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 | $0.00064 | $0.00864 |
| Opus 5 | $0.00032 | $0.00432 |
| Sonnet 5 | $0.00013 | $0.00173 |
| Haiku 4.5 | $0.00006 | $0.00086 |
Grade A, and why
close-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 2d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/close-session — the end-of-session ritual
You close the session in four steps. Don't just dump — audit. Everything you write, you announce briefly; anything promoted to rules/concepts needs the user's verbal "yes" first.
Step 1 — Capture what's new
Scan this session for observations worth keeping. Append each to .claude/memory/MEMORY.md
as a ONE-LINE [YYYY-MM-DD]-prefixed entry. Short, scannable, no essays (long rationale
belongs in a concept article, step 2).
Step 2 — Audit & promote (the valuable part)
Read the date-tagged entries in MEMORY.md. Look for repetition: did this pattern appear on 3+ different dates? Surface 2-4 candidates, be specific: "noticed [date], [date], [date] you said X — codify as a rule or a concept article?"
- User says yes → write
knowledge/concepts/<topic>.md(facts + rationale; frontmatter perknowledge/index.mdspec) or.claude/rules/<name>.md(mechanical always/never constraint; only for patterns stable 6+ months). Updateknowledge/index.md(one line per concept). - Promoted or long-absorbed entries get PRUNED from MEMORY.md — that's how it stays under its caps (180 lines / 32 KB / 3000 chars per line).
- Writing a fact into a second place?
reference/doc-governance.md— one SSOT per fact, and when a fact changes you grep its restatements in the same pass. A product or architecture decision goes to the ledger instead —projects/<name>/decisions-log.md, format inreference/decisions-log.md. A plan, a spec, a research finding or a QA record is NOT memory: it belongs in that project's folder, per the map in itsREADME.md.
Step 3 — Refresh the MEMORY.md header
The header (everything above the first ---) is «current state of work», 2-3 sentences,
REPLACED every close — never a chronicle of past sessions. Per-session detail lives in the
handoff, not stacked in the header.
Step 4 — Write the handoff
Copy context/handoffs/HANDOFF-TEMPLATE.md → context/handoffs/<topic>-<YYYY-MM-DD>.md and
fill its five sections (what was done · where things stand · memory updates · next steps ·
opening note). The SessionStart hook injects the newest handoff next time — this file IS the
"remember where we left off" mechanism.
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.

close-session is a skill published in the GitHub repository awrshift/claude-memory-kit (31 stars, last pushed 6d ago), licensed MIT. It adds 64 tokens to every session and 864 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.
