oclif-plugin-development

oclif-plugin-development is a skill for Claude Code, Codex from jterratsdev/ableton-live-mcp. It costs 0 tokens per session (961 once invoked), scanned A, original, MIT.

A guide for building Open Orchestra plugins with oclif, a framework for extending command-line applications. It covers TypeScript packages, commands, hooks, manifests, and React/Vite plugin interfaces.

In plain words
What is it for?
Use it when designing, implementing, testing, packaging, or reviewing an Open Orchestra command, hook, package, or plugin interface.
Why use it?
It helps keep command code simple while placing business rules, storage, retries, permissions, and plugin behavior in suitable services.

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 A, and why

oclif-plugin-development 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.

Oclif Plugin Development

Use this skill when a task designs, implements, tests, packages, or reviews an Open Orchestra plugin based on oclif, TypeScript, React, Vite, hooks, manifests, or CLI command extensions.

When To Load

  • Trigger: oclif
  • Trigger: plugin
  • Trigger: cli plugin
  • Trigger: command plugin
  • Trigger: hook
  • Trigger: manifest
  • Trigger: package exports
  • Trigger: npm plugin
  • Trigger: React/Vite plugin UI
  • Trigger: TypeScript plugin package

Architecture

  • Treat plugin specialization as an on-demand skill, not as a permanent role profile. Developer, Architect, QA, Security, DevOps, UX, or Tech Lead can use this skill when the task requires plugin work.
  • Keep command classes or command modules nearly logicless: parse flags/args, call one service/use-case, format output, and map expected errors to user-safe messages.
  • Put business rules, workflow policy, persistence, batching, retries, plugin discovery, and registry mutations in domain services or use-cases.
  • Define public plugin contracts before implementation: plugin id, supported host version, commands, hooks, capabilities, permissions, configuration, outputs, evidence expectations, and compatibility constraints.
  • Prefer typed registries and manifest-derived metadata over hardcoded command or hook lists. Load collection-standards when plugin work repeats commands, hooks, providers, roles, statuses, selectors, fixtures, or validators.

Oclif CLI Standards

  • Use TypeScript and typed flags/args.
  • Keep stdout, stderr, exit code, and JSON output stable and testable.
  • Provide JSON output for machine consumers when a command returns structured data.
  • Keep help, examples, aliases, deprecations, and hidden/internal command status explicit.
  • Treat hooks as integration points with clear ordering, idempotency, timeout, failure, and observability behavior.
  • Do not hide network calls, filesystem writes, shell execution, or destructive actions inside command parsing.

Changes

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.
