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 | $0.00056 | $0.00312 |
| Opus 5 | $0.00028 | $0.00156 |
| Sonnet 5 | $0.00011 | $0.00062 |
| Haiku 4.5 | $0.00006 | $0.00031 |
Grade A, and why
cosmosmith-spec-governor 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 Spec Governor
Purpose
Turn clarified intent into executable project structure: proposal.md, design.md, and task.md.
Workflow
- Read project
AGENTS.md,docs/cosmosmith/idea-brief.md, optionaldocs/cosmosmith/research-brief.md, and existing specs. - Draft
proposal.mdfrom the plugin proposal template. - Draft
design.mdfrom the plugin design template. - Create or update
task.mdfrom the plugin task ledger template. - Publish the smallest claimable tasks that can produce reviewable evidence.
- Assign owner roles, dependencies, acceptance checks, and harness notes.
- Add a governance review task for
cosmosmith-governance-review.
Task Publishing Rules
- Derive tasks from proposal and design artifacts.
- Keep each task small enough to verify.
- Use role owners, not named people, unless the user explicitly named someone.
- Leave tasks
queueduntil an agent claims them. - Never mark tasks
donewithout evidence.
Completion
Stop when proposal, design, and task ledger exist and each claimable task has output, acceptance checks, harness, loop, and dependencies.
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-spec-governor is a skill published in the GitHub repository devnomad-byte/cosmosmith (20 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 312 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.
