Monitor Your Docs

Keep your docs truthful with automated snippet validation.

Mantis crawls your docs, README, LLMs.txt, quickstarts, API specs, and repo files, then validates snippets and cross-checks claims before docs drift reaches production.

What It Does

Built for fast-moving API teams

Core Features

Collect

Crawls docs plus README, AGENTS.md, LLMs.txt, quickstarts, and optional GitHub/OpenAPI sources.

Validate

Runs syntax/import/runtime checks and replacement suggestions for missing or deprecated packages.

Analyze

Applies DocPrism categories with optional LLM + Smart/Full RnR and constrained evidence filtering.

Gate

Ships CI/CD and CLI parity with conflict views (snippets, evidence, timeline, charts) to block stale releases.

How It Works

From URL to actionable fixes in minutes

Connect Sources

Add docs URL + optional repo and OpenAPI schema for ground-truth consistency checks.

Launch Pipeline

Mantis crawls, validates, extracts entities, and runs DocPrism/RnR analysis.

Review Evidence

Inspect inline diff, linked evidence cards, conflicts tab, and staleness timeline.

Ship with Guardrails

Use GitHub Action + CLI exit codes to fail builds before stale docs reach users.

Detection Coverage

Live Ruleset

Package and version staleness

Detects unresolvable packages and deprecated versions.

Critical

Broken CLI and API commands

Validates shell examples, flags incorrect flags and endpoint paths.

Warning

Cross-document contradictions

Flags README/API/quickstart disagreements with evidence pairs and categorization.

Advisory

Timeline and analytics drift

Tracks scan volume, error trends, language distribution, and entity drift across runs.

Trend

Sample Finding

NPM package no longer exists

Snippet

npm install -g @acme/legacy-cli

Status: 404 registry error

Suggested replacement: @acme/cli

CLI Example

Why Mantis

Dedicated pipeline vs one-off prompting

Capability	Mantis	DIY Claude / Script
Deterministic checks	Built-in (syntax, imports, registry)	Manual / not included
Token cost per run	Batched + cached, small models first	Full cost every invocation
CI/CD integration	One command, exit codes, PR comments	Custom scripts to maintain
Setup time	Under 2 minutes	Hours to days
Cross-doc consistency	Automatic entity extraction + conflict detection	N/A or manual comparison
Caching	Hash-based, skip unchanged snippets	Build your own
Repeatable results	Same input, same pass/fail, every run	Prompt variance across runs

A senior dev can build this. We're selling "don't build it, run it."
