Analyze symptom

SC4SAP Analyze Symptom

Performs structured root cause analysis for SAP operational incidents by connecting to the live SAP system through MCP. Auto-collects evidence from dumps, system state, recent transports, and code call graphs before asking the user any question.

<Purpose> sc4sap:analyze-symptom is the first-line triage skill for SAP production incidents. Rather than bombarding the user with questions, it **directly investigates the SAP system through MCP** to gather evidence it can collect on its own. It then asks the user only about gaps that MCP cannot fill, narrows hypotheses to 2–3 categories, and produces SAP Note search keywords plus recommended next actions. </Purpose>

<Response_Prefix> Every response triggered by this skill MUST begin with [Model: <main-model> · Dispatched: <sub-summary>] per ../../common/model-routing-rule.md § Response Prefix Convention. </Response_Prefix>

<Phase_Banner> Multi-phase skill. Before each Agent(...) dispatch, emit ▶ phase=<id> (<label>) · agent=<name> · model=<Opus 4.7|Sonnet 4.6|Haiku 4.5> per ../../common/model-routing-rule.md § Phase Banner Convention. </Phase_Banner>

<Use_When>

• User reports a symptom using words like "error", "dump", "failing", "broken", "not working", "timeout", "slow"
• User has at least one clue: error message, TCode, program name, job name, or affected user/data
• User is unsure which log or transaction to inspect (ST22, SM21, SLG1, SU53, SM13, SM58, WE02, etc.)
• Need to classify whether the issue is custom development vs SAP standard
• Need to trace root cause of an incident that started after a recent transport or patch </Use_When>

<Do_Not_Use_When>

• Root cause is already identified and only a code fix is needed — use /sc4sap:create-program or direct MCP Update* calls
• Pure static code quality review — use /sc4sap:analyze-code
• Need to create a new ABAP object — use /sc4sap:create-object
• Conceptual or configuration-guide question — use a module consultant agent directly </Do_Not_Use_When>

<Session_Trust_Bootstrap> MANDATORY — runs as Step 0 before any MCP call or user interaction.

Invoke /sc4sap:trust-session with parent_skill=sc4sap:analyze-symptom to pre-grant all MCP tool + file-op permissions for this session (eliminates per-tool "Allow this tool?" prompts during auto-investigation — RuntimeAnalyzeDump, ListTransports, GetWhereUsed, etc.).

• If .sc4sap/session-trust.log already has a line within the last 24h, skip silently.
• Otherwise run it and surface the one-line confirmation.

Full spec: see ../trust-session/SKILL.md. </Session_Trust_Bootstrap>

<Core_Principles>

• MCP-first: Before asking the user, investigate the SAP system directly with MCP. Never re-ask what MCP can answer.
• Evidence over assumption: Do not speculate. No "probably" statements without supporting MCP or user-provided evidence.
• Minimal questions: At most 3 questions per round. Skip any question whose answer is already known via MCP.
• Hypothesis narrowing: Reduce candidate causes to 2–3 from the 8-category framework; each must carry a confidence level and a confirmation path.
• Actionable output: Every hypothesis must include the next evidence step (another MCP call, a TCode, or an escalation target).
• Customization cache first (local, before live MCP) when a Z/Y object or customized SAP include appears in the trace**: read .sc4sap/customizations/<MODULE>/{enhancements,extensions}.json and correlate — a Z* class in a dump may be a known BAdI impl, a customized MV45AFZZ/ZXRSRU01 may be a recorded form-based exit, a failing field may be a recorded append. Follow common/customization-lookup.md. If the cache is absent, suggest /sc4sap:setup customizations but do not block the current analysis. </Core_Principles>

<Analysis_Framework> All hypotheses must map to one of these 8 root cause categories:

Category	Typical Symptoms	Key Signals
Master / Input data	Only specific data fails, others succeed	Data values, related master records
Authorization	Only specific users fail	SU53, STAUTHTRACE, recent role changes
Customizing	Only specific org units affected	SPRO values, recent customizing transports
Interface / RFC / Batch	External integration fails	SM58, SMQ1/2, SM37, WE02, BD87
Custom development	Z*/Y* objects in call stack	Recent Z* transports, GetWhereUsed
Standard SAP bug	Only standard objects in stack; right after SP upgrade	SAP Note search, kernel/SP level
Performance / Locks / DB	Timeouts, increased wait times	ST05, SAT, SM12, SQLM
Operational procedure	Step order or prerequisite violated	Month-end, dependency job status

Every hypothesis presented to the user must declare its category explicitly. </Analysis_Framework>

<Evidence_Collection_Matrix> Evidence collection strategy — prefer MCP auto-query, fall back to manual TCode guidance:

Symptom Type	MCP Auto-Query	Manual TCode
Short dump / runtime error	RuntimeListDumps, RuntimeGetDumpById, RuntimeAnalyzeDump	ST22
Performance / long runtime	RuntimeRunProgramWithProfiling, RuntimeAnalyzeProfilerTrace, RuntimeListProfilerTraceFiles	ST05, SAT, SQLM
Suspect program/class logic	ReadClass/ReadProgram, GetAbapAST, GetAbapSemanticAnalysis, GetWhereUsed	SE80, SE24, SE38
Recent change tracking	ListTransports, GetTransport, GetObjectInfo (Author/Changed-by)	SE09, SE10, SE16 → E070
Z*/Y* object or customized SAP include in trace	Local file read: .sc4sap/customizations/<MODULE>/enhancements.json (→ badiImplementations[], cmodProjects[], formBasedExits[]) and .sc4sap/customizations/<MODULE>/extensions.json (→ appendStructures[])	n/a — local cache only
Enhancement / BAdI	GetEnhancements, GetEnhancementImpl, GetEnhancementSpot	SE18, SE19, SMOD, CMOD
System / session info	GetSession	/n (status), /o SM04
Table schema (not rows)	GetTable, GetStructure, GetView, GetDataElement, GetDomain	SE11
Unit test results	GetUnitTestResult, RunUnitTest	SE80 → test class
Authorization error	(MCP not supported)	SU53, STAUTHTRACE
Application log	(MCP not supported)	SLG1
System log	(MCP not supported)	SM21
Update error	(MCP not supported)	SM13
RFC / tRFC / qRFC	(MCP not supported)	SM58, SMQ1, SMQ2
Background job	(MCP not supported)	SM37
IDoc	(MCP not supported)	WE02, WE05, BD87
OData / Fiori	(MCP not supported)	/IWFND/ERROR_LOG, /IWBEP/ERROR_LOG

Rule: For any MCP-supported item, never ask the user — query it directly. </Evidence_Collection_Matrix>

<Workflow_Steps> MANDATORY: Follow the step sequence defined in workflow-steps.md.

Per-step model allocation (skill main thread runs on Haiku 4.5 per frontmatter; heavy analysis is delegated):

Step	Owner	Model	Role
0 Trust	skill-to-skill	Haiku	permission bootstrap
1 Initial Triage	main	Haiku	clue parsing + GetSession
2 Investigate + Gap + Narrow	sap-debugger with model: "opus" override	Opus 4.7	auto-investigation (dump/transport/code/enhancement/customization) + gap identification + 2–3 hypotheses with confidence/evidence/confirmation-path + priority questions. One dispatch per round.
3 User Questions	main	Haiku	render debugger's priority questions + collect answers (max 3/round)
(multi-round) repeat Step 2	sap-debugger (Opus override)	Opus 4.7	re-run with new user-supplied evidence
4 SAP Note Keywords	main	Haiku	assemble copy-paste search strings from debugger's sap_note_hints
5 Recommended Actions	main	Haiku	static classification by actor (immediate / access-required / escalation)
6 Escalation Routing	main	Haiku	point to next skill or agent (sap-debugger write mode, /sc4sap:analyze-code, module consultant, etc.)

sap-debugger's tool set already covers RuntimeAnalyzeDump, profiler, transport queries, code reads, enhancement lookup, and customization cache reads — see the agent's Investigation_Protocol for the full inventory. The model: "opus" override is appropriate here because symptom triage is cross-file reasoning (dump × transport × source × customization × profiler) with ambiguity resolution (8-category framework), which common/model-routing-rule.md § Tier 2 classifies as Opus territory. </Workflow_Steps>

<Question_Strategy> Rule: max 3 questions per response. Never re-ask what MCP already answered.

Priority when information is missing:

1. Exact error text + message class/number — the strongest SAP Note search key
2. TCode / App / Program / Job where the error occurs
3. Reproduction conditions (always vs intermittent; user/data/org specificity)

Situation-specific follow-ups:

• Authorization suspected: Does another user succeed with the same input? Any SU53 capture?
• Batch suspected: Does manual execution also fail? Any recent variant change?
• Interface suspected: Does SM59 Connection Test succeed? What is the IDoc status code (51/52/53/64)?
• Custom development suspected: (First run ListTransports + GetWhereUsed, then) Does TR candidate X match the timing of the incident?
• Standard bug suspected: Release/SP auto-detected via GetSession. Does the same symptom reproduce on QAS/DEV?
• Performance suspected: How much slower than usual? Which resource saturates first — DB / CPU / memory? </Question_Strategy>

<Output_Format> Per-round report template and the final-round consolidated report structure live in output-format.md. Follow it literally for both intermediate rounds and the final analysis. </Output_Format>

<MCP_Tools_Used>

Only GetSession is called by the main thread (Step 1 intake). Every other tool below is called by the sap-debugger agent inside its Step 2 dispatch — the orchestrator never holds dump payloads, full source, or transport object lists.

Main thread (Haiku · Step 1 only)

• GetSession — system ID, client, release, SP level, current user

Reviewer agent (sap-debugger with Opus override · Step 2 dispatch)

Dump Analysis

• RuntimeListDumps — recent dumps
• RuntimeGetDumpById — specific dump detail
• RuntimeAnalyzeDump — automated dump analysis (location, variables, stack)

Performance Profiling

• RuntimeCreateProfilerTraceParameters — profiler setup
• RuntimeRunProgramWithProfiling / RuntimeRunClassWithProfiling — reproducible run with profiler
• RuntimeListProfilerTraceFiles / RuntimeGetProfilerTraceData / RuntimeAnalyzeProfilerTrace — trace analysis

Transport / Change Tracking

• ListTransports — recent transports
• GetTransport — objects included in a transport
• GetObjectInfo — author, last changed by, modification date

Code Analysis

• ReadClass / ReadProgram / ReadFunctionModule / ReadInterface — source
• GetProgFullCode — full source including includes
• GetAbapAST — parse tree
• GetAbapSemanticAnalysis — semantic analysis (activation / type errors)
• GetWhereUsed — caller graph
• GetInactiveObjects — any inactive objects remaining

Enhancement

• GetEnhancements — enhancements attached to program
• GetEnhancementImpl / GetEnhancementSpot — implementation and spot detail

Data Dictionary (schema only — not row extraction)

• GetTable / GetStructure / GetView / GetDataElement / GetDomain

Search

• SearchObject — existence / type check
• DescribeByList — batch metadata lookup

<Common_Pitfalls_To_Avoid>

• ❌ Asking the user for information MCP can retrieve (system info, program source, recent transports)
• ❌ Firing 4+ questions at once
• ❌ Diagnosing a root cause without an error message in hand
• ❌ Skipping RuntimeListDumps when a dump is suspected and speculating instead
• ❌ Deflecting with "contact Basis / dev team" without a concrete checklist and evidence
• ❌ Claiming a standard SAP bug before attempting a SAP Note search
• ❌ Blaming recent changes without inspecting transport history via ListTransports
• ❌ Listing 4+ hypotheses (narrow to 2–3) </Common_Pitfalls_To_Avoid>
