-Stop skills from trying to reach user-invoked skills through the Skill tool: fix cross-skill references that violated the "no other skill can call it" invariant in `.agents/invocation.md`, in `to-spec`, `wayfinder`, `to-tickets`, `triage`, `code-review`, and `diagnosing-bugs`.
-
-- `to-spec`, `wayfinder`, `to-tickets`, `triage`, and `code-review` each carried a precondition ("...run `/setup-matt-pocock-skills` if not") that PR #878 rewrote into a literal `Call the Skill tool with "setup-matt-pocock-skills"` instruction. `setup-matt-pocock-skills` is user-invoked, so none of these skills (user-invoked or model-invoked) can call it. Reworded all five as instructions for the agent to tell the human to run it instead.
-- `diagnosing-bugs`'s Phase 6 post-mortem hand off to `improve-codebase-architecture` (also user-invoked) the same way, from an autonomous, often-unattended bug-fixing flow with no human in the loop to catch the failed call. Removed the hand-off outright rather than softening it, since it rarely fired in practice. Phase 6 is now "Cleanup" only; the mechanical checklist is untouched.
-- Added a carve-out paragraph to `.agents/invocation.md`'s "Dependencies between them" section: the `Call the Skill tool with "name"` convention only applies when the named skill is model-invoked. This is the section PR #878 introduced without reconciling it against the user-invoked/model-invoked invariant stated eight lines above it; the gap is most of why this bug reached six call sites instead of one.

It takes a spec and its tickets and drives them to a single PR: the tickets are read as a task graph with blocking edges, so implementer subagents run in background worktrees across the ready frontier for concurrency, a merger subagent folds each one back into the PR branch, and the flow closes with `/code-review` before the PR is marked ready.

+name: implement-spec
+description: "Implement a specification in code."
+disable-model-invocation: true
+---
+
+You have been provided a spec. This spec should have tickets associated with it, describing how to implement the spec.
+
+The goal is a PR which implements the entire spec on a single branch.
+
+The tickets are not a list of steps. They are a **task graph** with blocking relationships between them. This means there is always a **frontier** of tickets which are ready to be grabbed.
+
+Communication to and from subagents should be sparse. Communicate primarily through **context pointers**: to the spec, tickets, research notes, and previous commits. Don't duplicate information already available via pointers.
+
+**Implementer subagents** should be run in the background where possible for **maximum concurrency**.
+
+## Steps
+
+1. Read the spec and tickets. Read enough to understand the task graph.
+
+2. (optional) Use an **exploration subagent** to conduct any exploration required by the tickets - relevant codebase files or external documentation. Ensure the exploration subagent can save files - it should save its markdown notes in a directory outside the repo, accessible by all future subagents. This lets **implementer subagents** focus on implementation rather than exploration.
+
+3. Create a branch, and a draft PR. The PR should be marked as 'closing' the spec issue and tickets.
+
+4. Use **implementer subagents** to implement each ticket. Each implementer subagent should work in its own worktree, on its own branch.
+
+5. Once an **implementer subagent** completes, merge its work to the PR branch with a **merger subagent**.
+
+6. If this changes the **frontier** of available tickets, kick off more **implementer subagents** to work on the new tickets. This allows for maximum concurrency.
+
+7. Once all tickets are complete, run /code-review on the PR branch. Fix all issues raised by the code review in a single **implementer subagent**.
+
+8. Mark the PR as ready for review.
+
+9. Clean up all **implementer subagent** worktrees.
