What it does

Codexqa Code Wiki is an agent skill from openqa-cn/codexqa. Builds a local architecture wiki for a repository from the CodexQA symbol graph (no model needed): modules, who calls whom and how often, reading paths, and one self-contained HTML page. Use when the user mentions codexqa-code-wiki, code-wiki, wiki, knowledge graph, architecture wiki, module map, reading guide, 代码知识图谱, 架构 Wiki, 模块地图, 阅读导览, wiki inputs, --no-llm, community detection, 社区检测, HTML 报告, or asks to map modules / generate a repo wiki without an LLM. Not change review (that is codexqa-code-analyzer), not…

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 33 other files, including scripts, reference files and assets (for example `KNOWN_LIMITATIONS.md`, `KNOWN_LIMITATIONS.zh-CN.md` and `README.md`). Compatibility notes: Requires Node.js = 18 and the codexqa CLI (npm i -g @openqa-cn/codexqa) on PATH. Index and wiki inputs need no LLM. Data lives in ~/.codexqa/.

It sits in Knowledge Management, covering Static analysis and SAST, Code review and HTML artifacts. The repository describes itself as: codexqa: 11 local-first Agent Skills for Cursor, Claude Code, Codex & OpenClaw — change impact analysis, AI code review, defect scan, testcase generation, browser replay & RCA. The licence is Apache-2.0.

When your agent uses it

  • The user mentions codexqa-code-wiki
  • Knowledge graph
  • Architecture wiki
  • Community detection

Example prompts

  • “Use the codexqa-code-wiki skill to build a local architecture wiki for a repository from the CodexQA symbol graph (no model needed): modules, who…”
  • “/codexqa-code-wiki”

Requirements

  • Node.js
  • Compatibility (from SKILL.md): Requires Node.js >= 18 and the `codexqa` CLI (`npm i -g @openqa-cn/codexqa`) on PATH. Index and `wiki inputs` need no LLM. Data lives in ~/.codexqa/.

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Brief. Run node /scripts/wiki.mjs brief . It indexes
  2. Notes. Read references/notes.md, then fill
  3. Build. Run node /scripts/wiki.mjs build . If it prints
  4. Deliver. Tell the user the printed file path plus two or three lines on

What it can do on your machine

Read from SKILL.md and the folder at commit 7839542. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 6 files in scripts/ (JavaScript, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires Node.js >= 18 and the `codexqa` CLI (`npm i -g @openqa-cn/codexqa`) on PATH. Index and `wiki inputs` need no LLM. Data lives in ~/.codexqa/.

    From compatibility in the SKILL.md frontmatter.

Context cost

Codexqa Code Wiki loads about 1.3k tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 177 tokens; SKILL.md has 526 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~177
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.1k

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated 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.

Code Wiki

Three commands, one file to write:

text
node <skill>/scripts/wiki.mjs brief <repo>   # index + export facts + print the brief
  → you write .codexqa-wiki/<repo>/notes.json  # names and sentences only
node <skill>/scripts/wiki.mjs build <repo>   # validate + render one HTML file

The script owns every fact on the page: modules, sizes, call counts, groups, the architecture diagram, public symbols, files, links, search. You own the words: what the repo is, what each module does, and which reading path fits which task. You never edit HTML, CSS, or diagrams.

<skill> is this skill's directory. <repo> is a local checkout (preferred). README.md / README.zh-CN.md are for humans; do not load them.

Documents (load on demand)

FileLoad when
SKILL.md (this file)always
references/notes.mdbefore writing notes.json
references/playbook.mdone module only, index problems, persisting for the Web UI
references/cli.mdcodexqa missing, PATH, repo ids, maintenance

Default flow

  1. Brief. Run node <skill>/scripts/wiki.mjs brief <repo>. It indexes incrementally, exports codexqa wiki inputs, and writes .codexqa-wiki/<repo>/ with inputs.json, meta.json, brief.md, and a notes.json scaffold (kept if it already exists). Read the printed brief: groups, suggested paths, and per module its files, calls, callers, public symbols, and key flows.
  2. Notes. Read references/notes.md, then fill notes.json. Every P01-style id and group id in it must exist in the brief. Write 简体中文 unless the user asked for English ("lang": "en").
  3. Build. Run node <skill>/scripts/wiki.mjs build <repo>. If it prints error: lines, fix those fields and rerun; they name the field and the fix. check <repo> validates without writing HTML.
  4. Deliver. Tell the user the printed file path plus two or three lines on what the wiki says. Do not paste the HTML or open it in chat.

The user only wants a quick look → build <repo> --draft right after brief. The page uses rule-based names and says it is a draft. Offer to write the notes afterwards.

Useful flags: brief --limit 8 (large repos), brief --lang en, brief --skip-index (index is fresh), build --out FILE, build --source-url 'https://host/repo/blob/{commit}/{path}' (file links when the remote is not GitHub / GitLab / Gitee / Bitbucket).

Scenario routing

User is asking…Do
What is this repo / module map / architecture wiki / knowledge graphDefault flow
Where should I start reading / onboarding pathDefault flow; put the effort into guides
What does module X do / who does it talk toAnswer from brief.md; deeper digest in playbook Explain one module
Store a rule-only wiki for the CodexQA Web UIplaybook Persist rule-only wiki
brief failed / empty export / wrong branchplaybook Index health

Change review, callers of a symbol, test gaps, and stack traces belong to codexqa-code-analyzer.

Rules

  • Facts come only from this run's export. Do not add modules, calls, or responsibilities that the brief does not support; do not use the README or a website as evidence for a module's role.
  • A reading path follows real calls: each step must call or be called by the next. build rejects anything else and lists the valid neighbours.
  • Standalone modules (no calls to or from other modules) get a name and a role, never a layer.
  • Write for someone who just cloned the repo. No internal field names (deps, cross_community, called_by, wiki inputs); build rejects them.
  • Do not run codexqa wiki without --no-llm, wiki embed, or query wiki. Those call a model or need model-written pages.
  • Do not hand-edit the generated HTML. Change notes.json and rebuild.
