Gauge CLI

by Gauge cli in Agent observability & evals

withgauge.com · who's behind it

Gauge CLI runs real coding agents (Claude Code, Codex, Pi, OpenCode) against your skills, CLIs, SDKs, MCP servers and docs in Docker, records where they get stuck, and lets your agent test fixes before release.

Best for Teams that build skills, CLIs, SDKs or MCP servers and want to see where coding agents get stuck with them, and to test fixes before release.

Is this your product? Claim it to see how agents find it: lookups through the API, MCP and letme, the comparisons it's in, and what people search for in Evals. Free, and it never changes the grade. Or verify it, or log in if it's already claimed.

Assessment. An open-source CLI that measures how coding agents get on with your product and checks fixes before you ship them, locally in Docker with no account. It's young and pre-1.0, collects anonymous command usage by default with a documented opt-out, and hosted runs need credits.

From our research 4 facts checked against the vendor's pages
Surface graded
The open-source CLI, read from a clone of github.com/gauge-sh/gauge-cli on 6 November 2026: the README, cli/README.md, cli/package.json, the changelog, workflows and tags. Hosted Gauge's pages and pricing weren't read. Nothing was installed or run
Local and hosted
Local runs use Docker and your agent credentials, with results in a private SQLite database that your coding agent analyses. Hosted Gauge adds managed compute, automated judging, native binaries, website previews, authenticated MCP servers and APIs, scheduled measurements and GitHub PR checks, on workspace credits
Releases
CLI 0.23.0 (20 October), 0.24.0 (22 October), 0.25.0 and 0.25.1 (27 October), 0.26.0 (28 October), 0.27.0 (2 November) and 0.28.0 (4 November) 2026, plus runtime, gateway and adapter packages
Telemetry
On by default for the installed CLI: command name, timestamp, CLI version and a random installation ID, excluding arguments, prompts, file contents and account identifiers. Off with gauge telemetry disable or GAUGE_TELEMETRY_DISABLED=1

Facts verified 6 November 2026 from vendor docs, repositories and package registries. JSON · Markdown

Strengths

  • Runs Claude Code, Codex, Pi and OpenCode in fresh Docker sessions against working-tree or pre-release versions
  • Local mode needs no Gauge account, only your existing agent credentials
  • Dated changelog with six releases in about two weeks
  • Instructions bundled in the CLI for coding agents, and -o json on read commands
  • CI runs checks on every push and pull request

Weaknesses

  • Collects anonymous command usage by default, with an opt-out
  • Pre-1.0 and about two weeks old in this repository
  • Docs, authenticated MCP servers and authenticated APIs need hosted Gauge and credits
  • Hosted credit prices weren't found on the pages read

Before you call it notes for agents

  1. npm install -g @withgauge/cli, then gauge local runtime pull and gauge init --local in the project
  2. Run gauge install-skill so your coding agent finds the CLI's own instructions
  3. Set GAUGE_TELEMETRY_DISABLED=1 in CI if you don't want command usage collected
  4. Rebuild and pack an npm CLI or SDK before rerunning, so test sessions get the new tarball
  5. Keep .gauge/ private; it holds measurements and analyses

Terms and privacy, as read

Terms of service none to read

TL;DR Nothing is hosted by the vendor, so there are no terms of service to read. The MIT licence stands in and the check scores in full.

Privacy policy none to read

TL;DR Nothing is hosted by the vendor, so there is no privacy policy to read and the check isn't scored.

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.

Not looked up: RDAP isn't requested under the 1 November 2026 rules.

The npm package's author is Gauge <support@withgauge.com>, its homepage agents.withgauge.com, and its repository field points at gauge-sh/gauge-cli. The licence names Gauge.

Hosted Gauge's terms and privacy weren't read, and security.txt wasn't checked.

Checked 2026-11-06 against the vendor's own pages and the domain registry. Provenance is half of Transparency & trust.

Notable

  • Discussed on Hacker News on 5 November 2026. The repository's first commit is 20 October 2026, importing an existing CLI at 0.23.0 source
  • Finds problems such as interactive commands that block an agent, deprecated patterns an agent reaches for, and skills that go unused, then reruns cases against pre-release artifacts to check a fix source
  • Collects command usage by default (command name, timestamp, version and a random install ID, no arguments or prompts), disabled with gauge telemetry disable or GAUGE_TELEMETRY_DISABLED=1 source
  • Six CLI releases in October and November 2026, from 0.23.0 on 20 October to 0.28.0 on 4 November, each in a dated changelog source

Weight is the published weight, and the figure under it is that category's share of the 100 points in this run. A pending category has no score and adds nothing. What changes when it's scored.

Score history no moves since it was graded

  1. Graded 60.4 C methodology v0.7

Fix list 13 items, the biggest gain first

Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Gauge CLI. A fix counts at the next check, once it's public.

What we couldn't check

  • Competitor note: Gauge runs agents against a product to find where they get stuck, close to Anchor Terminal's checks and audits. The listing-check rule names LocalGhost and letme for the competitor procedure, not the audits, so it was graded by one reader. The founder may want the competitor procedure and a disclosure
  • unchecked: hosted Gauge's pricing, terms, privacy and docs at docs.withgauge.com, and GitHub issues

Probe metrics

Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The pollers record uptime for hosted endpoints as they run, and that doesn't change the score either.

Pricing & changes

Freemium Freemium The CLI and local mode are free and MIT-licensed; agent usage is billed by your provider or subscription. Hosted Gauge runs on workspace credits, whose prices weren't read (checked 2026-11-06).

For the vendor

Is this your product? Link to this page from your own site or README, then tell us where. It shows people and agents that the listing is yours and that you know it's here. It never changes a grade, rank or review.

    It counts on a page on withgauge.com or one of its subdomains, or the README at the root of github.com/gauge-sh/gauge-cli.

  2. Tell us where it is

    We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.

Agents send the same to POST /api/v1/verify as {"slug": "gauge-cli", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
