What it does

Onboard Dev Agent is an agent skill from wednesday-solutions/ai-agent-skills. Use when a dev is new to the project, asks for an overview, or wants to get oriented quickly. Fills graph gaps then runs a guided codebase interview.

Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `agent.yml`).

The repository describes itself as: Pre-configured agent skills for Vibe Coded projects. These skills provide AI coding assistants (Claude Code, Cursor, etc.) with specific guidelines for code quality and design… The licence is MIT.

When your agent uses it

  • A dev is new to the project
  • Asks for an overview
  • Wants to get oriented quickly

Example prompts

  • “/onboard-dev-agent”

Workflow steps

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

  1. brownfield-fix — Before answering anything, check for high-risk files with low graph coverage
  2. brownfield-chat — Run a structured onboarding interview using the graph
  3. Finish with: "Which area would you like to explore first?"

What it can do on your machine

Read from SKILL.md and the folder at commit 80fa195. 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

    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 Dev Agent loads about 445 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 187 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~445

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.

Dev Onboarding Agent

When to use

  • "I'm new to this project, where do I start?"
  • "Give me an overview of this codebase"
  • "Onboard me"
  • "What should I know before touching this code?"

What to do

  1. brownfield-fix — Before answering anything, check for high-risk files with low graph coverage:

    • Run wednesday-skills fill-gaps --min-risk 60
    • This ensures the graph is reliable for the onboarding session
    • Report any gaps that were filled
  2. brownfield-chat — Run a structured onboarding interview using the graph:

    Answer each of these in order, citing sources:

    • "What does this project do?" — reads MASTER.md overview
    • "What are the main modules and what does each do?" — summaries.json
    • "What are the highest-risk files and why?" — dep-graph.json safety-scores
    • "What changed in the last 30 days?" — git log
    • "What are the architecture rules I must not break?" — PLAN.md boundaries or MASTER.md danger zones
    • "Which areas have low test coverage?" — dep-graph.json coverage data
  3. Finish with: "Which area would you like to explore first?"

Never

  • Answer from memory about a specific codebase — always read the graph
  • Skip the gap-filling step — it ensures reliable answers
  • Load the full dep-graph.json — query only relevant nodes
