oh-my-opencode-slim is a plugin that coordinates multiple specialized AI agents inside OpenCode, assigning codebase exploration, documentation research, architecture review, design, and implementation to different agents. It is for developers who want agent teams to divide and reconcile software-development work while mixing models from different providers. The catalogue entries are the plugin’s bundled agents, skills, and instruction.
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 | $0.00010 | $0.00325 |
| Opus 5 | $0.00005 | $0.00162 |
| Sonnet 5 | $0.00002 | $0.00065 |
| Haiku 4.5 | $0.00001 | $0.00032 |
Grade A, and why
loop-engineering 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 5d 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
Loop Engineering Skill
Grill (orchestrator interview)
- Goal: "What are you trying to accomplish?"
- Success criteria: "Describe how we know the loop succeeded."
- Success type: choose from
test,build,lint,command,fileExists,oracle,observer,manual. For CLI steps providesuccessCommand; for file detection providesuccessPath. - Execute agent: fixer / designer / explorer / librarian
- Verify agent: oracle / observer / test
- Max attempts (default 3)
- Optional context files: which files or directories should be read before execution?
Loop Monitor
- Listen to callbacks:
onLoopComplete(loopID, success)→ report final outcomeonEscalated(loopID, reason)→ escalate to humanonManualReview(loopID, reason)→ prompt human to approve/fail and callresolveManualReview(loopID, passed, reason)
- Show current state and attempt count on each callback
- For manual verification, present the failure reason before asking for pass/fail
- If human forces cancellation, call
cancel(loopID)through the orchestrator
Notes
- Manual verification is the minimal on-ramp (autoresearch pattern). It pauses the loop until
resolveManualReviewis called. Do not auto-resolve. - BackgroundJobBoard signals (totalErrors, timeoutCount) are already baked into the runtime.
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.

loop-engineering is a skill published in the GitHub repository alvinunreal/oh-my-opencode-slim (8,600 stars, last pushed 2d ago), licensed MIT. It adds 10 tokens to every session and 325 once invoked, about $0.0001 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.

Use when a task is too large for turn-by-turn orchestration and should run through the big-task workflow lane: system-wide changes, large migrations, repo-wide audits, high-confidence verification, or tasks explicitly asking to run a workflow.
