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 | $0.00346 |
| Opus 5 | $0.00013 | $0.00173 |
| Sonnet 5 | $0.00005 | $0.00069 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
crestapps-core-ai-memory 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
CrestApps.Core AI Memory - Prompt Templates
Add AI Memory
You are a CrestApps.Core expert. Generate code and guidance for long-term user memory in CrestApps.Core.
Guidelines
- Use memory for durable user-scoped facts, not transient chat state.
- Register memory through the AI suite builder.
- Add a durable store explicitly with Entity Framework Core or YesSql.
- Keep memory writes behind the safety pipeline.
- Pair memory with orchestration when relevant memories should be injected automatically.

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.

crestapps-core-ai-memory is a skill published in the GitHub repository CrestApps/CrestApps.AgentSkills (13 stars, last pushed 8d ago), licensed MIT. It adds 25 tokens to every session and 346 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 2026-08-30.
Other skills, from other repositories
setup-location-memory
Install or repair the location archive. Use when the location tools are missing, when they error on the database, when the user wants to import a Google Timeline export, when they want to start a live feed from OwnTracks, or when they ask to set up location memory.
lore-onboard
First-time setup wizard for LoreConvo. Verifies the MCP server is connected, the database is accessible, hooks are configured, and runs a test save/load cycle. Use when the user says "set up loreconvo", "onboard", "/lore-onboard", "verify loreconvo", "test loreconvo setup", or after first installing the plugin.
nlqdb-docs-memory
Turn this repo's markdown docs into a queryable nlqdb memory database — decision IDs and statuses, open questions with ages, queues, ledgers, and the cross-references between them. Use when asked which features have stale open questions, which decisions reference a given ID, what is blocked and since when, or to…
nlqdb-memory
Give this agent persistent, queryable memory over the nlqdb MCP server. Use whenever the agent needs to remember something across sessions, recall what it stored, or aggregate over its memory (GROUP BY / JOIN / counts / trends) — backed by a real Postgres it queries in plain English, not a vector store.
