From f16403a17e28b395e3a107fe46d5d13e1574af2c Mon Sep 17 00:00:00 2001 From: AutoShorts Bot Date: Thu, 30 Jul 2026 19:17:43 +0000 Subject: [PATCH 1/2] feat: implement Hook Engine with 7 viral hook styles - Add HookEngine module with HookStyle enum (default, curiosity, counter, controversy, challenge, reveal, story) - Implement 21 hook templates based on proven copywriting frameworks (Triple Hook, Curiosity Gap, Pattern Interrupt, Counter-Narrative, Hormozi storytelling) - Integrate HookEngine into ScriptGenerator with hook_style param, enhanced tone instructions, and first-paragraph injection - Update ExplainerGenerator to accept and propagate hook_style - Add --hook-style/-hs CLI option to explainer command - Fix help_cmd.py Group detection for newer typer versions (fixes 3 failing CLI tests) - Add 16 comprehensive tests in test_hook_engine.py covering all styles, quality guards, and performance - Update README with Hook Styles documentation and usage examples - Backward compatible: DEFAULT preserves existing behavior (empty hook) - Performance: hook generation <2s total for 10 runs --- IMPLEMENTATION_SUMMARY.md | 123 +++++ README.md | 47 +- src/autoshorts/cli/commands/explainer.py | 12 +- src/autoshorts/cli/commands/help_cmd.py | 10 +- src/autoshorts/generators/explainer.py | 4 + src/autoshorts/modules/__init__.py | 3 + src/autoshorts/modules/hook_engine.py | 524 +++++++++++++++++++++ src/autoshorts/modules/script_generator.py | 342 +++++++++----- tests/test_hook_engine.py | 154 ++++++ 9 files changed, 1106 insertions(+), 113 deletions(-) create mode 100644 IMPLEMENTATION_SUMMARY.md create mode 100644 src/autoshorts/modules/hook_engine.py create mode 100644 tests/test_hook_engine.py diff --git a/IMPLEMENTATION_SUMMARY.md b/IMPLEMENTATION_SUMMARY.md new file mode 100644 index 0000000..cbff169 --- /dev/null +++ b/IMPLEMENTATION_SUMMARY.md @@ -0,0 +1,123 @@ +# AutoShorts Hook Engine Feature -

Bot Date: Thu, 30 Jul 2026 19:55:13 +0000 Subject: [PATCH 2/2] =?UTF-8?q?fix:=20address=20PR=20review=20=E2=80=94=20?= =?UTF-8?q?verification=20bypass,=20hallucinated=20years,=20cleanup?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Critical: - Fix verification bypass: hook now injected BEFORE _verify_factual_claims and NOT re-injected after, preserving fact-checked corrections - Remove second injection in generate_script and generate_script_with_prompts that overwrote verified hook - _generate_script_with_context no longer injects hook internally — caller handles injection via _inject_hook (DRY) High: - Fix hallucinated facts: _extract_year now returns None if no year in subject OR context (no random 1950-2023) - Prefer templates without [YEAR] when year is None to avoid inventing dates; when year found in context, templates with year are used - _TEMPLATES_INFO now actually used as source for hook generation via _fill_template, not dead code - _number_for_subject tries to extract number from context for structural uses, still random only for non-factual 'N razões' templates Medium: - Simplify help_cmd.py: hasattr(target, 'commands') instead of redundant has_commands logic - Remove IMPLEMENTATION_SUMMARY.md (internal notes) from repo - Encoding: keep UTF-8 but minimize diff noise Low: - CLI: add case_sensitive=False to --hook-style for case-insensitive parsing - Add logging WARNING when invalid style falls back to DEFAULT - DRY: consistently use _inject_hook() everywhere instead of manual injection - Add 5 new CLI tests: hook_style flag shows in help, valid styles, short flag, invalid, case-insensitive Tests: - 53 passed (16 hook_engine + 37 CLI) vs previously 32 — new tests pass - Verification bypass reproduction test passes (verified hook preserved) - No hallucinated year test: Pelé 1000 gols without context produces no random year --- IMPLEMENTATION_SUMMARY.md | 123 --------
