What it does
Codebase Onboarding is an agent skill from sickn33/agentic-awesome-skills. Onboard a developer to a repository using Ontoly graph summaries. Use when asked to explain a new codebase, identify entrypoints, map packages, or suggest first files to inspect.
Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files (for example `README.md`, `examples.md` and `reference/best-practices.md`). Compatibility notes: Portable Agent Skills format; requires Ontoly CLI and MCP-capable or CLI-capable coding agent.
It sits in Development, covering Codebase onboarding. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is AGPL-3.0-only.
When your agent uses it
- Asked to explain a new codebase
- Identify entrypoints
- Suggest first files to inspect
Example prompts
- “/codebase-onboarding”
Requirements
- Compatibility (from SKILL.md): Portable Agent Skills format; requires Ontoly CLI and MCP-capable or CLI-capable coding agent.
What it can do on your machine
Read from SKILL.md and the folder at commit 1e53ce2. 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
No scripts in the folder and no shell commands in SKILL.md.
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):
ontoly.xyzskills.sh
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
Portable Agent Skills format; requires Ontoly CLI and MCP-capable or CLI-capable coding agent.
From compatibility in the SKILL.md frontmatter.
Context cost
Codebase Onboarding loads about 610 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 183 words of instructions outside code blocks.
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.

When to Use
- Use when this upstream workflow matches the user's stated goal.
- Use when the task requires the procedures documented in this skill.
Codebase Onboarding
Use this skill when the user asks for codebase onboarding using Ontoly evidence.
Required Workflow
Follow [the shared Ontoly workflow. Also read [graph evidence rules, [MCP usage, [best practices, and [fallback rules when the task requires detail.
Ontoly Capabilities
Use these capabilities first: ExplainArchitecture, FindEntrypoints, GraphStatistics, FindFeatureOwner, EvidencePack.
Output Contract
Return:
- answer or plan
- capabilities invoked
- graph evidence with node ids, edge types, source spans, and graph hash when available
- confidence: high, medium, or low
- fallback reason if repository files were inspected
Boundaries
Do not implement compiler, query, MCP, SDK, or business logic in the skill. Do not search repository files until Ontoly cannot answer or evidence must be confirmed.
