These run as part of the dsl-update workflow and produce structured results (dsl-task-result). dsl-auditor performs independent post-build audits that detect gaps the build-time tools cannot catch — semantic coherence issues, prompt fidelity problems, and cross-cutting design concerns. **Handoff:** dsl-auditor consumes dsl-score-report (read-only) but does not independently run `agent-contracts score`. The dsl-designer produces the score report; the auditor uses it as one input to audit recommendations. **Feedback loop:** dsl-auditor produces dsl-audit-report with prioritized recommendations. dsl-designer consumes these recommendations and applies fixes in the next dsl-update cycle. - title: "agent-contracts DSL Specification Reference" content: | ### Top-Level Structure ```yaml version: 1 # Required.

title: "Merge Operator Reference" content: | Override base DSL inherited via extends using the following merge operators: | Operator | Behavior | Target | |----------|----------|--------| | `$append` | Append to end | map / array | | `$prepend` | Prepend to start | map / array | | `$insert_after` | Insert after specified element | array (identified by id field) | | `$replace` | Replace entire value | any | | `$remove` | Remove by key/ID | map / array | | direct value | Override scalar field | scalar | Maps (agents, tasks, etc.) are automatically deep-merged. Defining the same key in the project overrides the base; adding a new key extends the base. Arrays (responsibilities, constraints, etc.) are replaced by default in the project. Use `$append` / `$prepend` to add to the base array.
