# tenet ask

> Query project memory — decisions, patterns, history

Search your project's accumulated knowledge. Finds decisions, patterns, discoveries, and past work across all sessions.

## Usage

```bash theme={null}
tenet ask "why is the timeout 30s?"
tenet ask "what auth strategy did we choose?"
tenet ask "when did we last change the deployment config?"
```

## How It Works

1. Query goes through BM25 search across all indexed memories
2. Results ranked by relevance (term frequency, document frequency, recency)
3. Top results shown with source, date, and relevance score

## What It Searches

* **Journal entries** — decisions, features, fixes, discoveries from every session
* **Knowledge docs** — files in `knowledge/` directory
* **Code headers** — `@purpose` tags from source files
* **Manual memories** — notes added via `tenet_memory_add`

## Options

| Flag             | Description                                       |
| ---------------- | ------------------------------------------------- |
| `--type <type>`  | Filter by type: decision, feature, fix, discovery |
| `--since <date>` | Only search entries after this date               |
| `--limit <n>`    | Max results (default: 10)                         |

## Example Output

```
Found 3 relevant memories:

[decision] 2026-02-14
  Increased timeout from 5s to 30s after hub crashes under load.

[revert] 2026-01-28
  Tried 10s timeout — caused cascade failures in webhook processing.

[discovery] 2026-01-15
  P99 latency spikes to 22s during batch payroll runs.
```
