What it does
Onboard is an agent skill from atherio-danp/cde-dotnetcc. Produce a structured "get up to speed on this whole project" orientation — vision, architecture, where things live, conventions, how to do common tasks, current state — grounded in the real code/config with pointers. Optionally writes/updates docs/ONBOARDING.md. Use when asked to onboard, give a project overview, or "how does this project work / where do I start". Read-only except the optional doc write.
Its SKILL.md is about 990 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 Agent Workflows. The repository describes itself as: Claude Code harness for .NET developers.
When your agent uses it
- Asked to onboard
- Give a project overview
- How does this project work / where do I start
Example prompts
- “get up to speed on this whole project”
- “how does this project work / where do I start”
- “/onboard”
Requirements
- Docker
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash, Edit, Write, Skill, mcp__serena__initial_instructions, mcp__serena__get_symbols_overview, mcp__serena__find_symbol, mcp__serena__find_referencing_symbols, mcp__serena__find_declaration, mcp__serena__find_implementations, mcp__serena__search_for_pattern, mcp__serena__get_diagnostics_for_file, mcp__serena__list_dir, mcp__serena__find_file
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Reconnaissance via Glob/Grep — NOT Read-everything. Detect manifests (*.csproj, package.json, …),
- Vision first. Lead with the product context (docs/product-overview.md + the injected product-context)
- Architecture map. Stack, layout (monorepo apps/web + apps/api), layers + dependency direction, API
- Conventions from the code itself — naming, error handling (Result / ProblemDetails), async discipline,
- Rank, don't dump. Surface the most-referenced / central files and the authoritative rules/skills — not an
- Common tasks — verified, not assumed. The real build/test/run commands (from docs/config), and the operating
- "Where to look" map. Table: goal → location (incl. the rules/skills/agents that govern that area).
- Flag unknowns / drift explicitly — never guess; if doc↔code drift is obvious, note it (and suggest /docs-standards-sync).
- Optional artifact (--write): write/refresh docs/ONBOARDING.md. If it (or CLAUDE.md) already exists,
What it can do on your machine
Read from SKILL.md and the folder at commit c72a3f9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepBashEditWriteSkillmcp__serena__initial_instructionsmcp__serena__get_symbols_overviewmcp__serena__find_symbol
…and 7 more on the same allowed-tools line.
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
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
Onboard loads about 992 tokens when it runs. Until then it costs about 104 tokens; SKILL.md has 370 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Glob, Grep, Bash, Edit, Write, Skill, mcp__serena__initial_instructions, mcp__serena__get_symb
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 370 words (~992 tokens).
“Produce a coherent orientation to the WHOLE project, grounded in the real files. Obey the source-of-truth authority hierarchy in CLAUDE.md (code → SQL → telemetry → docs → AI output) — verify against the code, treat docs as leads. Documentarian…”

Onboard is an agent skill from atherio-danp/cde-dotnetcc. Produce a structured "get up to speed on this whole project" orientation — vision, architecture, where things live, conventions, how to do common tasks, current state — grounded in the real code/config with pointers.
When should I use Onboard?
Onboard fits situations like: asked to onboard; give a project overview; how does this project work / where do I start.
How do I install Onboard in Claude Code?
Run `npx skills add atherio-danp/cde-dotnetcc --skill onboard -a claude-code`. Or copy the skill folder (.claude/skills/onboard in atherio-danp/cde-dotnetcc) into .claude/skills/onboard in your project. Claude Code loads it when a task matches its description.
How do I install Onboard in Codex?
Run `npx skills add atherio-danp/cde-dotnetcc --skill onboard -a codex`. Or copy the skill folder (.claude/skills/onboard in atherio-danp/cde-dotnetcc) into .agents/skills/onboard in your project. Codex loads it when a task matches its description.
Can I use Onboard 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 atherio-danp/cde-dotnetcc --skill onboard -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/onboard, .gemini/skills/onboard, .github/skills/onboard and .opencode/skills/onboard in your project.
What does Onboard need to run?
SKILL.md names no scripts, command-line tools or credentials: Onboard is instructions for the agent only. Our summary lists: Docker. Its frontmatter pre-approves these tools: Read, Glob, Grep, Bash, Edit, Write, Skill, mcp__serena__initial_instructions, mcp__serena__get_symbols_overview, mcp__serena__find_symbol, mcp__serena__find_referencing_symbols, mcp__serena__find_declaration, mcp__serena__find_implementations, mcp__serena__search_for_pattern, mcp__serena__get_diagnostics_for_file, mcp__serena__list_dir, mcp__serena__find_file.
Does Onboard 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 Onboard safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Onboard use?
No licence was found for Onboard or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Onboard use?
About 992 tokens (SKILL.md is roughly 4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Onboard?
Skills that share tags, products or a category with Onboard: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 297k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
