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 | $0.00048 | $0.00363 |
| Opus 5.5 | $0.00019 | $0.00145 |
| Sonnet 5.5 | $0.00010 | $0.00073 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
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.
What it actually says
Before this session ends, do ALL of the following. Do not skip any step.
-
Update
docs/ROADMAP.mdif a surface changed state: tick a row ✅ on merge, flip 🚧/🔒, add a row for a newly planned surface, and refresh the ADR/issue columns. This is the versioned "are we there yet?" source of truth — bookkeeping goes in its OWN commit, never bundled with feature code. (docs/CURRENT_STATUS.mdis no longer versioned — #79. If you keep a local one, it is yours; do not commit it.) -
If a convention was clarified or a pattern was corrected this session, update
docs/CONVENTIONS.mdaccordingly. Do NOT leave corrections only in chat history — they'll be lost next session. -
If a significant decision was made informally (in chat, in a review, in passing), propose creating an ADR via
/new-decisionbefore closing. -
Stage all
docs/changes in the SAME commit/PR as the session's code changes. Context updates ship with code, not after.
Do NOT close the session without completing step 1.
After completion, output a one-paragraph session summary suitable for pasting into the PR description.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

session-close is a skill published in the GitHub repository albertomarturelo/sii (16 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 363 once invoked, about $0.0002 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 2026-10-24.

work
Handle issue/PR work items with worktree isolation. Triggered by "/work [issuelink|description]" to start focused work.
close-task-commit-push-pr
Close the active backlog task (detected from branch name), commit all changes, push to remote, and open a pull request. Use when the user says "close task and ship it", "close task commit push pr", or invokes /close-task-commit-push-pr.
setup-caliber
Sets up Caliber for automatic AI agent context sync. Installs pre-commit hooks so CLAUDE.md, Cursor rules, and Copilot instructions update automatically on every commit. Use when Caliber hooks are not yet installed or when the user asks about keeping agent configs in sync.
do
Work a SpecWeave increment task by task - claim, implement inside its Files, test, commit, done with evidence - alone, unattended or in lanes, then close. Use for "implement", "continue", "auto".
