Local analytics dashboard for Claude Code. No cloud, no telemetry.
SaferSkills independently audited cc-lens (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

cc-lens CLI
Local analytics dashboard for Claude Code. No cloud, no telemetry, no API key, just your ~/.claude/ data, visualized.
npx cc-lensThe CLI finds a free local port, starts the dashboard, and opens it in your browser.
[!NOTE] cc-lens 0.4.0 is out
>
Adds Insights, budgets, team adoption, terminal digest, Wrapped, and expanded project docs.

Run directly with npx:
npx cc-lensOn first run, cc-lens prepares a small runtime cache in ~/.cc-lens/. After that, launches are faster.

Import is preview-only right now. It shows which sessions are new or already present, but it does not write merged data back into ~/.claude/, to avoid corrupting live Claude Code files.
By default, cc-lens reads ~/.claude/. To point it at another Claude Code config directory, set CLAUDE_CONFIG_DIR:
# Default profile
npx cc-lens
# Work profile
CLAUDE_CONFIG_DIR=~/.claude-work npx cc-lensOn Windows PowerShell:
$env:CLAUDE_CONFIG_DIR="C:\Users\you\.claude-work"; npx cc-lensThe active config directory is shown in the CLI banner on launch.
npx cc-lens [options]| Option | Default | Description |
|---|---|---|
--host <host> | 127.0.0.1 | Address to bind. Loopback only by default. Set 0.0.0.0 to expose the dashboard on your LAN. Also settable with the CC_LENS_HOST env var. |
--port <port> | 3000 | Port to listen on. Auto-increments if the port is taken. Also settable with the PORT env var. |
--help, -h | Print usage and exit. | |
--version, -v | Print the version and exit. |
The dashboard serves your private Claude Code history, so it binds to loopback (127.0.0.1) by default. cc-lens does not read the shell's HOSTNAME variable, so it works the same on WSL, containers, and CI. Override the host only if you understand the exposure.
# Bind to a fixed port
npx cc-lens --port 4000
# Expose on the local network (opt-in)
npx cc-lens --host 0.0.0.0There are also cc-lens push and cc-lens digest subcommands for team mode; see Team mode.

Claude Code Lens runs locally and reads files from your machine. It does not require a login, API key, hosted backend, or telemetry service. Your Claude Code history stays on your computer.
Claude Code stores token counts and model identifiers, not final billing totals. cc-lens estimates cost using the pricing table in lib/pricing.ts. If provider pricing changes, update that file to keep estimates current.
To override or add rates without editing source, create ~/.cc-lens/pricing.json. Entries are merged over the defaults, so you can override a single model or add new ones. Values are in dollars per million tokens:
{
"claude-opus-4-8": { "input": 5.0, "output": 25.0, "cacheWrite": 6.25, "cacheRead": 0.5 }
