Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00476 |
| Opus 5 | $0.00016 | $0.00238 |
| Sonnet 5 | $0.00007 | $0.00095 |
| Haiku 4.5 | $0.00003 | $0.00048 |
Grade A, and why
compress scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/compress — Save Session
Save a summary of this conversation to the vault.
The vault is mounted at /workspace/vault/. If it doesn't exist, check /workspace/extra/obsidian/Deus/ as a legacy fallback.
Steps
-
Resolve vault path:
VAULT_DIR="${DEUS_VAULT_DIR:-/workspace/vault}" [ ! -d "$VAULT_DIR" ] && VAULT_DIR="/workspace/extra/obsidian/Deus" -
Reflect on the conversation — identify what's worth saving:
- Decisions made, key learnings, files modified, pending tasks, errors/workarounds
-
Determine a short topic slug from the main theme (e.g.
google-calendar-setup,ui-debugging). -
Write the session log:
$VAULT_DIR/Session-Logs/YYYY-MM-DD-{topic}.mdUse this format — the
tldrfrontmatter field is mandatory; full sections are optional:--- type: session date: YYYY-MM-DD topics: [topic1, topic2] tldr: | What happened (1 sentence). Key decision or outcome. Pending: X, Y. --- <!-- Full details — only loaded on demand --> ## Decisions Made - ... ## Key Learnings - ... ## Files Modified - ... ## Pending Tasks - [ ] ... ## Errors & Workarounds - ...Keep
tldrto 2–3 lines max — this is what gets loaded every session. Skip any full section that has no content. -
Update pending tasks in the vault if there are carry-forward items:
- Update the
pending:block in$VAULT_DIR/CLAUDE.md - Write it back
- Update the
-
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.

compress is a skill published in the GitHub repository sliamh11/Deus (51 stars, last pushed 4d ago), licensed MIT. It adds 33 tokens to every session and 476 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

memcord
Privacy-first, self-hosted chat memory for OpenClaw — save and recall conversation history across sessions without any cloud dependency.

cortex
Personal knowledge compiler and memory system. Ingests raw sources (documents, notes, transcripts, captures) into a structured, interlinked knowledge base. Maintains living entity pages, learning analysis, and the MEMORY.md routing table. Replaces the librarian skill.
librarian
DEPRECATED — Use the cortex skill instead. Cortex v2 absorbs all librarian functionality (memory maintenance, knowledge organization, learning analysis) into a unified knowledge compiler. This skill is kept for backwards compatibility but all triggers now route to Cortex.
neuron-curated-memory
Use Neuron (the semantic-memory MCP server) the RIGHT way so its graph stays clean and useful. Before answering, load prior context; after answering, save a CURATED turn — 3-5 concept keywords (nouns/entities/tech, never verbs or filler), typed links with a short rationale, and never a self-link.
