oh-my-pi

oh-my-pi is a skill for Claude Code from amirkiarafiei/subagent-cli-skills. It costs 88 tokens per session (2,392 once invoked), scanned C, original, MIT.

A skill for handing large, multi-step coding work to the Oh My Pi command-line tool in a separate session. It passes the main task, decisions, scope, and limits so that session can work independently.

In plain words
What is it for?
Use it for multi-file changes, broad refactoring, repository exploration, batch edits, and other long tasks. It can stop after a time limit, emit machine-readable progress, and use different approval levels for actions.
Why use it?
It keeps long tasks out of the main conversation and supports unattended work with time and approval boundaries. The documentation is not verified against an installed tool, so its commands should be checked first.

Token cost

What it costs to keep this loaded

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.

Security

Grade C, and why

oh-my-pi scanned grade C with 1 finding 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 3d 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.

Oh My Pi CLI (subagent/task delegation)

Documented, not verified. Written from Oh My Pi's own docs source on 2026-09-06 and not checked against an installed binary. Before trusting any flag here, run omp --help; on a mismatch use what the binary actually offers and tell the user which line in this file is wrong.

Use Oh My Pi (omp) to run a separate long-horizon pass over the repo: multi-step implementation, broad refactors, batch file writes, or deep exploration—similar to handing a task to a subagent. You stay orchestrator: smaller prompts, less context burn.

When to use Oh My Pi

  • Large or multi-step work: several files, phases, or checkpoints (feature slice, migration, test suite, docs sweep).
  • Time-bounded delegation: --max-time <duration> is a real wall-clock limit (600, 10m, 1h) — the only one among the CLIs in this repo, and the reason omp is a good fit for unattended runs.
  • Machine-readable progress: --mode json emits a structured event stream for headless consumption.
  • Fine-grained approval control: a documented three-level approval model (always-ask / write / yolo) rather than one all-or-nothing switch.
  • Session portability: --from-claude / --from-codex import an existing Claude Code or Codex session.
  • User explicitly asks for Oh My Pi or "use omp for this."

When not to use

  • Small / single-step tasks answerable with one or two edits or a short explanation.
  • Tight feedback loops where the user wants rapid back-and-forth refinement in one thread.
  • Secrets or policy-sensitive flows—avoid piping credentials; redact before delegating.
  • Already-loaded context where duplicating the whole plan adds no value—handle locally.
  • Low ROI (Return on Investment): if the task requires high precision over a single line, or composing the Handoff Table costs more than editing the file yourself.

Delegation and context (critical)

Isolated subagent context saves tokens but splits the story: omp does not see the main session's full thread. Poor handoffs cause misread subtasks, conflicting assumptions (stack, style, APIs), and wasted edits.

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.

oh-my-pi is a skill published in the GitHub repository amirkiarafiei/subagent-cli-skills (5 stars, last pushed 4d ago), licensed MIT. It adds 88 tokens to every session and 2,392 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-08.
