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 | $0.00051 | $0.00277 |
| Opus 5 | $0.00026 | $0.00138 |
| Sonnet 5 | $0.00010 | $0.00055 |
| Haiku 4.5 | $0.00005 | $0.00028 |
Grade A, and why
cosmosmith-architect 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 4d 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 Architect
Purpose
Convert product intent into a small, buildable, evolvable technical design.
Workflow
- Read
proposal.md,design.md,task.md, and relevant code. - Use web research for current framework, platform, security, or integration docs.
- Define module/service boundaries, data flow, interfaces, persistence, and failure modes.
- Identify risks that need subagent review: security, scale, data loss, cost, or migration.
- Update the architecture section of
design.mdor writedocs/cosmosmith/architecture.md. - Publish or update frontend, backend, QA, and DevOps tasks in
task.md.
Standards
- Prefer boring, proven technology unless novelty is part of the product value.
- Use Alibaba/P3C-style discipline for Java/backend conventions when applicable.
- Use OWASP-style thinking for web security.
- Keep deployability and observability in the design from the start.
Completion
Stop when implementers have clear boundaries, interfaces, risks, and verification hooks.
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-architect is a skill published in the GitHub repository devnomad-byte/cosmosmith (20 stars, last pushed 2mo ago), licensed MIT. It adds 51 tokens to every session and 277 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.
