Sonar Workflow Skill

Sonar provider for the findings-pipeline sonar-issue producer. The provider surface is exactly TWO pure, zero-LLM verbs — no triage judgment lives here:

• fetch_findings — fetch gate-blocking new-code issues from SonarQube/SonarCloud, apply the pre-filter (sonar-rules.json), and file one sonar-issue finding per surviving issue via manage-findings add. The untrusted Sonar message is quarantined under raw_input.{message} (never embedded raw in the top-level detail); the batched manage-findings ingest pass promotes it after validate_struct.
• post_responses — apply already-decided triage dispositions back to Sonar (a do_transition dismissal: wontfix for suppressed, falsepositive for rejected), keyed by each finding's own hash_id.

Both verbs FAIL LOUD when Sonar is not configured (a typed unconfigured status). Consumer dispatch lives in `phase-6-finalize/workflow/sonar-roundtrip.md`.

Architectural context: This SKILL.md owns the producer-side CLI surface. For the producer→store→consumer→gate flow that connects this producer to the unified store, the per-domain ext-triage consumer dispatch, and the invariant gate, see `ref-workflow-architecture/standards/findings-pipeline.md`.

Enforcement

Execution mode: Two pure provider verbs — fetch_findings files new-code Sonar issues to the ledger (untrusted message quarantined under raw_input); post_responses transmits already-decided triage dismissals back to Sonar. Triage judgment lives in the consolidated triage pass, NOT in this provider.

Prohibited actions:

• Never make a triage decision inside the provider verbs — they only fetch and transmit already-decided dispositions
• Never read a finding's raw_input.* from a triage/response surface — read the top-level fields promoted by manage-findings ingest
• Never suppress Sonar issues without documented justification
• Never modify Sonar configuration or quality profiles
• Never skip build verification after implementing fixes

Constraints:

• Suppressions require inline comments explaining the rationale
• Fix-vs-suppress decisions must be logged

Workflows

Workflow 1: Fetch & Store Issues (Producer-Side)

Purpose: Stage gate-blocking Sonar issues into the per-type finding store, then let the LLM consumer drive fix-vs-suppress decisions from the stored findings.

Producer-side flow: sonar.py fetch_findings is the only callable surface and the single authority on PR-scoped new-code issue enumeration. Before enumerating it performs a synchronous bounded in-Python CE-readiness wait — it polls the Compute-Engine analysis-task state (via /api/ce/component, PR-scoped when --pr is supplied) until the task has settled (SUCCESS/FAILED/CANCELED with an empty queue) or the wait budget expires. The wait reuses the ci_base.poll_until(...) bounded-polling framework (the same framework that replaced blocking shell sleeps for checks wait); it is NOT a shell polling loop. The budget resolves from the plan-local execution-manifest step-params snapshot for default:sonar-roundtrip — the prefix-stripped ce_wait_timeout_seconds param (default 600, the direct sibling of checks_wait_timeout_seconds), read in a single one-stop call alongside the step's touched_file_cleanup and do_transition params via manage-execution-manifest step-params get --phase 6-finalize --step-id default:sonar-roundtrip (the plan-local runtime source) — overridable by an explicit --ce-wait-timeout flag. After CE settles it fetches the PR-scoped new-code issues (pullRequest + inNewCodePeriod=true + unresolved), applies the sonar-rules.json pre-filter (drops issues already documented as suppressable via NOSONAR / test-acceptable rules), and writes one sonar-issue finding per surviving issue via manage-findings add. Severity is derived from the Sonar severity (BLOCKER/CRITICAL/MAJOR → error, MINOR → warning, INFO → info), the rule key is captured in the finding's rule field, and the project key is captured in module.

Verified count + undecidable discriminator: the returned contract carries a verified new_code_issue_count plus a count_status discriminator (confirmed | undecidable). On a confirmed CE-settled run the count is the real PR-scoped new-code total and a reported 0 is a confirmed PR-scoped zero. When the CE wait times out (analysis still processing) OR a REST/auth failure blocks confirmation, the contract carries new_code_issue_count: null, count_status: undecidable, and a count_status_reason — never a false 0.

Scan-summary marker: every fetch also writes one attestation row to artifacts/findings/sonar-scan-summary.jsonl — written unconditionally, including when new_code_issue_count == 0 and on undecidable — so an absent file can never be confused with "not checked." The marker lives in the same archive-surviving findings directory as pr-comment.jsonl (resolved via the shared _findings_core.get_findings_dir) and is read by `phase-6-finalize/workflow/sonar-roundtrip.md` at its success gate. The full row schema is documented in the Scan-Summary Marker section below.

Steps:

1. Fetch & Store:

   python3 .plan/execute-script.py plan-marshall:workflow-integration-sonar:sonar fetch_findings \
     --plan-id {plan_id} --project {project_key} [--pr {pr_number}] [--severities BLOCKER,CRITICAL] [--types BUG,VULNERABILITY] [--ce-wait-timeout {secs}]

   Output reports the verified new_code_issue_count and count_status (confirmed | undecidable, with count_status_reason on undecidable), the pre-filter counters count_fetched / count_skipped_suppressable / count_stored, the scan_summary_path of the written attestation row, and producer_mismatch_hash_id (set when count_stored ≠ count_fetched − count_skipped_suppressable; the mismatch is also persisted as a Q-Gate finding under phase 5-execute with title prefix (producer-mismatch)). When that mismatch finding's own persist is REJECTED, producer_mismatch_hash_id stays null and the output carries qgate_persist_failed: true plus qgate_persist_failure{title, detail, message} — the mismatch content that never reached the store, with the primitive's rejection message. Both fields are absent when the mismatch finding landed (or when there was no mismatch). Read qgate_persist_failed, not a null hash id, to tell a lost mismatch finding from no mismatch at all; status stays success because the fetch itself succeeded.

2. Query Stored Findings:

   python3 .plan/execute-script.py plan-marshall:manage-findings:manage-findings list --plan-id {plan_id} --type sonar-issue

3. Ingest, then process — the untrusted Sonar message was quarantined under raw_input.{message} at file time. Run the single batched manage-findings ingest --plan-id {plan_id} pass, which validates and promotes it to the top level; the consolidated triage pass then decides fix-vs-suppress from the clean top-level fields (never raw_input.*). After acting on each finding, call manage-findings resolve --hash-id {hash} --resolution fixed|suppressed|accepted --detail "{rationale}"; the rationale becomes the resolution_detail that sonar post_responses transmits as a Sonar dismissal.

Raw REST search (ad-hoc)

For ad-hoc inspection or non-finding-store integrations, sonar_rest.py search is the raw REST surface (see Canonical invocations → sonar_rest — search). It outputs structured TOON directly. Producer-side flows MUST use sonar.py fetch_findings.

---

Workflow 2: Triage & Respond (Consumer-Side)

Purpose: Drive the stored sonar-issue findings through the consolidated triage decision core, then transmit the terminal dismissals back to Sonar — the INGEST → TRIAGE → RESPOND tail of the FIND → INGEST → TRIAGE → RESPOND flow whose FIND step is Workflow 1.

Input: sonar-issue findings already populated in the per-type store via Workflow 1.

This provider makes NO triage decision. The fix-vs-suppress-vs-reject decision core is owned by the consolidated triage pass — see `../plan-marshall/workflow/triage.md` (the per-finding FIX / SUPPRESS / ACCEPT / REJECT core, with smart grouping and the escalation guards) and `../plan-marshall/workflow/verification-feedback.md` (the finalize-phase dispatch that drives that core over the finding store). This workflow only stages the findings for that core and transmits the dispositions it already recorded; there is no script-side classification call here.

Steps:

1. Query Findings:

   python3 .plan/execute-script.py plan-marshall:manage-findings:manage-findings list --plan-id {plan_id} --type sonar-issue

2. Ingest (untrusted message containment)

   Run the single batched ingest pass — the same containment boundary described in Workflow 1 step 3 above: it validates and promotes each quarantined raw_input.{field} to the clean top-level fields, and triage then reads those top-level fields only, never raw_input.*.

   python3 .plan/execute-script.py plan-marshall:manage-findings:manage-findings ingest --plan-id {plan_id}

3. Triage (decision core — not owned here)

   The consolidated triage pass reads the clean top-level fields promoted by the ingest pass (never the raw un-ingested raw_input.*) and records one terminal resolution per finding via manage-findings resolve. The decision logic lives in triage.md / verification-feedback.md; this provider contributes no classification. Each finding ends at one of: fixed (cleared in code), suppressed (dismiss on Sonar as wontfix), rejected (dismiss on Sonar as falsepositive), or accepted / taken_into_account (no Sonar action). Record the rationale as resolution_detail — it is the text the RESPOND step transmits:

   python3 .plan/execute-script.py plan-marshall:manage-findings:manage-findings resolve \
     --plan-id {plan_id} --hash-id {hash} --resolution fixed|suppressed|rejected|accepted --detail "{rationale}"

4. Apply code changes for fixed findings

   For a finding resolved fixed, read the file at the issue location and apply the fix with the Edit tool. A suppressed / rejected finding is dismissed on Sonar in step 5 (not annotated in code); accepted / taken_into_account needs no action.

5. RESPOND — transmit dismissals back to Sonar (keyed by hash_id):

   python3 .plan/execute-script.py plan-marshall:workflow-integration-sonar:sonar post_responses \
     --plan-id {plan_id} --project {project_key}

   post_responses maps each terminal disposition to its Sonar do_transition (suppressed → wontfix, rejected → falsepositive); fixed / accepted / taken_into_account get no Sonar action. It is idempotent — a finding whose dismissal was already transmitted carries a responded marker and is skipped on a re-run, so re-invoking the verb never re-POSTs the same dismissal. This replaces the retired per-finding sonar_rest transition call; the raw REST transition surface remains available only for ad-hoc inspection (see Canonical invocations → sonar_rest).

---

Gate Diagnosis

When diagnosing a Sonar quality-gate failure, MUST read the verdict through the authoritative REST verbs on sonar_rest.py — never the sonarqube MCP convenience tool, which returns stale data during incidents:

• gate-status — the authoritative quality-gate verdict from GET /api/qualitygates/project_status: the overall gate status plus one entry per condition (metricKey, comparator, errorThreshold, actualValue, per-condition status). This is the exact verdict the Maven Sonar plugin gates on.
• ce-status — the Compute-Engine analysis-task status from GET /api/ce/activity (+ GET /api/ce/component). Use it to distinguish an infra processing failure (errorType / errorMessage on a task) from a real gate failure.
• hotspots — security hotspots from GET /api/hotspots/search. Hotspots drive new_security_hotspots_reviewed and are NOT returned by the search issues verb, so a hotspots-only gate failure is invisible without this verb.

Authoritative-verb rule: a CI-red / tool-green disagreement means trusting CI. The CI build runs the same GET /api/qualitygates/project_status verdict that gate-status reports; if a convenience tool reports green while CI reports red, the convenience tool is stale — trust the CI result and re-read through gate-status / ce-status.

All three verbs are read-only (single GET, no transition behavior) and accept --project plus an optional --branch or --pr. See Canonical invocations below for the exact surface.

---

Scripts

Script: plan-marshall:workflow-integration-sonar:sonar → sonar.py (producer-side fetch + pre-filter + finding store)
Script: plan-marshall:workflow-integration-sonar:sonar_rest → sonar_rest.py (raw REST API client: issue search / transition / metrics + the gate-status / ce-status / hotspots gate-diagnosis verbs)

sonar.py fetch_findings

Purpose: Producer-side flow and single authority on PR-scoped new-code issue enumeration — perform a synchronous bounded CE-readiness wait, fetch the PR-scoped new-code issues via the REST client, apply the pre-filter, persist one sonar-issue finding per surviving issue, and write the verified-scan attestation marker.

Usage:

python3 .plan/execute-script.py plan-marshall:workflow-integration-sonar:sonar fetch_findings \
  --plan-id {plan_id} --project {project_key} [--pr {pr}] [--severities ...] [--types ...] [--ce-wait-timeout {secs}]

Output: TOON with the verified new_code_issue_count and count_status discriminator (confirmed | undecidable, plus count_status_reason on undecidable), the pre-filter counters (count_fetched, count_skipped_suppressable, count_stored), the list of stored finding hash_ids, the scan_summary_path of the written attestation row, and producer_mismatch_hash_id when applicable. A confirmed 0 is a confirmed PR-scoped zero; a CE-timeout or auth/REST failure yields count_status: undecidable with new_code_issue_count: null — never an inferred 0.

Scan-Summary Marker (sonar-scan-summary.jsonl)

Every fetch_findings run appends one attestation row to artifacts/findings/sonar-scan-summary.jsonl (resolved via the shared _findings_core.get_findings_dir, so it lives in and survives manage-status archive exactly like pr-comment.jsonl). The row is written unconditionally — including when new_code_issue_count == 0 and when count_status == undecidable — so a verified zero is a positive on-disk fact and an absent file unambiguously means "not checked." This is a distinct artifact kind from sonar-issue.jsonl (a producer-written attestation file, not a finding store managed by the manage-findings add/resolve verbs), and is read by `phase-6-finalize/workflow/sonar-roundtrip.md` at its success gate (which requires count_status == confirmed).

Row fields (written by sonar.py:_write_scan_summary):

Field	Type	Always present	Description
count_status	string	yes	confirmed (CE settled in budget) or undecidable (CE timeout or REST/auth failure)
new_code_issue_count	int | null	yes	Verified PR-scoped new-code total on confirmed; null on undecidable — never a false 0
count_status_reason	string	no	Human-readable reason; emitted only on undecidable (omitted entirely on confirmed)
pr	string | null	yes	PR number the fetch was scoped to (null for a non-PR / branch fetch)
project	string	yes	Sonar project key the fetch enumerated
scanned_sha	string	yes	The worktree HEAD SHA the scan attests to; the empty string "" when the SHA cannot be resolved (not a git tree / git unavailable) — the row is still written
ts	string	yes	ISO-8601 UTC timestamp of the fetch

Write-even-at-count==0 guarantee: the row is appended on every fetch_findings, so a confirmed new_code_issue_count: 0 is a positive on-disk attestation of a verified zero. Survives-archive guarantee: the file resolves through _findings_core.get_findings_dir, so it lives in and survives manage-status archive exactly like pr-comment.jsonl. Distinct artifact kind from sonar-issue.jsonl: this is a producer-written attestation file (append-only, not managed by the manage-findings add/resolve verbs). See `manage-findings/standards/jsonl-format.md` § "Producer-Written Attestation Files" for the artifacts/findings/ inventory entry.

Issue Classification

standards/sonar-rules.json is a pre-filter only for the producer-side fetch_findings flow. Suppressable rules (rules already documented as suppressable, test-acceptable rules) are dropped before findings are written; severity/type boost mappings derive the finding severity field. Final fix-vs-suppress classification of stored findings belongs to the consolidated triage pass reading the validated top-level fields (the message promoted from raw_input.{message} by the manage-findings ingest pass) — never the raw un-ingested raw_input.*.

Key principles:

• Always fix: VULNERABILITY, SECURITY_HOTSPOT, and BLOCKER severity (enforced by script)
• Fix preferred: CRITICAL severity, BUG type, resource leaks
• May suppress: Rules listed in suppressable_rules (with documented justification)
• Test exceptions: Rules in test_acceptable_rules are acceptable in test files

Supported languages: Java, JavaScript, TypeScript, Python. Unrecognized rules fall back to the Sonar issue message for triage guidance.

For triage override guidance, see ref-workflow-architecture → "Triage Override Guidance".

Suppression Format

Generated by sonar.py:get_suppression_string() based on file extension and rule prefix:

Java: // NOSONAR java:S1234 - reason for suppression

JavaScript/TypeScript: // NOSONAR javascript:S1234 - reason for suppression

Python: # NOSONAR python:S1234 - reason for suppression

Error Handling

Failure	Action
REST API failure	Report error with HTTP status. Verify credentials configured and project key is correct.
REST API returns empty	No issues found — report success with zero counts.
triage failure (invalid JSON)	Log warning, skip the issue, continue processing remaining.
Fix implementation failure	Report which file/line failed. Do not suppress as fallback — ask the caller.
REST status change failure	Log warning, continue — marking resolved is best-effort.
Build verification failure after fixes	Report failing tests/compilation. Do not commit broken fixes.

Standards (Load On-Demand)

Standard	When to Load
