What it does
Frb Feature Flag is an agent skill from fzyzcjy/flutter_rust_bridge. Use when adding or testing flutterrustbridge feature flags, especially flags that require coverage for both enabled and disabled states or should have package-level config plus item-level [frb(...)] overrides.
Its SKILL.md is about 250 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Cross-platform mobile apps. It works with Rust and Flutter. The repository describes itself as: Flutter/Dart <- Rust binding generator, feature-rich, but seamless and simple. The licence is MIT.
When your agent uses it
- Testing flutterrustbridge feature flags
- Especially flags that require coverage for both enabled and disabled states
- Should have package-level config plus item-level [frb(...)] overrides
Example prompts
- “/frb-feature-flag”
What it can do on your machine
Read from SKILL.md and the folder at commit 848e438. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Frb Feature Flag loads about 248 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 107 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use when adding or testing flutter_rust_bridge feature flags, especially flags that require coverage for both enabled and disabled states or should have package-level config plus item-level #[frb(...)] overrides.
FRB Feature Flags
Use this skill when adding a feature flag, changing a feature flag, or writing coverage for a feature flag.
API Surface
For feature flags requiring coverage for both enabled and disabled states:
- Expose the flag in
flutter_rust_bridge.yaml. - Expose the flag in the command-line interface.
- Prefer adding an item-level
#[frb(...)]override when the behavior can reasonably be scoped to a Rust item.
Test Coverage
In frb_example/pure_dart, prefer tests that use the item-level #[frb(...)] override so enabled and disabled cases are both exercised in the same package.
Do not rely only on package-level config differences when both states can be covered clearly with item-level Rust APIs.
