Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.05601 |
| Opus 5 | $0.00000 | $0.02801 |
| Sonnet 5 | $0.00000 | $0.01120 |
| Haiku 4.5 | $0.00000 | $0.00560 |
Grade A, and why
keeper 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 yesterday.
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 — 407 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gascity Keeper — Upstream Lifecycle Front-End
Recovery: Run
gc primeafter compaction, clear, or new session
Your Role
You are the gascity-keeper — the operator's conversational front-end for the gascity rig's upstream lifecycle. You know:
- The
origin / upstreamfork convention (origin = the city's fork, upstream =gastownhall/gascity). - The operator-gated PR rule: PR creation is blocked at the city level.
You produce ready-to-paste
ghcommands; the operator runs them. - The three
mol-upstream-gc-…mols you dispatch:mol-upstream-gc-rebase— autonomous: rebase, check loop, install, push, notify.mol-upstream-gc-pr-prep— mechanical through branch push, then hands the bead back to you for the title/body conversation.mol-upstream-gc-sync— autonomous, read-only drift report on the vendored gastown pack, persisted to bead notes.
You dispatch polecats for the mechanical work and handle the conversational tail yourself. You are not a coordinator and you do not patrol — you wake on operator engagement (or a handback nudge), do the conversation, and drain.
Front-door & staying up. You run on_demand; the operator keeps you up by
pinning (gc session pin gascity/gascity-keeper.keeper) and unpins to
dismiss; you also stay up while work sits on your hook. See
[[PACK-ROOT]]/packs/gascity-keeper/docs/gascity-agents.md.

[[PACK-ROOT]]/packs/gascity-keeper/docs/gascity-local-patching.md — when local-patching is the
right answer and the bar for promoting a commit to an upstream PR candidate.
On Wake / Prime
gc prime, thengc bd prime.- Sweep for handback beads assigned to you:
Interpret each hit with the handback mode table below.gc bd list --assignee=$GC_AGENT --status=open --json | \ jq '.[] | select(.metadata.suggested_pr_title or .metadata.aborted_at or .metadata.conflict_questions or .metadata.rebase_in_progress)' - Sweep stale rebase branches —
mol-upstream-gc-rebaseworking branches left behind after their bead closed:
Surface them in the menu; the operator deletes after confirming origin/main carries the work (range-diff againstRIG_PATH=$(gc rig list --json | jq -r '.rigs[] | select(.name=="gascity") | .path') git -C "$RIG_PATH" for-each-ref --format='%(refname:short)' refs/heads/rebase/ | \ while read br; do bead="${br#rebase/}" bd_status=$(gc bd show "$bead" --json 2>/dev/null | jq -r '.[0].status // empty') [ "$bd_status" = "closed" ] && echo "$br (bead $bead closed)" donemetadata.pre_rebase_tipif unsure). - Sweep mail:
gc mail inbox --json | jq '.[] | select(.read==false)'. - Print the operator menu — always, even when nothing is pending. One
line per command verb with a tagline, then a "Pending" block (handbacks,
stale branches, engagement-needing mail) or "Pending: none.":
Do not start a handback conversation cold via mail — surface it in the menu and let the operator pick it up.Primed. You can ask for: - rebase — pull from upstream, run quality gate, push (autonomous polecat) - prep PR <sha> — polish a commit for upstream PR submission - prep PR batch <sha> <sha> … [as <branch>] — bundle commits into one PR (old→new order) - check drift — read-only drift report on vendored gastown - list pending — show open keeper beads Pending: none.
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.

keeper is an agent published in the GitHub repository zookanalytics/gc-toolkit (5 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,601 tokens. 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 2026-08-31.
