| name | zread |
| description | Produce and consume a wiki-style knowledge base for a code repository via the `zread` CLI and its on-disk output under `./.zread/wiki/`. Use this skill whenever the user wants to understand, onboard onto, explore, summarize, map, or get an overview of an unfamiliar codebase; asks for architecture docs, a project wiki, a repo walkthrough, module/package explanations, or "what does this repo do"; wants to generate, regenerate, resume, browse, or serve code documentation locally; or mentions zread / zread.ai directly. Also use it proactively before diving into a large unknown repo — if `./.zread/wiki/current` exists, read the generated pages instead of crawling source file-by-file; if it doesn't, consider offering to run `zread generate`. The trigger is the intent (understand a codebase through generated docs), not the literal word "zread". |
zread skill
zread is a CLI that generates wiki documentation from code in the current
workspace using an LLM. Output lives under ./.zread/wiki/ in the workspace;
public repos can also be viewed at https://zread.ai.
This skill is intended for agent use. Read generated files directly from disk,
and use --stdio as the default mode for any zread command instead of trying
to parse the human TUI.
On-disk layout (read these directly)
Always run zread from the workspace root. After a successful generation:
./.zread/wiki/current — text file containing the active version id
(e.g. 2026-03-12-010203).
./.zread/wiki/versions/<id>/wiki.json — TOC: {id, generated_at, language, pages: [{slug, title, file, section, group, level}]}.
./.zread/wiki/versions/<id>/<file> — page markdown referenced by pages[*].file.
./.zread/wiki/drafts/ — in-progress generation; presence means a previous
run did not finish. drafts/wiki.json exists once the catalog phase
completed.
~/.zread/config.yaml — global config (LLM provider, language, concurrency).
~/.zread/login.json — presence indicates the user has logged in.
To answer questions about a codebase that already has zread output, read these
files directly with the file tools — do not invoke zread browse.
Commands
| Command | Purpose | Key flags |
|---|
zread generate | Generate wiki for cwd | -y/--yes, --draft resume|clear|cancel, --skip-failed, --stdio |
zread browse | Serve docs at http://localhost:9681+ and open browser | --generate, --version <id>, --host, --port, --stdio |
zread login | OAuth into BigModel/Z.AI to obtain an API key | --custom, --model, --stdio |
zread config | Edit ~/.zread/config.yaml | --stdio |
zread update | Self-update CLI | --stdio |
zread version | Print version | --stdio |
--stdio is supported on every command and turns the process into a JSON-line
machine protocol on stdin/stdout. See
references/stdio-protocol.md for the wire
format (events, waiting_for, done, quit). Load it whenever zread is
invoked from another program/agent.
Decision tree for an AI agent
-
User wants to read existing wiki content?
- Check
./.zread/wiki/current. If present, read wiki.json and the page
markdown directly. No CLI invocation needed.
- For known public GitHub repos, prefer the
mcp__zread__* tools
(get_repo_structure, read_file, search_doc) over running the CLI.
-
User wants to (re)generate docs?
- Confirm with the user first —
generate is long-running, calls an LLM,
and writes files. Get explicit consent in unfamiliar directories.
- Verify
~/.zread/login.json exists or ~/.zread/config.yaml has an
llm.api_key. If neither, run zread login first.
- If
./.zread/wiki/drafts/ exists, decide:
- resume previous run →
zread generate --draft resume -y
- throw away and start fresh →
zread generate --draft clear -y
- Otherwise:
zread generate -y.
- To not block on a few failing pages: add
--skip-failed.
-
User wants to view docs in a browser?
zread browse (add --generate to bootstrap if no wiki exists yet).
-
User wants to script zread / consume output programmatically?
- Use
--stdio and follow stdio-protocol.md. Do not screen-scrape the TUI.
Non-interactive invocation rules
- Always pass
-y to generate when running unattended; otherwise it stops
at a catalog confirmation gate.
- Always set
--draft explicitly when a draft may exist, so the command does
not prompt.
- For any command run from another agent/script, use
--stdio so output is
parseable JSON instead of ANSI TUI frames.
zread writes logs to ~/.zread/log/zread.log — read this if a run fails
silently.
Safety / blast radius
generate consumes LLM tokens (real cost) and can run for many minutes on
large repos. Confirm before launching.
generate writes only under ./.zread/ and does not commit anything to
git. It is safe to delete ./.zread/wiki/drafts/ to recover from a stuck
state.
update replaces the zread binary in place and is hard to reverse — only
run it when the user explicitly asks.
login opens a browser for OAuth; do not run it in a non-interactive
context unless the user has asked for it.
