Output Formats

JSON, CSV, text, and other output format options for CLEO commands

Output Formats

CLEO commands support multiple output formats for different use cases. This reference covers format options and usage patterns.

Format Auto-Detection

CLEO automatically detects the appropriate output format:

Context	Default Format
Interactive terminal (TTY)	Text (human-readable)
Piped output (non-TTY)	JSON
Explicit --format flag	Specified format

# Terminal: text output
cleo list

# Piped: JSON output
cleo list | jq '.tasks[]'

# Explicit format
cleo list --format json
cleo list --format text

Available Formats

  },
  "summary": {

- [ ] **T001**: Implement auth (high)
- [ ] **T002**: Fix login bug (critical)
- [x] **T003**: Set up CI (done)

JSON Envelope Structure

All JSON output follows a consistent envelope:

{
  "_meta": {
    "command": "command-name",
    "timestamp": "ISO-8601",
    "version": "0.54.0"
  },
  "summary": {
    // Command-specific summary
  },
  "data": {
    // Main payload (or "tasks", "task", etc.)
  },
  "error": {
    // Present only on error
    "code": "E_NOT_FOUND",
    "message": "Task T999 not found",
    "fix": "cleo list --status pending"
  }
}

Color Control

Disable Colors

# Standard NO_COLOR environment variable
NO_COLOR=1 cleo list

# Also works
CLEO_NO_COLOR=1 cleo list

Force Colors

# Force colors even in piped output
FORCE_COLOR=1 cleo list | less -R

Command-Specific Formats

list command

Format	Description
text	Full task details with colors
json	Complete task objects
compact	One-line per task
markdown	Checklist format
table	ASCII table

analyze command

Default: JSON (designed for LLM agents)

Format	Description
json	Structured analysis with scores
human	Text summary with recommendations

export command

Format	Description
csv	Comma-separated values
tsv	Tab-separated values
json	Full JSON export
jsonl	JSON Lines (one per line)

dash command

Format	Description
text	ASCII dashboard
json	Structured metrics
compact	Single-line summary

LLM Agent Best Practices

Use JSON for Parsing

Always use --json when processing output programmatically

Prefer Native Filters

Use --status, --label, --phase instead of | jq 'select(...)'

Check success Field

Always verify "success": true in JSON responses

Use find for Discovery

cleo find returns minimal output (99% less than list)
