What is DebugPilot CLAUDE.md?

A project instruction document for DebugPilot, a VS Code extension that provides a debug MCP server. VS Code is a code editor, and debugging means running code while inspecting its behavior and output.

Installing dependencies, building and type-checking the extension, running tests, understanding its source files, and preparing releases.

It gives contributors the project's commands, architecture, conventions, and release steps in one place.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00624	$0.00624
Opus 5.5	$0.00250	$0.00250
Sonnet 5.5	$0.00125	$0.00125
Haiku 4.5	$0.00062	$0.00062

Security

Grade A, and why

DebugPilot CLAUDE.md 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 2mo 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.

DebugPilot — VS Code Debug MCP Server

Quick Reference

pnpm install              # Install dependencies
pnpm run build            # esbuild → dist/extension.js
pnpm run build:check      # tsc --noEmit (type check only)
pnpm run test             # vitest run
pnpm run build:watch      # esbuild watch mode

Architecture

Single-package VS Code extension. The MCP server runs inside the extension host process — no IPC needed.

src/extension.ts — activate/deactivate entry point
src/server.ts — DebugMcpServer wrapping McpServer + stdio transport
src/debug-adapter.ts — IDebugAdapter implementation using vscode.debug.* APIs
src/session-manager.ts — tracks debug sessions + console buffers
src/console-buffer.ts — ring buffer for console output
src/source-reader.ts — reads source lines around breakpoint
src/tools/*.ts — one file per MCP tool
src/types.ts — IDebugAdapter interface + shared types
src/constants.ts — tool names, defaults

Release Checklist

When releasing a new version:

Bump version in package.json and src/server.ts (MCP server version field)
Update CHANGELOG.md — add a new section at the top with the version, date, and all changes (Added/Changed/Fixed/Removed). Every user-facing change must be listed.
Run full build + tests: npx tsc --noEmit && node esbuild.config.mjs && npx vitest run
Package: npx vsce package --no-dependencies
Publish: VSCE_PAT=$(az account get-access-token --resource 499b84ac-1321-427f-aa17-267ca6975798 --query accessToken -o tsv) npx vsce publish --pre-release --no-dependencies

Conventions

All tools go in src/tools/ — one file per tool, registered via src/tools/index.ts
IDebugAdapter is the testability boundary — mock it in tests, never mock vscode.debug directly in tool tests
Use vscode.debug.activeDebugSession.customRequest() for DAP protocol calls
Console buffer is per-session, managed by SessionManager
vscode is external in esbuild — never bundle it
Tests use vitest with vscode mock at test/mocks/vscode.ts

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.
