Modifies repository's agent contract for documentation and manifests

Identifies changes in `AGENTS.md`, `docs/agent/*`, `tools/agent/*`, `tools/make/agent.mk` or CI/workflow classification.
Updates contributor-facing wrappers such as README, CONTRIBUTING, and PR template.
Validates modifications through `make agent-validate` to ensure consistency between documentation and manifests.
Ensures all surfaces (harness_docs, harness_exec, contributor_interface, ci_e2e) pass validation before finalizing changes.

description: Modifies the repository's agent contract including AGENTS.md, docs index, manifests, validation scripts, and contributor-facing harness wrappers. Use when updating agent documentation, changing repo manifests, editing validation scripts, modifying CI/workflow classification, or updating contributor-facing guides like README.md, CONTRIBUTING.md, or the PR template.

# Harness Contract Change

## Trigger

- Change `AGENTS.md`, `docs/agent/*`, `tools/agent/*`, `tools/make/agent.mk`, or harness-facing CI/workflow classification
- Change contributor-facing wrappers that explain the harness, such as `README.md`, `CONTRIBUTING.md`, or the PR template

## Required Surfaces

- `harness_docs`

## Conditional Surfaces

- `harness_exec`
- `contributor_interface`
- `ci_e2e`

## Stop Conditions

- The edit would create a second conflicting source of truth instead of updating the canonical one
- The rule change cannot be enforced or validated in the same change

## Workflow

1. Read agent README, governance docs, and execution-plan guidance for current contract state
2. Modify agent contract docs, manifests, validation scripts, or contributor wrappers
3. Run `make agent-validate` to check alignment between docs and manifests
4. Run `make agent-ci-gate CHANGED_FILES="..."` to verify all surfaces pass
5. Record any durable code/spec divergence as indexed debt entries

## Gotchas

- Do not add a prose-only harness rule when the same invariant can be enforced in manifests, scripts, or CI.
- When routing, validation, or contributor workflow changes, update the executable layer and the human-readable layer in the same patch.

## Must Read

- [docs/agent/README.md](../../../../docs/agent/README.md)
- [docs/agent/governance.md](../../../../docs/agent/governance.md)
- [docs/agent/plans/README.md](../../../../docs/agent/plans/README.md)

## Standard Commands

- `make agent-validate`
- `make agent-scorecard`
- `make agent-report ENV=cpu CHANGED_FILES="..."`
- `make agent-ci-gate CHANGED_FILES="..."`

## Acceptance

- Harness docs, manifests, scripts, and contributor wrappers remain aligned
- The change improves discoverability, source-of-truth clarity, or mechanical enforcement of the harness
- Any durable code/spec divergence discovered during the harness change is recorded in the matching indexed debt entry instead of being left only in PR text

Skill	Description
config-platform-change	Synchronizes config representations across router config, Python CLI schema, and dashboard config UI. Use when adding or changing a config concept that spans those surfaces or addressing config representation debt before Kubernetes-facing translation.
cross-stack-bugfix	Diagnoses and fixes bugs that span multiple layers (runtime, CLI, UI, platform, tests) requiring coordinated changes across surfaces. Use when a bug does not map cleanly to a narrower skill, the fix touches more than one surface, or changes need cross-cutting validation.
dashboard-platform-change	Modifies dashboard frontend or backend surfaces that present, configure, or manage router behavior through the console UI. Use when changing dashboard pages or components, backend handlers, console persistence, auth or session flows, or user-visible routing metadata in the dashboard.
fleet-sim-change	Modifies the fleet simulator package, API service, release wiring, or simulator-owned docs and assets as one maintained subsystem. Use when changing src/fleet-sim, simulator release workflow, or fleet-sim-owned docs and assets under website/.
k8s-platform-change	Modifies Kubernetes-facing operator, CRD, deployment-profile, or DSL translation behavior for semantic-router platform integration. Use when changing operator APIs or controllers, deployment stack manifests, profile-owned platform wiring, or router-to-Kubernetes translation layers.
maintainer-issue-pr-management	Manages GitHub issue and pull-request lifecycle including creation, updates, triage labelling, and closeout metadata using canonical templates and repository taxonomy. Use when a maintainer asks to create, update, close, or triage GitHub issues or PRs, or when issue creation requires codebase analysis for scope, labels, or acceptance criteria.
maintainer-release-ops	Maintainer release and milestone operating workflow. Use when a maintainer wants to plan a release, create milestone issues, sync GitHub issue or PR state, generate a daily review brief, or manage stale PRs and backlog routing.
openclaw-vsr-bridge	Install vLLM Semantic Router in agent-safe mode, import supported OpenClaw model providers into canonical VSR config, and rewrite OpenClaw to target VSR.
plugin-end-to-end	Implements end-to-end plugin changes spanning router config, post-decision processing, optional CLI/UI exposure, and E2E test coverage. Use when adding a new plugin type, changing plugin config schema or execution semantics, updating plugin chain behavior, or modifying plugin-exposed metadata across surfaces.
router-service-platform-change	Modifies router-side API, authz, memory, provider, storage, or runtime service modules outside config, decision, selection, and extproc plugin chains. Use when changing apiserver endpoints, authz or rate-limit policy code, memory or response storage flows, provider adapters, or other router service-platform modules.
