doc-scannerScans for project documentation files (AGENTS.md, CLAUDE.md, GEMINI.md, COPILOT.md, CURSOR.md, WARP.md, and 15+ other formats) and synthesizes guidance.
Doc Scanner is an agent skill from aiskillstore/marketplace. Scans for project documentation files (AGENTS.md, CLAUDE.md, GEMINI.md, COPILOT.md, CURSOR.md, WARP.md, and 15+ other formats) and synthesizes guidance. Auto-activates when user asks to review, understand, or explore a codebase, when starting work in a new project, when asking about conventions or agents, or when documentation context would help. Can consolidate multiple platform docs into unified AGENTS.md.
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts, reference files and assets (for example `references/file-patterns.md`, `references/templates.md` and `skill-report.json`).
It sits in Agent Workflows, covering Agent instruction files. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
GlobReadWriteBashFrom allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/, which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Doc Scanner loads about 644 tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 197 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Glob, Read, Write, BashAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Doc Scanner fits situations like: explore a codebase; starting work in a new project; asking about conventions; documentation context would help.
Run `npx skills add aiskillstore/marketplace --skill doc-scanner -a claude-code`. Or copy the skill folder (skills/0xdarkmatter/doc-scanner in aiskillstore/marketplace) into .claude/skills/doc-scanner in your project. Claude Code loads it when a task matches its description.
Run `npx skills add aiskillstore/marketplace --skill doc-scanner -a codex`. Or copy the skill folder (skills/0xdarkmatter/doc-scanner in aiskillstore/marketplace) into .agents/skills/doc-scanner in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill doc-scanner -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/doc-scanner, .gemini/skills/doc-scanner, .github/skills/doc-scanner and .opencode/skills/doc-scanner in your project.
SKILL.md names no scripts, command-line tools or credentials: Doc Scanner is instructions for the agent only. Its frontmatter pre-approves these tools: Glob, Read, Write, Bash.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Doc Scanner is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 644 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.4k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Doc Scanner: Using Agent Skills (addyosmani/agent-skills, 102k stars), Claude Reflect (BayramAnnakov/claude-reflect, 1.7k stars), Neat-Freak Knowledge Closeout (KKKKhazix/khazix-skills, 21k stars) and Task Observer (rebelytics/one-skill-to-rule-them-all, 3.2k stars).
