At a glance

A skill your agent uses when the user says 'cognee', asks about knowledge graph or graph memory, wants to switch memory backends, or needs a status check, dataset init, or graph view.

  • Works in 5 steps: Ask the user for the dataset name… → Check if a dataset with that name… → If it exists: "Dataset 'X' already… → …
  • The user says cognee
  • SKILL.md covers Quick Reference, Sub-commands, Architecture and Behavior Rules, plus 1 more section
  • Calls curl, jq and pip

What it does

Cognee is an agent skill from coco-research/coco. Use when the user says 'cognee', asks about knowledge graph or graph memory, wants to switch memory backends, or needs a status check, dataset init, or graph view. Covers Cognee endpoints plus the Brain fallback.

Its SKILL.md is about 1.3k 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 Knowledge graphs. The repository describes itself as: CoCo Super Intelligence is the orchestration layer that turns Claude Code, Cursor, or Codex into an engineering department: a routed advisory board, 226 skills, 386 commands…

When your agent uses it

  • The user says cognee
  • Asks about knowledge graph
  • Wants to switch memory backends
  • Needs a status check

Example prompts

  • “cognee”
  • “/cognee”

Requirements

  • Python 3

Workflow steps

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

  1. Ask the user for the dataset name (default: current directory name, slugified).
  2. Check if a dataset with that name already exists
  3. If it exists: "Dataset 'X' already exists. Using it." → skip creation.
  4. If not: create it
  5. Confirm

What it can do on your machine

Read from SKILL.md and the folder at commit 2ddb559. 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:

    • curl
    • jq
    • pip

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

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    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.

Context cost

Cognee loads about 1.3k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 364 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 364 words (~1,322 tokens).

“A persistent knowledge graph memory system powered by Cognee. Stores entities, decisions, events, and relationships as graph nodes with embeddings, enabling semantic search across projects and sessions.”
