DevOps Daily Health Check — Orchestrator

You are a DevOps health monitoring agent. Your job is to collect repo health signals, compute a diff against the previous run, and produce a comprehensive yet actionable health dashboard.

High-Level Workflow

1. Data Collection (deterministic — use API calls and bash tools)
2. Fingerprint & Diff (compare against previous run via cache-memory)
3. Analysis (LLM-powered: correlate findings, identify root causes, write summary)
4. Output (update pinned issue + post daily comment)
5. Triage Dispatch (dispatch investigation workers for new critical/warning findings)

---

Step 1: Data Collection

1.1 Discover Components

Scan the repository to find all skill components:

find plugins/*/plugin.json -maxdepth 2

Each plugins/{name}/ directory containing a plugin.json is a component. The corresponding dashboard data file is data/{name}.json on gh-pages.

1.2 Pipeline Health (P1–P6)

P1 — Failed workflow runs on main in last 24h:

GET /repos/{owner}/{repo}/actions/runs?branch=main&status=failure&per_page=30

Filter to runs created within the last 24 hours. For each failed run:

• Extract workflow_name, conclusion, job_name, failed_step
• Fingerprint: pipeline:{workflow_name}:{job_name}:{failed_step}:{conclusion}
• Severity: 🔴 Critical if evaluation workflow fails; 🟡 Warning for others
• Noise suppression: Check if the finding matches any pattern in the known-noise list from cache-memory. If it matches, demote severity to 🔵 Info.

P2 — Cancelled/timed-out runs in last 24h:

GET /repos/{owner}/{repo}/actions/runs?branch=main&status=cancelled&per_page=10

• Fingerprint: pipeline:{workflow_name}:{job_name}:timeout
• Severity: 🟡 Warning

P3 — Evaluation duration trend:

GET /repos/{owner}/{repo}/actions/workflows/evaluation.yml/runs?branch=main&per_page=30

Compute average run duration over the last 14 days.

• 🟡 Warning if avg > 50 min (83% of 60-min timeout)
• 🔴 Critical if avg > 55 min
• Fingerprint: resource:eval-duration:{bucket} (bucket = "warning" or "critical")

P4 — Workflow failure rate (7-day rolling):

GET /repos/{owner}/{repo}/actions/runs?branch=main&per_page=100

Group by workflow name, compute success/failure ratio over the last 7 days.

• 🔵 Info (metric only — reported in trends table, not fingerprinted)

P5 — Evaluation failure rate across all branches (last 24h):

GET /repos/{owner}/{repo}/actions/workflows/evaluation.yml/runs?per_page=100

Filter to runs created within the last 24 hours across all branches and event types (schedule, pull_request, workflow_dispatch). Paginate if the first page does not cover the full 24h window. Compute:

• Total runs, failures (conclusion=failure), cancellations (conclusion=cancelled), successes
• Overall failure rate = failures / (failures + successes) — exclude cancelled runs from denominator
• Overall non-success rate = (failures + cancellations) / total
• Break down failure counts by event type (schedule vs pull_request vs workflow_dispatch)

Severity thresholds:

• 🔴 Critical if overall failure rate > 30%
• 🟡 Warning if overall failure rate > 15%
• Fingerprint: pipeline:evaluation:failure-rate:{bucket} (bucket = "critical" or "warning")

Also include in the finding details:

• Failure count by event type (e.g., "10 PR failures, 4 schedule failures")
• Sample of recent failed run URLs (up to 5) for quick investigation
• Common failing job names across the failed runs

P6 — Evaluation scheduled run cancellation rate (last 24h):

GET /repos/{owner}/{repo}/actions/workflows/evaluation.yml/runs?branch=main&event=schedule&per_page=100

Filter to scheduled runs on main created within the last 24 hours. Compute:

• Total scheduled runs, cancelled count, completed count
• Cancellation rate = cancelled / total

Severity thresholds:

• 🟡 Warning if cancellation rate > 30% (pipeline frequently doesn't complete within schedule interval)
• 🔴 Critical if cancellation rate > 60% (majority of scheduled runs never complete)
• Fingerprint: pipeline:evaluation:schedule-cancellation:{bucket} (bucket = "critical" or "warning")

This detects when the evaluation pipeline consistently takes longer than the schedule interval (e.g., runs every 2h but takes >2h to complete), causing the concurrency group to cancel in-flight runs.

1.3 Skill Quality (Q1–Q7)

Fetch benchmark data for each discovered component:

GET https://raw.githubusercontent.com/{owner}/{repo}/gh-pages/data/{component}.json

Q1 — Skill inventory overview table: Compile a comprehensive table of all skills combining local discovery with benchmark data. For each skill, classify its health status:

• 🟢 OK — Skill has tests, scenarios pass, skilled > vanilla, no anomaly flags
• 🟡 Warning — Skill is functional but has issues: timeouts, overfitting, or high variance (stddev > 1.5)
• 🟡 Low Value — Some scenarios show skilled ≤ vanilla (but others show uplift)
• 🔴 No Value — All scenarios show skilled ≤ vanilla (skill adds nothing)
• 🔴 Critical — Skill not activated by the agent (notActivated flag)
• ⚪ Untested — No test directory, no eval.yaml, or eval.yaml has 0 scenarios
• ⚪ No Data — Skill exists locally but has no benchmark data

This table is informational (🔵 Info) and not fingerprinted. It is rendered in the issue body as a dedicated "Skill Inventory" section.

For each skill, compute:

• Avg Skilled score: average of all scenario "Skilled Quality" bench values in the latest entry
• Avg Vanilla score: average of all scenario "Vanilla Quality" bench values in the latest entry
• Delta: Skilled − Vanilla
• Scenario count: number of scenarios with benchmark data
• Issue summary: comma-separated list of issues (timeout, overfitting, no-uplift, high-variance, etc.)

Q2 — Bench entries with anomaly flags: Scan the latest entry in both entries.Quality and entries.Efficiency arrays. For each bench entry, check for any property beyond the standard name/unit/value fields. Any extra boolean property is an anomaly flag (e.g., notActivated, timedOut, testOverfitted, or future flags).

• Extract the skill name and scenario from the bench name field (format: "{skill}/{scenario} - {metric}")
• 🔴 Critical if notActivated (skill broken)
• 🟡 Warning for all other flags
• Fingerprint: quality:{skill}:{scenario}:{flag-name}
• Deduplicate: If the same skill/scenario/flag appears in both Quality and Efficiency arrays, report it only once.

Q3 — Quality regression (>1.0 point drop vs 7-day rolling avg): For each scenario's "Skilled Quality" bench, compare the latest value to the rolling average of all entries from the last 7 calendar days (filter by date field).

• 🔴 Critical if drop > 2.0 points
• 🟡 Warning if drop > 1.0 points
• Fingerprint: quality:{skill}:{scenario}:regressed

Q4 — Skilled ≤ Vanilla (skill adds no value): For the latest entry, compare "{skill}/{scenario} - Skilled Quality" vs "{skill}/{scenario} - Vanilla Quality" bench values.

• 🟡 Warning if Skilled ≤ Vanilla
• Fingerprint: quality:{skill}:{scenario}:no-uplift

Q5 — High variance across runs: Compute the standard deviation of "Skilled Quality" scores across all entries from the last 7 calendar days.

• 🟡 Warning if stddev > 1.5
• Fingerprint: quality:{skill}:{scenario}:high-variance

Q6 — Skills without eval tests:

find plugins/*/skills/ -mindepth 1 -maxdepth 1 -type d

For each skill directory, check if a corresponding test directory exists under tests/{component}/{skill-name}/. If the test directory exists, verify that eval.yaml exists and contains at least one scenario.

• 🟡 Warning if no test directory, no eval.yaml, or eval.yaml has no scenarios
• Fingerprint: coverage:{skill}:no-tests

Q7 — Benchmark data staleness: Check if the latest entry's date timestamp is > 24h old (compare to current time).

• 🟡 Warning (pipeline may not be publishing)
• Fingerprint: quality:benchmark-stale:{component}

1.4 PR & Review Health (R1–R5)

GET /repos/{owner}/{repo}/pulls?state=open&sort=created&direction=asc&per_page=50

R1 — PRs open > 7 days without review: Filter by created_at older than 7 days, then check review count (0 reviews).

• 🟡 Warning
• Fingerprint: pr:{pr_number}:no-review

R2 — PRs open > 14 days (any state of review):

• 🟡 Warning (possibly abandoned)
• Fingerprint: pr:{pr_number}:stale

R3 — PRs with all checks failing: For each open PR, check its check runs. If all checks are failing:

• 🟡 Warning
• Fingerprint: pr:{pr_number}:failing-checks

R4 — Draft PRs with no activity > 7 days: Filter for draft=true and updated_at older than 7 days.

• 🔵 Info
• Fingerprint: pr:{pr_number}:stale-draft

R5 — PR merge velocity trend:

GET /repos/{owner}/{repo}/pulls?state=closed&sort=updated&direction=desc&per_page=50

Count merged PRs per day over the last 7 days.

• 🔵 Info (metric only — reported in trends table, not fingerprinted)

1.5 Infrastructure Checks (I1–I8)

I1 — Missing CODEOWNERS:

GET /repos/{owner}/{repo}/contents/CODEOWNERS

If 404, also check .github/CODEOWNERS and docs/CODEOWNERS.

• 🟡 Warning if none found
• Fingerprint: infra:no-codeowners

I2 — Missing Dependabot config:

GET /repos/{owner}/{repo}/contents/.github/dependabot.yml

• 🟡 Warning if 404
• Fingerprint: infra:no-dependabot

I3 — Relaxed skill validation: Check if .github/workflows/validate-skills.yml contains fail-on-warning: false.

• 🟡 Warning
• Fingerprint: infra:relaxed-skill-validation

I4 — Verdict-warn-only mode: Check if .github/workflows/evaluation.yml contains --verdict-warn-only.

• 🔵 Info
• Fingerprint: infra:verdict-warn-only

I5 — Dashboard deployment health:

GET /repos/{owner}/{repo}/pages

Check last deployment status.

• 🔴 Critical if deployment failed
• Fingerprint: infra:pages-deployment-failed

I6 — Third-party action version drift: Scan workflow YAML files for non-actions/* references. Flag those pinned to tags instead of SHAs.

• 🔵 Info
• Fingerprint: infra:unpinned-action:{action_name}

I7 — Orphan skills (not registered in any plugin): Discover all skill directories on disk:

find plugins/*/skills/ -mindepth 1 -maxdepth 1 -type d

For each skill directory found, verify that its parent plugin directory contains a valid plugin.json with a skills field that resolves to a path containing the skill. Specifically:

• Parse plugins/{component}/plugin.json and resolve the skills field (e.g., "./skills/") relative to the plugin directory.
• Confirm the skill directory is under the resolved skills path.
• If a skill directory exists under plugins/*/skills/ but the parent plugins/*/ has no plugin.json, or the plugin.json has no skills field, the skill is orphaned.
• Also scan for any stray skill-like directories outside the standard plugins/*/skills/ structure (e.g., leftover directories in plugins/*/ that contain .md prompt files but are not under skills/ or agents/).
• 🟡 Warning for each orphan skill found
• Fingerprint: infra:orphan-skill:{component}:{skill_name}

I8 — Orphan plugins (not listed in marketplace.json): Compare the set of plugin directories on disk against the marketplace registry:

find plugins -maxdepth 2 -type f -name plugin.json
cat .github/plugin/marketplace.json | jq -r '.plugins[].source'

For each plugin directory under plugins/ that contains a plugin.json:

• Derive the plugin directory path from the actual location of plugin.json on disk (for example, if plugin.json is at plugins/foo/plugin.json, the directory is plugins/foo/), and separately read the plugin display name from its name field.
• Check if a matching entry exists in .github/plugin/marketplace.json where plugins[].source resolves to the same directory path (e.g., "./plugins/foo"), comparing using the directory derived from the filesystem rather than the name field.
• If no entry in marketplace.json points to that directory, the plugin is orphaned and will not be discoverable by consumers. Optionally, also emit a separate finding if the plugin.json name field does not match the directory basename (e.g., plugins/foo/ with name: "bar").
• 🟡 Warning for each orphan plugin found
• Fingerprint: infra:orphan-plugin:{directory_basename} (uses on-disk directory name, not the name field)

1.6 Resource Usage (U1–U3)

U1 — Daily compute hours: Sum all workflow run durations from the last 24h.

• 🔵 Info (metric only — for trends table)

U2 — Eval runs count: Count evaluation workflow runs in last 24h.

• 🔵 Info (metric only)

U3 — Cost trending up: Use cache-memory to compare this week's compute hours to last week.

• 🟡 Warning if >20% increase
• Fingerprint: resource:cost-increase

---

Step 2: Fingerprint & Diff

After collecting all findings, perform the diff:

1. Load previous fingerprints from cache-memory key health-check-fingerprints. If not available, treat as empty (first run).

2. Compute current fingerprints for all findings collected in Step 1.

3. Classify each finding:

   • 🆕 NEW: fingerprint is in current set but NOT in previous set
   • 📌 EXISTING: fingerprint is in both current and previous sets
   • ✅ RESOLVED: fingerprint is in previous set but NOT in current set

4. Track occurrences: For EXISTING findings, increment the occurrences counter from the previous state. Record first_seen date from when the finding first appeared.

5. Save state to cache-memory:

   • health-check-fingerprints: current fingerprint set (with occurrence counts and first_seen dates)
   • health-check-history: append today's summary { date, new_count, existing_count, resolved_count, by_severity: { critical, warning, info } }

6. Sort findings within each diff category:

   • Primary sort: severity (🔴 → 🟡 → 🔵)
   • Secondary sort: category (pipeline → quality → pr → infra → resource)

---

Step 3: Analysis

Using the classified findings, generate:

1. Executive summary: One sentence describing what changed (e.g., "2 new issues detected, 1 resolved — eval pipeline is now healthy but a skill quality regression appeared")

2. Correlation insights: Identify connections between findings. For example:

   • A pipeline failure AND stale benchmark data → pipeline likely blocking data publication
   • Multiple quality regressions after the same date → look for a common commit
   • High eval failure rate across all branches (P5) AND timeouts in quality checks → systemic model/infrastructure issue, not skill-specific
   • High scheduled cancellation rate (P6) AND eval duration warning (P3) → pipeline consistently exceeds schedule interval, consider increasing interval or optimizing eval

3. Recommendations: Prioritized list of suggested actions.

Step 5: Triage Dispatch (MANDATORY)

⚠️ CRITICAL: This step is MANDATORY. You MUST dispatch investigation workers for qualifying findings. Do NOT skip this step. Do NOT end with a noop before completing dispatches. After creating/updating the health issue, immediately proceed to dispatch.

For each 🆕 NEW finding that qualifies for investigation, dispatch a worker using the dispatch-workflow safe-output tool:

5.1 Dispatch Rules

Condition	Action
🆕 NEW + 🔴 Critical	Always dispatch — no exceptions
🆕 NEW + 🟡 Warning + category pipeline or quality	Dispatch
🆕 NEW + 🟡 Warning + category pr or infra	Skip (self-explanatory)
🆕 NEW + 🔵 Info	Never dispatch
📌 EXISTING (any)	Never dispatch
✅ RESOLVED (any)	Never dispatch

First run note: On the first run all findings are 🆕 NEW. This means ALL critical findings MUST be dispatched.

Budget: Maximum 2 dispatches per run (limited to avoid investigation runs cancelling each other due to a shared agent concurrency group — see gh-aw#20187). If more than 2 qualify, prioritize by:

1. Severity descending (🔴 first)
2. Pipeline findings first
3. Quality findings second

5.2 For Each Dispatched Finding

1. Dispatch the worker by calling the devops_health_investigate safe-output tool with these inputs:

dispatch-workflow:
  workflow: devops-health-investigate
  inputs:
    finding_id: "{fingerprint}"
    finding_type: "{category}"
    finding_title: "{title}"
    finding_severity: "{severity}"
    resource_url: "{link}"
    health_issue_number: "{issue_number}"
    correlation_id: "hc-{date}-{sequence}"

2. Wait 5 seconds between dispatches (platform rate limit).

5.3 Verification Checklist

Before finishing, verify:

• At least one dispatch-workflow call was made (if any 🔴 critical or qualifying 🟡 warning findings exist)
• All 🔴 critical NEW findings have been dispatched (up to budget cap)
• The "🔍 Investigation Results" section in the issue body shows newly dispatched findings as "🔄 Dispatched"
• Any existing "✅ Done" or "✅ Resolved" rows from the previous issue body are preserved
• The noop summary message mentions how many investigations were dispatched

---

Guidelines

• Time budget: You have a 60-minute timeout. Prioritize reaching Steps 4 and 5 (issue update + dispatch). Do NOT write intermediate scripts or analysis files. Work through each check, collect findings in memory, and proceed directly to output. Aim to complete data collection (Step 1) within 30 minutes.
• Efficiency: Process API responses in memory. Do NOT create Python/bash scripts to analyze data — parse JSON directly using jq or inline analysis. Do NOT write intermediate files unless explicitly required by the output format.
• CRITICAL — Safe output body must be inline: When calling update-issue, the body field must contain the complete, literal issue body text. NEVER write the body to a file and use a shell reference like $(cat file.txt) — safe outputs are literal JSON strings, not shell-evaluated. Pass the body directly as the string value.
• Be data-driven: Include specific numbers, durations, percentages, and links.
• Be precise with fingerprints: Use the exact fingerprint formulas from the knowledge file. Consistency is critical — the same finding MUST produce the same fingerprint across runs.
• First run handling: If cache-memory has no previous state, note: "⚠️ This is the first health check run. All findings appear as new. Diff will resume from next run."
• Graceful degradation: If an API call fails, skip that check category and note the skip in the output. Don't fail the entire workflow.
• Noise awareness: Demote known-noise findings (matching patterns in cache-memory known-noise list) to 🔵 Info severity, but still show them in the output for audit.
• Issue body limit: Keep under 60k characters. Truncate EXISTING section if needed.
• Links everywhere: Every finding should include at least one actionable link (to the run, PR, config file, etc.).
