salesforce-apex-log-analyzer-skill
T1 read-only runtime skill for Apex debug log retrieval and analysis. This skill is a
diagnostic flashlight — it retrieves log content, identifies governor-limit hits,
surfaces SOQL N+1 patterns, traces exceptions, and produces a prioritized finding report.
It does not execute code, mutate data, or deploy anything.
When This Skill Owns the Task
Use salesforce-apex-log-analyzer-skill when the work requires log-based diagnosis:
"Why is my Account trigger hitting a governor limit?"
"Analyze the debug log from my sandbox — it shows a heap size limit"
"This trigger is slow — can you read the log and find the SOQL bottleneck?"
"I got an unhandled exception in my batch job — here is the log"
"Check if my Queueable is completing successfully in the async log"
Target org alias — the --target-org value from sf org list.
Log identifier — log ID, log file path, user/transaction context, or timeframe.
Accept a pasted log file if the user provides one directly.
Transaction context — which trigger, class, batch job, or user action generated the log.
Goal — governor-limit diagnosis, exception trace, performance analysis, or all.
Sensitivity level — does the log likely contain PII (email, phone, record data from
regulated objects)? Apply stricter redaction if so.
Recommended Workflow
Step 1 — Verify org alias and reachability
sf org display --target-org <alias>
Confirm the org is reachable. Note org type (production vs sandbox) for the audit envelope.
Apply stricter scrutiny for production org logs — log content may contain PII.
Step 2 — List available logs
sf apex get log --list --target-org <alias>
Identify the relevant log(s) by user, timestamp, and log type. If the user provides a log ID,
skip this step and proceed to Step 3.
Step 3 — Retrieve the log
Option A — specific log by ID:
sf apex get log \
--log-id <logId> \
--target-org <alias>
Option B — latest log for current user:
sf apex get log \
--number 1 \
--target-org <alias>
Option C — tail live logs (non-blocking diagnostic):
sf apex taillog \
--target-org <alias> \
--color
Option D — user has pasted log content directly:
Accept the pasted content and proceed to Step 4.
Step 4 — Parse the log in order
Analyze in this sequence per references/log-format-reference.md:
Entry point — identify transaction type (Apex class invocation, trigger, REST callout, batch execute)
Fatal errors and unhandled exceptions — FATAL_ERROR and EXCEPTION_THROWN lines
Governor limit hits — LIMIT_USAGE_FOR_NS entries; compare to limits in references/governor-limit-signatures.md
SOQL patterns — SOQL_EXECUTE_BEGIN / SOQL_EXECUTE_END pairs; look for repeated queries in loop context
Apply all redaction rules (see Redaction Rules section) before emitting any log excerpt
in output. Never echo raw log lines containing record IDs, user IDs, or PII field values.
Step 7 — Emit findings with audit envelope
Score findings against the quality rubric (see below). Emit the full audit envelope.
Propose the smallest correct fix for each Critical and Warning finding.
Step 8 — Route to repair skill
If a code fix is needed, hand off to salesforce-apex-generator-skill with the
specific finding as context. If a deeper test run is needed, route to
salesforce-apex-test-runner-skill.
Quality Scoring Rubric (100-point)
Score the analysis quality before presenting. Threshold: 80+ acceptable.
Dimension
Points
What earns full marks
Governor-limit identification
25
All governor limit hits identified with limit name, current value, and limit ceiling; near-limit warnings included
Root cause clarity
25
Each finding traces to a specific class, method, and line number; not just "SOQL limit hit" but "AccountSelector.getByOwner line 45 in loop at TriggerHandler line 12"
SOQL N+1 detection
15
Repeated SOQL_EXECUTE_BEGIN entries in loop context identified and the responsible pattern named
Sanitization quality
15
All record IDs, user IDs, and PII values redacted in output; no raw log lines echoed; audit envelope populated
Handoff routing
10
Each Critical/Warning finding includes a specific next action and the skill to route to
Audit envelope
10
All required fields present; log ID hashed if PII risk; timestamp accurate
Scoring penalties:
Raw log lines with record IDs echoed: -20 (immediate caveat)
Governor limit hit identified but not traced to source: -15
SOQL in loop not flagged: -15
Missing audit envelope: -15
PII field values in output: score voided (immediate reject)
No View All Data: Unlike the test runner skill, this skill does NOT require
View All Data. Log retrieval uses sf apex get log which operates under the
View Setup and Configuration permission scope.
Read-only: Retrieves log content only. No code execution, no DML, no metadata change.
Log content sensitivity: Debug logs may contain field values from records processed
during the transaction. Apply PII redaction rules strictly.

Redaction Rules
Apply in order before emitting any output. Never bypass for any reason.
OAuth tokens, refresh tokens, session IDs: Never include. Strip from any CLI output.
Salesforce Org IDs (18-char starting with 00D): Replace with <org_id_placeholder>.
Salesforce Record IDs (15/18-char alphanumeric): Replace with <record_id_placeholder>
in all log excerpts. Record IDs appear frequently in USER_DEBUG, DML_BEGIN, and
SOQL_EXECUTE_BEGIN lines.
User IDs (OwnerId, CreatedById, Running User ID, User.Id): Replace with <user_id_placeholder>.
Email addresses in log output: Replace with <email_placeholder> unless the user
explicitly acknowledges PII scope and the org is non-production.
Phone numbers, SSNs, financial account numbers in log output: Replace with
<pii_placeholder>. Flag in redactions_applied.
Session tokens and access tokens in USER_DEBUG lines: Strip entirely. Do not include
a placeholder that implies a token value was present.
Instance URLs: Replace with org alias in output. Do not emit raw instance URLs.
Stack traces: Retain class names and line numbers — required for diagnosis. Replace
any record IDs embedded in exception messages.
Handoff Rules
Finding
Hand off to
Code fix needed (SOQL in loop, DML pattern, exception handling)
Log retrieval fails and the user cannot provide log content directly — stop and explain
that a log ID, user context, or pasted log content is required.
Log content contains fields identified as encrypted (Shield PE / PMLE) — skip those
entries, note the redaction, and analyze the remainder.
The audit envelope cannot be completed — stop until matter_id or org alias is resolved.
The user requests redaction to be disabled — stop and explain the policy.
Log content is from a production org and contains PII fields — apply maximum redaction;
if PII is pervasive and the matter classification does not permit, stop and escalate to
the compliance specialist.
Security Notes
T1 read-only runtime: No code execution, no DML, no metadata mutation.
No View All Data required: Log retrieval operates under View Setup and Configuration
only. This distinguishes this skill from the test runner and reduces its permission footprint.
Log content sensitivity: Apex debug logs may capture field values, user data, and API
payloads. PII and encrypted field redaction is mandatory.
Sanitized output only: All record IDs, user IDs, session tokens, and PII values
redacted before emission. Raw log lines are never echoed.
Structured audit: Every execution produces a complete audit envelope including
pii_risk_assessed and redactions_applied fields.
Revocable: Rotating the Run As account's refresh token immediately revokes all access.
