performance-tuning
Optimize performance of the Adobe Dispatcher Apache HTTP Server module and related HTTPD configuration for AEM 6.5 / AMS workflows only, with AMS-specific baseline and runtime verification.
What this skill does
# Dispatcher Performance Tuning (AMS) Improve cache efficiency, latency, and throughput for AMS deployments that use the Adobe Dispatcher Apache HTTP Server module and related HTTPD configuration. ## 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 1. Capture baseline metrics and cache evidence. 2. Apply AMS 6.5 guardrails (tier boundaries, variable-driven config, flush ACL safety) to candidate optimizations. 3. Prioritize low-risk/high-impact changes. 4. Apply minimal edits. 5. Verify with `validate`, `lint`, and `sdk`. 6. Compare before/after runtime evidence. ## Verification Scope Selection Use shared references to select optimization evidence depth: - [mode-specific-verification-matrix.md](./references/dispatcher-foundation/mode-specific-verification-matrix.md) - [test-case-catalog.md](./references/dispatcher-foundation/test-case-catalog.md) ## Output Contract Always return: - baseline metrics snapshot - prioritized optimization list with impact/risk - changed files and intent - executed checks + before/after evidence - selected test IDs and outcomes - rollback plan and open risks ## Guardrails - Do not claim improvement without measurable comparison. - Keep high-risk tuning opt-in unless user explicitly requests it. - Keep AMS assumptions explicit for each recommendation batch. ## References - [optimization-patterns.md](./references/performance-tuning/optimization-patterns.md) - [performance-scenario-playbooks.md](./references/performance-tuning/performance-scenario-playbooks.md) – scenario-driven tuning flows adapted from broader MCP prompt surfaces - [load-testing-guidance.md](./references/performance-tuning/load-testing-guidance.md) - [performance-monitoring-setup.md](./references/performance-tuning/performance-monitoring-setup.md) - [quick-start-execution-path.md](./references/dispatcher-foundation/quick-start-execution-path.md) – fast entry path for optimization requests - [repo-layout-workflows.md](./references/dispatcher-foundation/repo-layout-workflows.md) – map performance findings to cache, farm, vhost, rewrite, and variable file families - [playbook-command-linkage.md](./references/dispatcher-foundation/playbook-command-linkage.md) – exact MCP command chains for tuning playbooks - [ams-6-5-guardrails.md](./references/dispatcher-foundation/ams-6-5-guardrails.md) - [mode-specific-verification-matrix.md](./references/dispatcher-foundation/mode-specific-verification-matrix.md) - [test-case-catalog.md](./references/dispatcher-foundation/test-case-catalog.md) - [change-risk-and-rollback-template.md](./references/dispatcher-foundation/change-risk-and-rollback-template.md) - [public-docs-index.md](./references/dispatcher-foundation/public-docs-index.md) - [public-doc-citation-rules.md](./references/dispatcher-foundation/public-doc-citation-rules.md) - [core-7-tools-reference.md](./references/dispatcher-foundation/core-7-tools-reference.md)

IncludedDraws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
