Validate Oas

• the developer explicitly wants a fast local re-check only
• the developer already refreshed oas_docs in this session and no relevant inputs changed since then

Refresh flow:

1. Bootstrap dependencies if needed:

yarn kbn bootstrap

2. Regenerate captured OAS snapshots using the same include paths as Buildkite:

node scripts/capture_oas_snapshot \
  --include-path /api/status \
  --include-path /api/alerting/rule/ \
  --include-path /api/alerting/rules \
  --include-path /api/actions \
  --include-path /api/security/role \
  --include-path /api/spaces \
  --include-path /api/streams \
  --include-path /api/fleet \
  --include-path /api/saved_objects/_import \
  --include-path /api/saved_objects/_export \
  --include-path /api/maintenance_window \
  --include-path /api/agent_builder \
  --include-path /api/workflows

3. Rebuild the final OAS documents:

cd oas_docs && make api-docs

After this refresh flow completes, run the scoped validation command.

Source of truth:

• Keep the capture_oas_snapshot include-path list aligned with .buildkite/scripts/steps/checks/capture_oas_snapshot.sh.
• If the Buildkite command changes, update this skill to match it.

Required interaction flow

1. Ask what APIs the developer is working on.
2. Ask for one or more HTTP API paths (for example /api/fleet/agent_policies).
3. Ensure oas_docs is up to date first when needed by following the environment setup flow above.
4. Run validation using those route-style --path filters with --only traditional by default and always include --skip-printing-issues.
5. Return only:
   • VALID, or
   • NOT VALID (and mention debug-oas for details).

Do not skip questions (1) and (2) unless the developer already provided the API paths.

Path format

Use normal route-style API paths for --path:

• /api/fleet/agent_policies
• /api/fleet/agent_policies/{agentPolicyId}

Do not manually convert to JSON pointers. The CLI handles conversion for error filtering internally.

Commands

Environment refresh:

yarn kbn bootstrap
node scripts/capture_oas_snapshot \
  --include-path /api/status \
  --include-path /api/alerting/rule/ \
  --include-path /api/alerting/rules \
  --include-path /api/actions \
  --include-path /api/security/role \
  --include-path /api/spaces \
  --include-path /api/streams \
  --include-path /api/fleet \
  --include-path /api/saved_objects/_import \
  --include-path /api/saved_objects/_export \
  --include-path /api/maintenance_window \
  --include-path /api/agent_builder \
  --include-path /api/workflows
cd oas_docs && make api-docs

Default scoped validation:

node ./scripts/validate_oas_docs.js --only traditional --skip-printing-issues --path <api_route_prefix>

Multiple path filters are supported:

node ./scripts/validate_oas_docs.js --only traditional \
  --skip-printing-issues \
  --path /api/fleet/agent_policies \
  --path /api/fleet/agent_policies/{agentPolicyId}

Optional (only when explicitly requested):

node ./scripts/validate_oas_docs.js --only serverless --skip-printing-issues --path <api_route_prefix>

Default scoping note:

• Prefer --only traditional by default because it matches the common local debugging path and keeps output narrower.
• Use --only serverless only when the developer explicitly asks for it.

Result rules

• Determine status from CLI output:
  • Found 0 errors in ... -> VALID
  • Found N errors in ... where N > 0 -> NOT VALID
• If validation was run without first refreshing obviously stale oas_docs, note that the result may reflect outdated generated inputs and refresh before concluding the spec is clean or broken.
• If CLI output indicates no matched paths (for example None of the provided --path filters matched any content), keep status as VALID but include an explicit warning.
• Output must stay concise:
  • VALID
  • VALID (WARNING: no actual paths were matched.)
  • NOT VALID. Use the debug-oas skill for detailed issues.

Output template

Use exactly one of these responses:

VALID

VALID (WARNING: no actual paths were matched.)

NOT VALID. Use the debug-oas skill for detailed issues.
