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.

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 | $0.00025 | $0.00382 |
| Opus 5 | $0.00013 | $0.00191 |
| Sonnet 5 | $0.00005 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
mempalace_manager 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
mempalace_manager
Abstract memory API — backend-neutral wrapper.
Operations
mem.put(partition, key, value, metadata?)mem.get(partition, key)mem.query(partition, filter)mem.search(partition, query, top_k)— semanticmem.delete(partition, key)mem.list(partition, prefix)mem.compact(partition)— AAAK recompressionmem.snapshot(partition, path),mem.restore(partition, path)mem.with_project(id, fn)— scoped accessmem.lift(key)— explicit global read from local context (logged)
I/O Contract
io_contract:
input: { op, partition, args }
output: { result }
idempotent: depends
side_effects: [fs]
Safety
- Partition scoping enforced — cross-scope reads require
with_project()orlift(). - Constitutional invariant:
isolation_strictcannot be disabled. - Selects backend via
memory.config.backend(mempalace|sqlite|filesystem|custom).
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.

mempalace_manager is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 2d ago), licensed Apache-2.0. It adds 25 tokens to every session and 382 once invoked, about $0.0001 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 2026-08-31.
