cliare
Black-box CLI measurement that emits evidence-backed shape files for AI agent-readiness.
CLIARE tackles a real pain point: agents guessing CLI commands. Its runtime-evidence approach beats doc scraping, but it's niche. Adopt it if you ship a CLI and want CI gates on agent-readiness; skip it if you need GUI or real-time dashboards. For a broader automation ecosystem, consider tools like Anthropic's Claude Code or OpenAI's Codex CLI, but for measuring your own CLI's agent compatibility, CLIARE is unique in its evidence-first method.

Skip CLIARE if you need a GUI, real-time monitoring, or cloud dashboards, or if you don't distribute a CLI (e.g., libraries only).
CLIARE is free, but you may need to invest time in learning Rust/Cargo for installation and usage.
CLIARE is free under Apache 2.0, making it accessible to all. Unlike commercial agent-readiness tools (e.g., some AI testing platforms), there's no per-seat or per-run cost. For maintainers, this is a low-risk way to adopt evidence-based CLI measurement without budget approval.
In short
cliare — Black-box CLI measurement that emits evidence-backed shape files for AI agent-readiness. Best for Maintainers of CLI tools, Agent harness developers, Security reviewers. Free to use.

About cliare
CLIARE is an open-source Rust CLI that measures a released binary as a black box to make your command-line interface legible to AI agents. It runs help, version, invalid-input, output-mode, and discovered command probes within a bounded traversal budget, recording runtime evidence such as exit status, stdout/stderr, timing, and side-effect deltas. From that evidence, it infers command shape—rows, flags, operands, output contracts, and preconditions—and emits versioned artifacts like command-index.json, shape.json, scorecards, and an evidence.jsonl proof log. This turns agent-readiness into an implementation queue: maintainers see exactly where agents lack evidence due to missing help, unclear grammar, or unsafe discovery, and harness developers get a reliable command surface before execution.
Behind the Verdict
CLIARE fills a genuine gap: a deterministic, black-box method to assess how well agents can use your CLI. Unlike doc scraping tools that infer from stale documentation, CLIARE probes the actual binary, capturing runtime evidence (exit status, stdout, timing, side-effects) and emits structured shape files (command-index.json, shape.json, evidence.jsonl, scorecard.json). This evidence-first approach makes agent-readiness measurable and actionable. For maintainers, the CI scorecards prevent regressions in discovery, grammar, parsing, recovery, and safety. For harness developers, the shape files reduce trial-and-error by providing known command routes and preconditions. However, CLIARE is command-line-only and requires Rust/Cargo comfort; there's no GUI or cloud dashboard. Its community is small, and it doesn't fix issues or integrate with specific agent frameworks—it's purely a measurement tool. For large enterprises with complex CLIs, the bounded traversal budget may limit depth. But for CLI maintainers serious about agent compatibility, CLIARE offers a unique, evidence-based solution.

Real-world workflow fit
Concrete scenarios for the personas cliare actually fits — and what changes day-one when you adopt it.
You want to ensure your CLI doesn't regress in agent-readiness between releases.
Outcome: Add CLIARE to CI with a scorecard gate. Each commit runs probes, emits scorecard.json, and fails if scores drop, catching missing help or unsafe discovery early.
You're building an agent that executes CLI commands and needs reliable command shapes.
Outcome: Run CLIARE on the target binary, then load command-index.json into your harness. Your agent routes user intents to correct commands without trial-and-error, using known preconditions and output contracts.
You need to verify that a CLI's help and version probes don't have unintended side effects.
Outcome: Review evidence.jsonl to trace each probe's side-effect deltas, ensuring safe behavior before approving agent execution.
Use Cases
- Measure a CLI binary to produce a command shape file for agent harness consumption.
- Integrate CLIARE into CI pipelines to gate releases based on agent-readiness scorecards.
- Identify missing help, unclear grammar, or unsafe probes in a CLI to prioritize fixes.
- Ship command-index.json and shape.json alongside each release to enable agent routing.
- Compare different CLI versions to detect drift in command surface and output contracts.
Limitations
- CLIARE is an open-source Rust CLI tool for measuring command-line binaries as a black box.
- It requires comfort with the command line and Rust/Cargo for installation.
- It measures but does not fix issues or integrate with specific agent frameworks.
- Its community is small and support is community-driven.
