description: Pull a context pack from the live AtoCore service for the current prompt
argument-hint: <prompt text> [project-id]
---

You are about to enrich a user prompt with context from the live
AtoCore service. This is the daily-use entry point for AtoCore from
inside Claude Code.

The work happens via the **shared AtoCore operator client** at
`scripts/atocore_client.py`. That client is the canonical Python
backbone for stable AtoCore operations and is meant to be reused by
every LLM client (OpenClaw helper, future Codex skill, etc.) — see
`docs/architecture/llm-client-integration.md` for the layering. This
slash command is a thin Claude Code-specific frontend on top of it.

## Step 1 — parse the arguments

The user invoked `/atocore-context` with:

```
$ARGUMENTS
```

Treat the **entire argument string** as the prompt by default. If the
last whitespace-separated token looks like a registered project id or
alias (`atocore`, `p04`, `p04-gigabit`, `gigabit`, `p05`,
`p05-interferometer`, `interferometer`, `p06`, `p06-polisher`,
`polisher`, or any case-insensitive variant), pull it off and treat
it as an explicit project hint. The remaining tokens become the
prompt. Otherwise leave the project hint empty and the client will
try to auto-detect one from the prompt itself.

## Step 2 — call the shared client

Use the Bash tool. The client respects `ATOCORE_BASE_URL` (default
`http://dalidou:8100`) and is fail-open by default — if AtoCore is
unreachable it returns a `{"status": "unavailable"}` payload and
exits 0, which is what the daily-use loop wants.

**If the user passed an explicit project hint**, call `context-build`
directly so AtoCore uses exactly that project:

```bash
python scripts/atocore_client.py context-build \
  "<the prompt text>" \
  "<the project hint>"
```

**If no explicit project hint**, call `auto-context` which will run
the client's `detect-project` routing first and only call
`context-build` once it has a match:

```bash
python scripts/atocore_client.py auto-context "<the prompt text>"
```

In both cases the response is the JSON payload from `/context/build`
(or, for the `auto-context` no-match case, a small
`{"status": "no_project_match"}` envelope).

## Step 3 — present the context pack to the user

The successful response contains at least:

- `formatted_context` — the assembled context block AtoCore would
  feed an LLM
- `chunks_used`, `total_chars`, `budget`, `budget_remaining`,
  `duration_ms`
- `chunks` — array of source documents that contributed, each with
  `source_file`, `heading_path`, `score`

Render in this order:

1. A one-line stats banner: `chunks=N, chars=X/budget, duration=Yms`
2. The `formatted_context` block verbatim inside a fenced text code
   block so the user can read what AtoCore would feed an LLM
3. The `chunks` array as a small bullet list with `source_file`,
   `heading_path`, and `score` per chunk

Three special cases:

- **`{"status": "no_project_match"}`** (from `auto-context`)
  → Tell the user: "AtoCore could not auto-detect a project from the
  prompt. Re-run with an explicit project id:
  `/atocore-context <prompt> <project-id>` (or call without a hint
  to use the corpus-wide context build)."
- **`{"status": "unavailable"}`** (fail-open from the client)
  → Tell the user: "AtoCore is unreachable at `$ATOCORE_BASE_URL`.
  Check `python scripts/atocore_client.py health` for diagnostics."
- **Empty `chunks_used: 0` with no project state and no memories**
  → Tell the user: "AtoCore returned no context for this prompt —
  either the corpus does not have relevant information for the
  detected project or the project hint is wrong. Try a different
  hint or a longer prompt."

## Step 4 — what about capturing the interaction

Capture (Phase 9 Commit A) and the rest of the reflection loop
(reinforcement, extraction, review queue) are intentionally NOT
exposed by the shared client yet. The contracts are stable but the
workflow ergonomics are not, so the daily-use slash command stays
focused on context retrieval until those review flows have been
exercised in real use. See `docs/architecture/llm-client-integration.md`
for the deferral rationale.

When capture is added to the shared client, this slash command will
gain a follow-up `/atocore-record-response` companion command that
posts the LLM's response back to the same interaction. That work is
queued.

## Notes for the assistant

- DO NOT bypass the shared client by calling curl yourself. The
  client is the contract between AtoCore and every LLM frontend; if
  you find a missing capability, the right fix is to extend the
  client, not to work around it.
- DO NOT silently change `ATOCORE_BASE_URL`. If the env var points at
  the wrong instance, surface the error so the user can fix it.
- DO NOT hide the formatted context pack from the user. Showing
  what AtoCore would feed an LLM is the whole point.
- The output goes into the user's working context as background;
  they may follow up with their actual question, and the AtoCore
  context pack acts as informal injected knowledge.
