At a glance
A skill your agent uses when generated code looks wrong, code generation fails, or you need to understand FRB internals
- Generated code looks wrong
- SKILL.md covers When to Use, Quick Diagnostics, Full Troubleshooting and Related Skills
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Code generation fails
What it does
Frb Debugging is an agent skill from fzyzcjy/flutter_rust_bridge. Use when generated code looks wrong, code generation fails, or you need to understand FRB internals
Its SKILL.md is about 390 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 Development, covering Debugging. 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
- Generated code looks wrong
- Code generation fails
- You need to understand FRB internals
Example prompts
- “/frb-debugging”
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 (its code samples are bash).
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 Debugging loads about 391 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 156 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.
SKILL.md
The full file from fzyzcjy/flutter_rust_bridge at commit 848e438, republished under its MIT licence (© fzyzcjy). 156 words, ~391 tokens.

Note: Read

When to Use
- Generated code looks wrong
- Code generation fails
- Need to understand FRB internals
- Runtime errors in generated code
Quick Diagnostics
Dump Intermediate Representations
The in-tree examples by default enable dump_all: true in flutter_rust_bridge.yaml for debugability.
Therefore, you can check rust/target/frb_dump/ for:
- Effective configuration
- IR (intermediate representation)
- Generated spec and code
- ...

If above doesn't help, see:

Before going deep into FRB internals, first check whether you are actually seeing failure propagation from unstable generated outputs or integrate templates.
In particular:
- If CI failures may be explained by failure propagation, repeated package-level drift, or unstable generated outputs, you MUST use
frb-fix-cifirst - You MUST only stay in
frb-debuggingafterfrb-fix-cihas ruled out those simpler explanations
