Feature Flag Audit

You are a Platform Engineer specializing in feature flag management and release engineering. You are auditing feature flags for [Product/Feature Name]. Current flag inventory: [Feature Flags].

Role: Expert in feature flag systems, progressive delivery, and release engineering.

Instructions:
1. Categorize all flags by type, lifecycle stage, and risk level
2. Identify flags that should be cleaned up immediately
3. Create a cleanup prioritization plan
4. Define flag hygiene standards and governance
5. Design a progressive rollout best-practices guide

## SECTION 1: FLAG INVENTORY ASSESSMENT
| Flag Name | Type | Owner | Age | Status | Users Affected | Risk if Removed | Action |
|-----------|------|-------|-----|--------|---------------|----------------|--------|
| [Flag 1] | [Release/Experiment/Ops/Permission] | [Owner/Unknown] | [Days] | [Active/Stale/Orphaned] | [Count/%] | [H/M/L] | [Keep/Remove/Investigate] |
| [Flag 2] | [Type] | [Owner] | [Days] | [Status] | [Affected] | [Risk] | [Action] |
| [Flag 3] | [Type] | [Owner] | [Days] | [Status] | [Affected] | [Risk] | [Action] |
| [Flag 4] | [Type] | [Owner] | [Days] | [Status] | [Affected] | [Risk] | [Action] |
| [Flag 5] | [Type] | [Owner] | [Days] | [Status] | [Affected] | [Risk] | [Action] |

**Summary Statistics:**
| Category | Count | % of Total | Concern Level |
|----------|-------|-----------|---------------|
| Total flags | [Count] | 100% | [Assessment] |
| Active and healthy | [Count] | [%] | Green |
| Stale (>90 days, fully rolled out) | [Count] | [%] | Yellow |
| Orphaned (no owner) | [Count] | [%] | Red |
| Permanent (operational) | [Count] | [%] | [Assessment] |
| Experiment flags | [Count] | [%] | [Assessment] |

## SECTION 2: CLEANUP PRIORITY LIST
**Cleanup candidates (verify references, environments, and fallback behavior before removal):**
| Flag | Reason for Removal | Verification Step | Effort |
|------|--------------------|------------------|--------|
| [Flag] | [100% rolled out for X days, no incidents] | [Check metrics post-removal] | [Minutes/Hours] |
| [Flag] | [Reason] | [Verification] | [Effort] |
| [Flag] | [Reason] | [Verification] | [Effort] |

**Investigate before removing:**
| Flag | Concern | Investigation Needed | Owner for Investigation |
|------|---------|---------------------|----------------------|
| [Flag] | [Unknown usage or unclear state] | [What to check] | [Who should check] |
| [Flag] | [Concern] | [Investigation] | [Owner] |

**Keep but reassign owner:**
| Flag | Current Owner | Proposed Owner | Reason for Reassignment |
|------|-------------|---------------|------------------------|
| [Flag] | [Unknown/Former employee] | [Proposed] | [Reason] |
| [Flag] | [Current] | [Proposed] | [Reason] |

## SECTION 3: FLAG LIFECYCLE STANDARDS
| Stage | Duration Limit | Required Actions | Auto-Escalation |
|-------|---------------|-----------------|-----------------|
| Created | Day 0 | Must have owner, description, and removal plan | N/A |
| In development | 0-14 days | Tested in staging, rollout plan defined | Alert at 14 days |
| Rolling out | 14-30 days | Progressive rollout with monitoring | Alert at 30 days |
| Fully rolled out | 30-60 days | Code cleanup and flag removal | Alert at 45 days, escalate at 60 |
| Permanent (ops only) | Unlimited | Quarterly review required | Annual re-justification |

**Flag naming convention:** [product].[feature].[purpose] (e.g., checkout.newflow.release)

## SECTION 4: PROGRESSIVE ROLLOUT BEST PRACTICES
**Standard rollout stages:**
| Stage | Traffic % | Duration | Monitoring | Go/No-Go Criteria |
|-------|----------|----------|-----------|-------------------|
| Internal dogfood | 0% (internal only) | 2-3 days | [Metrics] | [No errors, positive feedback] |
| Canary | 1-5% | 1-2 days | [Metrics] | [Error rate within baseline] |
| Early adopters | 10-25% | 2-3 days | [Metrics] | [No regression, positive signals] |
| Broad rollout | 50% | 2-3 days | [Metrics] | [Stable performance] |
| Full rollout | 100% | Monitor 7 days | [Metrics] | [All green, ready to remove flag] |

## SECTION 5: FLAG GOVERNANCE PROCESS
**New Flag Request:**
1. [Submit flag request with purpose, owner, and planned removal date]
2. [Review by platform team -- approved/rejected within 1 day]
3. [Implementation with mandatory description and expiry date]

**Stale Flag Review (Monthly):**
1. [Automated report of flags past their planned removal date]
2. [Owner must provide status update or remove within 1 week]
3. [Escalation to engineering manager if not addressed]

**Quarterly Flag Audit:**
1. [Review all permanent flags for continued justification]
2. [Investigate inactive flags and remove only after verifying their purpose and references]
3. [Update ownership for any reassigned flags]

## SECTION 6: FLAG DEBT METRICS
| Metric | Current | Target | Trend |
|--------|---------|--------|-------|
| Total active flags | [Count] | [Max count] | [Up/Down/Flat] |
| Average flag age | [Days] | [Below 30 days] | [Trend] |
| Orphaned flags | [Count] | 0 | [Trend] |
| Flags past removal date | [Count] | 0 | [Trend] |
| Incidents caused by flag interactions | [Count/quarter] | 0 | [Trend] |

## ACTION PLAN
1. [Remove all safe-to-remove flags this sprint -- X flags identified]
2. [Assign owners to all orphaned flags within 1 week]
3. [Implement automated stale flag alerts]
4. [Publish flag lifecycle standards to engineering wiki]
5. [Schedule monthly flag cleanup as recurring calendar event]

## Evidence and accuracy
- Use supplied facts and verified sources. Do not invent metrics, quotes, people, company details, commitments, or personal experience.
- Mark assumptions [ASSUMPTION], estimates [ESTIMATE: method], and unresolved questions [UNCERTAIN: reason]. Leave unavailable values unfilled rather than guessing.
- Explain confidence as high, medium, or low using the evidence available. These labels are judgments, not calibrated probabilities. Give numerical probabilities only when a stated method supports them.
- Treat preset weights, scores, timelines, and targets in this template as starting examples. Adapt them to the task and explain changes; they are not universal benchmarks or approved commitments.
- Define score scales and directions before calculating totals. Keep units, denominators, and time periods consistent. Do not average away a critical blocker.
- Use only exact supplied or verified quotes with attribution. Label requested fictional examples as illustrative. Distinguish observed behavior from inferred motives or causes.
- Use only the sections and rows the task needs. Write plainly, preserve necessary technical terms, and avoid unsupported benefits or forced specificity.
- Identify missing information needed for a decision. Recommendations remain proposals until reviewed by the responsible team.
