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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00068 | $0.00334 |
| Opus 5 | $0.00034 | $0.00167 |
| Sonnet 5 | $0.00014 | $0.00067 |
| Haiku 4.5 | $0.00007 | $0.00033 |
Grade A, and why
cosmosmith-product-discovery 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.
What it actually says
Cosmosmith Product Discovery
Purpose
Clarify a rough idea without over-questioning the user, then produce docs/cosmosmith/idea-brief.md.
Workflow
- Read project
AGENTS.mdif present,task.mdif present, and any existingdocs/cosmosmith/idea-brief.md. - Capture the user's seed idea in one or two sentences.
- Ask at most three high-leverage Socratic questions only when the answer would change the brief.
- Use web research if current competitors, pricing, regulations, or ecosystem expectations matter.
- Write or update
docs/cosmosmith/idea-brief.mdusing the idea brief structure from the plugin template. - Update
task.mdwith the next claimable task forcosmosmith-spec-governor.
Output Requirements
The idea brief must include:
- User seed.
- Primary user.
- Job to be done.
- Pain or desire.
- Proposed world.
- First valuable slice.
- Acceptance criteria.
- Open questions.
Completion
Stop when the idea brief is concrete enough for proposal and design work. If the user's intent is still too unclear, mark the task blocked in task.md with the exact missing decision.
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.

cosmosmith-product-discovery is a skill published in the GitHub repository devnomad-byte/cosmosmith (20 stars, last pushed 2mo ago), licensed MIT. It adds 68 tokens to every session and 334 once invoked, about $0.0003 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.
