+
+One command deploys the mnemon skill, a `mem` shim, and a single `app.ready`
+hook to `~/.config/alma/`. Alma's hook stdout is not injected into the model
+context — only `decision`, `reason`, and `updatedInput` from the last JSON line
+are consumed — so the integration is deliberately shaped differently from the
+lifecycle-hook targets: the hook does one job (refresh a generated block inside
+`MEMORY.md`, which Alma already injects into its system prompt every request),
+and recall is left to the model through the skill. The block is delimited by
+`<!-- mnemon:begin -->` / `<!-- mnemon:end -->` and everything outside those
+markers is preserved byte for byte, because Alma's own prompt tells the model to
+write to the same file.
+
+Alma has no project-local hook configuration, so this target is user-global
+only.

 DeepSeek Harness (DSH) integrates through the [dsh-mnemon](https://github.com/omdsh-dev/dsh-mnemon) plugin, which layers DSH's runtime memory, managed project documents, and Mnemon's long-term memory spaces into one supervised three-tier memory system.

+name: mnemon
+description: Cross-tool long-term memory backed by mnemon. Recall before answering anything that depends on past decisions, preferences, or project context, and store durable facts the user will expect you to remember. Triggers include "记不记得 / 之前 / 上次 / 我们说过 / do you remember / we discussed".
+always-inject: true
+---
+
+# mnemon
+
+mnemon is the source of truth. Alma's own `memory/YYYY-MM-DD.md` notes are a
+per-session log, not the long-term store; durable facts belong in mnemon.
+
+## Use the shim, not the raw CLI
+
+`~/.config/alma/mnemon-bridge/mem` is the only supported entry point. It pins the
+store, keeps reads read-only, resolves short ids, and owns the `MEMORY.md` block.
+Call it with Bash:
+
+```bash
+MEM=~/.config/alma/mnemon-bridge/mem
+
+$MEM find "<query>" [--limit 5] [--chars 240] [--cat preference|decision|fact|insight|context]
+$MEM save "<content>" --cat decision --imp 4 [--tags a,b] [--entities X,Y] [--source user|agent]
+$MEM show <id-prefix>
+$MEM related <id-prefix> [--edge causal|entity|semantic|supersedes|temporal]
+$MEM recent [N]
+$MEM status
+```
+
+Calling `mnemon` directly is only correct when the shim is missing. The raw CLI
+needs a full UUID for `show`/`related`/`forget`, does not share the shim's store
+pinning, and its `recall --cat` flag is accepted but ignored in 0.2.13.
+
+## Recall
+
+Do **not** query on every turn. A recall costs 0.3–1.2 s and most turns do not
+need one. Recall when:
+
+- the user asks "记不记得 / 之前 / 上次 / 我们说过 / do you remember"
+- the topic switches to a specific project, service, repo, or host
+- the user names something you do not recognise but that clearly comes from
+  their history
+- you are about to make a decision that may already have been made
+
+Skip it for greetings, small talk, self-contained code questions, and any turn
+where the user already supplied the context.
+
+Use the result silently. Do not narrate "I checked my memory".
+
+## Remember
+
+Store one claim per entry, self-contained enough to make sense months later
+(with dates, file names, numbers). A conversation usually yields 0–3 durable
+entries; store nothing rather than padding the store.
+
+| kind | example | `--cat` | `--imp` |
+|---|---|---|---|
+| user preference | wording, taste, working style | `preference` | 4 |
+| decided course | "use A not B, because …" | `decision` | 3–5 |
+| durable technical fact | root cause, config shape, measured number | `insight` / `fact` | 3–4 |
+| project background | what a module currently is | `context` | 3 |
+
+`--cat` is mandatory and `general` is rejected: it is the default that turns into
+noise. Reserve `--imp 5` for facts that should be visible in every session.
+
+Never store secrets, tokens, passwords, or transient state that a command can
+recompute.
+
+## MEMORY.md ownership
+
+Alma injects `~/.config/alma/MEMORY.md` into the system prompt on every request,
+and Alma's own instructions tell the model to write to that same file. mnemon
+therefore owns exactly one region of it:
+
+```text
+<!-- mnemon:begin -->
+...
+<!-- mnemon:end -->
+```
+
+Never write outside those markers, and never edit inside them by hand — use
+`mem save` and let `prime.sh` regenerate the block. Everything outside the
+markers belongs to Alma and the user.
+
+Keep the block small. It is re-sent on every single turn; treat anything past a
+few KB as a permanent cost.
+
+## Guardrails
+
+- Categories: `preference` · `decision` · `insight` · `fact` · `context`
+- Edge types: `temporal` · `semantic` · `causal` · `entity` · `supersedes`
+- Max 8,000 chars per insight.
+- No cross-store queries; `--store "a,b"` is rejected. Query twice and merge.
+- Do not create new stores to separate topics.
