What it does

CLI Hub Matrix Knowledge Research is an agent skill from HKUDS/CLI-Anything. Capability-based multi-tool matrix for research, note-taking, document authoring, and publishing. Agents compose providers (CLI-Anything harnesses, public CLIs, Python libs, native binaries, cloud APIs) per capability.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management, covering Note-taking and Diagrams. It works with Python and Notion. The repository describes itself as: "CLI-Anything: Making ALL Software Agent-Native" -- CLI-Hub: https://clianything.cc/. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Note-taking
  • Tasks that involve Diagrams

Example prompts

  • “/cli-hub-matrix-knowledge-research”

Requirements

  • Python 3
  • A credential in OPENAI_API_KEY
  • A credential in ANTHROPIC_API_KEY

Workflow steps

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

  1. Use preflight as an availability report, not as a provider selector.
  2. Treat provider order as documentation order only.
  3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
  4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

What it can do on your machine

Read from SKILL.md and the folder at commit 34f5195. 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

    Shell commands in SKILL.md call:

    • python

    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 these keys or tokens, usually read from environment variables:

    • NOTION_API_KEY
    • PERPLEXITY_API_KEY
    • TAVILY_API_KEY
    • BRAVE_API_KEY
    • GOOGLE_API_KEY
    • FIRECRAWL_API_KEY
    • SEMANTIC_SCHOLAR_API_KEY
    • GHOST_ADMIN_KEY
    • EXA_API_KEY
    • SCRAPINGBEE_API_KEY
    • CLOUDCONVERT_API_KEY
    • OVERLEAF_API_KEY

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

Context cost

CLI Hub Matrix Knowledge Research loads about 2.8k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 985 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

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); files beside SKILL.md are not scanned.

description
Capability-based multi-tool matrix for research, note-taking, document authoring, and publishing. Agents compose providers (CLI-Anything harnesses, public CLIs, Python libs, native binaries, cloud APIs) per capability.

Knowledge / Office / Research Matrix (S2 — v2 capability-based)

Scenario S2. Strongest coverage in the current ecosystem: search, reference management, notes, synthesis, documents, and diagrams all have first-party harnesses; Python/native fallbacks fill the rest.

Schema: docs/cli-matrix/matrix_registry.schema.md. Matrix plan: docs/cli-matrix/cli-matrix-plan.md.

Install

bash
cli-hub matrix install knowledge-research
cli-hub matrix info    knowledge-research
cli-hub matrix preflight knowledge-research --json

Provider selection constraints

  1. Use preflight as an availability report, not as a provider selector.
  2. Treat provider order as documentation order only.
  3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
  4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

Offline context? Filter to offline: true providers.

Preflight

Run cli-hub matrix preflight knowledge-research --json first. Use the manual block below for extra probes or older cli-hub versions.

bash
cli-hub list --json
python - <<'PY'
import importlib.util
for m in ("pyzotero","bibtexparser","trafilatura","readability","httpx","playwright",
          "python_docx","openpyxl","pptx","reportlab","pypdf","pdfplumber","weasyprint",
          "langchain","llama_index","haystack"):
    print(m, importlib.util.find_spec(m) is not None)
PY
for b in pandoc qpdf pdftk exiftool latexmk tex dot mermaid plantuml hugo mkdocs jekyll; do
  command -v "$b" >/dev/null && echo "$b: yes" || echo "$b: no"
done
for e in OPENAI_API_KEY ANTHROPIC_API_KEY GOOGLE_API_KEY PERPLEXITY_API_KEY TAVILY_API_KEY \
         SERPAPI_API_KEY BRAVE_API_KEY FIRECRAWL_API_KEY \
         NOTION_API_KEY SEMANTIC_SCHOLAR_API_KEY WORDPRESS_TOKEN GHOST_ADMIN_KEY; do
  [ -n "${!e}" ] && echo "$e: set" || echo "$e: unset"
done

Suggest-to-user template

To enable <capability> via <provider>, please set <ENV_VAR>.
  Cost: <cost notes>
  Quality: <quality tier>
Reply 'skip' to fall back to <next provider>.

Example: To enable live Notion sync via the Notion API, please set NOTION_API_KEY. Cost: free tier suffices for most users. Quality: sota (round-trips block/page IDs). Reply 'skip' to fall back to local Obsidian vault + manual paste.

Recipes

  • literature-review — survey a topic, extract key papers, synthesize. Uses: research.search, research.retrieve, research.reference, knowledge.synthesize, document.author.

  • meeting-to-doc — turn a recorded meeting into a structured document. Uses: text.transcribe (via S1 matrix), knowledge.synthesize, document.author, document.format.

  • blog-post — research → write → publish. Uses: research.search, research.retrieve, knowledge.synthesize, document.author, publish.web.

  • paper-draft — research + citations + LaTeX. Uses: research.reference, knowledge.synthesize, document.author, publish.latex.

  • competitive-brief — fetch competitor pages, extract positioning, produce a briefing deck. Uses: research.retrieve, knowledge.synthesize, document.author (PPTX).

  • pdf-book-digest — ingest a PDF book, OCR if needed, produce chapter summaries + quote file. Uses: document.pdf, knowledge.synthesize, knowledge.note.

Known gaps

  • Notion — Notion API exists as an escalation, but there is no harness for local-first Notion workflows. Recurs in S11 (team comms).
  • Google Docs / Microsoft 365 live editing — API path only.
  • LaTeX harness — latexmk + Tectonic cover the native path, but no agent-native wrapper yet.
  • Translation — no first-party CLI; Python fallback and APIs only.

Agent guidance

  • Run preflight once per session. Many capabilities have strong Python or native paths that bypass the need to install anything.
  • Prefer local for sensitive docs (legal, health, internal): use Obsidian + local LLM + whisper rather than cloud APIs.
  • Citations are load-bearing — for academic work always route through research.reference so bibliographies stay consistent.
  • Chain document.format at the end, not the middle: author in the richest source format (markdown or LaTeX) and convert last.
  • Workspace discipline — one directory per project; keep refs.bib, source markdown, figures, and output PDFs colocated.
