# flags output preview
## PART A: Task fit
- Use case: Use when you need to check feature flag states, compare channels, or debug why a feature behaves differently across release channels. | Option | Purpose | |--------|---------| | (none) | Show all flags across all channels | | --diff <ch1> <ch2> | Compare flags between channels | | --cleanup | Show flags grouped by cleanup status | runs entirely locally. W….
- Inputs: target material, constraints, expected output, and acceptance criteria.
- Evidence boundary: follow “Options / Channels / Legend” and do not present inference as author intent.
## PART B: Execution result
- **01** The card summarizes the use case; runtime output centers on “Use when you need to check feature flag states, compare channels, or debug why a feature behaves differently across release channels. | Option | Purpose | |--------|---------| | (none) | Show all flags across all channels | | --diff <ch1> <ch2> | Compare flags between channels | | --cleanup | Show flags grouped by cleanup status | runs entirely locally. W…”.
- **02** When the source has headings, the agent prioritizes “Options / Channels / Legend” so the result follows the author’s structure.
- **03** Typical output includes task judgment, concrete steps, required commands or file edits, validation, and follow-up options.
- **04** Risk context follows the fingerprint: read files, write/modify files; mostly runs locally; usually needs no extra API key.
## Running Rules
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding scope.
- Return the result, validation criteria, and next iteration options. The source does not require a stable slash command. After installation, invoke the skill by name and describe the task.
Name target files or source material, expected output, forbidden changes, and whether network or shell access is allowed. Permission fingerprint: read files, write/modify files.
Start with a small task and check whether the result follows “Options / Channels / Legend”. Inspect diffs, logs, previews, or tests before expanding scope.
Confirm the final output includes a concrete result, evidence, and next action. If it stays generic, tighten inputs, boundaries, and acceptance criteria.

# flags
## When to use
- Use when you need to check feature flag states, compare channels, or debug why a feature behaves differently across re…
- Use it when the task has clear inputs, repeatable steps, and validation criteria.
## What to provide
- Target material, scope, expected result, and forbidden changes.
- Whether network, commands, file writes, or external services are allowed.
## Execution rules
- Organize steps around “Options / Channels / Legend” and keep inference separate from source facts.
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding the task.
## Output requirements
- Return the deliverable, key evidence, validation method, and next action.
- Mark missing information as unknown; do not invent commands, platforms, or dependencies. The author source anchors workflow facts; repository files anchor sources and commands; Fluxly only adds fit, limitations, and quality judgment.
