## Important Notes
<!-- Add project-specific notes here -->
### DeepSeek-Specific Capabilities
This project is built specifically for DeepSeek models, leveraging their unique features:
**Thinking Tokens**: DeepSeek models can output thinking blocks (`ContentBlock::Thinking`) before providing final answers. The TUI supports streaming and displaying thinking tokens with visual distinction. You can use thinking tokens to reason step-by-step before committing to a response.
**Reasoning Models**: DeepSeek offers specialized reasoning models (e.g., `deepseek-reasoner`, `deepseek-r1`) that excel at step-by-step problem solving. Consider using these models for complex tasks.
**Large Context Window**: DeepSeek models have 128k context windows, allowing you to process large codebases. Use `project_map` and `file_search` to navigate efficiently.
**DeepSeek API**: The CLI uses DeepSeek's OpenAI‑compatible API with support for the Responses API endpoint. The base URL can be configured for global (`api.deepseek.com`) or China (`api.deepseeki.com`).
**Web Browsing**: For up‑to‑date information about DeepSeek models, documentation, or API changes, use `web.run` with citations. Example search: “DeepSeek API documentation”.
### Dogfooding Tips
As a DeepSeek model working on this project, you are “dogfooding” your own tool. Use this opportunity to:
- Test the toolset thoroughly and report any issues.
- Suggest improvements that would make DeepSeek models more effective.
- Keep changes small, focused, and well‑tested.
Remember to run `cargo test` and `cargo check` after any changes.

## [Unreleased]
## [0.3.16] - 2026-02-15
### Added
- `deepseek models` CLI command to fetch and list models from the configured `/v1/models` endpoint (with `--json` output mode).
- `/models` slash command to fetch and display live model IDs in the TUI.
- Slash-command autocomplete hints in the composer plus `Tab` completion for `/` commands.
- Command palette modal (`Ctrl+K`) for quick insertion of slash commands and skills.
- Persistent right sidebar in wide terminals showing live plan/todo/sub-agent state.
- Expandable tool payload views (`v` in transcript, `v` in approval modal) for full params/output inspection.
- Runtime HTTP/SSE API (`deepseek serve --http`) with durable thread/turn/item lifecycle, interrupt/steer, and replayable event timeline.
- Background task queue (`/task add|list|show|cancel` and `POST /v1/tasks`) with persistent storage, bounded worker pool, and timeline/artifact tracking.
### Changed
- Centralized the default text model (`DEFAULT_TEXT_MODEL`) and shared common model list to reduce drift across runtime/config paths.
- `/model` now clarifies that any valid DeepSeek model ID is accepted (including future releases), while still showing common model IDs.
### Fixed
- Expanded reasoning-model detection for chat history reconstruction (supports R-series and reasoner-style naming without hardcoding single versions).
- Aligned docs/config examples with actual runtime default model (`deepseek-v3.2`).

## Runtime API (HTTP/SSE)
`deepseek serve --http` starts a local runtime API for external clients.
Default bind: `127.0.0.1:7878`
Core endpoints:
- `GET /health`
- `GET /v1/sessions`
- `POST /v1/stream` (backward-compatible single-turn SSE wrapper)
- `POST /v1/threads`
- `GET /v1/threads`
- `GET /v1/threads/{id}`
- `POST /v1/threads/{id}/resume`
- `POST /v1/threads/{id}/fork`
- `POST /v1/threads/{id}/turns`
- `POST /v1/threads/{id}/turns/{turn_id}/steer`
- `POST /v1/threads/{id}/turns/{turn_id}/interrupt`
- `POST /v1/threads/{id}/compact`
- `GET /v1/threads/{id}/events` (SSE replay/live, optional `since_seq`)
- `GET /v1/tasks`
- `POST /v1/tasks`
- `GET /v1/tasks/{id}`
- `POST /v1/tasks/{id}/cancel`
Runtime semantics:
- explicit durable Thread/Turn/Item lifecycle with IDs and statuses
- multi-turn continuity on the same thread
- one active turn per thread (overlap rejected with `409`)
- interrupt transitions to terminal `interrupted` only after cleanup
- steer support for active turns
- compaction surfaced as first-class lifecycle items (`auto` + `manual`)
- replayable per-thread event timeline for API/TUI clients
Task queue semantics:
- durable task storage under `~/.deepseek/tasks` (override with `DEEPSEEK_TASKS_DIR`)
- restart-safe recovery (in-progress tasks are re-queued on startup)
- bounded worker pool via `deepseek serve --http --workers <1-8>`
- task execution linked to runtime thread/turn timelines
Security caveat:
- this server is local-first and assumes trusted local access
- no built-in auth/TLS/multi-user isolation
- do not expose it directly to untrusted networks without your own auth/proxy controls

### Runtime Thread/Turn Timeline
1. API/TUI creates or resumes a thread (`/v1/threads*`)
2. Turn starts on the thread (`/v1/threads/{id}/turns`)
3. Engine events are mapped to item lifecycle events (`item.started|item.delta|item.completed`)

5. Compaction (auto/manual) is emitted as `context_compaction` item lifecycle
6. Clients replay history and resume with `/v1/threads/{id}/events?since_seq=<n>`
### Durable Schema Gates
- `session_manager.rs`, `runtime_threads.rs`, and `task_manager.rs` embed `schema_version` on persisted records.
- On load, newer schema versions are rejected with explicit errors instead of silently truncating/overwriting data.
- This allows safe forward migrations and prevents corruption when binaries and stored state are out of sync.

2. **Tool safety**: Non-yolo mode requires approval for destructive operations
2. **Tool safety**: Non-yolo mode requires approval for destructive operations, including side-effectful MCP tools
3. **Extensibility**: MCP, skills, and hooks allow customization without code changes

# DeepSeek CLI Operations Runbook
This runbook covers practical debugging and incident response for the local CLI/TUI runtime.
## Quick Triage
1. Confirm binary + config:
- `cargo run -- --version`
- `cat ~/.deepseek/config.toml` (or inspect configured profile)
2. Enable verbose logs:
- `RUST_LOG=deepseek_cli=debug cargo run`
- For HTTP retries/reconnects: `RUST_LOG=deepseek_cli::client=debug cargo run`
3. Capture current state:
- `ls ~/.deepseek/sessions`
- `ls ~/.deepseek/sessions/checkpoints`
- `ls ~/.deepseek/tasks`
## Incident: Turn Hangs or Stream Stops
Symptoms:
- TUI remains in loading state
- partial assistant output with no completion
Checks:
1. Inspect retry/health logs (`deepseek_cli::client`)
2. Verify endpoint connectivity:
- `curl -sS https://api.deepseek.com/v1/models -H "Authorization: Bearer $DEEPSEEK_API_KEY"`
3. Confirm no local sandbox/permission deadlock in tool output
Actions:
1. Cancel current turn (`Esc` in TUI)
2. Retry prompt; if still failing, restart TUI
3. On restart, verify crash checkpoint recovery message appears
## Incident: Network Outage / Offline Behavior
Expected behavior:
- New prompts are queued while offline mode is active
- Queue state persists to `~/.deepseek/sessions/checkpoints/offline_queue.json`
Checks:
1. Open queue in TUI: `/queue list`
2. Confirm persisted queue file exists and updates timestamp
Actions:
1. Restore connectivity
2. Re-send queued entries (from `/queue edit <n>` + Enter, or normal input flow)
3. Ensure queue file clears when queue is empty
## Incident: Crash Recovery Needed
Expected behavior:
- Checkpoint stored at `~/.deepseek/sessions/checkpoints/latest.json`
- Startup auto-restores checkpoint when no explicit `--resume` target is supplied
Actions:
1. Start TUI normally and verify "Recovered checkpoint session" status
2. If automatic recovery fails, inspect checkpoint JSON for schema mismatch
3. If schema is newer than binary supports, upgrade binary or remove stale checkpoint
## Incident: Persistent State Schema Errors
Symptoms:
- Errors like `schema vX is newer than supported vY`
Affected stores:
- sessions (`~/.deepseek/sessions/*.json`)
- runtime thread/turn/item records
- tasks (`~/.deepseek/tasks/tasks/*.json`)
Actions:
1. Confirm binary version and migration expectations
2. Back up the state directory before editing
3. Either:
- run with a newer compatible binary, or
- archive incompatible records and regenerate state
## Incident: MCP/Tool Execution Failures
Checks:
1. Validate `~/.deepseek/mcp.json` schema and server command paths
2. Confirm server process can start manually
3. Check sandbox denials in TUI history / logs
Actions:
1. Retry with required approvals (or YOLO only when appropriate)
2. Temporarily disable failing MCP server and isolate issue
3. Re-enable after verification with `/mcp` diagnostics
## Post-Incident Checklist
1. Preserve logs and relevant state files
2. Record trigger, impact, and mitigation
3. Add or update regression tests (retry/recovery/schema)
4. Update this runbook and architecture docs if behavior changed

# Runtime API (HTTP/SSE)
DeepSeek CLI can expose a local runtime API for external clients:
```bash
deepseek serve --http --host 127.0.0.1 --port 7878 --workers 2
```
Defaults:
- bind: `127.0.0.1:7878`
- workers: `2` (clamped to `1..8`)
## Security Model (Local-First)
- The server is designed for trusted local use.
- There is no built-in auth, user isolation, or TLS termination.
- Do not expose this API directly to untrusted networks.
- If remote access is required, place it behind your own authenticated reverse proxy/VPN.
## Runtime Data Model
The runtime uses a durable Thread/Turn/Item lifecycle.
- `ThreadRecord`
- `id`, `created_at`, `updated_at`
- `model`, `workspace`, `mode`
- `latest_turn_id`, `latest_response_bookmark`, `archived`
- `TurnRecord`
- `id`, `thread_id`
- `status`: `queued|in_progress|completed|failed|interrupted|canceled`
- timestamps, duration, usage, error summary
- `TurnItemRecord`
- `id`, `turn_id`
- `kind`: `user_message|agent_message|tool_call|file_change|command_execution|context_compaction|status|error`
- lifecycle `status`: `queued|in_progress|completed|failed|interrupted|canceled`
The event log is append-only with global monotonic `seq` for replay/resume.
## Endpoints
### Health and Session
- `GET /health`
- `GET /v1/sessions?limit=50&search=<substring>`
### Compatibility Stream (Single Turn)
- `POST /v1/stream`
Backwards-compatible one-shot SSE wrapper. Internally creates an archived runtime thread+turn.
Request body:
```json
{
"prompt": "Summarize recent commits",
"model": "deepseek-v3.2",
"mode": "agent",
"workspace": ".",
"allow_shell": false,
"trust_mode": false,
"auto_approve": true
}
```
Typical SSE events:
- `turn.started`
- `message.delta`
- `tool.started`
- `tool.progress`
- `tool.completed`
- `approval.required`
- `sandbox.denied`
- `status`
- `error`
- `turn.completed`
- `done`
### Thread Lifecycle
- `POST /v1/threads`
- `GET /v1/threads?limit=50&include_archived=false`
- `GET /v1/threads/{id}`
- `POST /v1/threads/{id}/resume`
- `POST /v1/threads/{id}/fork`
Create thread request example:
```json
{
"model": "deepseek-v3.2",
"workspace": ".",
"mode": "agent",
"allow_shell": false,
"trust_mode": false,
"auto_approve": true,
"archived": false
}
```
### Turn Lifecycle
- `POST /v1/threads/{id}/turns`
- `POST /v1/threads/{id}/turns/{turn_id}/steer`
- `POST /v1/threads/{id}/turns/{turn_id}/interrupt`
- `POST /v1/threads/{id}/compact`
Notes:
- Only one active turn is allowed per thread (`409 Conflict` on overlap).
- `interrupt` returns quickly and marks `turn.interrupt_requested`.
- Terminal turn status becomes `interrupted` only after cleanup completes.
- Manual compaction is exposed as a turn with `context_compaction` item lifecycle events.
### Replayable Events
- `GET /v1/threads/{id}/events?since_seq=<u64>`
Returns SSE replay backlog, then live events for that thread.
SSE payload shape:
```json
{
"seq": 42,
"timestamp": "2026-02-11T20:18:49.123Z",
"thread_id": "thr_1234abcd",
"turn_id": "turn_5678efgh",
"item_id": "item_90ab12cd",
"event": "item.delta",
"payload": {
"delta": "partial output",
"kind": "agent_message"
}
}
```
Common event names:
- `thread.started`
- `thread.forked`
- `turn.started`
- `turn.lifecycle`
- `turn.steered`
- `turn.interrupt_requested`
- `turn.completed`
- `item.started`
- `item.delta`
- `item.completed`
- `item.failed`
- `item.interrupted`
- `approval.required`
- `sandbox.denied`
Compaction visibility:
- auto compaction emits `item.started`/`item.completed` with item kind `context_compaction` and `auto=true`
- manual compaction emits the same with `auto=false`
### Background Tasks
- `GET /v1/tasks`
- `POST /v1/tasks`
- `GET /v1/tasks/{id}`
- `POST /v1/tasks/{id}/cancel`
Tasks execute through the same runtime thread/turn pipeline and include:
- linked `thread_id` / `turn_id`
- runtime event count
- timeline + tool summaries + artifact references
## Persistence
Runtime store (default under task data root):
- `runtime/threads/*.json`
- `runtime/turns/*.json`
- `runtime/items/*.json`
- `runtime/events/{thread_id}.jsonl`
- `runtime/state.json` (monotonic sequence)
Task store:
- default `~/.deepseek/tasks` (override with `DEEPSEEK_TASKS_DIR`)
Both runtime and task state are restart-safe.
