion_path,companion_slug, andbrowser_prompt: { recommended: true, message: "Posso abrir o Web Companion para você revisar esta entrega?", artifact_path: "project/workbench/specs/<slug>/spec.md", open_with: "project-browser" }; preserve the paths forspec.md,plan.md, andresult-check.md. Ask before opening the browser.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-driven is a skill published in the GitHub repository agencia-conversion/agentic-seo-skills (50 stars, last pushed 3mo ago), licensed MIT. It adds 83 tokens to every session and 2,467 once invoked, about $0.0004 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.
