Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Spec-driven coding workflow for coderX agents. Use this skill whenever implementing, fixing, refactoring, or iterating code from hybrid docs or specified requirements, especially when file index, knowledge index, or evaluator findings are present.Key capabilities
- →Read specifications and acceptance criteria
- →Read engineering file index and knowledge index
- →Fix issues based on audit reports
- →Implement code changes based on execution brief
- →Verify code changes against acceptance criteria
- →Output verifiable code changes
How it works
This skill executes development by first reading specifications and acceptance criteria, then consulting engineering documents and knowledge graphs. It prioritizes audit feedback and implements changes verifiable against declared criteria.
Inputs & outputs
When to use specX
- →Implement feature spec
- →Refactor based on audit
- →Iterate from requirements
About this skill
specX
Use only when coderX is dispatched by xdel or xflow with a Hybrid Tree task.
Before Editing
- Read the dispatch task first.
- Read the assigned Child acceptance criteria and file scope.
- Read only the Parent sections required for ownership, dependencies, or global constraints.
- Treat the dispatch interpretation and Child acceptance criteria as authoritative. Stop on contradictions instead of guessing.
During Implementation
- Follow
engineeringXfor implementation principles and self-review. - Stay within the assigned Child scope. Report required shared-file or scope changes to the Main Agent.
- Do not write to Parent or Child documents.
- Expand context only when a named dependency or API contract requires it.
Completion
- Perform the
engineeringXself-review. - Run relevant checks when available and report what was actually run.
- Return the mode-specific implementation summary or Bus Payload requested by the dispatch contract.
When not to use it
- →When the Type 0 Dispatch Payload is missing Parent or Child paths
- →When the execution brief conflicts with current files or Child AC
- →When there is no active reference and no document record in context for non-xunit tasks
Limitations
- →Does not write to any document directly
- →Must not skip specification reading and directly code
- →Must not ignore the `Context Manifest`
How it compares
This skill enforces a spec-driven workflow by requiring explicit requirement alignment and context-oriented loading before implementation, ensuring changes are verifiable against acceptance criteria, unlike direct coding.
