name: render-output description: Renders structured data to terminal with optimal formatting. Use when presenting agent results, displaying data to users, formatting command output, or showing validation reports. Transforms raw data into clear, scannable terminal output.

Key principle: Output should be scannable in under 5 seconds. Choose the simplest pattern that communicates the information effectively.

<quick_start> Select pattern based on data type:

Data TypePatternUse When
Machine-readableTOON blockReturning data to subagents
ListingsMarkdown tableHuman comparisons, listings
Action resultStatus lineSingle operation outcome
ValidationBox reportMulti-check with pass/fail
CountsSummary lineAggregates, distributions

Default to the simplest pattern. Escalate complexity only when needed. </quick_start>

@type: [SchemaType]
@id: [unique-identifier]
[scalar properties]

[table]{columns|tab}:
[row1 tab-separated]
[row2 tab-separated]

Rules:

  • ALWAYS include @type and @id
  • Use tab-separated tables for arrays
  • Prefer flat structure (avoid nesting >2 levels)
  • No prose - data only
  • Use toon language tag for syntax highlighting

Example:

@type: AssessAction
@id: 005-auth
actionStatus: CompletedActionStatus

validationStatus: VALID
checksPerformed: 10
issues.critical: 0
issues.warning: 1

</toon_pattern>

<table_pattern> For human-readable listings and comparisons:

| Column1 | Column2 | Column3 |
|---------|---------|---------|
| value1  | value2  | value3  |

Rules:

  • Maximum 6 columns (truncate or split if more)
  • Align columns consistently
  • Truncate cells >30 chars with ...
  • Right-align numbers
  • Keep header row concise

Example:

| ID         | Name           | Stage       | Priority |
|------------|----------------|-------------|----------|
| 005-auth   | Implement Auth | in-progress | P1       |
| 006-mgmt   | User Management| ready       | P2       |

</table_pattern>

<status_pattern> For single action outcomes:

[symbol] [action verb] [target]: [brief result]

Symbols:

  • success
  • failure
  • warning
  • transition

Examples:

✓ Created outcome 005-auth in queued/
✓ Synced capabilities-info.toon (12 capabilities)
✗ Validation failed: 3 critical issues
⚠ Index stale, auto-syncing...

For short lists (<5 items), use indented bullets:

✓ Created 3 outcomes
  - 005-auth (queued)
  - 006-mgmt (queued)
  - 007-report (queued)

</status_pattern>

<box_pattern> For validation reports and multi-section results:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[Title]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Section1:     [✓/✗] [details]
Section2:     [✓/✗] [details]
Section3:     [✓/✗] [details]

Overall: [PASS ✓ / FAIL ✗ / NEEDS_ATTENTION ⚠]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Use box drawing characters:

  • horizontal line
  • vertical line (if needed)
  • ┌┐└┘ corners (if needed)

Reserve for:

  • Validation reports (>3 checks)
  • Multi-section summaries
  • Error reports with details </box_pattern>

<summary_pattern> For counts, distributions, and quick stats:

Single line for simple counts:

Summary: 11 total | 3 queued | 2 ready | 1 in-progress | 5 completed

Two lines for distributions:

Summary: 11 total | 3 queued | 2 ready | 1 in-progress | 5 completed
         9 parent | 2 child | P1: 6 | P2: 4 | P3: 1

Rules:

  • Use | as separator
  • Align related groups
  • Maximum two lines </summary_pattern>

<distribution_pattern> For visual distribution of values:

Maturity Distribution:
  0-29%:   ### (3)
  30-59%:  ##### (5)
  60-79%:  ### (3)
  80-100%: # (1)

Rules:

  • Use # for bar chart
  • Include count in parentheses
  • Align labels and bars </distribution_pattern>

<pattern_selection> Choose pattern based on:

  1. Audience: Subagent (TOON) vs Human (table/status/box)
  2. Complexity: Simple (status) → Complex (box)
  3. Data shape: List (table) vs Result (status) vs Validation (box)

Decision tree:

Is output for another agent?
├─ Yes → TOON block
└─ No → Is it a single action result?
        ├─ Yes → Status line
        └─ No → Is it validation with pass/fail?
                ├─ Yes → Box report
                └─ No → Is it a list/comparison?
                        ├─ Yes → Markdown table
                        └─ No → Summary line

</pattern_selection>

DO NOT use emoji. Stick to these standard symbols.

<anti_patterns> Avoid these common mistakes:

  • Excessive whitespace: Don't add blank lines between every element
  • Nested boxes: Don't put boxes inside boxes
  • Mixed styles: Don't combine table + box in same output
  • Emoji overuse: Stick to standard symbols (✓✗⚠)
  • Long prose: Output should be data-focused, not explanatory
  • Missing language tags: Always tag code blocks (toon, markdown)
  • Inconsistent alignment: Align columns and values consistently
  • Over-engineering: Don't use box for simple status
  • Column overflow: Keep tables under 6 columns </anti_patterns>

<success_criteria> Output meets quality standards when:

  • Pattern matches data type (use decision tree)
  • Symbols used consistently throughout
  • No excessive whitespace or blank lines
  • Code blocks have language tags
  • Tables stay under 6 columns
  • Box reports used only for complex validation
  • TOON used for machine-readable returns
  • Human output is scannable in <5 seconds
  • No mixed patterns in single output </success_criteria>
