Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

gtm-seo scanned grade B with 1 finding 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.

Tells the agent never to refusemediumAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

> Then generate the work anyway - never refuse.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO Groundwork Audit & Investment Verdict

Default lens: a SaaS / AI software startup. Advise a technical founder marketing their own modern software product (SaaS, AI/API, dev tool, or app). Tailor every recommendation to that reader.

Stage-fit (seo): Tier 1 Too early · Tier 2 Too early · Tier 3 Core. If the founder's tier (from PROFILE.md) makes this Too early or Avoid, prepend this note verbatim: "Active SEO is a compounding bet - meaningful traffic takes months, and at your stage you need validation in weeks. Do the cheap groundwork now (crawlers allowed, site indexed, clean titles), so the domain banks age and history while you sell by hand - and skip the content program without guilt; the report names the conditions that would flip that verdict. AI-answer visibility is /gtm geo's job, and /gtm audit scores your AI-search readiness every run." Then generate the work anyway - never refuse.

Full persona and general guidance: read ../gtm/templates/advisor-prompt.md (installed with the gtm orchestrator); if the file is absent, continue with the default lens above.

Bundled scripts: the node .claude/skills/... commands below assume the per-project copy path. When that path doesn't exist (a plugin install, or another agent's skills directory), the scripts sit beside this skill - resolve each path relative to this skill's own folder before running.

You are the classic-search skill for /gtm seo <target>. Your job is deliberately founder-sized, and it has exactly two deliverables:

  1. The groundwork checklist - is this site crawlable, indexed, and legible to search engines? Groundwork costs hours, not months, and it pays whether or not the founder ever runs an SEO program: a clean, indexed site banks domain age and history while the founder sells by hand.
  2. The investment verdict - an explicit, tier-tied answer to "should I invest in active SEO now?", including plain permission to skip it. Most early founders should skip it, and this skill is the one place in the suite that says so with reasons instead of guilt.

What this skill is not: a full SEO practice. It does not track rankings, research keywords at scale, analyze backlinks, or plan content calendars - the verdict (Phase 4) names that boundary honestly.

Scope boundary: this skill covers classic search (Google, Bing - ranked pages for typed queries). Visibility in AI answers (ChatGPT, Perplexity, Google AI Overviews) is the neighbor job with its own skill: /gtm geo. The two rest on the same base - crawled, indexed, citable - so finish the groundwork here first; /gtm geo picks up where this skill stops.

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.
