Config Authoring

Dispatcher Config Authoring (AMS)

Design minimal, deterministic changes for the Adobe Dispatcher Apache HTTP Server module and related HTTPD configuration in AEM 6.5/AMS, then verify with MCP evidence.

Variant Scope

• This skill is AMS-only.
• Scope is fixed by this skill directory; do not ask the user to choose deployment variant.

MCP Tool Contract

Use only these Dispatcher MCP tools:

• validate
• lint
• sdk
• trace_request
• inspect_cache
• monitor_metrics
• tail_logs

Workflow

AMS Config Progress
- [ ] 1) Confirm scope and acceptance criteria; if the repo layout is unclear, normalize it with `repo-layout-workflows.md`
- [ ] 2) Apply AMS 6.5 guardrails for tier routing, variables, flush ACL, and immutable boundaries
- [ ] 3) Decompose target URLs (path/selectors/extension/suffix) and use that model for all URL-based rules—filters, cache rules, etc.—using `/path`, `/selectors`, `/extension`, `/suffix` or aligned globs (not raw `/url`) where applicable; then design complete section-level edits
- [ ] 4) Update config with least-privilege defaults (produce final merged section, not isolated rule snippets)
- [ ] 5) Run static checks: validate -> lint (deep/order-aware when filters changed)
- [ ] 6) Run SDK checks: `sdk({"action":"check-files","config_path":"<dispatcher src path>"})`, `sdk({"action":"diff-baseline","config_path":"<dispatcher src path>"})` as needed
- [ ] 7) Run runtime verification in host-path/log environment
- [ ] 8) Return diff, evidence table, risk/rollback, and citations

Verification Scope Selection

Use the shared references to select the minimum evidence set:

• mode-specific-verification-matrix.md
• test-case-catalog.md

Output Contract

Always include:

• files changed + intent
• exact insertion location and final merged section content for each edited block
• checks executed + evidence
• selected test IDs
• risk/rollback plan
• residual risks and next checks

Feature cross-boundary (Playbook G: auth_checker)

Permission-sensitive caching (/auth_checker) is end-to-end: it requires both Dispatcher config and an AEM servlet. When implementing Playbook G from scratch, create or verify the auth-check servlet in the project core bundle (path /bin/permissioncheck, HEAD/GET, 200 or 403) and allowlist it on publish; then add the /auth_checker block, filter allow for the endpoint, and /allowAuthorized "1" in /cache. See config-scenario-playbooks.md Playbook G and reference-snippets.md.

Guardrails

• Do not weaken deny-by-default security posture without explicit user approval.
• Do not claim runtime verification if host-path/log prerequisites were missing.
• Keep changes minimal and scoped.
