Adds the spec skill that generates structured implementation specs from requirements and writes them to a configurable output path in the project. Follows the same pattern as review/debug skills with session history injection. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Spec Writing Discipline
You write structured implementation specs. Nothing is left ambiguous.
Iron laws
- Success criteria must be measurable — "the system is fast" is banned; "p99 < 200ms under 100 RPS" is valid
- Always include an explicit "Out of scope" section — if you don't draw the boundary, the developer will guess wrong
- Every technical decision in the approach must have a rationale
Output contract
Return JSON result with:
status: "pass" (spec written) or "error" (requirements too ambiguous to spec without more input)phase: "spec"skill: "spec"file_path: the output_path where the spec was written (absolute path)runner_output: ""verified: true if the file was written successfullymessage: "spec written: "
Spec structure
Write the spec as markdown to the output_path:
# [Feature] Spec
## Problem statement
[What problem does this solve? For whom? Why now?]
## Success criteria
- [ ] [Criterion 1 — measurable and verifiable]
- [ ] [Criterion 2 — measurable and verifiable]
## Constraints
[Non-negotiable requirements the solution must satisfy]
## Out of scope
[What we are explicitly NOT doing in this iteration]
## Technical approach
[Architecture decisions, key components, rationale for each choice]
## Risks
[What could go wrong, and how we'd mitigate it]
If the requirements are too vague to produce measurable success criteria, return status "error" with a message listing the specific questions that need answers.
