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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 336 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00097 | $0.04648 |
| Opus 5.5 | $0.00039 | $0.01859 |
| Sonnet 5.5 | $0.00019 | $0.00930 |
| Haiku 4.5 | $0.00010 | $0.00465 |
Grade A, and why
positioning-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 12d 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 — 466 lines — stays where its author put it; the contents beside it link to each section on GitHub.
positioning-messaging
Built on Dunford's Obviously Awesome framework. Delivers sharp, defensible positioning through a 6-phase discovery and stress-test process.
Onboarding
Run once at the start of every new session, before any discovery. One question at a time, no output until it is complete. Read references/onboarding.md and follow its five steps: check the brain, select the mode, confirm the persona, confirm the alternatives (3 minimum), and parse any attached images. Then state the session setup back in one paragraph and wait for confirmation before Phase 1.
A missing brain never stops this skill. Say once: "No brain found, so output will be less precise. Run product-marketing-context (a separate plugin) for sharper results. Continuing."
Trigger
-
When: Positioning, messaging, value prop, sales copy, competitive messaging, homepage copy, messaging audit, or any request involving how a product should be described to buyers
-
Not for: Product specification → use
prd. Building the ICP itself — demographics, behaviors, JTBD, needs — before positioning work →ideal-customer-profile, run first if Section 2 is still firmographic-only. Mapping the buying committee or building persona cards →buyer-personas, run first for a real primary-persona pick instead of guessing. The "why now" narrative →market-context, run first if Section 5 is thin. How the brand should sound →brand-voice, run first if Section 4 is thin. -
Example prompts:
- "Build positioning for [product]"
- "Our messaging sounds like everyone else"
- "Help me position against [competitor]"
- "Write our homepage headline and pillars"
- "Audit this messaging for coherence"
- "We can't explain what we do to sales"
- "Is this positioning working?"
Inputs
- Args: Product/market context, target persona (required), alternatives (3+ minimum, must include status quo + do-nothing), customer evidence or win/loss signals
What ships with it
2 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-messaging is a skill published in the GitHub repository stefanoskarakasis/Product-Marketing-Skills (8 stars, last pushed 4d ago), licensed MIT. It adds 97 tokens to every session and 4,648 once invoked, about $0.0004 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 2026-08-31.
Other skills, from other repositories
report
A way to export a chat card or reply as a standalone HTML report, meaning a file that can open in a browser without the chat application. It preserves the card template, including right-to-left Persian or left-to-right English layouts.
k8s-rightsize
Right-size Kubernetes CPU and memory requests from Prometheus usage (p95 CPU, p98 memory over 7 days), size the node count, tune KEDA autoscaling. Use when asked to rightsize workloads, cut node cost, or "how many nodes do we need".
owasp-security
Deep OWASP reference: Top 10 2025, ASVS 5.0, secure patterns, per-language quirks, LLM Top 10 and agentic AI security. Use for an in-depth security review, auth work, or hardening an LLM or agent app. For the everyday baseline use secure-coding.
fig
One self-contained HTML file holding a looping animated SVG, for ideas that move: flows, loops, retries, queues, fan-outs. Use when the user says "fig" or a diagram would be better animated.
brand
A project-specific visual identity for chat cards and saved reports, using the project's colors, logo, and fonts. It finds these details in the repository or asks the user for them, then stores the result in a committable `.readable/` folder.
workspace-rules
A set of guidelines for deciding which rules belong in a repository's workspace instructions and which should be enforced by its build or checks.
