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

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

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

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

This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.

How to use it

Copy the folder

Take wednesday-solutions/onboard-dev-agent from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
