What is add-memory-kind?

A workflow for adding a new kind of business memory to EverOS, a framework that stores and retrieves useful information from work. It helps choose between readable text files, a database, and a search index, then connect the required parts.

Use it when adding a new persisted record type, such as a case, profile, playbook, or custom business entity.

It removes the guesswork involved in deciding where new information belongs and prevents the storage and writing code from getting out of sync.

How EverMind-AI/EverOS configures Claude Code

About the project

EverOS is a Python library and local-first memory runtime that gives AI agents a portable memory layer across apps, devices, and workflows. It stores conversations, files, and agent activity as readable Markdown while maintaining local indexes for retrieval and reuse. The catalogue add-ons provide commands, skills, hooks, and settings for using EverOS with coding agents.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.02973
Opus 5.5	$0.00022	$0.01189
Sonnet 5.5	$0.00011	$0.00595
Haiku 4.5	$0.00006	$0.00297

Security

Grade A, and why

add-memory-kind 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.

/add-memory-kind — Add a new business memory kind

When to invoke

Adding a new persisted business entity (Episode, Case, Skill, AtomicFact, Foresight, Profile, or something custom). Multiple storage layers may be involved; this skill walks the decision then the wiring.

1. Decide the storage combination

A memory kind does not have to use all three layers. Pick by what the kind actually needs:

Need	Markdown	SQLite	LanceDB
Human-readable / agent-editable source-of-truth text	✅
Structured state, ACID transactions, joins, predicates		✅
Vector / BM25 / hybrid retrieval			✅

Common combinations seen in EverOS:

Combo	Example	Rationale
md only	scratch notes / dump bins	text-of-truth, no index needed
md + lancedb	episode / memcell / case	text-of-truth + semantic retrieval
md + sqlite	profile / playbook / soul.md state	text-of-truth + structured state to query
md + sqlite + lancedb	full-blown business records	when you need both transactional state AND retrieval
sqlite only	audit log / task queue / LSN watermark	system state, never user-facing
lancedb only	rare; usually you still want md	derived embeddings without text-of-truth

Rule of thumb: markdown is the truth; sqlite and lancedb are derived indexes that can be rebuilt from md. Drop md only when the kind has no human-readable form (pure system state).

2. Pick the markdown storage strategy (if md is in your combo)

Three strategies — declared in the EverOS Markdown First spec:

Strategy	Filename	Mutation	Examples
Daily-log append	`<prefix>-YYYY-MM-DD.md`	append entries	memcell / episode / case / atomic_fact / foresight
Skill-named in-place	`skill_<name>.md`	overwrite the file	skills (procedural memory)
Single-file rewrite	`user.md` / `agent.md` / `soul.md` / `behaviors.md` / `tools.md`	overwrite the file	profiles / playbooks

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.
