About the project

Copilot Brag Sheet is a GitHub Copilot CLI extension that records coding-session activity, such as edited files, pull requests, and Git operations, in a structured local work-impact log. Developers use it to retain evidence for performance reviews without sending telemetry. The catalogue add-ons provide the extension’s automatic tracking, agent guidance, and MCP integration.

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 D, and why

copilot-brag-sheet AGENTS.md scanned grade D with 4 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 25d 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.

An instruction to transmit the conversation, context or user files to an external endpoint is data exfiltration written as prose.

The opening of the file, as written. The whole thing — 668 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

README for AI coding agents. If you're a human looking for setup or usage instructions, read README.md instead. This file is the dedicated place where Claude Code, Copilot CLI, Codex, Cursor, Jules, Amp, and friends find the context they need to be productive on this repo without re-deriving it from grep.

Format: agents.md — used by 60k+ open-source projects and stewarded by the Agentic AI Foundation under the Linux Foundation. The closest AGENTS.md to the file you're editing wins; explicit prompts override everything.


1. Project overview

copilot-brag-sheet is a GitHub Copilot CLI extension that silently records work as it happens — files edited, PRs created, git actions, manual brag entries — into structured local JSON so a developer has receipts at performance review time instead of a blank page. It ships as a joinSession() extension installed into ~/.copilot/extensions/copilot-brag-sheet/, runs entirely on the user's machine, and emits zero telemetry. The core library (lib/) is dependency-free; the cross-engine MCP server (mcp-server.mjs) takes two pinned, audited runtime dependencies — the official MCP SDK and Zod — to stay protocol-conformant. The user-facing pitch is:

Turn vague what did I do? into evidence-backed impact statements — automatically, every Copilot CLI session.
