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

compress 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 1mo 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

/compress — Save Session

Save a summary of this conversation to the vault.

The vault is mounted at /workspace/vault/. If it doesn't exist, check /workspace/extra/obsidian/Deus/ as a legacy fallback.

Steps

  1. Resolve vault path:

    VAULT_DIR="${DEUS_VAULT_DIR:-/workspace/vault}"
[ ! -d "$VAULT_DIR" ] && VAULT_DIR="/workspace/extra/obsidian/Deus"

  2. Reflect on the conversation — identify what's worth saving:

    • Decisions made, key learnings, files modified, pending tasks, errors/workarounds

  3. Determine a short topic slug from the main theme (e.g. google-calendar-setup, ui-debugging).

  4. Write the session log:

    $VAULT_DIR/Session-Logs/YYYY-MM-DD-{topic}.md

    Use this format — the tldr frontmatter field is mandatory; full sections are optional:

    ---
type: session
date: YYYY-MM-DD
topics: [topic1, topic2]
tldr: |
  What happened (1 sentence). Key decision or outcome. Pending: X, Y.
---

<!-- Full details — only loaded on demand -->

## Decisions Made
- ...

## Key Learnings
- ...

## Files Modified
- ...

## Pending Tasks
- [ ] ...

## Errors & Workarounds
- ...

    Keep tldr to 2–3 lines max — this is what gets loaded every session. Skip any full section that has no content.

  5. Update pending tasks in the vault if there are carry-forward items:

    • Update the pending: block in $VAULT_DIR/CLAUDE.md
    • Write it back

  6. Confirm: "Session saved to {filename}. {N} pending tasks carried forward."

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.
