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

timeline-report 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.

What it actually says

timeline-report: What Happened When

Turns raw observations into a readable narrative of work done across sessions.

Generating a Timeline

# Last 24 hours
python3 {SKILL_DIR}/scripts/memory_store.py timeline --hours 24 --limit 50

# Last week
python3 {SKILL_DIR}/scripts/memory_store.py timeline --hours 168 --limit 100

# All time (recent first)
python3 {SKILL_DIR}/scripts/memory_store.py stats  # check oldest date first
python3 {SKILL_DIR}/scripts/memory_store.py timeline --hours 9999 --limit 200

Report Format

Group observations by session, then by day. Format as:


[Session — Date] Project: <project>

  • Decision:
  • File edits:
  • Insights:
  • Errors fixed:
  • Summary:

Semantic Timeline (Topic-Based)

Instead of chronological, search for a topic across all time:

COWORK_MEM_DB=~/mnt/.claude/.cowork-mem/memory.db \
python3 {SKILL_DIR}/scripts/vector_search.py "<topic>" --limit 20

This answers "what happened with authentication across all sessions" better than a pure timeline.

Export for Sharing

python3 {SKILL_DIR}/scripts/memory_store.py export --format md > /tmp/memory-export.md

Produces full markdown export suitable for sharing with teammates or saving to Drive.

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.
