Bug Report

Feature area: Output rendering framework / format resolution
Severity: Medium
Discovered by: UAT Testing (uat-tester-cli-rendering-001)

Expected Behavior (from ADR-021)

ADR-021 specifies the format resolution chain:

The format is resolved per-invocation: --format CLI flag > CLEVERAGENTS_FORMAT env var > core.format config key > default (rich).

Setting CLEVERAGENTS_FORMAT=json should make all CLI commands output JSON by default, without needing to pass --format json every time.

Expected usage:

export CLEVERAGENTS_FORMAT=json
agents version          # Should output JSON
agents info             # Should output JSON
agents config list      # Should output JSON

Actual Behavior

The main_callback in src/cleveragents/cli/main.py uses OutputFormat.RICH as the hardcoded default without checking CLEVERAGENTS_FORMAT:

# src/cleveragents/cli/main.py lines 310-320
fmt: Annotated[
    OutputFormat,
    typer.Option(
        "--format",
        "-f",
        help="Output format for all subcommands: ...",
    ),
] = OutputFormat.RICH,  # Hardcoded default — CLEVERAGENTS_FORMAT not checked!

The Settings class in config/settings.py does define format reading from CLEVERAGENTS_FORMAT (line 136-143), but this value is never used to set the default in main_callback.

This is documented as a known deviation in src/cleveragents/cli/output/__init__.py:

SD-15 (CLEVERAGENTS_FORMAT env var not checked)
The spec defines CLEVERAGENTS_FORMAT for overriding the default format. This implementation only accepts --format CLI flag.

Steps to Reproduce

export CLEVERAGENTS_FORMAT=json
agents version
# Outputs Rich-formatted text instead of JSON

Code Location

src/cleveragents/cli/main.py — main_callback function (lines 310–320)
src/cleveragents/config/settings.py — format field (lines 136–143)
src/cleveragents/cli/output/__init__.py — SD-15 deviation note (lines 79–81)

Fix Required

Read CLEVERAGENTS_FORMAT (or settings.format) in main_callback to set the default format:

import os

@app.callback()
def main_callback(
    ctx: typer.Context,
    ...
    fmt: Annotated[
        OutputFormat,
        typer.Option("--format", "-f", help="..."),
    ] = OutputFormat.RICH,
) -> None:
    # Resolve format: CLI flag > CLEVERAGENTS_FORMAT env var > core.format config > rich
    effective_fmt = fmt
    if fmt == OutputFormat.RICH:  # Only override if user didn't explicitly set --format
        env_format = os.environ.get("CLEVERAGENTS_FORMAT", "").lower()
        if env_format in {f.value for f in OutputFormat}:
            effective_fmt = OutputFormat(env_format)
    
    ctx.ensure_object(dict)
    ctx.obj["format"] = effective_fmt.value
