Use when writing or reviewing AI agent configs, system prompts, or tool definitions (JSON/YAML/Python) and you need to catch ambiguous tool descriptions, missing stop conditions, schema/description mismatches, or embedded prompts before they reach runtime. Deterministic static analysis, no LLM or network calls.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# LintLang

LintLang statically analyzes the natural-language instructions that control AI
agents — system prompts, tool descriptions, and configs — catching ambiguous
tools, missing limits, and mixed output formats before they reach an agent
at runtime. It is zero-LLM: deterministic pattern and structural checks only,
no model calls, no telemetry, no network access.

## Use it for

- Linting tool descriptions before agents start choosing between them
  (detects pairs like `get_user_info` / `fetch_user_data` with no
  distinguishing term — check `H1.6`)
- Checking prompts and configs for missing stop conditions, unbounded
  retries, and schema/description mismatches
- Running a zero-LLM CI gate over YAML, JSON, prompt text, and Python source
- Scanning `.py` files for embedded prompts and uncalibrated thresholds
  (detectors `P1`/`P2`)
- Preflighting one present instruction plus explicit typed context before a
  host sends it to a model

## Do not use it for

- Runtime evaluation of a live agent
- Dynamic agent testing or behavioral benchmarking
- Proving an agent is safe in production
- Retrieving preferences from history, deciding truth, or rewriting/sending

How to install

The exact contents, by fingerprint
mdr add hermes-labs-ai/lintlang/lintlang@sha256:08c550015dbebfa9

The line at the top of this page pins the label git:20260929.4e1b4f0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
