convoy

convoy is a skill for Claude Code, Codex from gastownhall/gastown. It costs 114 tokens per session (5,031 once invoked), scanned A, original, MIT.

A guide to Gastown's convoy system, which tracks a batch of related work items across different code areas and starts the next ready item when earlier work finishes.

In plain words
What is it for?
It helps write, debug, extend, and test convoy tracking, staged launches, dependency handling, and event-driven work dispatch.
Why use it?
It explains the system's dependencies, stages, event handling, and safety checks so batch work is launched in the intended order.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go test ./internal/convoy/... ./internal/daemon/... ./internal/cmd/... -count=1.

Good fit It helps write, debug, extend, and test convoy tracking, staged launches, dependency handling, and event-driven work dispatch.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

convoy 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.

Gastown Convoy System

The convoy system tracks batches of work across rigs. A convoy is a bead that tracks other beads via dependencies. The daemon monitors close events and feeds the next ready issue when one completes.

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.

convoy is a skill published in the GitHub repository gastownhall/gastown (18,000 stars, last pushed today), licensed MIT. It adds 114 tokens to every session and 5,031 once invoked, about $0.0006 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.
