At a glance

Turn any codebase into an explorable interactive graph so a developer can understand it fast.

  • Works in 3 steps: Scan (always start here) → Enrich (this is your real work) → Render and verify
  • Asked to explain
  • SKILL.md covers When to Use, Core Design (read this before…, Instructions and What the artifact gives the…, plus 4 more sections
  • Runs Python scripts from its folder; calls python3

What it does

Codegraph is an agent skill from SylphAI-Inc/skills. Turn any codebase into an explorable interactive graph so a developer can understand it fast. Deterministic scan (files, imports, symbols, call edges, PageRank importance, architectural layers, dependency cycles, entry points) plus optional AI enrichment (plain-English summaries and guided tours), delivered as ONE self-contained HTML file. Use when asked to explain, map, visualize, diagram, onboard onto, or understand a repository or its architecture.

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts and assets (for example `README.md`, `README.zh-CN.md` and `scripts/overview.py`).

It sits in Writing & Content, covering Plain language and style rules. The repository describes itself as: Community-shareable skills for AdaL — the automation-first agent harness.

When your agent uses it

  • Asked to explain
  • Understand a repository
  • Its architecture

Example prompts

  • “/codegraph”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Scan (always start here)
  2. Enrich (this is your real work)
  3. Render and verify

What it can do on your machine

Read from SKILL.md and the folder at commit 51a5abd. 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 5 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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.

Context cost

Codegraph loads about 3.5k tokens when it runs. Until then it costs about 116 tokens; SKILL.md has 1,753 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~116
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,753 words (~3,491 tokens).

“Turn a codebase into a map a human can actually read.”

Can I use Codegraph in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add SylphAI-Inc/skills --skill codegraph -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/codegraph, .gemini/skills/codegraph, .github/skills/codegraph and .opencode/skills/codegraph in your project.

What does Codegraph need to run?

Going by SKILL.md and its folder, Codegraph needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.

Does Codegraph access the network?

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.

Is Codegraph safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. 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.

What licence does Codegraph use?

No licence was found for Codegraph or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Codegraph use?

About 3.5k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
