lanes: Skill for Claude Code

.agents/skills/initializer/SKILL.md

initializer is a skill for Claude Code, Codex from FilipeJesus/lanes. It costs 29 tokens per session (352 once invoked), scanned A, original, MIT.

A first-run setup procedure for a fresh Lanes checkout. It installs dependencies, checks compilation and tests, and creates progress tracking without overwriting existing progress.

In plain words
What is it for?
Use it when beginning work in a fresh clone, when setup tracking is missing, or when resetting development setup.
Why use it?
It provides a repeatable starting point and catches setup problems before development begins.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is FilipeJesus/lanes's own configuration. It tells Claude Code and Codex how to work on lanes itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything lanes configures →

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 11d 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

Initialize Development Setup

Set up the development environment on first run.

When to Use

Use this skill when:

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

Setup Tasks

1. Create agent-progress.txt

Keep an existing agent-progress.txt. If only claude-progress.txt exists, rename it to agent-progress.txt and preserve its contents. If neither exists, 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 ci - Install dependencies from the lockfile
  • npm run compile - Verify TypeScript compiles
  • npm test - Verify tests pass

3. Create Initial Commit (if needed)

If the task includes creating a commit and the progress file is new, stage and commit it:

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

Constraints

  • Only create files that don't already exist
  • Never overwrite existing progress data
  • If claude-progress.txt exists, preserve its contents when migrating it to agent-progress.txt; do not replace it with the initial template
  • 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.
