pip-token: Instructions file for Claude Code

CLAUDE.md

pip-token CLAUDE.md is an instructions file for Claude Code from studiozedward/pip-token. It costs 689 tokens per session, scanned A, original, MIT.

Project conventions for pip-token, a VS Code extension that tracks Claude Code token usage in a Fallout Pip-Boy-style interface. VS Code is a code editor, and the extension stores usage data locally in SQLite, a small embedded database.

In plain words
What is it for?
Use them when developing, testing, packaging, documenting, or debugging the pip-token VS Code extension.
Why use it?
They keep the extension’s build, tests, architecture, file locations, branching, and commit style consistent. They also make clear that the extension does not make network calls.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is studiozedward/pip-token's own configuration. It tells Claude Code how to work on pip-token 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 pip-token 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

pip-token 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.

Pip-Token — Project Conventions

A VS Code extension that helps Claude Code users track their token usage with a Fallout Pip-Boy aesthetic.

Tech stack

TypeScript, VS Code Extension API, SQLite (better-sqlite3), plain HTML/CSS in the webview. No frontend frameworks. No chart libraries. No network calls.

Commands

  • npm install — install dependencies
  • npm run build — compile and bundle with esbuild
  • npm run watch — dev mode
  • npm test — run Vitest tests
  • npm run package — build .vsix
  • F5 in VS Code — launch the extension in a development host

Branching and commits

  • main is always shippable
  • Feature branches off main, named feat/short-description or fix/short-description
  • Squash-merge into main via PR
  • Conventional Commits: feat: ..., fix: ..., docs: ..., refactor: ..., test: ..., chore: ...

Where things live

  • Product spec: docs/DESIGN.md (authoritative)
  • Screenshots: mockups/screenshots/*.png (current state of the extension)
  • Terminology: docs/GLOSSARY.md
  • Architecture: docs/ARCHITECTURE.md
  • Decisions made and why: docs/decisions/
  • Lessons learned during build: LESSONS.md — read this before tackling areas marked as "previously problematic"

Subdirectory CLAUDE.md files

Pip-Token uses a distributed CLAUDE.md pattern. When working in src/parsing/, src/webview/, src/data/, src/domain/, or test/, also read the local CLAUDE.md in that directory — it contains conventions specific to that subsystem.

Session identity

A "session" in Pip-Token maps 1:1 to a Claude Code sessionId. Clearing context in Claude Code starts a new session with a new ID — this is intentional, not a bug. Context window utilisation and cache state are per-session and cannot be meaningfully merged across sessions. The "All Projects" aggregate on LIVE/SESSION sums token counts from the turns table across all active sessions (not from window counters, which break across rate-limit boundaries and resyncs).

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.
