Oh My Claude Code is a multi-agent orchestration system for Claude Code, coordinating specialized agents, commands, skills, hooks, and workflows. It is designed for developers who want Claude Code to handle coding tasks through coordinated agent roles. Catalogue entries are components of its Claude Code workflow, including agents, commands, skills, hooks, instructions, MCP configuration, and a plugin.
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 | $0.00042 | $0.00637 |
| Opus 5.5 | $0.00017 | $0.00255 |
| Sonnet 5.5 | $0.00008 | $0.00127 |
| Haiku 4.5 | $0.00004 | $0.00064 |
Grade A, and why
maintain-verification-skill 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 today.
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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Maintain Verification Skill
A verification skill that names dead commands is worse than none: it fails
loudly on trivia and passes quietly on what matters. This skill re-syncs the
project's verify skill to the repo's current reality.
When to use
- verification errors on a command that no longer exists or was renamed
- a new surface (package, app, e2e suite) has no check recorded
- after a toolchain or CI migration
Workflow
- Audit the recorded skill: list every command and manual check it names; for each, does the command still exist and still mean the same thing (flags, scripts, config)?
- Re-run, don't re-read: execute each surviving command and compare the observed outcome to the recorded expectation. A command whose passing shape changed gets its expectation rewritten, with the new evidence.
- Find uncovered surface: what does the repo build/check now that the feature map does not mention? Add the check by running it, or record the gap as uncovered — the map stays honest.
- Update the skill and feature map in place: same file, corrected commands, corrected coverage table, dated revision line at the top.
- Record the resync through the ledger's locked writer —
appendLedgerEntryanddefaultLedgerPathfrom the installed package'sdist/features/verification-ledger/index.js(babysit's ledger step demonstrates the exact invocation); never append raw rows to.omc/state/verification-ledger.tsv— the writer owns header creation, locking, and cell sanitization. The verdict is the one the rerun actually earned —unit-test-verifiedwhen the test suite ran,live-ui-verifiedfor a live-UI flow,type-check-onlywhen only build/lint/typecheck commands were rerun — and those commands as evidence. Never claim a test ran that did not.
Rules
- The rerun is the resync; nothing is marked current without execution.
- Coverage that shrank is reported out loud, not silently dropped from the map.
- If the project's verification has outgrown the single skill shape (multi- package, per-app checks), say so and split per surface rather than fattening one file.
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.

maintain-verification-skill is a skill published in the GitHub repository Yeachan-Heo/oh-my-claudecode (40,685 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 637 once invoked, about $0.0002 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 2026-11-08.
