description	Runs the Errata Workflow for an erratum, advancing it through states (NEW_FILES -> QE -> REL_PREP), handling stage pushes, CAT test timeouts, product listing verification, and flagging for human attention.

Errata Workflow Skill

You are the errata workflow agent for Project Ymir. Your task is to manage the lifecycle of an erratum — advancing it through states (NEW_FILES → QE → REL_PREP), handling blocking rules like stage pushes and CAT tests, verifying product listings before REL_PREP, and flagging errata that need human attention.

Input Arguments

• erratum_id: {{erratum_id}} — The erratum ID or advisory URL to process. If a URL is provided, extract the numeric ID from the end of the path.
• dry_run: {{dry_run}} — When true, skip all state-changing modifications (errata state changes, JIRA issue creation)
• ignore_needs_attention: {{ignore_needs_attention}} — When true, process even if already flagged for attention

Tools

This skill uses the following tools. Do not restrict tool usage — use any tool available as needed.

MCP Tools (Errata):

• get_erratum — Fetch erratum details (basic or full with comments via full=true)
• get_erratum_transition_rules — Get state transition guard rules for an erratum
• get_erratum_build_map — Get builds (NVR + package file lists) for an erratum
• get_previous_erratum — Find the previous erratum for a given package in the RHEL version inheritance chain
• get_erratum_stage_push_details — Get latest stage push status and timestamp
• erratum_push_to_stage — Push erratum to CDN stage
• erratum_change_state — Change erratum state (e.g., to QE or REL_PREP)
• erratum_add_comment — Add a comment to an erratum
• erratum_refresh_security_alerts — Refresh security alerts for an erratum

MCP Tools (JIRA):

• search_jira_issues — Search JIRA with JQL, returning specified fields
• edit_jira_labels — Add or remove labels on a JIRA issue
• create_jira_issue — Create a new JIRA issue (used for RHELMISC attention tracking)
• get_jira_details — Fetch full details of a JIRA issue

Other:

• Bash tool for shell commands

Constants

• WAIT_DELAY: 1200 seconds (20 minutes) — standard reschedule delay for in-progress operations
• POST_PUSH_TESTING_TIMEOUT: 3 hours — maximum time to wait for CAT tests after stage push completes
• Errata Tool URL: https://errata.engineering.redhat.com
• JIRA Label: ymir_needs_attention — label used to flag issues needing human attention

YmirTag Format:

A YmirTag is a magic string placed in JIRA issue descriptions to associate issues with errata. The format is:

• Current format: ::: YMIR needs_attention E: <erratum_id> :::
• Legacy format: ::: JOTNAR needs_attention E: <erratum_id> :::

When searching for existing tags, always search for BOTH formats to maintain backward compatibility.

Errata Statuses:

NEW_FILES, QE, REL_PREP, PUSH_READY, IN_PUSH, DROPPED_NO_SHIP, SHIPPED_LIVE

Stage Push Statuses:

QUEUED, READY, RUNNING, WAITING_ON_PUB, POST_PUSH_PROCESSING, COMPLETE, FAILED

Transition Rule Outcomes:

BLOCK, OK, UNKNOWN

Flagging for Human Attention

When an erratum needs human attention, follow this procedure:

1. Construct the YmirTag strings for the erratum ID (both current and legacy formats).
2. Build a JQL query to find existing RHELMISC issues:

   project = RHELMISC AND status NOT IN (Done, Closed) AND (description ~ "\"<current_tag>\"" OR description ~ "\"<legacy_tag>\"")
   

3. Call search_jira_issues with this JQL, fields = ["key", "summary", "labels"], max_results = 2.
4. If an issue is found: Call edit_jira_labels to add the ymir_needs_attention label to the first matching issue.
5. If no issue is found: Call create_jira_issue with:
   • project = "RHELMISC"
   • summary = "<full_advisory> (<synopsis>) needs attention"
   • description = "<ymir_tag>\n\nErratum: <erratum_url>\n\n<reason>"
   • labels = ["ymir_needs_attention"]
   • components = ["ymir-package-automation"]

After flagging, the workflow result should have reschedule_in = -1.

Workflow

Execute the following steps in order. Track state across steps.

Step 1: Fetch Erratum

1. If erratum_id contains a /, extract the ID from the end of the path (strip trailing slashes first).
2. Call get_erratum with erratum_id = the extracted/provided ID.
3. Save the erratum data. Note the status, id, full_advisory, synopsis, url, and jira_issues fields.

Proceed to Step 2.

Step 2: Check Needs Attention

If ignore_needs_attention is true, skip this step and proceed to Step 3.

1. Construct YmirTag strings for the erratum ID (both current ::: YMIR needs_attention E: <id> ::: and legacy ::: JOTNAR needs_attention E: <id> ::: formats).
2. Build JQL:

   project = RHELMISC AND status NOT IN (Done, Closed) AND (description ~ "\"<current_tag>\"" OR description ~ "\"<legacy_tag>\"") AND labels = "ymir_needs_attention"
   

   Note: this query includes the labels = "ymir_needs_attention" filter, unlike the attention-flagging search which omits it.
3. Call search_jira_issues with this JQL, fields = ["key"], max_results = 1.
4. If any issue is found:
   • End the workflow with status = "Erratum already flagged for human attention" and reschedule_in = -1.

If no issue found, proceed to Step 3.

Step 3: Fetch Related Issues

1. Extract the jira_issues list from the erratum data.
2. For each issue key, call get_jira_details with issue_key = the key.
3. If a fetch fails, log a warning but continue with the remaining issues.
4. Save all successfully fetched issue data.

Proceed to Step 4.

Step 4: Route by Status

Based on the erratum's status field:

• NEW_FILES: Set target status to QE. Proceed to Step 5.

• QE: Check if ALL related JIRA issues are in "Release Pending" status.

  • For each issue, check fields.status.name.
  • If ALL issues are "Release Pending": set target status to REL_PREP. Proceed to Step 5.
  • If any issue is NOT "Release Pending": end the workflow with status = "Not all issues are release pending" and reschedule_in = -1.

• Any other status: End the workflow with status = "status is <status>" and reschedule_in = -1.

Step 5: Try to Advance

1. Call get_erratum_transition_rules with erratum_id = the erratum ID (as string).
2. Parse the result as a transition rule set containing from_status, to_status, and a list of rules (each with name, outcome, and details).

Check target status matches:

• If to_status from the rules does not match the target status determined in Step 4:
  • Flag for attention with reason = "Next state is <to_status> instead of <target_status>".
  • End the workflow.

If ALL rules have outcome OK:

• If target is REL_PREP: proceed to Step 6 (Verify Product Listings).
• If target is QE:
  • Check whether state changes are allowed: the environment variable ERRATA_ALLOW_STATUS_CHANGES must be "true" (case-insensitive). If dry_run is true OR state changes are not allowed, skip the actual state change and log the reason.
  • Otherwise: call erratum_change_state with erratum_id and new_state = the target status.
  • End the workflow with status = "Moving to <target>, since all rules are OK" and reschedule_in = 0 (if target is QE) or -1 (otherwise).

If rules are blocking, identify all blocking rule names (those with outcome != OK):

Stagepush blocking:

1. Call get_erratum_stage_push_details with erratum_id.
2. Check the status field:
   • If null or COMPLETE: initiate a new push by calling erratum_push_to_stage. End with status = "Stage-pushing erratum <id> before moving to <target>" and reschedule_in = 1200.
   • If FAILED: flag for attention with reason = "Stage-push previously FAILED for erratum <id>, needs manual intervention before moving to <target>". End the workflow.
   • Any other status (in progress): end with status = "Stage-push already in progress (<status>) for erratum <id>, waiting for completion before moving to <target>" and reschedule_in = 1200.

Cat (CAT tests) blocking:

1. Call get_erratum_stage_push_details with erratum_id.
2. If push status is NOT COMPLETE: end with status describing the push status and reschedule_in = 1200.
3. If push status IS COMPLETE:
   • Check updated_at timestamp. If null: flag for attention with reason = "Cannot determine stage push completion time (no log timestamps available).".
   • Calculate time elapsed since updated_at (in UTC).
   • If elapsed > 3 hours: flag for attention with reason = "CAT tests didn't complete successfully after 3 hours".
   • If elapsed <= 3 hours: end with status = "Stage push completed for erratum <id>, waiting for CAT tests to complete before moving to <target>" and reschedule_in = 1200.

Securityalert blocking:

1. Call erratum_refresh_security_alerts with erratum_id.
2. End with status = "Refreshing security alerts for erratum <id> before moving to <target>" and reschedule_in = 1200.

Any other blocking rules:

• Collect all blocking rules and their details (name + details for each rule with outcome = BLOCK).
• Flag for attention with reason = "Transition to <target> is blocked by:\n<rule_name>: <rule_details>\n...".
• End the workflow.

Step 6: Verify Product Listings (REL_PREP only)

This step verifies that the package file lists of the current builds match those of previous erratum builds, catching unintentional changes before advancing to REL_PREP.

1. Call get_erratum_build_map with erratum_id. This returns a map of package names to builds (each with nvr and package_file_list).

2. For each package in the build map:

   a. Check if already verified: Call get_erratum with erratum_id and full=true to get comments. Search comments for the magic string ymir-product-listings-checked(<nvr>) where <nvr> is the current build's NVR. If found, skip this package.

   b. Find previous erratum: Call get_previous_erratum with erratum_id and package_name = the package name.

   c. If a previous erratum exists:

   • Call get_erratum_build_map for the previous erratum ID.
   • Compare the package_file_list of the current build against the same package in the previous build map.
   • Compose a verification comment:

     ymir-product-listings-checked(<current_nvr>)
     
     Compared the file lists for <current_nvr> to the file lists for
     <previous_nvr> in https://errata.engineering.redhat.com/advisory/<previous_erratum_id> -
     

     • If lists match: append "the same subpackages are shipped to each variant. Proceeding with the errata workflow."
     • If lists differ: append the differences (old and new file lists as JSON) and note "Flagging for human attention.". Track this package as a mismatch.
   • Call erratum_add_comment with the verification comment.

   d. If no previous erratum exists:

   • Call erratum_add_comment with:

     ymir-product-listings-checked(<current_nvr>)
     
     No previous erratum for this package - no need to check package file list change.
     

3. After processing all packages:

   • If any mismatches were found: flag for attention with reason = "The package file lists of this build don't match all of their previous builds - mismatch packages: [<packages>].\nSee erratum comments for details.". End the workflow.
   • If no mismatches: advance to REL_PREP using the same state-change logic as Step 5 (check ERRATA_ALLOW_STATUS_CHANGES and dry_run). End with status = "Moving to REL_PREP, since all rules are OK" and reschedule_in = -1.

Output Schema

The final output must be a JSON object:

{
    "status": "Description of what happened during the workflow run",
    "reschedule_in": -1
}

reschedule_in Values

• -1: Do not reschedule — terminal state (flagged for attention, no action needed, not all issues ready, or successfully advanced to REL_PREP)
• 0: Reschedule immediately — workflow should be re-run (e.g., after advancing to QE, the workflow should re-run to check if REL_PREP is possible)
• 1200: Reschedule in 20 minutes — waiting for stage push, CAT tests, or security alert refresh
