A command for closing a Memex work session by updating memory files, refreshing affected indexes, and checking file links. A session-end hook is an automatic action that can run when a session finishes.

Use it when ending a session, before a long break, when the automatic closing action did not run, or when you want to force a clean checkpoint.

It leaves a current checkpoint for the next session and prevents broken links or unfinished memory updates from accumulating.

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	$0.00056	$0.02636
Opus 5.5	$0.00022	$0.01054
Sonnet 5.5	$0.00011	$0.00527
Haiku 4.5	$0.00006	$0.00264

Security

Grade A, and why

session-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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/verify-wikilinks.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memex - Session End

Wikilink rule: When referencing files in any markdown you write, use [[filename]] format. Plain-text filenames break Obsidian graph connectivity.

Leave the workspace clean for the next session. Work each step in order — no skipping, no asking permission between steps; execute everything, report at the end.

Session-end's work is proportional to the session (touched files, modified hubs, new decisions). Workspace-wide maintenance — graph rebuild, dedup, contradiction sweep, decisions compression — lives in /memex:reindex//memex:consolidate on their own cadence.

Step 1: Detect workspace and resolve paths

Run WORKSPACE_ROOT=$(pwd) && echo "$WORKSPACE_ROOT" via Bash.

No _MANIFEST.md: skip silently, stop. Otherwise resolve paths (first match wins): manifest config table → convention (memory/status.md, session-log.md, decisions.md, scratch/ideas.md or ideas.md) → search by name. No session lock — unconditional and idempotent.

Step 2: Synthesize the session

Before touching files, write a brief internal summary: files created/modified/moved, domains touched, decisions made, done vs. left open.

Step 3: Update status.md (idempotent)

Update "Last updated" to today
Remove completed items from "What's In Progress"
Update "What's Blocked" — resolve/add blockers
Update "Next Priorities" to reflect what's next

Idempotency check: strip the "Last updated" line from old and new content, hash both. Matching hashes (unchanged substance): skip the write entirely, including the date — prevents "ran twice" from compounding drift via timestamp churn.

Step 4: Write the session-log entry

Prepend to session-log.md (after the header, before existing entries):

## YYYY-MM-DD - [one-line title]

- [what changed - name files specifically]
- [decisions made or insights locked]
- [what's next / what was left open]

---

3-5 bullets. Past tense. Specific.

If the log now has more than 10 entries, archive the oldest — see references/log-rotation.md.

Changes

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.
