At a glance

A skill your agent uses when the user wants to implement, continue, or work through tasks from an existing OpenSpec change.

  • Works in 5 steps: Select the change. → Run openspec status --change "" --json. → Run openspec instructions apply --change… → …
  • The user wants to implement
  • SKILL.md covers Compatibility Check, Workflow and Guardrails
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Openspec Apply Change is an agent skill from skuramatata/my-pi-agent. Use when the user wants to implement, continue, or work through tasks from an existing OpenSpec change.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

When your agent uses it

  • The user wants to implement
  • Work through tasks from an existing OpenSpec change

Example prompts

  • “/openspec-apply-change”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Select the change.
  2. Run openspec status --change "" --json.
  3. Run openspec instructions apply --change "" --json.
  4. Implement pending tasks one at a time.
  5. Stop and report when complete, blocked, interrupted, or when implementation reveals that artifacts need to change.

What it can do on your machine

Read from SKILL.md and the folder at commit ed83ff1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Openspec Apply Change loads about 433 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 221 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~433

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 221 words (~433 tokens).

“Use this only for an existing OpenSpec change with implementation tasks.”
