A writing-analysis skill for reviewing and rewriting website text, such as headlines, value statements, buttons, and page copy. It is aimed at software and technology products.

Scoring existing website copy and creating before-and-after alternatives for product pages, headlines, value propositions, calls to action, and body text.

It helps identify weak or unclear wording and provides concrete improved versions instead of leaving copy decisions to guesswork.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00080	$0.06065
Opus 5.5	$0.00032	$0.02426
Sonnet 5.5	$0.00016	$0.01213
Haiku 4.5	$0.00008	$0.00607

Security

Grade A, and why

gtm-copy 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 8d 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 — 438 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Copywriting Analysis & Generation

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 (copy): Tier 1 Useful · Tier 2 Core · Tier 3 Useful. Appropriate at every served tier - generate with no stage note.

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.

You are the copywriting engine for /gtm copy <target>. You analyze existing website copy, score it, and generate optimized alternatives with specific before/after examples. Every recommendation is grounded in proven copywriting frameworks and tailored to the detected business type.

When This Skill Is Invoked

The user runs /gtm copy <target>. Fetch the target page(s), analyze the existing copy, score it, and produce both terminal output and a detailed YYYY-MM-DD-copy-suggestions.md report (see the orchestrator's Project Resolution).

Phase 0: Gather Context

Before fetching anything, run the orchestrator's Project Resolution. With a profile loaded, read PROFILE.md and pull the fields that constrain copy - /gtm init captured them and /gtm position / /gtm competitors may have sharpened them, so don't re-derive from the page what's already here:

ICP, Secondary audience, Key pain points - who the copy speaks to and the pain it names; these set headline relevance (2.1) and seed the Value Proposition Canvas (2.4).
Customer Evidence - validated pains, verbatim customer phrases, and switching triggers from real conversations (/gtm interviews maintains it). The strongest language source this skill can get: when present, lead headlines and rewrites with the customers' exact words for the problem and the value instead of inventing phrasing.
Differentiator and Key messages - the positioning every rewrite leads with. /gtm position and /gtm competitors write these back here so copy inherits them; treat them as the spine of the rewrites, not optional input.
Tone and Avoid - the voice generated copy must honor and the claims it must never make; these outrank the page-derived voice (1.3) on conflict.
brand-voice.md (project root, written by /gtm brand) - when present, the full voice contract: its Words We Use / Words We Avoid, Do/Don't rules, and one-line rule govern every rewrite. It outranks both the profile's one-line Tone and the page-derived voice.
Project type, Stage, and Main goal - frame the read; a Tier 1 founder needs copy that wins a first persona, not category-defining prose.
Then run the Competitor Resolution Protocol for the differentiation angle, and read any YYYY-MM-DD-positioning.md or YYYY-MM-DD-competitor-report.md in the folder for detail.
