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 | $0.00115 | $0.01290 |
| Opus 5.5 | $0.00046 | $0.00516 |
| Sonnet 5.5 | $0.00023 | $0.00258 |
| Haiku 4.5 | $0.00012 | $0.00129 |
Grade A, and why
gopherstack-session-close 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
gopherstack session close
Work is not complete until git push succeeds and git status shows up
to date with origin. Committed-but-unpushed work is stranded and the exact
failure this protocol exists to prevent. Never end a session on "ready to
push when you are" — push it yourself.
Pre-flight checklist
- Anything left to do? File a
bdissue for it — don't leave it in your head or a comment. - Did code change? Run the gate subset for what changed (see
gopherstack-gatesskill for the decision table; short version below). - Any
bdissues you worked finished, or in progress? Update their status. - Run the push sequence below, in order, without skipping steps.
- Confirm
git statusliterally says up to date with origin before reporting done.
Ordered close sequence
# 1. File issues for anything unfinished (repeat per item)
bd create --title="<title>" --description="<desc>" --type=task --priority=<0-4>
# 2. Gates, only if code changed — see gate-subset table below
# 3. Update tracker state
bd update <id> --claim # if you're taking something on
bd close <id> [--reason="<why>"]
# 4. Audit trailers on the branch, before the PR is squashed; reconcile any
# TRAILER MISMATCH / TYPO'D TRAILER ID findings
task bd-audit
# 5. MANDATORY push sequence — do not stop partway
# Do NOT run `bd dolt push`: embedded Dolt, no remote, silently does nothing
git pull --rebase
git add .beads/issues.jsonl # bd's auto-export hook usually does this
git push
git status # MUST show "up to date with origin"
If git push fails, resolve and retry until it succeeds. Do not leave the
session with unpushed commits, even if the failure looks like someone
else's problem (rebase conflict, stale branch, etc.) — resolve it.
Gate subset by what changed
| what changed | run before closing |
|---|---|
| Nothing (pure investigation/planning) | none — but still push any bd issue changes |
| One service's Go code | go test -race ./services/<svc>/... |
Shared pkgs/ code |
go build ./... plus tests for every consumer you touched |
| Anything you intend to open a PR from | full gate: task lint && task test && task build-linux && task integration-test |
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.

gopherstack-session-close is a skill published in the GitHub repository BlackbirdWorks/gopherstack (17 stars, last pushed yesterday), licensed MIT. It adds 115 tokens to every session and 1,290 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 2026-11-07.
