hmem-consolidate is a skill for Claude Code, Codex from Bumblebiber/hmem. It costs 31 tokens per session (351 once invoked), scanned A, original, MIT.

A procedure for merging multiple hmem session checkpoints into one final summary. Checkpoints are saved progress notes created during a session.

In plain words
What is it for?
Use it when ending a session that created at least two checkpoints, or when the user runs /consolidate.
Why use it?
It turns several temporary summaries into one compact record without deleting the original checkpoint notes.

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

hmem-consolidate 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 9d 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.

What it actually says

hmem-consolidate

TRIGGER

Run when:

  • The session is ending AND hmem-checkpoint ran 2 or more times
  • User types /consolidate

Do NOT run if there was only one checkpoint — that summary is already final.

STEP 1: Read the O-Entry

Call read_memory on the active O-Entry:

read_memory(id: "O00XX", depth: 2)

Replace O00XX with the active O-Entry ID (P0056 → O0056).

Identify all child nodes with titles starting with "Summary YYYY-MM-DD". Collect their content.

STEP 2: Write merged summary

From all collected summaries, write ONE final summary with max 10 bullets:

  • Each bullet names a specific decision, file, command, or outcome
  • Never write "discussed X" or "made progress on Y"
  • Cover: main topic, decisions made, what changed, next step

STEP 3: Append to O-Entry

append_memory( id: "O00XX", content: "Final Summary <today's date e.g. 2026-04-24>\n\n- <bullet 1>\n- <bullet 2>\n...\n- " )

Do NOT delete or overwrite the individual checkpoint summaries.

OUTPUT

[CONSOLIDATED] Final summary written to O-Entry O00XX.

  • <bullet 1>
  • <bullet 2> ... [/CONSOLIDATED]

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.
