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 | $0.00002 | $0.00018 |
| Opus 5 | $0.00001 | $0.00009 |
| Sonnet 5 | $0.00000 | $0.00004 |
| Haiku 4.5 | $0.00000 | $0.00002 |
Grade A, and why
missing-description 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 yesterday.
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.
This is a copy
100% identical to missing-description — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Missing Description
This skill has no description field.
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.

missing-description is a skill published in the GitHub repository rokoss21/iosm-cli (146 stars, last pushed 4mo ago), licensed MIT. It adds 2 tokens to every session and 18 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to missing-description, differing in 0 lines, and is treated as a copy.

manta-pr-workflow
The standard implementer workflow for MANTA (Better UI) agents — checkout, branch, implement, typecheck + test, push, draft PR, verification results template, reassign to reviewer. Plus the 50-turn self-policed budget cap. Load this when you're about to take action on an assigned implementer issue.
manta-e2e-smoke
Drive MANTA's built Electron app in a real renderer context (Playwright's electron launcher) and assert that key UI surfaces render correctly — no crash, no blank screen, sidebar/chat/terminal present. Load BEFORE marking any frontend/UI task done, and when manta-pr-workflow or manta-handle-reviewer-return verifies a…
manta-handle-reviewer-return
Protocol for MANTA implementer agents when reviewer reassigns an issue back. Distinguishes Block (fix-here) vs Block (followup-issue) and handles Question resolutions. Load this when an issue you previously sent to reviewer comes back to you with status todo.
verify-build-manta
Runs npm run typecheck && npm test. Mandatory before marking any task done.
manta-token-economy
Token-economy discipline for MANTA agents on OpenCode runtime — batch parallel tool calls, compound shell commands, avoid re-reading after Edit, use offset/limit on large files. Load this if a task touches a long file or you find yourself making many sequential tool calls.
manta-live-session
Talk to a real manta box from an agent session — create a chat session, send a prompt, read the reply, and mint a pairing code for a phone or Simulator. Use whenever a task needs live box data rather than a unit test. Always runs on voska/default.
