Dispatcher Runtime Incident Response (AMS)

Investigate AMS runtime incidents involving the Adobe Dispatcher Apache HTTP Server module and related HTTPD configuration with an evidence-first workflow.

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:

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

Workflow

1. Quantify impact (monitor_metrics).
2. Gather logs and traces (tail_logs, trace_request). To get the full log sequence for a specific request: use tail_logs to obtain entries (some include pid and tid from dispatcher debug lines), then call trace_request(pid=..., tid=...) to retrieve all log lines for that request. See mcp-tool-orchestration.md § Trace by pid:tid.
3. Apply AMS 6.5 guardrails to triage hypotheses (tier/farm ordering, variable usage, flush exposure, immutable boundaries).
4. Inspect cache behavior (inspect_cache).
5. Correlate with static checks (validate, lint, sdk).
6. Return containment + remediation + rollback.

Verification Scope Selection

Use shared references to select incident evidence depth:

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

Output Contract

Always return:

• incident summary (symptom, impact window, blast radius)
• evidence table (tool, input, finding)
• selected test IDs and outcomes
• probable cause + confidence level
• containment, durable remediation, and rollback
• open risks and missing evidence

Guardrails

• Distinguish observations from inference.
• Do not claim root-cause certainty without corroborating evidence.
• Do not claim runtime verification if host-path/log prerequisites were missing.
• Keep fixes reversible unless user explicitly requests high-risk change.
