Overview

Audit Harness FME feature flags across a project. Read-only; never writes. Four modes: inventory (list flags with metadata), rollout-report (per-env rollout state with stalled-promotion detection across a confirmed env sequence), stale-audit (find flags with no impressions via lastImpressionAt), pattern-search (find flags whose rule conditions structurally match an attribute name, matcher type, literal value, segment reference, or flag dependency — not a text grep). Use when asked to "show me all flags", "which flags are stale", "what flags are rolled out", "flag inventory", "flag health", "cleanup candidates", "find flags targeting segment X", "which flags depend on flag Y", or "find flags with rule matching attribute Z". Do not use for single-flag deep dive (explain-flag), creating flags (create-feature-flag), updating targeting (update-flag-targeting), archiving/deleting (manage-flag-lifecycle), pipeline rollouts (fme-pipeline), or code removal (cleanup-feature-flags).

Discover Feature Flags

Audit Harness FME feature flags across a project: list all flags with metadata, show rollout status per environment, find stale flags, or search rule conditions structurally. Read-only. Never writes. Related: explain-flag (single flag), cleanup-feature-flags (code removal), manage-flag-lifecycle (archive).

Tools

Works through the Harness MCP server or the Harness CLI; names are from tool-map.md.

Operation	MCP	CLI
List environments	`harness_list` · `fme_environment` · `filters: { offset: 0, limit: 100 }` · `compact: false`	`harness list fme_environment --json`
List rollout statuses	`harness_list` · `fme_rollout_status` · `filters: { offset: 0, limit: 100 }` · `compact: false`	`harness list rollout_status --json`
List flags	`harness_list` · `fme_feature_flag` · `size: 50` · `filters: { name?, tags?, rollout_status_id?, offset? }` · `compact: false`	`harness list feature_flag [--search <name>] [--status <ACTIVE\|ARCHIVED>] --limit 50 --json`
Get flag	`harness_get` · `fme_feature_flag` · `params.feature_flag_name`	`harness get feature_flag <name> --json`
List definitions	`harness_list` · `fme_feature_flag_definition` · `params.feature_flag_name` · `filters: { offset: 0, limit: 100 }` · `compact: false`	`harness list feature_flag:definition <name> --json`
List segments	`harness_list` · `fme_segment` · `filters: { segment_type, status?, offset: 0, limit: 100 }` · `compact: false`	`harness list segment --segment-type <STANDARD\|LARGE\|RULE_BASED> --json`; cover ACTIVE and ARCHIVED with declared status filters
List experiments	`harness_list` · `fme_experiment` · `filters: { parent_type: "FEATURE_FLAG", parent_name, status: ["ACTIVE", "PAUSED"], offset: 0, limit: 100 }` · `compact: false`	`harness list experiment --parent-type FEATURE_FLAG --parent-name <name> --status ACTIVE --json`, then again with `--status PAUSED`

For each filter: apply it server-side if declared by the installed transport (verify via --help); otherwise fetch the complete inventory and filter client-side. Paginate every list to completion per tool-map.md.

Output

Fixed shape per mode:

Rollout report: | Flag | <Env 1>* | <Env 2>* | … | Promotion | Notes | (production envs *; cells use actual treatment names/percentages, killed→<fallback>, targeted, limited, missing, unknown or archived). Promotion: stalled?, ahead, ok, behind (no alert), divergence, both killed, missing, unknown, intended ✓, not comparable, archived, or — for neutral-only. Label each hop in multi-env chains; see promotion-check.md.

Summary: counts per class, truncation line if paginated, hand-offs to sibling skills.

Instructions

Phase 1: Establish scope

Follow scope-establishment.md. Restate: Working in org=..., project=....

Phase 2: Collect inputs

Ask only for missing items relevant to the user's goal:

Mode: inventory (default) / rollout-report / stale-audit / pattern-search. Infer from prompt.
Filters: name substring, tag, rollout status name, traffic type, status (ACTIVE / ARCHIVED), owner — apply server-side where declared; client-side otherwise on the complete inventory.
Environment subset (rollout-report / stale-audit / pattern-search): default all.
Staleness threshold (stale-audit only): default 30 days per concepts.md.
Pattern-search predicates: collect per rule-patterns.md §Clarification.
Promotion check: both the environment sequence and intended target treatment must be confirmed before promotion classifications; otherwise show neutral differences. See promotion-check.md §Inputs.

Phase 3: List environments and rollout statuses

List environments through every page: ID → { name, isProduction }. Default display order: non-production first, production last. The environment sequence for promotion checks must be confirmed explicitly by the user — do not derive order from isProduction alone. List rollout statuses through every page: name → ID. Apply pagination completeness checks from tool-map.md.

Phase 4: List flags

Apply declared server-side filters (name, tags, rollout_status_id); handle remaining filters client-side on the complete inventory. Page through every offset to a short page. Inventory mode stops here. Skip to Phase 6.

Cost guard (rollout-report / stale-audit / pattern-search): If >50 flags after filtering, STOP: "This will fetch N paginated definition inventories. Narrow by tag, name, rollout status, or status, or confirm to proceed." See tool-map.md.

Phase 5: List and classify definitions

For each flag, list definitions (all pages, filters.limit: 100, advance offset). Failed or skipped pages → incomplete; never label unseen definitions missing.

Rollout-report: Classify each (flag, env) cell per concepts.md: killed → no definition → allocation < 100 → rules/targets present → defaultRule shape. For the confirmed promotion sequence, apply promotion-check.md to produce the Promotion column. Archived flags (global status: ARCHIVED): include in table as archived row; exclude from stalled/divergence alerts.

Stale-audit: Buckets per concepts.md §Staleness. impressions.lastImpressionAt: ISO-8601 (null = never evaluated; absent = unknown). For ready/caution candidates, run the experiment check (ACTIVE and PAUSED) per write-safety.md. Next Step: hand off to cleanup-feature-flags (code) or manage-flag-lifecycle (archive).

Pattern-search: Apply structural rule matching per rule-patterns.md. To resolve a segment name to its type, list that segment type's metadata via List segments (one complete paginated inventory per type; reuse across all flags). Killed flag definitions: scan rules but annotate matches inactive (killed). Archived flags included by the requested status filter: retain structural matches and annotate inactive (archived); do not imply live exposure.

Phase 6: Output

Present the fixed table for the mode. Summary counts per class or bucket. Pagination alone is not truncation: report truncation/incomplete coverage only if the inventory was not finished.

Hand-offs: Single-flag → explain-flag. Cleanup candidate → cleanup-feature-flags. Archive → manage-flag-lifecycle. Update targeting → update-flag-targeting. Pipeline rollout → fme-pipeline.

Examples

"Show me all feature flags" — Inventory mode.
"Which flags are stale?" — Stale-audit mode, default 30 days.
"Where is new-checkout-flow rolled out?" — Route to explain-flag for one flag.
"List flags with tag payments" — Inventory mode, filter by tag.
"Find cleanup candidates" — Stale-audit mode, bucket stale + fully rolled out.
"Show rollout status for all flags in production" — Rollout-report mode, environment subset.
"Find flags that target segment beta-users (STANDARD)" — Pattern-search, segment reference predicate.
"Which flags depend on flag-A?" — Pattern-search, flag dependency predicate (IN_SPLIT).
"Are flags stalled between staging and prod?" — Rollout-report with promotion check; requires confirmed env IDs, sequence, and intended treatment per flag.

Performance Notes

Inventory mode: One paginated flag inventory; no definitions.
Rollout-report / stale-audit / pattern-search: One paginated definition inventory per flag. Cost guard at 50 flags; narrow first by tag, name, rollout status, or status.
Stale-audit experiment check: Run only for ready/caution candidates, not every flag. Paginate ACTIVE and PAUSED separately.
Pattern-search segment resolution: List each needed segment type once; reuse across all flags.
Parallelizing definition reads: Batch list-definitions calls where the client supports parallel calls.
Pagination: See tool-map.md.

Troubleshooting

Issue	Fix
`impressions.lastImpressionAt` absent	Treat as `unknown` bucket; never infer "unused"
Definitions call fails with 404	Re-list flags; confirm exact name (case-sensitive)
"Too many requests" or timeout	Narrow by tag, rollout status, or name; or process in batches
Pattern-search returns unparsed rows	See rule-patterns.md §Unparsed Shapes
Promotion check cannot compare	Confirm env IDs, sequence, and intended treatment per promotion-check.md

## Output

Fixed shape per mode:

**Inventory:** `| Flag | Traffic type | Status | Rollout status | Tags | Owners | Created | Updated |`

**Rollout report:** `| Flag | <Env 1>* | <Env 2>* | … | Promotion | Notes |` (production envs `*`; cells use actual treatment names/percentages, `killed→<fallback>`, `targeted`, `limited`, `missing`, `unknown` or `archived`). Promotion: `stalled?`, `ahead`, `ok`, `behind (no alert)`, `divergence`, `both killed`, `missing`, `unknown`, `intended ✓`, `not comparable`, `archived`, or `—` for neutral-only. Label each hop in multi-env chains; see [promotion-check.md](references/promotion-check.md).

**Stale audit:** `| Flag | Bucket | Last Impression Per Env | Config | Next Step |` (buckets: stale / active / unknown / never evaluated; verdicts: ready / caution / blocked)

**Pattern search:** `| Flag | Env | Rule # | Combiner | Negated | Matcher type | Predicate match | Status | Notes |` (coverage footer: matched N / no-match M / unparsed P / unchecked U; see [rule-patterns.md](references/rule-patterns.md))

Summary: counts per class, truncation line if paginated, hand-offs to sibling skills.

Use when asked to \"show me all flags\", \"which flags are stale\", \"what flags are rolled out\", \"flag inventory\", \"flag health\", \"cleanup candidates\", \"find flags targeting segment X\", \"which flags depend on flag Y\", or \"find flags with rule matching attribute Z\". Do not use for single-flag deep dive (explain-flag), creating flags (create-feature-flag), updating targeting (update-flag-targeting), archiving/deleting (manage-flag-lifecycle), pipeline rollouts (fme-pipeline), or code removal (cleanup-feature-flags).
