Version check first. Before running any other command, run go run . version check.

• On status: "match", continue with the skill and produce no version-related output.
• On "mismatch" or "missing", the installed Spektacular files are out of date: relay the response's action message to the user, ask them to re-run go run . init <agent>, and wait for their decision before continuing.
• Never modify or re-install any installed files yourself — refreshing the installation is always an explicit, user-initiated re-run of init.

STOP. Read this before running any command below. A single successful CLI call — including the very first implement new — is NOT task completion. It is not a milestone to report back to the user. It is one step out of many in a workflow that you must keep driving, turn after turn, without stopping, until the CLI itself tells you the workflow is finished. If you find yourself about to say "successfully completed" or summarize results after calling implement new or implement goto even once, you are wrong — go back and read the instruction field you just received, do what it says, and call goto again.

What this skill does

This skill drives a multi-step interactive workflow that executes an approved plan held in the plan store, producing working code, tests, and a changelog. The workflow is owned by the go run . CLI, not by you — the CLI is the state machine and you are the executor, and the CLI (not the filesystem) is how you reach every plan document.

On each turn, the CLI returns JSON containing an instruction field. That instruction describes exactly one step (e.g. analyze, implement a phase, verify, update changelog, write the test plan, …). You must:

1. Read the instruction carefully.
2. Perform the step — this may mean reading the plan, spawning subagents, editing code, running tests, or writing to the changelog.
3. When the step is complete, run the goto command named at the bottom of the instruction to advance the state machine.
4. Read the next instruction from the new JSON response and repeat.

This is a loop. Do not stop after the first step. Keep looping — step → goto → next instruction → step — until a returned instruction tells you the workflow is finished. Only then should you report completion to the user.

Concretely: do not stop after implement new. That command only starts the workflow — it returns the first instruction, not a finished implementation. Seeing a clean JSON response with no error is not a signal to stop; it is the signal to keep going. Reporting success, summarizing "implementation initialized," or handing control back to the user at this point is the single most common way this skill is executed incorrectly — do not do it.
