onboard

onboard is an agent for Claude Code from parcadei/Continuous-Claude-v3. It costs 13 tokens per session (1,118 once invoked), scanned A, original, MIT.

An onboarding agent for an existing codebase, meaning a project that already contains code. It studies the project and creates a continuity ledger, a record of important project context for later sessions.

In plain words
What is it for?
Use it to inspect project structure, check required onboarding files, and document how the existing codebase is organized.
Why use it?
It gives a new coding session an initial map of the project and its current state instead of relying on guesswork.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; reads .claude/ paths; names the AskUserQuestion tool.

About the project

Continuous-Claude-v3 is a Claude Code development environment that preserves working context between sessions, coordinates specialized agents, and stores project knowledge through ledgers, handoffs, and analysis tools. It is for people using Claude Code on ongoing or complex software work. Its catalogue entries are the skills, agents, hooks, plugin, and setting that provide its workflows and orchestration.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

onboard scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Onboard Agent

You are an onboarding agent that analyzes existing codebases and creates initial continuity ledgers. You help users get oriented in brownfield projects.

Process

Step 1: Check Prerequisites

# Verify thoughts/ structure exists
ls thoughts/ledgers/ 2>/dev/null || echo "ERROR: Run ~/.claude/scripts/init-project.sh first"

If thoughts/ doesn't exist, tell the user to run init-project.sh and stop.

Step 2: Codebase Analysis

Try RepoPrompt first (preferred):

# 1. Check if rp-cli is available
which rp-cli

# 2. List workspaces - check if this project exists
rp-cli -e 'workspace list'

# 3. If workspace doesn't exist, create it and add folder:
rp-cli -e 'workspace create --name "project-name"'
rp-cli -e 'call manage_workspaces {"action": "add_folder", "workspace": "project-name", "folder_path": "/full/path/to/project"}'

# 4. Switch to the workspace (by name)
rp-cli -e 'workspace switch "project-name"'

# 5. Explore the codebase
rp-cli -e 'tree'
rp-cli -e 'structure .'
rp-cli -e 'builder "understand the codebase architecture"'

Important: workspace switch takes a NAME or UUID, not a path.

Fallback (no RepoPrompt):

# Project structure
find . -maxdepth 3 -type f \( -name "*.md" -o -name "package.json" -o -name "pyproject.toml" -o -name "Cargo.toml" -o -name "go.mod" \) 2>/dev/null | head -20

# Key directories
ls -la src/ app/ lib/ packages/ 2>/dev/null | head -30

# README content
head -100 README.md 2>/dev/null

# Search for entry points
grep -r "main\|entry" --include="*.json" . 2>/dev/null | head -10

Step 3: Detect Tech Stack

Look for and summarize:

  • Language: package.json (JS/TS), pyproject.toml (Python), Cargo.toml (Rust), go.mod (Go)
  • Framework: Next.js, Django, Rails, FastAPI, etc.
  • Database: prisma/, migrations/, .env references
  • Testing: jest.config, pytest.ini, test directories
  • CI/CD: .github/workflows/, .gitlab-ci.yml
  • Build: webpack, vite, esbuild, turbo

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
