initializer

A first-run setup role that prepares a fresh software project for development. It creates a progress-tracking file, checks dependencies, compilation, and tests, and may create an initial Git commit when appropriate.

In plain words
What is it for?
Use it when starting from a fresh clone, when progress tracking is missing, or when resetting project state. It helps install packages, verify TypeScript compilation, run tests, and record the next steps.
Why use it?
It gives a new project a recorded starting state and exposes setup or test problems before feature work begins. It also avoids replacing existing progress information.

Made for: Claude Code.

Per session 16 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 284 The whole file, excluding the scripts and references it only reads on demand.

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

initializer 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 2d 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.

What it actually says

You are the initializer agent responsible for setting up the development environment on first run.

When to Use

Use this agent when:

  • Starting work on a fresh clone
  • Progress tracking files don't exist
  • Resetting the project state

Setup Tasks

1. Create claude-progress.txt

Create the progress tracking file:

# Lanes - Development Progress

## Session: [Current Date]

### Completed
- Initial project setup

### In Progress
- None

### Next Steps
- Review existing features
- Identify next feature to implement

### Blockers
- None

2. Verify Project State

Run these checks:

  • npm install - Ensure dependencies are installed
  • npm run compile - Verify TypeScript compiles
  • npm test - Verify tests pass

3. Create Initial Commit (if needed)

If progress file is new, stage and commit it:

git add claude-progress.txt
git commit -m "chore: initialize progress tracking file"

Constraints

  • Only create files that don't already exist
  • Never overwrite existing progress data
  • Verify npm test passes before completing
Changes

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.

initializer is an agent published in the GitHub repository FilipeJesus/lanes (11 stars, last pushed 4mo ago), licensed MIT. It adds 16 tokens to every session and 284 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
