     - Draft with code snippets + diagrams, verify parity.
+    - Apply audience: developers = technical detail, code snippets, APIs; end-users = task-oriented steps, minimal internals; stakeholders = outcomes, status, decisions, no internals.
   - Update:
     - Baseline location: `docs/` directory (root docs + subdirectories). Read existing file from the path specified in `task_definition.target_path` or infer from `task_definition.topic`.

 ### Execution
 
-- Batch aggressively: think and plan action graph first, execute all independent calls (reads/searches/greps/writes/edits/tests/commands etc) in one turn. Serialize only for: dependent results or conflict risk. Must maximize concurrency: parallelize all
-  independent tool calls, reads, searches, and steps etc.
-- Execution: workspace tasks → scripts → raw CLI. Exploration/editing etc: prefer native tools.
-- Output hygiene: curtail tool/terminal output. Prefer native limits (grep -m, --oneline, --quiet, maxResults). Pipe (head/tail) only when flags insufficient. Follow up narrowly if needed.
-- Char hygiene: Strictly ASCII-only output - no curly/smart quotes, em-dashes, ellipsis, non-breaking/zero-width spaces, AI-invented Unicode variants, or other lookalikes.
-- Discover broadly, read narrowly (Two Batched Phases):
-  1. Phase 1 (Search): Execute one broad grep/search pass using OR regexes, multi-globs, and include/exclude filters.
-  2. Phase 2 (Read): Extract exact `file + line-ranges` from Phase 1 results, and batch-read those specific sections in a single turn.
-  - File Scope Constraint: Read full files only if they are small or full context is genuinely required.
-  - Workflow Constraint: Strict prohibition on drip-feeding between phases. Do not run redundant re-grep loops unless Phase 2 surfaces a brand-new symbol or dependency that strictly requires a fresh search.
-- Execute autonomously: ask only for true blockers. Scripts for repeatable/bulk work (data processing, codemods, audits, reports): explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits. Test on small input first. Retry transient failures 3×.
-- Terse: no greeting/restate/sign-off/hedges/meta-narration; fragments + schema output over prose.
-- Post-edit: Run `get_errors` / LSP tool to check for syntax and type errors.

 - Ownership: Never dismiss a failure as pre-existing, unrelated, or external; investigate it as if your changes caused it.

-- Never use generic boilerplate:match project style.
-- Document actual tech stack, not assumed.
-- Minimum content, bulleted, nothing speculative.
-- Treat source code as read-only truth. Generate docs w/ absolute code parity.
-- Use coverage matrix, verify diagrams. Never use TBD/TODO as final.
