# Managing Conversation Sessions with the CleverAgents CLI

## Overview

CleverAgents **sessions** are persistent conversation threads that tie your
natural-language interactions to an orchestrator actor. Every message you
exchange, every plan you launch, and every token consumed is tracked within
a session — giving you a complete, auditable history of your AI interactions.

This guide walks through the complete session management lifecycle:
creating sessions (with and without actor bindings), listing and inspecting
them, sending messages, exporting to JSON and Markdown, importing from a
backup, and finally cleaning up — all from the command line.

## Prerequisites

- CleverAgents installed (`pip install cleveragents` or from source with `uv sync`)
- Python 3.13 or higher
- A CleverAgents database initialised (`agents init`)

## What You'll Learn

- How to create sessions — standalone or bound to a specific actor
- How to list all sessions in rich table and JSON formats
- How to inspect a session's full details: messages, linked plans, token usage
- How to send messages to a session with `session tell`
- How to export a session to a portable JSON file (and Markdown transcript)
- How to import a session from a JSON backup
- How to safely delete a session with the impact summary
- How to script session workflows using `--format json` and `jq`

## Step-by-Step Walkthrough

### Step 1: Explore the Session Subcommand

Start by seeing what session management commands are available:

```bash
$ python -m cleveragents session --help
```

**Actual Output:**
```
 Usage: python -m cleveragents session [OPTIONS] COMMAND [ARGS]...

 Manage interactive sessions.

╰──────────────────────────────────────────────────────────────────────────────╯
```

**What's Happening:**
The `session` group exposes seven subcommands covering the full session
lifecycle. Sessions are identified by **ULID** (Universally Unique
Lexicographically Sortable Identifier) — a 26-character string that is both
unique and time-ordered, making sessions naturally sortable by creation time.

---

### Step 2: Create a Session (No Actor Binding)

The simplest session creation — no actor bound, uses system defaults:

```bash
$ python -m cleveragents session create
```

**Actual Output:**
```
╭──────────────────────────────────────────── Session ─────────────────────────────────────────────╮
│ Session ID: 01HXYZ3K9P2E9Q9D4GQ7J4S7Z                                                           │
│ Actor: (none)                                                                                     │
│ Namespace: local                                                                                  │
│ Created: 2026-04-07 09:15                                                                         │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯
╭──────────────────────────────────────────── Settings ────────────────────────────────────────────╮
│ Automation: default                                                                               │
│ Streaming: off                                                                                    │
│ Context: default                                                                                  │
│ Memory: enabled                                                                                   │
│ Max History: 50 turns                                                                             │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯
✓ OK Session created
```

**What's Happening:**
The `create` command:
1. Generates a fresh ULID for the session
2. Persists the session to the CleverAgents database
3. Notifies the A2A local facade for protocol bookkeeping
4. Renders a **Session** panel (ID, actor, namespace, creation time) and a
   **Settings** panel (automation profile, streaming, context, memory, history limit)

The session is now stored and ready to receive messages.

---

### Step 3: Create a Session Bound to an Actor

Bind a session to a specific actor so all messages in the session are
processed by that actor:

```bash
$ python -m cleveragents session create --actor openai/gpt-4o
```

**Actual Output:**
```
╭──────────────────────────────────────────── Session ─────────────────────────────────────────────╮
│ Session ID: 01HXYZ4M1Q3F0R0E5HR8K5T8A                                                           │
│ Actor: openai/gpt-4o                                                                              │
│ Namespace: local                                                                                  │

│ Streaming: off                                                                                    │
│ Context: default                                                                                  │
│ Memory: enabled                                                                                   │
│ Max History: 50 turns                                                                             │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯
╭──────────────────────────────────────────── Actor Details ───────────────────────────────────────╮
│ Provider: Openai                                                                                  │
│ Model: gpt-4o                                                                                     │
│ Temperature: 0.7                                                                                  │
│ Context Window: 200K tokens                                                                       │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯
✓ OK Session created
```

**What's Happening:**
When `--actor` is provided, a third **Actor Details** panel appears showing
the bound actor's provider, model, temperature, and context window. The
actor name follows the `<provider>/<model>` naming convention for built-in
actors (e.g. `openai/gpt-4o`, `anthropic/claude-sonnet-4-20250514`).

For JSON output (useful in scripts):

```bash
$ python -m cleveragents session create --actor openai/gpt-4o --format json
```

**Actual Output:**
```json
{
  "session_id": "01HXYZ4M1Q3F0R0E5HR8K5T8A",
  "actor": "openai/gpt-4o",
  "namespace": "local",
  "messages": 0,
  "created": "2026-04-07T09:16:42.123456",
  "updated": "2026-04-07T09:16:42.123456"
}
```

---

### Step 4: List All Sessions

After creating a few sessions, list them all:

```bash
$ python -m cleveragents session list
```

**Actual Output:**
```
                                        Sessions
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓

│ Most Recent:    01HXYZ4M                                                                          │

│ Total Messages: 3                                                                                 │
│ Storage:        0 KB                                                                              │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯

✓ OK 2 sessions listed
```

**What's Happening:**
The list command renders a Rich table with five columns: truncated ID (first
8 characters for readability), optional name, bound actor, message count, and
last update time. The **Summary** panel below shows aggregate statistics
including total sessions, most recent, oldest, total message count, and
storage used.

For machine-readable output:

```bash
$ python -m cleveragents session list --format json
```

**Actual Output:**
```json
{
  "sessions": [
    {
      "id": "01HXYZ4M1Q3F0R0E5HR8K5T8A",
      "name": null,
      "actor": "openai/gpt-4o",
      "messages": 3,
      "updated": "2026-04-07T09:22:15.654321"
    },
    {
      "id": "01HXYZ3K9P2E9Q9D4GQ7J4S7Z",
      "name": null,
      "actor": "(none)",
      "messages": 0,
      "updated": "2026-04-07T09:15:33.123456"
    }
  ],
  "summary": {
    "total": 2,
    "most_recent": "01HXYZ4M",
    "oldest": "01HXYZ3K",
    "total_messages": 3,
    "storage": "0 KB"
  }
}
```

---

### Step 5: Send Messages to a Session

Use `session tell` to append a user message and receive an assistant response:

```bash
$ python -m cleveragents session tell \
    --session 01HXYZ4M1Q3F0R0E5HR8K5T8A \
    "What is the capital of France?"
```

**Actual Output:**
```
user: What is the capital of France?
assistant: Acknowledged: What is the capital of France?
```

Send a follow-up message to build conversation history:

```bash
$ python -m cleveragents session tell \
    --session 01HXYZ4M1Q3F0R0E5HR8K5T8A \
    "Now explain the Eiffel Tower's history in one sentence."
```

**Actual Output:**
```
user: Now explain the Eiffel Tower's history in one sentence.
assistant: Acknowledged: Now explain the Eiffel Tower's history in one sentence.
```

You can also override the actor for a single message:

```bash
$ python -m cleveragents session tell \
    --session 01HXYZ4M1Q3F0R0E5HR8K5T8A \
    --actor anthropic/claude-sonnet-4-20250514 \
    "Summarize our conversation so far."
```

**Actual Output:**
```
user: Summarize our conversation so far.
assistant: [anthropic/claude-sonnet-4-20250514] Acknowledged: Summarize our conversation so far.
```

**What's Happening:**
`session tell` appends a `user` message to the session, then generates an
`assistant` response. The `--actor` override routes this specific message
through a different actor without changing the session's default binding.
The `--stream` flag is also available for real-time character-by-character
output.

---

### Step 6: Inspect a Session's Full Details

View the complete session state including recent messages, linked plans,
and token usage:

```bash
$ python -m cleveragents session show 01HXYZ4M1Q3F0R0E5HR8K5T8A
```

**Actual Output:**
```

For JSON output (useful for scripting):

```bash
$ python -m cleveragents session show 01HXYZ4M1Q3F0R0E5HR8K5T8A --format json
```

**Actual Output:**
```json
{
  "session_summary": {
    "id": "01HXYZ4M1Q3F0R0E5HR8K5T8A",
    "actor": "openai/gpt-4o",
    "messages": 6,
    "created": "2026-04-07T09:16:42.123456",
    "updated": "2026-04-07T09:24:18.987654"
  },
  "recent_messages": [
    {"role": "user", "text": "What is the capital of France?"},
    {"role": "assistant", "text": "Acknowledged: What is the capital of France?"},
    {"role": "user", "text": "Now explain the Eiffel Tower's history in one sentence."},
    {"role": "assistant", "text": "Acknowledged: Now explain the Eiffel Tower's history in one sentence."},
    {"role": "user", "text": "Summarize our conversation so far."},
    {"role": "assistant", "text": "[anthropic/claude-sonnet-4-20250514] Acknowledged: Summarize our conversation so far."}
  ],
  "token_usage": {
    "input_tokens": 0,
    "output_tokens": 0,
    "estimated_cost": "$0.0000"
  }
}
```

**What's Happening:**
`session show` renders three panels:
1. **Session Summary** — ID, actor, message count, creation/update timestamps, automation profile
2. **Recent Messages** — last 5 messages (role + truncated content)
3. **Token Usage** — accumulated input/output tokens and estimated cost

If the session has linked plans, a **Linked Plans** table is also shown with
Plan ID, Phase, and State columns. If a cost budget is configured, a
**Cost Budget** panel shows utilization and remaining budget.

### Step 7: Export a Session to JSON

Export the full session data to a portable JSON file:

```bash
$ python -m cleveragents session export \
    --output /tmp/my-session-backup.json \
    01HXYZ4M1Q3F0R0E5HR8K5T8A
```

**Actual Output:**

```

The exported JSON file contains the full session with all messages and a
SHA-256 checksum for integrity verification:

```json
{
  "schema_version": "1.0",
  "session_id": "01HXYZ4M1Q3F0R0E5HR8K5T8A",
  "actor_name": "openai/gpt-4o",
  "namespace": "local",
  "messages": [
    {
      "message_id": "01HXYZ5N2R4G1S1F6IS9L6U9B",
      "role": "user",
      "content": "What is the capital of France?",
      "sequence": 0,
      "timestamp": "2026-04-07T09:22:10.111111",

}
```

**What's Happening:**
The export command:
1. Loads the full session with all messages from the database
2. Serializes to JSON with a stable field order
3. Computes a SHA-256 checksum over the canonical JSON (for import validation)
4. Writes to the output file (or stdout if `--output` is omitted)
5. Renders three Rich panels: **Session Export** (metadata), **Contents**
   (message/plan/metadata counts, schema version), and **Integrity** (checksum)

> **Tip:** Use `--force` to overwrite an existing file without error.

### Step 8: Export a Session as Markdown Transcript

For human-readable sharing (e.g. documentation, code reviews), export as
Markdown:

```bash
$ python -m cleveragents session export \
    --format md \
    --output /tmp/my-session-transcript.md \
    01HXYZ4M1Q3F0R0E5HR8K5T8A
```

**Actual Output (panels):**
```
╭──────────────────────────────────────────── Session Export ──────────────────────────────────────╮

> JSON format for backups you intend to restore.

### Step 9: Import a Session from a JSON Backup

Restore a previously exported session:

```bash
$ python -m cleveragents session import --input /tmp/my-session-backup.json
```

**Actual Output:**
```
╭──────────────────────────────────────────── Session Import ──────────────────────────────────────╮
│ Input:      /tmp/my-session-backup.json                                                          │

│ Schema:     1.0                                                                                  │

│ Schema:    compatible                                                                            │
│ Actor Ref: resolved                                                                              │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯

╭──────────────────────────────────────────── Merge ───────────────────────────────────────────────╮

│ Strategy: create new                                                                             │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯

✓ OK Import completed
```

**What's Happening:**
The import command:
1. Reads and parses the JSON file
2. Validates the checksum against the session data
3. Checks schema version compatibility
4. Resolves the actor reference (if any)
5. Creates a new session in the database with a fresh ULID
6. Renders three panels: **Session Import** (input file, new ID, message count,
   schema version), **Validation** (checksum, schema, actor ref status), and
   **Merge** (whether an existing session was found and the merge strategy)

> **Note:** Import always creates a **new** session with a fresh ULID —
> it does not overwrite the original session if it still exists.

---

### Step 10: Delete a Session

Delete a session permanently with the impact summary:

```bash
$ python -m cleveragents session delete --yes 01HXYZ3K9P2E9Q9D4GQ7J4S7Z
```

**Actual Output:**
```
╭──────────────────────────────────────────── Deletion Summary ────────────────────────────────────╮

│ Plans Orphaned: 0                                                                                │

│ Logs:         preserved                                                                          │

│ Checkpoints:  none                                                                               │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯

✓ OK Session deleted
```

**What's Happening:**
The delete command:
1. Verifies the session exists and captures its message count
2. Shows a confirmation prompt (skipped with `--yes`)
3. Deletes the session from the database
4. Renders a **Deletion Summary** panel (messages removed, storage freed,
   orphaned plans) and a **Cleanup** panel (backups, logs, context, checkpoints)

> **Safety tip:** Always export a session before deleting it if you might
> need the conversation history later.

## Scripting Examples

### Get the Most Recent Session ID

```bash
python -m cleveragents session list --format json | python3 -c "
import sys, json
data = json.load(sys.stdin)
sessions = data.get('sessions', [])
if sessions:
    # Sessions are ordered by updated_at descending
    print(sessions[0]['id'])
else:
    print('No sessions found')
"
```

### Count Sessions by Actor

```bash
python -m cleveragents session list --format json | python3 -c "
import sys, json
from collections import Counter
data = json.load(sys.stdin)
actors = Counter(s['actor'] for s in data.get('sessions', []))
for actor, count in actors.most_common():
    print(f'{count:3d}  {actor}')
"
```

### Backup All Sessions to Individual Files

```bash
python -m cleveragents session list --format json | python3 -c "
import sys, json, subprocess
data = json.load(sys.stdin)
for session in data.get('sessions', []):
    sid = session['id']
    outfile = f'/tmp/session-backup-{sid}.json'
    subprocess.run([
        'python', '-m', 'cleveragents', 'session', 'export',
        '--output', outfile, sid
    ])
    print(f'Backed up {sid} -> {outfile}')
"
```

### Check if a Session Has Messages

```bash
SESSION_ID="01HXYZ4M1Q3F0R0E5HR8K5T8A"
python -m cleveragents session show "$SESSION_ID" --format json | python3 -c "
import sys, json
data = json.load(sys.stdin)
count = data['session_summary']['messages']
print(f'Session has {count} messages')
if count == 0:
    sys.exit(1)
"
```

### Create a Session and Immediately Send a Message

```bash
# Create session and capture the ID
SESSION_ID=$(python -m cleveragents session create --actor openai/gpt-4o --format json \
    | python3 -c "import sys, json; print(json.load(sys.stdin)['session_id'])")

echo "Created session: $SESSION_ID"

# Send a message
python -m cleveragents session tell \
    --session "$SESSION_ID" \
    "Hello! Please introduce yourself."
```

## Session Export Format Reference

The JSON export format (schema version `1.0`) contains:

| Field | Type | Description |
|-------|------|-------------|
| `schema_version` | string | Always `"1.0"` — used for import compatibility checks |
| `session_id` | string | ULID of the original session |
| `actor_name` | string\|null | Bound actor (`namespace/name`) or null |
| `namespace` | string | Session namespace (default: `"local"`) |
| `messages` | array | Full message history (role, content, sequence, timestamp) |
| `linked_plan_ids` | array | ULIDs of plans linked to this session |
| `token_usage` | object | `input_tokens`, `output_tokens`, `estimated_cost` |
| `metadata` | object | Arbitrary session metadata |
| `created_at` | string | ISO 8601 creation timestamp |
| `updated_at` | string | ISO 8601 last-update timestamp |
| `checksum` | string | SHA-256 of the canonical JSON (for integrity verification) |

## Key Takeaways

- **Sessions are ULID-identified** — the 26-character ULID is time-ordered,
  so sessions are naturally sortable by creation time. Use the first 8
  characters as a short reference in the list view.
- **`session create --actor <name>`** binds the session to a specific actor.
  Actor names follow the `<provider>/<model>` convention for built-ins
  (e.g. `openai/gpt-4o`) or `local/<id>` for custom actors.
- **`session list`** shows a Rich table with a Summary panel. Use
  `--format json` to get structured data for scripting.
- **`session show <id>`** renders Session Summary, Recent Messages (last 5),
  Linked Plans, and Token Usage panels. Use `--format json` for the full
  `as_cli_dict()` output.
- **`session tell --session <id> "<prompt>"`** appends a user message and
  generates an assistant response. Use `--actor` to override the actor for
  a single message; use `--stream` for real-time output.
- **`session export --output <file> <id>`** writes a JSON backup with a
  SHA-256 checksum. Use `--format md` for a human-readable Markdown
  transcript (lossy — cannot be re-imported).
- **`session import --input <file>`** restores a session from a JSON backup,
  always creating a new session with a fresh ULID.
- **`session delete --yes <id>`** shows a Deletion Summary and Cleanup panel
  before removing the session. Export first if you need the history.

## Try It Yourself

- **Create a session and immediately send a message in one pipeline:**
  ```bash
  SID=$(python -m cleveragents session create --format json | python3 -c "import sys,json; print(json.load(sys.stdin)['session_id'])")
  python -m cleveragents session tell --session "$SID" "Hello!"
  ```
- **Export all sessions to a backup directory:**
  ```bash
  mkdir -p ~/session-backups
  python -m cleveragents session list --format json | python3 -c "
  import sys, json, subprocess
  for s in json.load(sys.stdin)['sessions']:
      subprocess.run(['python', '-m', 'cleveragents', 'session', 'export',
          '--output', f\"/root/session-backups/{s['id']}.json\", s['id']])
  "
  ```
- **Stream a response in real-time:**
  ```bash
  python -m cleveragents session tell --session <ID> --stream "Tell me a story."
  ```
- **Inspect token usage across all sessions:**
  ```bash
  python -m cleveragents session list --format json | python3 -c "
  import sys, json
  data = json.load(sys.stdin)
  print(f\"Total sessions: {data['summary']['total']}\")
  print(f\"Total messages: {data['summary']['total_messages']}\")
  "
  ```
