Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00218 | $0.02682 |
| Opus 5.5 | $0.00087 | $0.01073 |
| Sonnet 5.5 | $0.00044 | $0.00536 |
| Haiku 4.5 | $0.00022 | $0.00268 |
Grade A, and why
discover-feature-flags scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

discover-feature-flags is a skill published in the GitHub repository harness/harness-skills (117 stars, last pushed yesterday), licensed Apache-2.0. It adds 218 tokens to every session and 2,682 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-07.

foundry-config-setup
Resolve missing setup caused by a hardcoded Foundry project endpoint or model in a sample. Use when a sample fails because it uses a placeholder/hardcoded projectendpoint (for example "https://your-project.services.ai.azure.com") or a hardcoded model instead of reading them from the environment.

Drive Omnigent the way a user does and prove a behavior with recorded evidence, using an isolated server, runner, and mock model plus a feature map of every user entry point.
