# vscode-copilot-customization output preview
## PART A: Task fit
- Use case: > Use when this capability is needed. Use this matrix to recommend the right customization type. Always start here. | Scenario | Best choice | | ------------------------------------------------------------------- | ---------------------------------- | runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more..
- Inputs: target material, constraints, expected output, and acceptance criteria.
- Evidence boundary: follow “Decision Matrix / Quick decision flow / 1. Custom Instructions” 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 this capability is needed. Use this matrix to recommend the right customization type. Always start here. | Scenario | Best choice | | ------------------------------------------------------------------- | ---------------------------------- | runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more.”.
- **02** When the source has headings, the agent prioritizes “Decision Matrix / Quick decision flow / 1. Custom Instructions” 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, run shell commands; mostly runs locally; usually needs no extra API key.
## Running Rules
- read files, write/modify files, run shell commands; 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 mentions slash commands such as `/init`, `/create-instruction`, `/create-prompt`, `/create-agent`, `/create-skill`; use them first when your agent supports command triggers.
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, run shell commands.
Start with a small task and check whether the result follows “Decision Matrix / Quick decision flow / 1. Custom Instructions”. 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.

# vscode-copilot-customization
## When to use
- > Use when this capability is needed. Use this matrix to recommend the right customization type. Always start here. |…
- 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 “Decision Matrix / Quick decision flow / 1. Custom Instructions” and keep inference separate from source facts.
- read files, write/modify files, run shell commands; 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.

Decision Matrix
Use this matrix to recommend the right customization type. Always start here.
| Scenario | Best choice |
|---|---|
| Project-wide coding standards, always active | copilot-instructions.md |
| Rules only for specific file types / folders | *.instructions.md with applyTo |
| Works with multiple AI agents (Claude, Copilot, etc.) | AGENTS.md |
| Reusable task you invoke manually in chat | Prompt file (.prompt.md) |
| Specialized workflow with tool restrictions or model choice | Custom agent (.agent.md) |
| Portable capability reusable across projects + CLI + cloud agents | Agent skill (SKILL.md) |
| Auto-run commands at agent lifecycle points (format, lint, enforce) | Hook (.json) |
| Bundle multiple customizations to share or distribute | Agent plugin (plugin.json) |
Quick decision flow
Do you want it ON automatically for every request?
├─ YES → Instructions (.instructions.md / copilot-instructions.md / AGENTS.md)
└─ NO, I invoke it manually →
Does it need persistent persona, tool restrictions, or model choice?
├─ YES → Custom Agent (.agent.md)
└─ NO →
Is it a reusable multi-agent portable capability?
├─ YES → Agent Skill (SKILL.md)
└─ NO → Prompt File (.prompt.md)
Do you want to run shell commands around agent actions?
└─ YES → Hook (hooks/*.json)
Do you want to bundle everything for distribution?
└─ YES → Agent Plugin (plugin.json)
1. Custom Instructions
Always-on context and rules. Stored in .github/copilot-instructions.md (workspace-wide), AGENTS.md (multi-agent), or *.instructions.md (file-scoped via applyTo glob).
Read references/instructions.md when asked to create, write, or configure custom instructions.
2. Prompt Files
Reusable task templates invoked manually via / slash command. Stored in .github/prompts/*.prompt.md.
Read references/prompt-files.md when asked to create a prompt file or reusable chat task.
3. Custom Agents
Specialized Copilot persona with tool whitelist, model choice, and optional handoffs. Stored in .github/agents/*.agent.md.
Read references/custom-agents.md when asked to create a custom agent or chat mode.
4. Agent Skills
Portable, progressive-loading capabilities that work across VS Code, Copilot CLI, and cloud agents. Stored in .github/skills/<name>/SKILL.md.
Read references/agent-skills.md when asked to create a skill or when the user asks about SKILL.md format, frontmatter fields, or skill best practices.
5. Hooks
Shell commands triggered at agent lifecycle events (PostToolUse, Stop, etc.). Stored in .github/hooks/*.json.
Read references/hooks.md when asked to create a hook, set up auto-formatting, or run commands around agent actions.
6. Agent Plugins
Bundle skills, agents, hooks, and MCP servers for distribution. Defined in plugin.json.
Read references/plugins.md when asked to create, publish, or install an agent plugin.
