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.

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 | $0.00043 | $0.00483 |
| Opus 5 | $0.00022 | $0.00242 |
| Sonnet 5 | $0.00009 | $0.00097 |
| Haiku 4.5 | $0.00004 | $0.00048 |
Grade A, and why
gas-town-cursor 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 12d 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
Gas Town + Cursor Agent CLI
Use this skill when working in this repository with the cursor agent preset (CLI binary cursor-agent, sometimes symlinked as agent).
Concepts
| Name | Meaning |
|---|---|
Preset cursor |
Gas Town agent id (GT_AGENT=cursor). Config lives in internal/config/agents.go (AgentCursor). |
Binary cursor-agent |
The Cursor Agent CLI process name for pane/detection; install docs may also symlink agent → same binary. |
| Hooks | Cursor lifecycle hooks are configured at .cursor/hooks.json (see preset HooksSettingsFile). |
Essential commands
- Build / run
gtfrom repo root:make buildorgo run ./cmd/gt …. - Point a session at the Cursor preset: spawn or config so the runtime uses
--agent cursor(or setGT_AGENT=cursorwhere applicable). - After changing hooks or settings:
gt up --restore(or role-specific restart) so agents reload config.
Resume semantics
The Cursor preset uses --resume <chatId> style resume (ResumeStyle: flag). Session identity is not carried in a dedicated env var in the same way as Claude’s CLAUDE_SESSION_ID; follow the preset fields in internal/config/agents.go (ResumeFlag, ResumeStyle).

Boundary
Project README is user-facing product overview; .cursor/README.md is Cursor-specific onboarding for this repo. Prefer linking to those files instead of duplicating long install steps inside skills.
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.

gas-town-cursor is a skill published in the GitHub repository gastownhall/gastown (18,000 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 483 once invoked, about $0.0002 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.
