Correct the Tier 2 trigger.

skills/remember/SKILL.md now runs agent-memory brief before capture. Tier 2 therefore runs for remember as well as recall. Replace “only when recall fires” with wording that includes both paths.

it runs per invocation when either the remember or recall path triggers,
replacing the recall-only wording while preserving the existing tier

```

Tier 1 is loaded into every chat whether or not memory is ever used, so it has to read
like a description rather than a document. It is composed from constraint count, then
repos by note count, then topics by edge degree — and on overflow it sheds the
like a description rather than a document. `recall`'s is composed from constraint count,
then repos by note count, then topics by edge degree — and on overflow it sheds the
lowest-degree topics first, then repos, **one whole item at a time**. Cutting mid-word
would leave the description looking corrupted, which is worse than saying less.

Two pieces are structural and never dropped: the constraint count, and the closing
"use when" clause — which is the entire reason an agent decides to invoke at all.

**Tier 1 has two occupants.** `recall`'s description advertises what the store knows;
`remember`'s advertises what it is missing. The second is `captureGap` — the distance
in commits from HEAD to the nearest capture, which the store has always been able to
compute — routed to the one surface that is loaded at the moment capture is worth
doing. Before 0.7 it went only to `doctor`, a command run by the person who least
needed telling.

It is written as a *state*, never as an instruction: "340 commits since anything was
captured here" is a fact the model can weigh against what just happened in the
conversation, where "remember to capture things" is wallpaper it stops seeing. Code
supplies the timing signal; the model still decides whether anything durable happened.
On a covered repository it goes quiet and simply reports the count — a line that nags
at a current store teaches the reader to discount it before the day it matters.

Neither tier costs a premium request. A request is charged per prompt, not per tool
call, so both ride inside a turn that was already paid for.

## Step 0 — Read what is already known (ONE terminal call)

```bash
agent-memory brief
```

Read-only, safe on every shell including PowerShell, and it costs no request of its
own — it rides inside the turn you are already answering.

It answers three things you would otherwise guess at:

- **What is already here.** Deduplication is by exact content, so the same claim in
different words becomes a second node. If the brief already lists it, either say
nothing or update that note by its id.
- **Which ids are real.** An `edges[].dst` or `supersedes` pointing at an id you
invented is accepted and then silently never connects. Take targets from the brief.
- **Which types are empty.** A store with no `constraint` has not recorded what the
environment forbids, which is the type that saves a future session a wasted retry.

If the brief lists an id under "already covered", that juncture was captured minutes
ago. Do not capture it again.

Skip this step only when the user named exactly what to write and it is plainly new.
