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 | $0.00052 | $0.03813 |
| Opus 5 | $0.00026 | $0.01906 |
| Sonnet 5 | $0.00010 | $0.00763 |
| Haiku 4.5 | $0.00005 | $0.00381 |
Grade A, and why
end 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 — 211 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session End
End a work session cleanly. /lets:end is a settlement pass: it reconciles the volatile session state (uncommitted changes, unpushed commits, in-conversation context) into durable stores (git remote, the tracker, a session-snapshot file) so the window can close - or compact - without losing anything.
This is NOT task completion. Use /lets:done to finish a TASK; /lets:end ends a SESSION.
Invariant: /lets:end only READS the .task-<slug> session: boundary - it NEVER writes it. The boundary writers are take-task (at /lets:start) and the SessionStart hook (refresh on a genuinely new session). End mutating the boundary was the old --fast divergence bug; it stays gone.
IMPORTANT: If the spec below invokes any deferred tool (e.g.
AskUserQuestion), you MUST load and call it as specified. Never skip the call, never substitute a default answer of your own - the tool invocation is part of the contract. This is critical.
Modes
One settlement core (the default flow); the two flags below are separate paths, NOT modifiers of it:
- (default) - full settlement pass (Steps 1-3) + worktree hint + a one-line terminal prose hint (Step 4 / Output). Auto-skip keeps it silent on a tidy session.
--pre-compact(alias--compact) - a pre-compaction snapshot, NOT a session end and NOT a settlement pass. It runs NO settlement (no commit / push / progress / finish offers) - it ONLY writes the shared session snapshot viasession-snapshot(kind=precompact) and lets the session continue into/compact. Identical to/lets:note --pre-compact- both delegate to the same primitive with the skill owning task detection. See the early-exit at the top of Step 1.--fast- DEPRECATED. It now runs the default flow (which already stays silent when there is nothing to settle). Emit one line ---fast is deprecated; running the unified /lets:end (it auto-skips when there's nothing to settle).- then proceed as default. (Accepted for one release; removal is a follow-up.)
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.

end is a command published in the GitHub repository restarter/lets-workflow (17 stars, last pushed 9d ago), licensed MIT. It adds 52 tokens to every session and 3,813 once invoked, about $0.0003 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.

analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
