start

start is a skill for Claude Code, Codex from nicelight/DevRails-26. It costs 20 tokens per session (644 once invoked), scanned A, original, MIT.

A project-starting command and setup guide for DevRails 26. It routes work through an external bootstrap process or an existing Memory Bank workflow after the project's runtime skills have been installed.

In plain words
What is it for?
It helps install or use the project's start command, route a clarified request, and follow the target repository's AGENTS.md instructions.
Why use it?
Starting a project with the wrong setup can create unsupported files, unclear tasks, or conflicts with the repository's role rules. This guidance defines what must be clarified before work begins.

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

start 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 1mo 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.

Start

What This Skill Is

start is the package-level entrypoint for starting DevRails in a target repository. It does not bootstrap the target itself.

Do not confuse two related surfaces:

  • Package/install surface: use the installer from an available external DevRails checkout to install runtime command skills or bootstrap the skeleton.
  • Generated project command: /start is the lightweight scenario router used after runtime skills are installed in the target repository.

The generated /start command is sourced from skills/_shared/references/commands/start.md in this source repo and is written into target .agents/skills/start/SKILL.md and .claude/skills/start/SKILL.md by scripts/install-framework.mjs.

Non-Negotiables

  • Do not create epics, features, implementation plans, or runnable task records without a clarified PRD/delta.
  • Do not create .memory-bank/commands/; runtime command skills are installed directly into .agents/skills/ and .claude/skills/.
  • Do not assume ORCHESTRATOR role or spawn subagents. Follow the target AGENTS.md role contract.
  • Do not use direct npx skills add <source-repo> for this source-only fork. Use scripts/install-framework.mjs from an available external DevRails checkout; it prepares a temporary vendored copy.
  • Keep skeleton/bootstrap separate from product planning. A fresh skeleton has empty .memory-bank/tasks/index.json and no FT-000 or product task records.

If .memory-bank/ Is Missing

Treat the current repository root as <target-repo> unless the operator explicitly supplied another target. Accept <devrails-checkout> only when the operator supplied it or its scripts/install-framework.mjs is already verifiable at a known path. Never guess or invent <devrails-checkout>.

Explain that this route installs or updates the full DevRails runtime command set and creates the skeleton. Then return this external bootstrap command with both placeholders replaced by verified, shell-safe paths:

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.
