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 | $0.00170 | $0.03889 |
| Opus 5.5 | $0.00068 | $0.01556 |
| Sonnet 5.5 | $0.00034 | $0.00778 |
| Haiku 4.5 | $0.00017 | $0.00389 |
Grade A, and why
positioning-and-messaging 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 19d 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 — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Positioning and Messaging
Positioning is a decision. Messaging is the expression of that decision. Most bad messaging is not a writing problem — it is an undecided or unevidenced positioning problem being papered over with adjectives.
This skill runs a four-stage sequence drawn from four practitioners, each covering the others' blind spots. Run them in order. The order is the method.
The sequence
| Stage | Question | Source | Output |
|---|---|---|---|
| 0. Evidence | Why did people actually switch — and what stopped the ones who didn't? | Bob Moesta | Demand brief |
| 1. Decision | Where do we compete, and what can only we claim? | April Dunford | Positioning decision |
| 2. Expression | Can a stranger tell what this is in five seconds? | Fletch PMM | Messaging and homepage copy |
| 3. Narrative | What changed in the world that makes this urgent? | Andy Raskin | Strategic narrative |
Why this order matters. Narrative is the most enjoyable stage and the most dangerous starting point. A team that begins with the story invents a world, names a category, and writes a manifesto — and then discovers none of it maps to a real buyer, a real shortlist, or a real reason anyone switched. That team ends up with several competing heroes and no differentiation that survives a competitor's feature page. Evidence constrains the decision; the decision constrains the words; the words constrain the story. Each stage should feel like it narrows options, not opens them.
Announce which stage you are in and what would have to be true to move on. If the user wants to jump ahead, say what is being skipped and what risk that carries, then do what they ask. The sequence is a default, not a cage.
The deliverable
All four stages feed one artifact: the Messaging Framework document. Read references/framework-document.md for the full annotated outline, and read it early — knowing what the document needs makes each stage collect the right things rather than requiring a second pass.
What ships with it
7 files 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.

positioning-and-messaging is a skill published in the GitHub repository swan-gtm/gtm-skills (181 stars, last pushed 2d ago), licensed MIT. It adds 170 tokens to every session and 3,889 once invoked, about $0.0007 per session on Opus 5.5. 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 2026-09-28.
