Repair Argo CD Sync Wave Hook Race
Example session with this skill installed
Two app-of-apps syncs start overlapping hooks with incompatible readiness gates.
Available evidence: sync wave event log (partial). Additional evidence requested: state and configuration snapshot, error and recovery logs, deployment and alert timeline. Review the case, identify open evidence gaps, and do not invent a live test or production change.

Repair Argo CD Sync Wave Hook Race — EVIDENCE-LIMITED REVIEW
Scenario received
Two app-of-apps syncs start overlapping hooks with incompatible readiness gates.
Source register
- S1: sync wave event log — PARTIAL SOURCE PROVIDED.
- S2: state and configuration snapshot — NOT PROVIDED; REQUIRED TO VERIFY.
- S3: error and recovery logs — NOT PROVIDED; REQUIRED TO VERIFY.
- S4: deployment and alert timeline — NOT PROVIDED; REQUIRED TO VERIFY.
Concrete checks
- compare sync-wave annotations and hook delete policies — PRELIMINARY, NOT VERIFIED.
- verify ready-gate timing and rollback sequence — AWAITING CORROBORATING EVIDENCE.
- crosscheck source timestamps identifiers and changed versions — AWAITING CORROBORATING EVIDENCE.
- record exceptions and reversible verification gates — AWAITING CORROBORATING EVIDENCE.
Deliverables / acceptance gates
- sync wave event log evidence map: DRAFT / INCOMPLETE until evidence is validated.
- hook race exception register: DRAFT / INCOMPLETE until evidence is validated.
- ordered sync validation plan: DRAFT / INCOMPLETE until evidence is validated.
Decision
INCOMPLETE — HUMAN REVIEW REQUIRED. Confirm dates, IDs, affected scope, owners and acceptance evidence. Do not claim authorization or execution that did not occur.

About this skill
Race conditions between pre-sync hooks and downstream sync waves can break complex Argo CD deployments, especially in app-of-apps patterns. This skill provides an evidence-led method to identify and fix these overlaps by auditing annotations, delete policies, and readiness gates. It moves beyond guesswork by enforcing a strict classification system for logs and configuration snapshots.
What it does
- Race Condition Auditing by comparing sync-wave annotations against hook delete policies to find execution overlaps.
- Timing Verification of readiness gates and rollback sequences to identify why hooks are firing before dependencies are settled.
- Evidence Mapping that links sync-wave event logs to specific timestamps and resource identifiers.
- Exception Registration to document every hook race and its impact on the deployment timeline.
- Validation Planning to generate an ordered sequence of changes required to resolve the race.
How it works
- Analyze Sources using sync-wave event logs, state snapshots, and deployment timelines provided in the context.
- Crosscheck Identifiers to align source timestamps with changed resource versions across overlapping syncs.
- Classify Evidence by marking every observation as VERIFIED, CONTRADICTED, or UNVERIFIED based strictly on the provided data.
- Draft Validation Plan including reversible verification gates and explicit owner approval steps before any file modifications.
Frameworks & tools
This skill is designed for Argo CD environments utilizing the app-of-apps pattern, Kubernetes manifests, and Helm charts.
Why this beats prompting it yourself
Standard prompts often hallucinate timing data or suggest generic "sleep" fixes. This skill enforces a decision discipline that separates observations from inferences, ensuring you only act on verified log evidence.
Use cases
- Debugging app-of-apps syncs where hooks are executing out of order.
- Resolving hook delete policies that trigger before readiness gates are satisfied.
- Audit trailing logs after a failed deployment to map exact race condition timestamps.
Known limitations
Does not have direct cloud access. Requires local text files for sync logs, configuration snapshots, and event timelines to be provided.

Cannot verify inaccessible environments or data not supplied. Missing or contradictory evidence must be marked INCOMPLETE or UNVERIFIED. Owner approval is required for operational or compliance decisions.
