pantheon-forget

pantheon-forget is a command for Claude Code from ils15/pantheon-legacy. It costs 41 tokens per session (608 once invoked), scanned A, original, MIT.

A command that compresses old saved memories into shorter summaries. bioRxiv is not involved; these are notes retained by the agent about earlier work.

In plain words
What is it for?
Finding old memory entries by age or namespace, previewing them, and replacing groups of entries with summaries.
Why use it?
It reduces duplicate detail and keeps old memories easier to manage and search.

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

pantheon-forget 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 7d 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.

/pantheon-forget — Memory Range Compression

What: Applies range compression to old memory entries — groups entries by time period and namespace, generates a concise summary via fast LLM, replaces N raw entries with 1 summary. Companion to memory_consolidate (merge) vs memory_forget (compress).

Usage

/pantheon-forget                                    → Lista candidatas (7+ dias, modo interativo)
/pantheon-forget --days=30                          → Só entradas com 30+ dias
/pantheon-forget --namespace=sessions               → Namespace específico
/pantheon-forget --namespace=sessions --days=14     Combinado
/pantheon-forget --auto                             → Comprime sem confirmação
/pantheon-forget --auto --days=30 --compress         → Agressivo: 30+ dias + comprimir em 1 arquivo
/pantheon-forget --dry-run                          → Preview sem modificar

Flags

Flag Default Descrição
--days=<N> 7 Idade mínima em dias
--namespace=<ns> all Namespace específico
--auto off Comprimir sem confirmação
--dry-run off Preview sem modificar
--compress off Comprimir tudo em 1 único entry (modo agressivo)

How It Works

  1. memory_list() → obtém entradas, filtra por idade
  2. Agrupa por namespace + mês
  3. Cada grupo: envia para LLM fast com prompt:
    Summarize these N memory entries into 2-3 sentences:
    [entries...]
    
  4. Substitui grupo por entry único com key compressed:<namespace>:<YYYY-MM>
  5. Entradas originais são deletadas via memory_forget()

Output

🗜️ Memory Range Compression

Group: sessions · 2026-06 (15 entries · 1.2K tokens)
  → "Sessões de junho focadas em migração FastAPI, ajustes de rota e correção de testes."
  → Compressed: 15 → 1 entry ✅

Group: decisions · 2026-05 (8 entries · 640 tokens)
  → "Decisões de maio sobre arquitetura: monorepo mantido, SQLAlchemy 2.0 como padrão."
  → Compressed: 8 → 1 entry ✅

Summary: 2 groups compressed, 23 entries → 2 entries (-91%)
Tokens saved: ~1.8K

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.
