What it does
Feature Overview is an agent skill from skybrush-io/live. Write concise architecture overview documents for features. Use when creating or updating docs about feature structure, design rationale, extension points for agents and humans
Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: An open-source drone show and drone swarm ground control station GUI frontend. The licence is GPL-3.0.
When your agent uses it
- Updating docs about feature structure
- Design rationale
- Extension points for agents and humans
Example prompts
- “/feature-overview”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Study the actual implementation — diffs, current code, how things are wired. Understand the feature thoroughly before writing.
- Ask the user clarifying questions. Don't assume; don't guess. The user knows what the feature does and why decisions were made.
- Once you and the user have a shared understanding, write the overview.
- Trim aggressively. Every sentence must earn its place.
What it can do on your machine
Read from SKILL.md and the folder at commit e104a06. 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
Feature Overview loads about 704 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 369 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.

Feature overview documents
When to create one
When a feature spans multiple files and has non-obvious design decisions, relationships, or invariants that an agent working on related changes would need to understand but cannot easily discover by reading a single file
File
.agents/docs/<feature-slug>/overview.md
Purpose
Give agents the mental model — structure, relationships, rationale, invariants
Not a catalog of what each file contains
The goal is to save context and time: an agent reads this, then knows where to look and what to watch for
Content rules
Include
- Purpose — what problem the feature solves. One paragraph.
- Architecture at a glance — layers, components, their relationships. What depends on what. What knows about what.
- Key abstractions — concepts that span files, described in terms of their role and interactions, not their implementation.
- Design decisions and rationale — especially non-obvious ones: why two backends, why state lives outside Redux, why broadcast is deliberately unsupported on a path, etc.
- Invariants and gotchas — constraints that must hold (e.g. "resume callbacks must never enter Redux", "this slice is not persisted"). Things agents could break if they don't know.
- Extension points — patterns for adding new variants of the thing (new task type, new mass op, etc.). Brief, not tutorial.
- Deliberate gaps — what was intentionally left out and why (no cancellation, no persistence).
Show full SKILL.md (158 more words)Show less
Exclude
- Implementation details discoverable by reading one file (how a key is constructed, what a function returns)
- Copy-pasted code snippets
- File indexes / directory listings
- Consumer/UI component lists (unless a specific integration point is architecturally significant)
- Anything an agent can find with a quick grep or by reading the file referenced
Style
- Dense, no filler, ~80 lines is a good target
- Inline file references with concepts (e.g. "the active-operations Map in
actions/uav-test.ts") — agents shouldn't need to search for the file - Tables only for comparing alternatives or backends
- Headings for navigation, not hierarchy for its own sake
Process
- Study the actual implementation — diffs, current code, how things are wired. Understand the feature thoroughly before writing.
- Ask the user clarifying questions. Don't assume; don't guess. The user knows what the feature does and why decisions were made.
- Once you and the user have a shared understanding, write the overview.
- Trim aggressively. Every sentence must earn its place.
