Metadata

Branch: fix/format-output-rich-color-renderers
Commit Message: fix(cli): fix format_output() to use rich and color renderers instead of JSON fallback
Milestone: v3.7.0
Parent Epic: #936

Background

The format_output() function in src/cleveragents/cli/formatting.py contains a routing bug where the rich and color output formats are not dispatched to their correct renderers. The rich format silently falls through all explicit format checks and returns JSON output via the final fallback. The color format is incorrectly routed to the plain-text renderer instead of a color-aware renderer.

Per ADR-021 and the project specification, rich is the default CLI output format and must produce fully styled terminal output using Rich library components (Panel, Table, Tree, Syntax, Progress/Spinner, Markdown). This bug means that any command using the legacy format_output() function — including version, info, and diagnostics — produces JSON when --format rich is requested, which is the default.

Current Behavior

In src/cleveragents/cli/formatting.py, the format_output() function (lines ~130–145):

if fmt == OutputFormat.TABLE.value:
    return _format_table(safe_data)
if fmt == OutputFormat.COLOR.value:
    return _format_plain(safe_data)  # BUG: color uses plain renderer
# `rich` and any unknown value fall back to JSON
return _format_json(safe_data)  # BUG: rich falls back to JSON

Reproduction:

from cleveragents.cli.formatting import format_output

data = {"name": "test", "status": "active"}

result = format_output(data, "rich")
# Expected: Rich-styled terminal output (panels, colors, etc.)
# Actual:   '{\n  "name": "test",\n  "status": "active"\n}'

result = format_output(data, "color")
# Expected: ANSI-colored terminal output
# Actual:   "name: test\nstatus: active"

Expected Behavior

format_output(data, "rich") must produce fully styled terminal output using Rich library components (Panel, Table, Tree, Syntax highlighting) as specified in ADR-021.
format_output(data, "color") must produce ANSI-colored terminal output, not plain text.
The newer format_output_session() correctly delegates to the appropriate materializer; format_output() must be brought into alignment.

Impact

Severity: High — rich is the default format; commands using format_output() (version, info, diagnostics) produce JSON by default instead of styled output.
The color format produces plain text, defeating its purpose.
Users requesting --format rich receive JSON, which is confusing and violates the spec contract.

Subtasks

Audit format_output() in src/cleveragents/cli/formatting.py to identify all missing/incorrect format dispatch branches
Implement _format_rich() renderer (or wire to existing Rich materializer) for the rich format branch
Implement _format_color() renderer (ANSI-colored output) for the color format branch
Add explicit dispatch for OutputFormat.RICH in format_output() routing logic
Fix OutputFormat.COLOR dispatch to use _format_color() instead of _format_plain()
Verify format_output() and format_output_session() are consistent in their format routing
Tests (unit): Add/update unit tests for format_output() covering rich and color format paths
Tests (Behave): Add BDD scenarios for --format rich and --format color on affected commands (version, info, diagnostics)
Tests (Robot): Add integration tests confirming styled output is produced end-to-end
Verify coverage >= 97% via nox -s coverage_report
Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
format_output(data, "rich") produces Rich-library styled terminal output (not JSON) for all affected commands.
format_output(data, "color") produces ANSI-colored output (not plain text).
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
All nox stages pass.
Coverage >= 97%.

Starting implementation on branch fix/format-output-rich-color-renderers.

Analysis:

Bug confirmed: format_output() in src/cleveragents/cli/formatting.py has two routing bugs:
1. rich format falls through all checks and returns JSON via final fallback
2. color format incorrectly routes to _format_plain() instead of a color-aware renderer
format_output_session() already correctly uses RichMaterializer and ColorMaterializer
Fix: Add _format_rich() and _format_color() functions that delegate to format_output_session(), then wire them into format_output() routing

TDD approach: Writing failing tests first, then implementing the fix.

PR #3227 Review: Changes Requested

PR #3227 has been reviewed. The bug fix approach is correct (routing rich → RichMaterializer and color → ColorMaterializer via OutputSession), but four blocking issues were identified:

CI lint failure — the lint check is failing
Redundant lazy imports — OutputSession is imported at the top of formatting.py but also re-imported inside the two new functions
Steps file exceeds 500 lines — cli_output_formats_steps.py is 546 lines (limit: 500); new steps should be extracted to a separate file
Extra blank lines in robot/helper_cli_formats.py (3 instead of 2 between functions)

The issue worker should address these and push a fix.
