From efd71ae83cab49d2d31b1bbf0cfa289394c2f9b3 Mon Sep 17 00:00:00 2001 From: uday chauhan Date: Tue, 7 Apr 2026 02:17:49 +0530 Subject: [PATCH 01/21] feat(infra): add BaseAgent, tools registry, and skill files - agent_base.py: BaseAgent with use() (tool dispatch) and think() (sole LLM entry point). Skill files drive system prompts. Lazy LLM init. - tools/__init__.py: @register decorator + call() for named tool dispatch. Auto-imports seo and content modules on first load. - tools/seo.py: 6 pure-Python SEO tools (title, meta, keywords, headings, code_blocks, full). seo.full returns score 0-100. - tools/content.py: 6 pure-Python content tools (word_count, headings, code_blocks, hook, paragraphs, structure_summary). - skills/draft.md: WriterAgent system prompt v1.0 (narrative arc only). - skills/critic.md: CriticAgent system prompt v1.0 (4-dimension scoring). - skills/boost.md: BlogBoostAgent system prompt v1.0. - TODOS.md: added PIPE-1 (pipeline mode flag) and SEO-1 (consolidate boost_eval.py) as deferred work items.

Orchestrator now accepts PipelineAgents injection. SEOAgent fast-paths score>=85 on first pass. skills/seo.md and skills/structurer.md added. revision_attempt field added to BlogJob. CriticAgent refactored to extend BaseAgent. tenacity retry added to BaseAgent for 429/5xx. Tests updated for new injection pattern and structured output schemas.

These fields are read in _parse() but were missing from the Gemini structured output schema — causing WP posts to silently get no tags or categories. GAP-3: Add seo_score to BlogJob. SEOAgent stamps it on every returned job (fast path and LLM path). CriticAgent maps it to seo_quality 1–5 via _seo_score_to_quality(), overriding the LLM-derived value deterministically. GAP-4: CriticAgent computes publish_readiness from draft_body_md signals (word count, headings, code blocks, CTA) via _compute_publish_readiness(). Always overrides LLM-derived value. Eliminates 2 dimensions of LLM hallucination in scoring. 631 tests passing.
