Suggest awesome GitHub Copilot agents
Compare the repository's existing custom agents and current project needs with the GitHub awesome-copilot agent catalog, then recommend missing or outdated .agent.md files without installing or updating anything until the user explicitly asks.
When to invoke
- "Suggest awesome GitHub Copilot custom agents for this repo."
- "Which awesome-copilot agents should we add?"
- "Compare our .github/agents with awesome-copilot."
- "Find outdated local custom agents."
- "Update this custom agent from awesome-copilot."
Prerequisites and context
Use web access to read the awesome-copilot catalog and raw agent files. The catalog is at https://github.com/github/awesome-copilot/blob/main/docs/README.agents.md; agent files are under https://github.com/github/awesome-copilot/tree/main/agents and raw files follow https://raw.githubusercontent.com/github/awesome-copilot/main/agents/{filename}.
Local custom agents live in .github/agents/ as *.agent.md files. Read YAML frontmatter from local files to extract description and tool configuration.
Analysis procedure
- Fetch the available custom agent list and descriptions from
https://github.com/github/awesome-copilot/blob/main/docs/README.agents.md.
- List every local
.github/agents/*.agent.md file.
- Read local frontmatter and body to inventory descriptions, tools, and instructions.
- For each local filename that appears likely to exist upstream, fetch
https://raw.githubusercontent.com/github/awesome-copilot/main/agents/{filename}.
- Compare full local and remote content, including frontmatter, tools array, and body.
- Classify local agents as up-to-date, outdated, or local-only.
- Analyze repository context: languages (
.cs, .js, .py, and others), frameworks such as ASP.NET, React, Azure usage, project type, documentation needs, recent chat context, feature requests, code review patterns, and workflow requirements.
- Match catalog agents to gaps that would add value and are not already covered.
- Present a table only; include links to awesome-copilot agent files and similar local agents.
- Await a user request before installing or updating any agent.
Relevance criteria
| Signal |
Evidence to collect |
How it affects suggestions |
| Language |
File extensions, package manifests, build files |
Prefer agents that operate on actual stacks in the repo. |
| Framework |
ASP.NET, React, Azure, test frameworks, deployment files |
Suggest framework-specific agents only with matching evidence. |
| Project type |
Web app, API, library, tool, docs site |
Match agents to recurring tasks and operational needs. |
| Documentation |
README, specs, ADRs, docs folders |
Suggest documentation or architecture agents when docs work exists. |
| Chat history |
Recent pain points, feature requests, review themes |
Prioritize what the user is actively working on. |
| Existing coverage |
.github/agents/*.agent.md descriptions |
Avoid duplicates unless the local agent is outdated. |
Version comparison rules
| Comparison result |
Condition |
Output status |
| Up-to-date |
Entire local file exactly matches remote |
Already installed and up-to-date |
| Outdated |
Same filename exists remotely but content differs |
Installed but outdated (update available) |
| Not installed |
Remote catalog agent has no matching local file |
Not installed in repo |
| Local-only |
Local file has no matching remote |
Mention only when relevant to duplicate avoidance. |
For outdated agents, document specific differences: frontmatter description, tools array additions/removals/renames, or body content updates. The historical example principal-software-engineer.agent.md can differ because remote uses 'web/fetch' while local uses 'fetch'.
Installation and update rules
Do not install or update during the suggestion pass. When the user later requests specific agents:
- Download new agents into
.github/agents/.
- Replace outdated agents entirely with the latest remote version.
- Preserve file location in
.github/agents/.
- Do not adjust the downloaded content.
- Track progress while downloading or updating multiple assets.
Examples
Use links like these in the table when relevant:
| Awesome-Copilot Custom Agent |
Description |
Already Installed |
Similar Local Custom Agent |
Suggestion Rationale |
| amplitude-experiment-implementation.agent.md |
This custom agent uses Amplitude's MCP tools to deploy new experiments inside of Amplitude, enabling seamless variant testing capabilities and rollout of product features |
No |
None |
Would enhance experimentation capabilities within the product |
| launchdarkly-flag-cleanup.agent.md |
Feature flag cleanup agent for LaunchDarkly |
Yes |
launchdarkly-flag-cleanup.agent.md |
Already covered by existing LaunchDarkly custom agents |
| principal-software-engineer.agent.md |
Provide principal-level software engineering guidance with focus on engineering excellence, technical leadership, and pragmatic implementation. |
Outdated |
principal-software-engineer.agent.md |
Tools configuration differs: remote uses 'web/fetch' vs local 'fetch' - update recommended |
Gotchas
- Do not install during recommendation: the first output is analysis only; wait for explicit user direction.
- Do not suggest duplicates: if a similar local agent already covers the need, report that instead of recommending another copy.
- Do not compare descriptions only: tools and body changes can make an agent outdated even when descriptions match.
- Do not reference prompt files: this skill is about custom agent
.agent.md files only.
Legacy VS Code instructions may mention #fetch, #runInTerminal, #todos, fetch, githubRepo, and curl; in this CLI skill, use available web or shell capabilities instead and do not expose unsupported tool names as frontmatter. The control words AWAIT, INSTALL, UPDATE, UNLESS, DIRECTED, and Download/Update mean wait for explicit user direction before changing local agents.
