Gas Town is a workspace manager for coordinating multiple AI coding agents across projects while preserving their work state in git-backed records. Developers use it to organize agents, tasks, identities, mailboxes, and handoffs across repositories. Its catalogue add-ons support operating and coordinating Gas Town workflows.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00114 | $0.05031 |
| Opus 5.5 | $0.00046 | $0.02012 |
| Sonnet 5.5 | $0.00023 | $0.01006 |
| Haiku 4.5 | $0.00011 | $0.00503 |
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 2mo 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 — 391 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.

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.

convoy is a skill published in the GitHub repository gastownhall/gastown (18,711 stars, last pushed 9d ago), licensed MIT. It adds 114 tokens to every session and 5,031 once invoked, about $0.0005 per session on Opus 5.5. 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.
