What is source-command-end-session?

An end-of-session command for a codebase: it checks the project, writes a handoff note, and records a Journal entry.

It helps run the repository close-check, save session handoff details, record the session in the Journal, and surface loose threads.

It gathers unfinished work and verification warnings in one closing routine, so the next session can understand the project state.

Token cost

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	$0.00030	$0.01613
Opus 5.5	$0.00012	$0.00645
Sonnet 5.5	$0.00006	$0.00323
Haiku 4.5	$0.00003	$0.00161

Security

Grade A, and why

source-command-end-session 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 2mo 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.

source-command-end-session

Use this skill when the user asks to run the migrated source command end-session.

Command Template

/end-session — verify, then write session artifacts + surface loose threads

Purpose: complete CLAUDE.md's Quick Session Checklist on Petter's behalf (AGENTS.md → "Session Checklists" carries the Codex-flavored pointer to the same list — AGENTS.md has no numbered checklist of its own, CLAUDE.md's is canonical). This command DOES write the handoff file and Journal entry — that's the standing preference (set 2026-04-27). It still does not create Decisions DB entries, To-do mutations, or other governance artifacts without explicit per-item approval.

Run these steps in order. After the checks, write the artifacts (steps 2 and 3) before producing the final report.

1. Run the codebase close-check script

cd apps/api && npx tsx --env-file=../../.env scripts/session-close-check.ts

Checks git integrity, DB↔code parity, stuck caps, open breakers, uncommitted handoff files. Exit codes: 0 clean, 1 warnings, 2 blockers. Capture findings for the final report.

2. Write the session handoff file (CLAUDE.md Quick Session Checklist step 7)

Author a handoff file at handoff/_general/from-code/YYYY-MM-DD-<topic>.md covering this session's work. Convention:

First line is Intent: summarizing what the session set out to do.
Body covers what shipped, what's open, non-obvious learnings, and cost (if any).
Topic slug should be specific enough that future-you can grep for it (e.g. x402scan-indexing-and-pr-cleanup, not cleanup).

If a handoff file authored this session already exists for today's topic (e.g. an earlier /go invocation already wrote one), don't duplicate — report its path. Only one handoff per topic per day; if the session covered two distinct topics, write two files.

If the session was genuinely trivial (single trivial fix, nothing worth recording), still write a one-line handoff. Skipping is Petter's call, not yours.

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.
