Bug Report

Summary

agents session list --format table and agents session list --format plain produce malformed output. The table format renders raw JSON strings inside table cells (because the sessions list is serialized as a JSON blob per cell), and the plain format renders raw JSON inline for each list item.

Spec Reference

docs/specification.md lines 1611–1649 (session list table/plain output):

Expected table output:

Sessions
ID        Name             Actor               Messages  Updated
--------  ---------------  ------------------  --------  ----------------
01HXM2A6  weekly-planning  local/orchestrator  6         2026-02-08 12:44
01HXM1F2  refactor-sprint  local/orchestrator  14        2026-02-07 18:11

Expected plain output:

sessions:
  - id: 01HXM2A6
    name: weekly-planning
    ...

Actual Behavior

--format table:

┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃ sessions                                                                                          ┃ summary                                                                                          ┃
┡━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┩
│ [{"id": "01KNQA60...", "name": null, "actor": "(none)", "messages": 0, ...}]                      │ {"total": 3, "most_recent": "01KNT0G0", ...}                                                     │
└───────────────────────────────────────────────────────────────────────────────────────────────────┴──────────────────────────────────────────────────────────────────────────────────────────────────┘

The table has only 2 columns (sessions and summary) with the entire sessions list as a JSON blob in one cell.

--format plain:

sessions:
  - {"id": "01KNQA60VSA6QACSWZM0P4DYH9", "name": null, "actor": "(none)", "messages": 0, "updated": "2026-04-08T19:47:50.265807"}
  - {"id": "01KNT0FE...", ...}
summary:
  total: 4
  most_recent: 01KNT0N7
  ...

Each session is rendered as a raw JSON blob instead of indented key-value pairs.

Root Cause

src/cleveragents/cli/formatting.py lines 117–149 (_format_table): The function receives the top-level dict {"sessions": [...], "summary": {...}} and treats each top-level key as a column. Since sessions is a list, it gets JSON-serialized into a single cell.

src/cleveragents/cli/formatting.py lines 105–111 (_format_plain_dict): When a list item is a dict, it is serialized with json.dumps() instead of being rendered as indented key-value pairs.

The table format for session list should iterate over the sessions list and render each session as a row. The plain format should render each session dict as indented key-value pairs.

Steps to Reproduce

agents session create
agents session list --format table
agents session list --format plain

Code Location

src/cleveragents/cli/formatting.py lines 117–149 (_format_table)
src/cleveragents/cli/formatting.py lines 96–114 (_format_plain_dict)
src/cleveragents/cli/commands/session.py lines 303–304 (list_sessions command)

Severity

High — The --format table output is completely unusable for human reading. The --format plain output is also broken for list items. Both are core output formats required by the spec.
