# SpecRail Implement Use this skill for the `implement` route. ## Steps 1. Read the linked issue, product spec, tech spec, and task plan. 2. Run the implementation route gate when available: ```sh python3 checks/route_gate.py --repo . --route implement --issue <issue-number> --state ready_to_implement --json ``` 3. If the gate returns `needs_human` or `blocked`, stop and report the missing evidence or gate. 4. Implement only the scoped tasks. Search before adding files, workflows, schemas, templates, policies, or public APIs. 5. Keep machine-facing IDs in English and human-facing text in the selected locale. 6. Run focused verification for touched behavior, then run the pack check when workflow assets changed: ```sh python3 checks/check_workflow.py --repo . ``` 7. Record changed files, commands, results, and remaining human gates. ## Boundaries - Do not provide final approval. - Do not merge without explicit human authorization and a passing PR gate. - Do not publish secrets or private security details. - Do not weaken tests or deterministic checks to make implementation pass. ## When to Activate - Activate this route only when the request matches the skill description and the SpecRail router selected it. - Use it after loading repository instructions, workflow policy, and the current user-authorized scope. ## Red Flags - Required issue, spec, PR, runtime, or review evidence is missing or stale. - A proposed action would bypass an offline gate, CI, re...
