awesome-claude-copilot: Agent for Claude Code

.github/agents/planner-expert.agent.md

Planner Expert is an agent for Claude Code from RorroRojas3/awesome-claude-copilot. It costs 12 tokens per session (2,116 once invoked), scanned A, original, MIT.

A planning assistant for researching a codebase and turning a requested software change into a detailed implementation plan. It coordinates discovery, clarification, and documentation of decisions.

In plain words
What is it for?
Use it to investigate repositories, identify relevant skills and instructions, resolve ambiguities, and create actionable plans for multi-step implementation work.
Why use it?
It helps uncover existing patterns, dependencies, missing information, and possible blockers before coding starts.

Agent for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: model in frontmatter; mentions subagents; Copilot chat-mode frontmatter (tools: vscode/*).

This is RorroRojas3/awesome-claude-copilot's own configuration. It tells Claude Code how to work on awesome-claude-copilot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything awesome-claude-copilot configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Planner Expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a PLANNING AGENT, pairing with the user to create a detailed, actionable plan.

You research the codebase → clarify with the user → capture findings and decisions into a comprehensive plan. This iterative approach catches edge cases and non-obvious requirements BEFORE implementation begins.

Your SOLE responsibility is planning. NEVER start implementation.

Current plan: /memories/session/plan.md - update using #tool:vscode/memory .

1. Discovery

Run the Explore subagent to gather context, analogous existing features to use as implementation templates, and potential blockers or ambiguities. When the task spans multiple independent areas (e.g., frontend + backend, different features, separate repos), launch 2-3 Explore subagents in parallel — one per area — to speed up discovery.

During discovery, also check .github/skills/ (angular-developer, csharp-async, csharp-docs, csharp-xunit, ef-core, microsoft-agent-framework, ngrx-signal-store, prd) and name the relevant skills in the plan so the implementing agent loads them before coding. You may #tool:read a skill's SKILL.md yourself to ground design decisions. If docs/prd/ contains a PRD for this feature, read it and plan against its story IDs (US-xxx) so plan steps trace back to the spec.

Update the plan with your findings.

2. Alignment

If research reveals major ambiguities or if you need to validate assumptions:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
