* feat: add per-release continue-on-error support

Work in progress for discussion #2799.

This introduces the initial release-level configuration needed to
continue processing independent releases after a deployment failure.
The DAG execution and failure propagation behavior are still being
implemented.

* fix: address review findings for continueOnError

Review fixes for the per-release continueOnError feature:

1. Regenerate values-file ID hashes in pkg/state/temp_test.go — adding
   ContinueOnError to ReleaseSpec shifts generateValuesID hashes, which
   broke TestGenerateID (the test file notes these must be regenerated
   whenever ReleaseSpec changes).

2. Remove the dead skippedErrors variable in withBatches and instead log
   each skipped release with logger.Warnf at decision time, so users see
   why a release never ran instead of only learning from the final error
   list.

3. Aggregate all errors from a state file instead of returning only
   errs[0] in visitStatesWithContext/processStateFileParallel. With
   continueOnError, multiple releases can fail or be skipped in one run;
   reporting only the first error hid the skip errors (and other
   failures), contradicting the feature's contract. Single-error
   rendering is unchanged.

4. Gate tolerated errors on ReleaseErrorCodeFailure so that non-failure
   release errors (e.g. helm-diff's "changes detected" exit code 2 can
   never enable continuation or block dependents.

5. Report skipped-release messages with the dependency's plain release
   name instead of its kubeContext/namespace-qualified needs id
   (e.g. dependency database instead of default/default/database),
   matching the documented message format.

6. Restructure the withBatches helpers into guard-clause style
   (filterBlockedReleases, toleratesBatchErrors) and drop the test-only
   logger nil-guards in favor of a nop logger in tests.

7. Add end-to-end coverage through App.Sync with the exectest fake helm:
   independent releases continue after a tolerated failure, dependents
   are skipped with an explicit error, the exit code stays non-zero, and
   fail-fast remains the default without continueOnError. Also cover the
   non-failure error code case at the withBatches level.

8. Use new(true) instead of a boolPtr helper (CI-enforced check-modernize)
   and document the failure-handling interaction in docs/releases.md.

Helmfile Agent Skill

Expert guidance for Helmfile v1.1, a declarative spec for deploying Helm charts to Kubernetes.

Installation

Using skills.sh CLI

npx skills add helmfile/helmfile --skill helmfile

Manual Installation

For Claude Code

mkdir -p ~/.claude/skills
cp -r skills/helmfile ~/.claude/skills/

For Cursor

mkdir -p ~/.cursor/skills
cp -r skills/helmfile ~/.cursor/skills/

For OpenCode

mkdir -p ~/.agents/skills
cp -r skills/helmfile ~/.agents/skills/

What This Skill Covers

  • Status: Helmfile v1.0/v1.1 released, supports Helm 3.x and Helm 4.x
  • Configuration Structure: Full helmfile.yaml reference with all release fields
  • CLI Commands: sync, apply, diff, destroy, template, fetch, unittest, show-dag, write-values, and more
  • Templating: Built-in objects, template functions (env, exec, readFile, fetchSecretValue, expandSecretRefs), partials
  • Environments: Multi-environment setup, HCL values, conditional releases
  • Values Merging: Data flow and precedence (bases -> root values -> env values -> HCL -> secrets -> CLI overrides)
  • Layering: Bases, release templates, nested helmfiles
  • Hooks: Lifecycle hooks (prepare, preapply, presync, preuninstall, postuninstall, postsync, cleanup) with kubectlApply
  • Advanced Features: Kubedog resource tracking, Kustomize integration, strategic merge patches, JSON patches, transformers, chart dependencies, remote secrets (vals)
  • Best Practices: Directory structure, DRY configuration, labels filtering, missing keys handling
  • Troubleshooting: Common issues and solutions, Helm 4 compatibility

Usage

Once installed, simply ask your AI agent questions about Helmfile:

  • "Create a helmfile.yaml for deploying Prometheus"
  • "How do I set up multi-environment deployments?"
  • "Explain release templates and layering"
  • "Help me troubleshoot a Helmfile sync issue"
  • "How do I use kubedog for resource tracking?"
  • "Set up hooks for CRD installation before sync"
  • "How do I use vals for remote secrets?"
