Codelens-AI: Instructions file for Claude Code

CLAUDE.md

Codelens-AI CLAUDE.md is an instructions file for Claude Code, Codex from Akshat2634/Codelens-AI. It costs 4,204 tokens per session, scanned A, original, MIT.

A project guide for Codelens AI, a command-line tool that estimates the return on AI coding agents by comparing their token use with Git commits. It reads session records from several coding tools and presents the results in a local dashboard.

In plain words
What is it for?
Use it when modifying, testing, or extending Codelens AI. It covers session-file parsing, Git history analysis, the dashboard, command-line behavior, and serving reports through MCP.
Why use it?
It gives agents the project overview, supported data sources, technology choices, and special output rules for its MCP server. That context helps changes fit the existing data flow and prevents non-JSON text from corrupting tool communication.

Instructions file for Claude CodeCodex

Written for Codex and Claude Code: reads ~/.codex or $CODEX_HOME, but also the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is Akshat2634/Codelens-AI's own configuration. It tells Claude Code and Codex how to work on Codelens-AI 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 Codelens-AI 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

Codelens-AI 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.

Project Overview

Codelens AI (codelens-ai on npm) is a CLI tool that measures ROI from AI coding agents by correlating token usage with git commit output. It parses Claude Code session files (~/.claude/projects/), OpenAI Codex CLI rollout files (~/.codex/sessions/), and GitHub Copilot sessions from the standalone CLI (~/.copilot/session-state/) plus official VS Code Chat/agent mode (workspaceStorage/*/chatSessions/), analyzes git history, and serves an interactive dashboard at http://localhost:3457 with per-agent source tabs (All Agents / Claude Code / OpenAI Codex / GitHub Copilot).

Version: 0.9.0 License: MIT npm package: codelens-ai (alias: claude-roi)

Tech Stack

  • Runtime: Node.js >= 22.12, ES modules ("type": "module")
  • Backend: Express.js 5.0.0
  • CLI: Commander.js 13.0.0
  • MCP: @modelcontextprotocol/sdk — codelens-ai mcp serves the reports as MCP tools over stdio (src/mcp.js); stdout carries only JSON-RPC, so all progress output must go to stderr there
  • Frontend: Single-file HTML (src/dashboard.html) with vanilla JS + Chart.js 4.5.1. The UMD bundle is committed at src/vendor/chart.umd.min.js and served at /vendor/chart.umd.min.js — no CDN, works offline, and does not depend on chart.js being resolvable at the user's runtime (npx caches have shipped partial node_modules). chart.js is a devDependency; refresh the vendored copy with npm run vendor:chart after upgrading it (also runs on prepublishOnly).
  • Testing: node --test unit + server-route tests (tests/unit/), a packaging smoke test (npm run test:package — packs → clean-installs → boots → asserts the dashboard and vendored chart serve), and Playwright (E2E)
  • Styling: Inline CSS design tokens, "warm-ink instrument panel" (dark) / "warm-paper ledger" (light) theme; fonts: Bricolage Grotesque (display), Instrument Sans (body), IBM Plex Mono (data). Chart palette is CVD-validated per theme — don't swap chart hues casually.

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.
