--quiet flag does not suppress output (coverage check test)

[Serhan-Asad]

Description

Running pdd --quiet generate prompts/greet_python.prompt still displays:

• INFO log lines (pdd.llm_invoke - INFO - ...)
• Rich panels ("Starting prompt preprocessing", "Preprocessing complete")
• "Doubling curly brackets..." messages
• WARNING log lines (cloud fallback warnings)
• "Successfully loaded prompt: ..." messages

Expected Behavior

--quiet should suppress all non-essential output. Only errors and the final result should be shown.

Steps to Reproduce

pdd --quiet generate prompts/greet_python.prompt

Actual Output

Full verbose-style output including INFO logs, Rich panels, and warnings despite --quiet flag.

Environment

• pdd-cli v0.0.144
• macOS

Step 1: Duplicate Check

Status: Duplicate of #90 (original unresolved — proceeding with investigation)

Search Performed

• Searched for: "quiet flag", "suppress output", "verbose logging"
• Issues reviewed: 8 (--quiet flag does not suppress output #90, Bug: INFO log messages printed on every command, even with --quiet #115, --quiet flag does not suppress output #122, --quiet flag does not suppress output during generate #131, --quiet flag does not suppress non-essential output #132, --quiet flag does not suppress output #160, --quiet flag does not suppress output (test comparison) #165, --quiet flag does not suppress output (anti-pattern test) #166)

Findings

Issue #168 has the exact same description (verbatim) as the following issues, all reporting that pdd --quiet generate still shows INFO logs, Rich panels, warnings, and success messages:

Issue	State	Notes
#90	OPEN	Canonical/earliest. No comments, no fix merged.
#122	OPEN	Same bug, slightly expanded description. Unresolved.
#131	CLOSED	Closed as duplicate of #90.
#132	CLOSED	Fix attempted (tests passed locally), but no PR was merged upstream.
#160	OPEN	Draft PR promptdriven#534 created with failing tests. Not merged.
#165	OPEN	Same bug, "(test comparison)" variant.
#166	OPEN	Same bug, "(anti-pattern test)" variant.

The canonical issue is #90. However, #90 remains unresolved — no fix has been merged. Issue #132's fix was applied and tests passed, but the changes were never merged to the main branch. PR promptdriven#534 (from #160) is still in draft with failing tests.

Per workflow rules: since the original issue is unresolved, this issue will proceed with investigation rather than being closed.

Proceeding to Step 2: Documentation Check

[Serhan-Asad]

Step 2: Documentation Check

Status: Confirmed Bug

Documentation Reviewed

• pdd --help CLI help text (pdd/core/cli.py lines 244-249)
• README.md — no mention of --quiet flag behavior
• CLAUDE.md — no mention of --quiet flag
• CONTRIBUTING.md — not present
• pdd/core/cli.py — flag definition and usage
• pdd/preprocess.py — output during preprocessing
• pdd/load_prompt_template.py — output during template loading
• pdd/code_generator_main.py — output during code generation
• pdd/agentic_architecture.py — output during architecture steps
• tests/core/test_cli.py — existing quiet flag tests

Findings

The --quiet flag is defined and documented in the CLI help text:

--quiet — Decrease output verbosity for minimal information.

The flag is properly stored in ctx.obj["quiet"] and correctly overrides --verbose. However, the flag is inconsistently respected across the codebase:

Modules that DO check quiet before printing:

• pdd/core/cli.py — auto-update messages, result callback summary
• pdd/code_generator_main.py — several output points check not quiet

Modules that IGNORE quiet (root cause):

• pdd/preprocess.py — 30+ console.print() calls unconditionally output Rich panels ("Starting prompt preprocessing", "Preprocessing complete"), "Doubling curly brackets..." messages, file include processing, and more
• pdd/load_prompt_template.py — prints "Successfully loaded prompt: ..." unconditionally via print_formatted()
• pdd/agentic_architecture.py — status/warning messages printed without quiet check
• pdd/agentic_architecture_orchestrator.py — step progress messages printed without quiet check
• Python logging module — INFO and WARNING log levels are not adjusted when --quiet is set

Verdict: The documented behavior ("Decrease output verbosity for minimal information") clearly states that --quiet should reduce output, but the majority of output-producing modules ignore the flag entirely. This is a confirmed bug — the code does not match its documented behavior.

Step 3: Triage

Status: Proceed

Summary

We have all the information needed to reproduce and fix this issue:

• Expected behavior: --quiet should suppress all non-essential output (INFO logs, Rich panels, warnings). Only errors and the final result should be shown.
• Actual behavior: Full verbose-style output including INFO logs, Rich panels ("Starting prompt preprocessing", "Preprocessing complete"), "Doubling curly brackets..." messages, and WARNING log lines appear despite --quiet.
• Reproduction steps: Clear and simple — pdd --quiet generate prompts/greet_python.prompt.
• Code area identified: The --quiet flag is properly defined and propagated in pdd/core/cli.py (stored in ctx.obj["quiet"]), and cli.py itself checks it before printing. However, downstream modules like pdd/preprocess.py contain numerous unconditional console.print() calls (Panels, status messages, debug info) that never check the quiet flag. This is the root cause — output-producing modules bypass the quiet check.

This is a well-documented, frequently reported issue (7 duplicates) with a clear reproduction path and identified code areas.

Proceeding to Step 4: Reproduction

[Serhan-Asad]

Step 4: Reproduction

Status: Reproduced

Environment

• pdd-cli v0.0.157 (editable install from gltanaka/pdd)
• Python 3.12.7
• macOS Darwin 24.3.0 (arm64)

Steps Taken

1. Verified --quiet flag is defined in cli.py:244-249 and stored in ctx.obj["quiet"] at line 333
2. Traced the generate command flow: commands/generate.py → code_generator_main() → preprocess() / load_prompt_template()
3. Inspected function signatures of downstream modules for quiet parameter support
4. Intercepted console.print calls from preprocess() to capture actual output
5. Verified logging configuration is independent of the --quiet flag

Observed Behavior

Automated reproduction confirmed all 5 bug vectors:

=== Test 1: preprocess.py has no quiet parameter ===
preprocess() parameters: ['prompt', 'recursive', 'double_curly_brackets', 'exclude_keys', '_seen']
Has quiet parameter: False
RESULT: BUG CONFIRMED

=== Test 2: load_prompt_template.py has no quiet parameter ===
load_prompt_template() parameters: ['prompt_name']
Has quiet parameter: False
RESULT: BUG CONFIRMED

=== Test 3: preprocess() prints output when called ===
Number of console.print calls in preprocess(): 5
Number of "if not quiet" guards: 0
RESULT: BUG CONFIRMED

=== Test 4: double_curly() prints unconditionally ===
double_curly has console.print: True
double_curly checks quiet: False
RESULT: BUG CONFIRMED

=== Test 5: load_prompt_template prints on success ===
Has "Successfully loaded prompt" message: True
Checks quiet: False
RESULT: BUG CONFIRMED

Captured actual output from preprocess() — these print with NO way to suppress:

Total console.print calls captured: 3
  [1] Panel("Starting prompt preprocessing")
  [2] "Doubling curly brackets..."
  [3] Panel("Preprocessing complete")

Logging level is uncontrolled:

Logger level: 0 (NOTSET)
The CLI --quiet flag does not adjust the logging level.
INFO-level log messages will appear regardless of --quiet.

Affected Files

• pdd/preprocess.py:113 - preprocess() has NO quiet parameter; 5 unconditional console.print() calls (lines 116, 123, 142, 457, plus conditional ones in sub-functions)
• pdd/preprocess.py:453 - double_curly() unconditionally prints "Doubling curly brackets..."
• pdd/load_prompt_template.py:50 - Unconditionally prints "Successfully loaded prompt: ..." on every load
• pdd/load_prompt_template.py:42-43 - Unconditionally prints error messages via print_formatted()
• pdd/code_generator_main.py:746-906 - Calls pdd_preprocess() 6 times without passing quiet
• pdd/llm_invoke.py - Logger setup (lines 11-109) has no integration with --quiet flag
• pdd/core/cli.py:244-249,333 - Quiet is properly DEFINED here but not propagated downstream

Notes

• The --quiet flag is correctly defined in cli.py and passed to code_generator_main.py (line 284: quiet = cli_params.get('quiet', False))
• code_generator_main.py uses quiet in ~6 guard conditions — but these only cover a fraction of the output
• The core issue is that preprocess() and load_prompt_template() have NO quiet parameter at all, so even though quiet=True in the CLI context, these functions cannot receive or respect it
• The Python logging module operates independently — the --quiet flag never adjusts the log level, so INFO/WARNING messages from llm_invoke.py always appear

---

Proceeding to Step 5: Root Cause Analysis

[Serhan-Asad]

Step 5: Root Cause Analysis

Root Cause Identified: Yes

Summary

The --quiet flag is correctly parsed in cli.py and stored in ctx.obj["quiet"], but it is never propagated to the three output subsystems that produce the unwanted output: (1) preprocess.py's console.print() calls, which lack a quiet parameter entirely, (2) load_prompt_template.py's rich.print() calls, which have no quiet mechanism, and (3) the Python logging module in llm_invoke.py, whose log level is set at module import time (defaulting to INFO) and is never adjusted when --quiet is active. The codebase has ~70 independent Console() instances across different modules, and none of them are told about quiet mode. The core design gap is that cli.py stores quiet in ctx.obj but never uses it to silence the output mechanisms before invoking downstream commands.

Technical Details

Location 1: pdd/preprocess.py:113-142 — No quiet parameter

def preprocess(prompt: str, recursive: bool = False, double_curly_brackets: bool = True, exclude_keys: Optional[List[str]] = None, _seen: Optional[set] = None) -> str:
    # ...
    console.print(Panel("Starting prompt preprocessing", style="bold blue"))  # line 123 — unconditional
    # ...
    prompt = double_curly(prompt, exclude_keys)  # calls double_curly which also prints unconditionally
    # ...
    console.print(Panel("Preprocessing complete", style="bold green"))  # line 142 — unconditional

Location 2: pdd/preprocess.py:457 — double_curly() unconditional print

def double_curly(text: str, exclude_keys: Optional[List[str]] = None) -> str:
    console.print("Doubling curly brackets...")  # line 457 — unconditional

Location 3: pdd/load_prompt_template.py:50 — unconditional print

print_formatted(f"[green]Successfully loaded prompt: {prompt_name}[/green]")  # line 50 — unconditional

Location 4: pdd/llm_invoke.py:12-22 — logging level ignores quiet

logger = logging.getLogger("pdd.llm_invoke")
PDD_LOG_LEVEL = os.getenv("PDD_LOG_LEVEL", "INFO")
if PRODUCTION_MODE:
    logger.setLevel(logging.WARNING)
else:
    logger.setLevel(getattr(logging, PDD_LOG_LEVEL, logging.INFO))  # Always INFO unless env var set

Location 5: pdd/code_generator_main.py:746-906 — 6 calls to pdd_preprocess() without quiet

orig_proc = pdd_preprocess(original_prompt_content_for_incremental, recursive=True, ...)  # line 746
orig_proc = pdd_preprocess(orig_proc, recursive=False, ...)  # line 748
new_proc = pdd_preprocess(prompt_content, recursive=True, ...)  # line 750
new_proc = pdd_preprocess(new_proc, recursive=False, ...)  # line 752
processed_prompt_for_cloud = pdd_preprocess(prompt_content, recursive=True, ...)  # line 783
processed_prompt_for_cloud = pdd_preprocess(processed_prompt_for_cloud, recursive=False, ...)  # line 785
local_prompt = pdd_preprocess(prompt_content, recursive=True, ...)  # line 904
local_prompt = pdd_preprocess(local_prompt, recursive=False, ...)  # line 906

Each call produces 2 Rich panels + 1 "Doubling curly brackets..." = 3 output lines, totaling up to 24 unwanted output lines per generate command.

Why it fails: The --quiet flag reaches cli.py correctly and is stored in ctx.obj["quiet"]. But the downstream output-producing functions use their own module-level Console() instances (not shared) and don't accept a quiet parameter. The Python logging system is configured at import time, never re-configured based on the CLI flag.

External Research

• Search terms: "python click quiet flag rich console", "python rich console quiet mode", "python logging quiet flag cli"
• Sources checked: Rich documentation, Click documentation, Python.org discussion forums, GitHub issues
• Relevant findings: Rich's Console class has a built-in quiet property (console.quiet = True) that suppresses all output from console.print(). This is the recommended approach per Rich docs. The standard pattern for CLI apps is to either (a) use a shared Console singleton and set console.quiet = True centrally, or (b) pass quiet as a parameter through the call chain (the pattern this codebase already uses in some modules).

Repository History

• Relevant commits: a3ab7ec5d (Greg Tanaka, 2025-03-19) — original preprocess() with unconditional console.print() calls. These lines have never been gated by a quiet flag since initial creation.
• Related PRs: PR test: add failing tests for --quiet flag suppression (#166) #167 (fix/issue-166), PR Add failing tests for --quiet flag bug (#132) #133 (fix/issue-132), PR Add failing tests for #486: --quiet flag not suppressing output #94 (fix/issue-486) — all DRAFT, none merged. All attempt to add failing tests for this bug but no production fix has been merged.
• Similar past issues: Issues --quiet flag does not suppress output #90, --quiet flag does not suppress output #122, --quiet flag does not suppress output during generate #131, --quiet flag does not suppress non-essential output #132, --quiet flag does not suppress output #160, --quiet flag does not suppress output (test comparison) #165, --quiet flag does not suppress output (anti-pattern test) #166 — all report the same bug. Issue Bug: --quiet flag suppresses errors (exit code 2 with no output) #89 reports a related but different problem where --quiet suppresses error output too aggressively.

Experiments Performed

1. Verified preprocess() signature lacks quiet parameter — inspect.signature(preprocess) confirms parameters are (prompt, recursive, double_curly_brackets, exclude_keys, _seen) with no quiet.
2. Confirmed Rich Console.quiet suppresses output — Setting console.quiet = True completely silences all console.print() calls. This is a built-in Rich feature.
3. Counted independent Console instances — Found ~70 separate Console() instantiations across the codebase. No shared singleton pattern exists.
4. Verified logging never adjusts for quiet — llm_invoke.py has set_verbose_logging() but no corresponding set_quiet_logging(). The logger defaults to INFO level and is never raised to ERROR when --quiet is active.
5. Confirmed preprocess_main.py shows the gap — This module properly gates its OWN output with if not ctx.obj.get("quiet"): but calls preprocess() at line 90 without passing quiet, because preprocess() doesn't accept it.

Fix Location

• File(s) to modify:

  1. pdd/preprocess.py — Add quiet: bool = False parameter to preprocess() and double_curly(), guard all console.print() calls with if not quiet:
  2. pdd/load_prompt_template.py — Add quiet: bool = False parameter to load_prompt_template(), guard non-error prints
  3. pdd/code_generator_main.py — Pass quiet=quiet to all pdd_preprocess() calls (8 call sites)
  4. pdd/llm_invoke.py — Add quiet mode to set_verbose_logging() (or add set_quiet_logging()) that raises log level to ERROR when quiet is active
  5. pdd/core/cli.py — When --quiet is True, call set_verbose_logging/set_quiet_logging to adjust logging level

• Why this location: The symptoms appear across multiple modules, but the root cause is that these modules lack the mechanism to receive and respect the quiet flag. The cli.py module correctly captures the flag but doesn't propagate it. The fix must both (a) add quiet parameters to the leaf functions and (b) ensure callers pass the flag through.

• Existing pattern: construct_paths.py (line 831), crash_main.py (line 77), fix_verification_main.py (line 177), and many other modules already accept quiet: bool parameters and guard output with if not quiet:. This is the established codebase pattern — over 60 occurrences of if not quiet: guards exist in modules that properly handle the flag.

• Fix approach: Extend the existing quiet parameter pattern:

  1. Add quiet: bool = False to preprocess(), double_curly(), and load_prompt_template() signatures
  2. Wrap all non-error console.print() calls with if not quiet:
  3. Update all callers to pass quiet from ctx.obj or their own quiet parameter
  4. For logging: either add a set_quiet_logging() function in llm_invoke.py that sets level to ERROR, or modify set_verbose_logging() to accept a quiet flag

Proceeding to Step 5.5: Prompt Classification

[Serhan-Asad]

Step 5.5: Prompt Classification

Classification: Prompt Defect

DEFECT_TYPE: prompt
PROMPT_FIXED: pdd/prompts/preprocess_python.prompt
PROMPT_FIXED: pdd/prompts/load_prompt_template_python.prompt

Analysis

The bug is a prompt defect, not a code bug. The code correctly implements what the prompts specify — but the prompts themselves are incomplete. They don't include quiet parameter support, so the generated code has no mechanism to suppress output when --quiet is passed.

Evidence

• Prompt specifies (preprocess_python.prompt): Function signature preprocess(prompt, recursive, double_curly_brackets, exclude_keys) with no quiet parameter. No mention of conditional output suppression.
• Prompt specifies (load_prompt_template_python.prompt): Requirement 3 says "Print success message with prompt name" unconditionally. No quiet parameter in inputs.
• Code implements: Exactly what the prompts say — prints unconditionally via console.print() because the prompts don't specify any quiet behavior.
• User expects: --quiet should suppress all non-essential output (Rich panels, progress messages, success messages). Only errors and final results should appear.

Root Cause Chain

1. cli_python.prompt correctly defines --quiet flag
2. code_generator_main_python.prompt correctly accepts quiet as input
3. But: preprocess_python.prompt has no quiet parameter → code can't receive it
4. But: load_prompt_template_python.prompt has no quiet parameter → code can't receive it
5. But: code_generator_main_python.prompt step 2 calls preprocess() without mentioning quiet propagation

The prompts create a broken contract chain: the CLI captures --quiet but intermediate module prompts don't specify how to propagate it.

Prompt Changes Made

File 1: pdd/prompts/preprocess_python.prompt

Before:

% Function Signature
    def preprocess(prompt: str, recursive: bool = False, double_curly_brackets: bool = True, exclude_keys: Optional[List[str]] = None) -> str

% Inputs/Outputs
    - prompt: The prompt string to preprocess
    - recursive: When True, resolve includes but defer `<shell>` and `<web>` execution
    - double_curly_brackets: When True, escape single curly braces as double braces
    - exclude_keys: Variable names to exclude from brace doubling
    - Returns: The preprocessed prompt (preserve leading/trailing whitespace)

After:

% Function Signature
    def preprocess(prompt: str, recursive: bool = False, double_curly_brackets: bool = True, exclude_keys: Optional[List[str]] = None, quiet: bool = False) -> str

% Inputs/Outputs
    - prompt: The prompt string to preprocess
    - recursive: When True, resolve includes but defer `<shell>` and `<web>` execution
    - double_curly_brackets: When True, escape single curly braces as double braces
    - exclude_keys: Variable names to exclude from brace doubling
    - quiet: When True, suppress all non-error console output (Rich panels, progress messages, "Doubling curly brackets..." messages). Only errors should be printed.
    - Returns: The preprocessed prompt (preserve leading/trailing whitespace)

File 2: pdd/prompts/load_prompt_template_python.prompt

Before:

% Inputs/Outputs
    Input: 'prompt_name' (str) - The logical name of the prompt (without '.prompt' extension)
    Returns: Optional[str] - The prompt template text, or None on error/missing file

...
    3. Return the contents of the first existing file. Print success message with prompt name.

After:

% Inputs/Outputs
    Input: 'prompt_name' (str) - The logical name of the prompt (without '.prompt' extension)
    Input: 'quiet' (bool, default False) - When True, suppress non-error output (e.g., "Successfully loaded prompt: ..." messages). Only errors should be printed.
    Returns: Optional[str] - The prompt template text, or None on error/missing file

...
    3. Return the contents of the first existing file. Print success message with prompt name if not in quiet mode.

Note on llm_invoke_python.prompt

The llm_invoke prompt already supports log-level control via environment variables (PDD_LOG_LEVEL, PDD_ENVIRONMENT). The issue there is that the CLI code doesn't set PDD_LOG_LEVEL=ERROR when --quiet is active — this is a code bug in the caller (not a prompt defect), and will be addressed in the test generation and fix phases.

Conclusion

The prompt specifications for preprocess and load_prompt_template were incomplete — they lacked quiet parameter support. The prompts have been fixed. The test generation phase will create tests based on the corrected specifications to verify that quiet=True suppresses non-error output from these modules.

Proceeding to Step 6: Test Plan

[Serhan-Asad]

Step 6: Test Plan

Existing Test Coverage

tests/test_preprocess.py (2,081 lines)

• Current coverage: Comprehensive unit tests for preprocess() — backtick includes, XML includes, shell tags, web scraping, curly bracket doubling, f-string handling, PDD tags, code block protection
• Gap: Zero tests for quiet mode. The preprocess() function currently has no quiet parameter, and no test verifies that output is suppressed when quiet is requested.

tests/test_preprocess_main.py (382 lines)

• Current coverage: Tests for preprocess_main() CLI command handler, including one quiet test (test_preprocess_main_quiet_mode) that checks the caller suppresses Rich output
• Gap: The existing quiet test only verifies preprocess_main() doesn't print — it does NOT verify that the underlying preprocess() function suppresses its own console.print() calls. Since preprocess() is mocked in that test, the 28 unconditional console.print() calls inside preprocess() are never exercised.

tests/test_load_prompt_template.py (212 lines)

• Current coverage: Tests success, missing PDD_PATH, file not found, IO error, empty/non-string prompt names, installed package fallback
• Gap: Zero tests for quiet mode. No test verifies that the "Successfully loaded prompt: ..." message is suppressed when quiet=True.

tests/test_code_generator_main.py (~3,000 lines)

• Current coverage: Comprehensive tests for code generation (local/cloud, incremental, error handling). Context fixture includes quiet: False but no test sets quiet: True and checks output.
• Gap: No tests verify that quiet mode suppresses preprocess/load_prompt_template output when called through the generate pipeline.

Proposed Tests

Test 1: test_preprocess_quiet_suppresses_rich_panels

• Input: Call preprocess(prompt, quiet=True) with a valid prompt containing include directives
• Expected: No console.print() output for "Starting prompt preprocessing", "Preprocessing complete" panels, or "Doubling curly brackets..." messages
• Actual (before fix): preprocess() has no quiet parameter — TypeError on call. Even if added, all 28 console.print() calls fire unconditionally.

Test 2: test_preprocess_quiet_false_still_prints

• Input: Call preprocess(prompt, quiet=False) with a valid prompt
• Expected: Rich panels ("Starting prompt preprocessing", "Preprocessing complete") still appear in captured output
• Actual (before fix): Passes (output is always printed)

Test 3: test_preprocess_quiet_preserves_error_output

• Input: Call preprocess("", quiet=True) (empty prompt triggers error)
• Expected: Error message "[bold red]Error:[/bold red] Empty prompt provided" still prints even in quiet mode
• Actual (before fix): preprocess() has no quiet parameter — TypeError

Test 4: test_load_prompt_template_quiet_suppresses_success_message

• Input: Call load_prompt_template("valid.prompt", quiet=True) with a valid prompt file
• Expected: No "Successfully loaded prompt: ..." message in captured output; function still returns the prompt content
• Actual (before fix): load_prompt_template() has no quiet parameter — TypeError on call

Test 5: test_load_prompt_template_quiet_preserves_error_messages

• Input: Call load_prompt_template("nonexistent.prompt", quiet=True) with a missing file
• Expected: Error message about file not found still prints even in quiet mode
• Actual (before fix): load_prompt_template() has no quiet parameter — TypeError

Test 6: test_double_curly_quiet_suppresses_progress_message

• Input: Call double_curly(text, quiet=True) with text containing single curly brackets
• Expected: No "Doubling curly brackets..." message in captured output; curly brackets still doubled correctly
• Actual (before fix): double_curly() has no quiet parameter — unconditionally prints progress

Test Location

• File: tests/test_preprocess.py (append tests 1-3, 6 — tests for preprocess() and double_curly())
• File: tests/test_load_prompt_template.py (append tests 4-5 — tests for load_prompt_template())
• Framework: pytest with capsys for output capture, unittest.mock.patch for file I/O mocking, monkeypatch for env vars

Notes

1. Mocking strategy: Tests must NOT mock preprocess() itself (unlike test_preprocess_main_quiet_mode which mocks the function and thus misses the bug). Tests must call the real preprocess() with file operations mocked.

2. Output capture: Use capsys to capture stdout. Rich console output goes to stdout by default. For console.print() calls, we may also need to patch the console object in pdd.preprocess to use a StringIO or capture its output.

3. Error vs info distinction: Tests must verify that quiet=True suppresses informational output (panels, progress messages, success messages) but preserves error output (file not found, processing errors). This is the key behavioral contract.

4. Signature compatibility: Tests 1, 3, 4, 5, 6 will fail with TypeError before the fix (function signatures don't accept quiet). This is the expected "failing test" behavior that confirms the bug exists.

5. Pattern consistency: The test approach follows the existing if not quiet: guard pattern used in 60+ places across the codebase (construct_paths.py, crash_main.py, fix_verification_main.py).

What This Test Verifies

These 6 tests verify the core bug in issue #168: the --quiet flag does not suppress output because preprocess(), double_curly(), and load_prompt_template() have no quiet parameter.

5 tests FAIL on the current buggy code with TypeError: got an unexpected keyword argument 'quiet':

Test	Failure
test_preprocess_quiet_suppresses_rich_panels	preprocess() has no quiet param
test_preprocess_quiet_preserves_error_output	preprocess() has no quiet param

Summary

Step	Result
Duplicate Check	Duplicate of #90 (7 reports total), unresolved — proceeding
Documentation	Confirmed: --quiet documented but not propagated
Triage	Proceed: clear expected/actual behavior, code area identified
Reproduction	Reproduced: 5 bug vectors confirmed
Root Cause	--quiet parsed in cli.py but never passed to preprocess.py, load_prompt_template.py, or logging
Prompt Classification	Prompt defect: prompts lack quiet parameter specification
Test Plan	6 tests planned across 2 files
Test Generation	6 tests generated: 5 fail (bug confirmed), 1 passes (regression guard)
Verification	PASS — all 5 tests fail for the correct reason (TypeError)

Bug Details

• Location: pdd/preprocess.py:113 (preprocess()), pdd/preprocess.py:453 (double_curly()), pdd/load_prompt_template.py:10 (load_prompt_template())
• Root Cause: Functions lack a quiet parameter; --quiet CLI flag is never propagated to output-producing functions
• Test Files: tests/test_preprocess.py, tests/test_load_prompt_template.py

Next Steps

1. Add quiet: bool = False parameter to preprocess(), double_curly(), and load_prompt_template()
2. Guard all console.print() calls with if not quiet: in those functions
3. Pass quiet=True from callers when CLI --quiet flag is active
4. Run the 6 new tests to confirm the fix (5 should now pass)
5. Run full test suite to check for regressions
6. Submit PR with fix and test

Step 9: E2E Test

Environment Discovery

• Repository language: Python
• Test framework: pytest (with pytest.ini and pyproject.toml markers)
• Existing E2E tests found: Yes — 36 files matching test_e2e_issue_*.py pattern
• Test configuration: pytest.ini with markers: e2e, integration, real, slow
• Fixtures/helpers used: CliRunner from click.testing, auto_update mock, conftest.py fixtures (runner, create_dummy_files, preserve_pdd_path, restore_standard_streams)
• Environment variables required: None (test creates temp prompt file, mocks LLM boundary)
• Auth/credentials: Not needed — mocked at code_generator_main boundary

E2E Test File

tests/test_e2e_issue_168_quiet_flag_output.py

Test Type

CLI (CliRunner-based, invoking full pdd.cli:cli entry point)

What This Test Verifies

When a user runs pdd --quiet --local generate <prompt_file>, the --quiet flag should suppress all non-essential output from preprocess() including Rich panels and progress messages. The test invokes the full CLI entry point and exercises the real command dispatch path: pdd.cli:cli → generate command → code_generator_main → pdd_preprocess().

Test Code

"""
E2E CLI Test for Issue #168: --quiet flag does not suppress output

Tests the full CLI path (through pdd.cli:cli entry point) to verify that
the --quiet flag suppresses non-essential output from preprocess() during
code generation.

Root cause: preprocess() has no quiet parameter, and code_generator_main
never passes the quiet flag to preprocess(). The --quiet flag is correctly
parsed in cli.py and stored in ctx.obj["quiet"], but never propagated.

E2E Test Status

PASS: E2E test correctly detects the bug

The E2E test successfully proves that the full CLI path from pdd --quiet generate through to preprocess() does not suppress output. All 3 bug indicators appear in the captured output despite --quiet:

1. Rich panel "Starting prompt preprocessing"
2. Progress message "Doubling curly brackets..."
3. Rich panel "Preprocessing complete"

Additionally, stderr captures INFO-level logging from pdd.llm_invoke which also should be suppressed in quiet mode.

Issue #168 is a duplicate of #90 ("--quiet flag does not suppress output"), the canonical/earliest report. The description is verbatim identical: pdd --quiet generate prompts/greet_python.prompt still displays INFO logs, Rich panels ("Starting prompt preprocessing", "Preprocessing complete"), "Doubling curly brackets..." messages, WARNING log lines, and "Successfully loaded prompt: ..." messages.

Issue	State	Notes
#90	OPEN	Canonical/earliest. Zero comments, no fix merged.

Proceeding to Step 2: Documentation Check

[Serhan-Asad]

Step 2: Documentation Check

Status: Confirmed Bug

Documentation Reviewed

• pdd --help CLI help text (pdd/core/cli.py lines 244-249)
• README.md — lines 603 and 1765 reference --quiet flag behavior
• CONTRIBUTING.md — no mention of --quiet flag behavior
• pdd/core/cli.py — flag definition and usage
• pdd/preprocess.py — output during preprocessing
• pdd/load_prompt_template.py — output during template loading

Findings

The --quiet flag is defined and documented in multiple places:

cli.py help text (line 248):

--quiet — Decrease output verbosity for minimal information.

README.md (line 603):

--quiet: Decrease output verbosity for minimal information.

README.md (line 1765):

--quiet: Suppress all output except errors.

The flag is properly stored in ctx.obj["quiet"] (line 333) and correctly overrides --verbose (line 362). However, the flag is not respected by downstream output-producing modules:

Modules that IGNORE quiet (root cause):

• pdd/preprocess.py — preprocess() and double_curly() have no quiet parameter; console.print() calls fire unconditionally
• pdd/load_prompt_template.py — prints "Successfully loaded prompt: ..." unconditionally
• Python logging module — INFO/WARNING log levels are never adjusted when --quiet is set

Verdict: The documented behavior clearly states --quiet should suppress output, but downstream modules ignore the flag entirely. The code does not match its documented behavior.

---

Proceeding to Step 3: Triage

[Serhan-Asad]

Step 3: Triage

Status: Proceed

Summary

We have all the information needed to reproduce and fix this issue:

• Expected behavior: --quiet should suppress all non-essential output (INFO logs, Rich panels, warnings). Only errors and the final result should be shown.
• Actual behavior: Full verbose-style output including INFO logs, Rich panels ("Starting prompt preprocessing", "Preprocessing complete"), "Doubling curly brackets..." messages, and WARNING log lines appear despite --quiet.
• Reproduction steps: Clear and simple — pdd --quiet generate prompts/greet_python.prompt.
• Code area identified: The --quiet flag is properly defined and propagated in pdd/core/cli.py (stored in ctx.obj["quiet"]), and cli.py itself checks it before printing. However, downstream modules like pdd/preprocess.py contain numerous unconditional console.print() calls (Panels, status messages, debug info) that never check the quiet flag. This is the root cause — output-producing modules bypass the quiet check.

This is a well-documented, frequently reported issue (7 duplicates) with a clear reproduction path and identified code areas.
