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

alive-history 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

Session History

Search squirrel entries and logs for past session context.

Sources

  1. Squirrel entries -- .alive/_squirrels/*.yaml (session metadata, stash, recovery state)
  2. Log entries -- _kernel/log.md (decisions, narrative, signed entries)
  3. Stash file -- .alive/stash.json (unrouted items from sessions)

If the user asks about a specific walnut:

# Read that walnut's log
cat "$ALIVE_WORLD_ROOT/[walnut_path]/_kernel/log.md"

# Find squirrel entries for that walnut
grep -l "[walnut_name]" "$ALIVE_WORLD_ROOT/.alive/_squirrels/"*.yaml 2>/dev/null

If the user asks about a topic or person:

# Search all logs
grep -rl "[query]" "$ALIVE_WORLD_ROOT"/*/_kernel/log.md "$ALIVE_WORLD_ROOT"/*/*/_kernel/log.md 2>/dev/null

# Search squirrel entries
grep -rl "[query]" "$ALIVE_WORLD_ROOT/.alive/_squirrels/"*.yaml 2>/dev/null

If the user asks about recent sessions:

# List recent squirrel entries by date
ls -lt "$ALIVE_WORLD_ROOT/.alive/_squirrels/"*.yaml 2>/dev/null | head -10

Display

Recent sessions for [walnut/topic]:

[date] -- squirrel:[id] ([engine])
  Walnut: [name]
  Bundle: [bundle or none]
  Summary: [from log entry or recovery_state]
  Stash: [N] items ([routed/unrouted])

[date] -- squirrel:[id] ([engine])
  ...

Load full log entry?
  1. [session id] -- [date]
  2. [session id] -- [date]
  3. Search for something else

Escalation

If the user needs deeper context extraction from session transcripts, suggest /alive-mine for heavy mining.

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.
