david-vscode: Instructions file for Claude Code

CLAUDE.md

david-vscode CLAUDE.md is an instructions file for Claude Code from edwardyen724-g/david-vscode. It costs 2,524 tokens per session, scanned A, original, MIT.

Repository instructions for building and packaging David, a VS Code extension that coordinates multiple Claude Code agents. A `.vsix` file is an installable VS Code extension package.

In plain words
What is it for?
Use them when developing David, checking its TypeScript build, creating a `.vsix`, or installing the package in VS Code.
Why use it?
They give the coding agent the project context and commands needed to compile, test, package, and locally install the extension.

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

david-vscode 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 9d 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project: David — agent orchestration for Claude Code

A VS Code extension that runs multiple specialist claude subprocesses (one per agent) on a single project, coordinated by a planner+workers overseer. Provides scheduled jobs, a nightly memory-distillation dream cycle, a skills system, and portable agent templates.

Status (as of 2026-05-23): v0.1.0-rc1 is built. david-0.1.0-rc1.vsix is the most recent package. The current focus is shipping v0.1 to the VS Code Marketplace / Open VSX, then building v0.2+. Marketing is a separate effort.

Build, package, install

npm install                            # one-time
npm run compile                        # tsc -p . → out/
npm run watch                          # tsc -watch for active dev
npx tsc --noEmit -p .                  # typecheck-only

# Produce a .vsix:
npx @vscode/vsce package --allow-missing-repository --skip-license

# Local install:
code --install-extension ./david-<version>.vsix

# Publish (when Edward signs off — irreversible, public):
npx @vscode/vsce login edwardyen724    # one-time
npx @vscode/vsce publish               # uses package.json version
# or:
npx ovsx publish david-<version>.vsix -p <openvsx-token>

Manual debug: open this folder in VS Code, press F5 → "Run David (mock)" — boots an Extension Development Host with the mock seed. No real claude subprocess spawns unless you register a real folder via the welcome view.

No automated tests exist. v0.1 shipped on manual click-through QA + real-workspace smoke tests. If you propose adding tests, surface that as a real architectural choice (test runner, mocking strategy for node-pty/claude) — don't drop a vitest/jest scaffold unprompted.

Architecture — the non-obvious bits

The plugin is mostly a UI + spawner over a file-bus. All cross-agent state lives in ~/.david/workspaces/<slug>/. Re-spawning rehydrates from disk.

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.
