<skill name="kortix-memory">

<overview>
Every Kortix project has a **project brain** at `.kortix/memory/` — a
folder of curated markdown files describing what this project is,
which connections it uses, the conventions the team works by, and
the decisions worth not re-litigating.

`MEMORY.md` is the **index**. Memory is **not** auto-injected into the
prompt — the **memory protocol** is: at the start of a task, `view`
`.kortix/memory` with the `memory` tool to read the index and recover
prior context, then `view` the sub-files (`overview.md`,
`connections.md`, etc.) the index points at when they're relevant.
Record anything durable as you go — your context window may reset at
any time, so what isn't written to `.kortix/memory/` is lost.

Memory is **continuously CRUD'd**:

- Regular sessions add or update memory whenever they discover
  something durable worth keeping.
- The `harness-reflector` agent (`.kortix/opencode/agents/harness-reflector.md`)
  runs on a cron, surveys recent activity, and curates the folder as the
  memory pass of the `kortix-harness-refinement` protocol.
- Both consult this skill for the rubric.

Memory is **team-shared**: it lives in the repo, every session sees the
same content. Edits land on `main` only via a Kortix change request —
never by pushing directly.
</overview>

<when-to-load>
Load this skill when you:

- Discover a project convention, connection detail, decision, or
  workaround that should outlast this session
- Notice the project brain is out of date or contradicts current code
- Are the `harness-reflector` agent running the memory pass of your
  scheduled reflection run
- Want to know if something is worth writing down (use the rubric below)
- Need to add, rename, split, or delete a memory file
- Want to know how memory edits reach `main`

Skip this skill for one-off questions about *operating* code. Project
memory is about durable knowledge, not session state.
</when-to-load>

<file-layout>
```
.kortix/memory/
├── MEMORY.md           Index. `view` this first. One line per sub-file.
├── overview.md         What this project IS — purpose, shape, stakeholders.
├── connections.md      Third parties, MCP servers, channels, and connectors.
├── conventions.md      Coding patterns, naming, do / don't, style decisions.
└── decisions.md        Architectural and business decisions worth not re-debating.
```

Add new files freely when a topic deserves its own page (one topic per
file, kebab-case filename). **Always** keep `MEMORY.md` in sync — one
line per sub-file, format:

```
- [filename.md](filename.md) — one-line hook of what's inside
```

Don't move content out of `MEMORY.md` if it's a single line that
already lives in the index — keep that one line. Sub-files exist when
there's enough depth to warrant a click.
</file-layout>

<rubric>

### What to remember (KEEP)

- **The project's purpose** — what we're building, for whom, and the
  one-sentence pitch.
- **Architecture-level decisions** — why we use X over Y, which
  service owns what, the data flow.
- **Connection details** — which third parties / MCP servers /
  channels are wired, what credentials they need, how they're scoped.
- **Conventions** — naming, code style, branching, review norms — the
  stuff that's *de facto* across the codebase but not stated.
- **Workarounds and quirks** — known env issues, ordering constraints,
  flaky dependencies, gotchas that bit us once.
- **Ops runbooks** — how to deploy, how to roll back, how to debug the
  thing that breaks every quarter.
- **Glossary** — domain terms specific to this project that an
  outsider wouldn't know.
- **People & ownership** *(optional)* — who owns which surface, how to
  reach them, what they care about.

### What NOT to remember (DROP)

- One user's personal preferences — those are not project memory.
- Facts derivable from the repo layout, file names, or `git log`.
- One-off task state that won't matter next week.
- Anything that's already in `kortix.yaml`, `AGENTS.md`, or a SKILL.md.
- Secrets, tokens, API keys, PII — those live in the Kortix Secrets
  Manager, never in memory files.
- Speculation about future plans. Memory describes what *is*, not
  what might be.

### Style for entries

- **Plain prose** with short sentences.
- **State facts, not narratives** — "The web app talks to Supabase
  Postgres for auth" beats "We decided to use Supabase…".
- **Cite file paths** when the fact maps to code: `path/file.ts:120`.
- **Date hard-to-verify facts** in `YYYY-MM-DD` so readers can judge
  staleness.
- **Prefer editing existing entries** over piling new ones on. A
  bloated file is worse than a tight one.

</rubric>

<writing>

### The `memory` tool

Use the dedicated **`memory` tool** for everything under
`.kortix/memory/` — not the generic `read` / `edit` / `write` tools.
It's a 1:1 port of Anthropic's memory tool, sandboxed to the memory
folder, with the same six commands:

| command | what it does |
|---|---|
| `view` | List the memory dir (2 levels) or read a file with line numbers (optional `view_range`). **Run this first, every task.** |
| `create` | Create a new file (`path`, `file_text`). Errors if it already exists. |
| `str_replace` | Replace a **unique** snippet (`path`, `old_str`, `new_str`). |
| `insert` | Insert text at a line (`path`, `insert_line`, `insert_text`). |
| `delete` | Remove a file or directory (`path`). |
| `rename` | Move/rename (`old_path`, `new_path`). Won't overwrite. |

Paths are repo-relative and must start with `.kortix/memory`
(e.g. `.kortix/memory/overview.md`). Writes go straight into the real
`.kortix/memory/` folder, so they show up in the working tree and land
on `main` through the normal change-request flow (below).

1. `view` `.kortix/memory` to see what's there.
2. Identify the right file. Most additions fit `overview.md`,
   `connections.md`, `conventions.md`, or `decisions.md`. `create` a
   new file only when a topic deserves its own page.
3. Edit with `str_replace` / `insert`. Keep entries short, factual, and
   consistent with the surrounding prose.
4. If you added, renamed, or deleted a file, update `MEMORY.md` so the
   index matches the folder. The index is the table of contents every
   agent reads first — keep it accurate.
5. If something turned out to be wrong, `delete` it. Don't leave stale
   facts to confuse future agents.

### Landing memory on `main`

Session branches die when sessions end. Memory edits reach `main`
only via a Kortix change request — same path as any code change:

```sh
git add .kortix/memory
git commit -m "memory: <one-line summary of what changed>"
git push origin HEAD
kortix cr open \
  --title "memory: <one-line summary>" \
  --description "What changed and why."
```

The user reviews and merges. Don't merge your own CR.

</writing>

<reflector>

Scheduled memory curation is the fourth pass of the `harness-reflector`
agent (`.kortix/opencode/agents/harness-reflector.md`) — the
continual-harness loop. On that pass it:

1. Loads this skill.
2. Surveys recent project activity (git log since last run, recent
   merged CRs, session digests via `kortix sessions digest`).
3. Decides what's worth keeping per the **rubric** above.
4. CRUDs `.kortix/memory/` accordingly.
5. Folds the memory edits into its single `harness: …` CR.
6. Leaves memory untouched when nothing is worth changing.

To change *what gets remembered*, edit the **rubric** section of this
skill's project copy. The reflector reads it fresh every run, so a
merged CR to this file takes effect on the next reflection.

To change *when the reflector runs*, edit the `triggers:` entry
named `harness-reflector` in `kortix.yaml`. The cron sweep picks up
changes within a few seconds of the CR merging.

</reflector>

<gotchas>

- **The index is read first; sub-files are on demand.** Don't dump
  every fact into `MEMORY.md` — keep it a clean table of contents and
  push depth into sub-files the agent `view`s only when relevant.
- **`view` your memory before you start.** Nothing is auto-injected;
  if you skip the `view`, you work blind to what the project already
  knows. The `memory` tool's description and the agent rules say the
  same thing — this is the memory protocol.
- **Memory files are markdown, not databases.** Avoid heavy
  formatting, tables of 50 rows, or auto-generated content. If you
  catch yourself writing a script to generate a memory file, that
  content probably belongs in code, not memory.
- **Memory edits must go through CR.** Direct pushes to `main` bypass
  the user-review contract — the same rule as code. The reflector
  agent enforces this by always ending with `kortix cr open`.
- **Don't put secrets in memory.** Memory is read into context and
  committed to the repo. Secrets, tokens, API keys, and PII belong in
  the Kortix Secrets Manager, surfaced as env vars at runtime — not in
  `.kortix/memory/`.
