go-start

go-start is a skill for Claude Code, Codex from bearded-illirian/trailmark. It costs 66 tokens per session (1,716 once invoked), scanned A, original, MIT.

A session-start workflow that loads shared platform guidance and the selected project’s documentation. It also distinguishes a new task from a continuation of an interrupted one.

In plain words
What is it for?
Use it at the start of a terminal session to load project context, choose a project, and resume interrupted work.
Why use it?
It reduces the setup work needed before coding and restores context when a previous session was stuck or interrupted.

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

go-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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Go-Start — Session Start

Loads platform and project context in a single run. One command, agent is ready.

Three phases:

  1. Platform — read common platform docs
  2. Project — read docs of the selected project
  3. Session type — new task or resuming a stuck session

Input

The session-start signal (user invoking /go-start in a fresh terminal).

Output

Loaded platform + project context in-session; numbered project menu shown; session type resolved to new or continuation.

Hands off to

go-fast (new session), or resumes the interrupted task's per-block cycle (continuation).


Phase 1 — Platform

Step 1.1 — Read platform files

Read all five sequentially:

  • {tasks_root}/README.md
  • {tasks_root}/docs/core/WORKFLOW.md
  • {tasks_root}/docs/core/DEPLOY.md
  • {tasks_root}/docs/core/PLATFORM_KNOWLEDGE.md
  • {tasks_root}/projects.yml

Rule: read all five — do not skip even if you think you already know the content. Each session starts from a clean slate.

Step 1.1.5 — Cleanup stale git locks

Before the summary — silently run a helper that scans active projects and clears stale .git/index.lock files (>5 min old). Idempotent. Capture stdout for use in the summary line.

Why: background git commands can hang for hours, hold .git/index.lock and block the repo. The helper kills the offending process and removes the file.

Step 1.2 — Output platform summary

A compact block (no more than 8 lines):

✅ Platform loaded.

Servers: {msk_vds} | {nl_vds}
Deploy: git push origin main → post-receive → auto-backup
Skills: {skills_project}/.agents/skills/ → sync-agents.sh → all projects
Artifacts: task_artifacts in routing.db
Git locks: {helper result}

Do not retell files in full — only operationally important information.

Step 1.3 — Project menu

Take only status: active from projects.yml. Output a numbered list with id / name / domain. Wait for explicit user selection — do not guess, do not proceed to Phase 2 without it.

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.
