end-session

end-session is a skill for Claude Code, Codex from satsilem/ai-workflow-framework. It costs 85 tokens per session (2,303 once invoked), scanned A, original, MIT.

A session-closing workflow that records what happened in a coding session and identifies follow-up actions. It can present the report step by step or all at once in quick mode.

In plain words
What is it for?
Use it to review project notes and task files, summarize completed work, record gotchas, and prepare the next session.
Why use it?
It prevents decisions, unfinished work, and important warnings from being lost when the session ends.

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.

Security

Grade A, and why

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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.

End Session

The goal is to close the session cleanly — capture what happened, update the project files, and surface anything worth remembering or acting on next time.

Two modes:

  • Default — sequential: each section is presented one at a time, wait for confirmation before moving to the next.
  • Quick mode — triggered when the user says "end session quick" or "quick end session": present all sections in one report, user replies once.

If mode is unclear, use default (sequential).

Step 1 — Read current state

Before producing the report, read:

  • SESSION.md — to understand what's already logged and what gotchas exist
  • TODO.md — to know the current task list
  • CLAUDE.md — to check if anything critical needs updating
  • .reference/INDEX.md — if present, to align on existing evergreen reference docs

Also review the full conversation history — this is the source of truth for what actually happened this session.

Step 2 — Produce the end-session report

Default mode (sequential)

Present each section one at a time. Wait for the user's reply before moving to the next. Order:

  1. Summary — show first, no confirmation needed, then immediately show Gotchas
  2. Gotchas to add to SESSION.md → wait for reply
  3. Tasks to mark as done → wait for reply
  4. Suggested new tasks → wait for reply
  5. INSIGHTS.md suggestions → wait for reply
  6. Apply all confirmed changes

Quick mode (all at once)

If the user said "end session quick" — present all sections in one block, user replies once for all sections. Same structure, same numbered lists.

In quick mode, start with a compact summary table before the detailed sections:

Category Count Notes
Gotchas to add N include metadata tags
Tasks to mark done N include confidence tags
Suggested new tasks N deduped vs TODO.md
INSIGHTS suggestions N deduped vs INSIGHTS.md
Files to edit N SESSION.md / TODO.md / INSIGHTS.md

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.
