apply

A command for applying an approved OpenSpec change. OpenSpec is a project format for describing a proposed change, its design, and its implementation tasks.

In plain words
What is it for?
Use it to read an OpenSpec proposal, implement its tasks in order, verify the result, and mark the finished tasks accurately.
Why use it?
It keeps implementation focused on the approved scope and synchronizes the task checklist with the work that was actually completed.

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

apply 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.

Origin

This is a copy

100% identical to OpenSpec: Apply — 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


name: OpenSpec: Apply description: Implement an approved OpenSpec change and keep tasks in sync. category: OpenSpec tags: [openspec, apply]

Guardrails

  • Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.
  • Keep changes tightly scoped to the requested outcome.
  • Refer to openspec/AGENTS.md (located inside the openspec/ directory—run ls openspec or openspec update if you don't see it) if you need additional OpenSpec conventions or clarifications.

Steps Track these steps as TODOs and complete them one by one.

  1. Read changes/<id>/proposal.md, design.md (if present), and tasks.md to confirm scope and acceptance criteria.
  2. Work through tasks sequentially, keeping edits minimal and focused on the requested change.
  3. Confirm completion before updating statuses—make sure every item in tasks.md is finished.
  4. Update the checklist after all work is done so each task is marked - [x] and reflects reality.
  5. Reference openspec list or openspec show <item> when additional context is required.

Reference

  • Use openspec show <id> --json --deltas-only if you need additional context from the proposal while implementing.

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.
