fix: prevent plan mode layering with planning skills

Bot consistently enters EnterPlanMode before invoking writing-plans,
creating redundant approval gates and read-only restrictions. Add
red flag entry to using-superpowers and explicit warning to
writing-plans skill.

-REM ============================================================================
-REM DEPRECATED: This polyglot wrapper is no longer used as of Claude Code 2.1.x
-REM ============================================================================
+REM Cross-platform polyglot wrapper for hook scripts.
+REM On Windows: cmd.exe runs the batch portion, which finds and calls bash.
+REM On Unix: the shell interprets this as a script (: is a no-op in bash).
 REM
-REM Claude Code 2.1.x changed the Windows execution model for hooks:
+REM Hook scripts use extensionless filenames (e.g. "session-start" not
+REM "session-start.sh") so Claude Code's Windows auto-detection -- which
+REM prepends "bash" to any command containing .sh -- doesn't interfere.
 REM
-REM   Before (2.0.x): Hooks ran with shell:true, using the system default shell.
-REM                   This wrapper provided cross-platform compatibility by
-REM                   being both a valid .cmd file (Windows) and bash script.
-REM
-REM   After (2.1.x):  Claude Code now auto-detects .sh files in hook commands
-REM                   and prepends "bash " on Windows. This broke the wrapper
-REM                   because the command:
-REM                     "run-hook.cmd" session-start.sh
-REM                   became:
-REM                     bash "run-hook.cmd" session-start.sh
-REM                   ...and bash cannot execute a .cmd file.
-REM
-REM The fix: hooks.json now calls session-start.sh directly. Claude Code 2.1.x
-REM handles the bash invocation automatically on Windows.
-REM
-REM This file is kept for reference and potential backward compatibility.

 # Writing Plans
 
+**IMPORTANT:** Invoke this skill directly — do NOT use EnterPlanMode or platform plan mode. This skill has its own workflow and approval checkpoint (execution handoff). Layering plan mode on top is redundant and restrictive.
+
 ## Overview
 
 Write comprehensive implementation plans assuming the engineer has zero context for our codebase and questionable taste. Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.

-# Test: Brainstorm-to-plan handoff
-#
-# Verifies that after brainstorming, Claude invokes the writing-plans skill
-# instead of using EnterPlanMode.
-#
-# The failure mode this catches:
-#   User says "build it" after brainstorming -> Claude calls EnterPlanMode
-#   (because the system prompt's planning guidance overpowers the brainstorming
-#   skill's instructions, which were loaded many turns ago)
-#
-# PASS: Skill tool invoked with "writing-plans" AND EnterPlanMode NOT invoked
-# FAIL: EnterPlanMode invoked OR writing-plans not invoked
-#
-# Usage:
-#   ./test-brainstorm-handoff.sh                  # Normal test (expects PASS)
-#   ./test-brainstorm-handoff.sh --without-fix    # Strip fix, reproduce failure
-#   ./test-brainstorm-handoff.sh --verbose        # Show full output

-# URL Shortener Design Spec
-
-## Overview
-Add URL shortening capability to the existing Express.js API.
-
-## Features
-- POST /api/shorten accepts { url } and returns { shortCode, shortUrl }
-- GET /:code redirects to the original URL (302)
-- GET /api/stats/:code returns { clicks, createdAt, originalUrl }
-
-## Technical Design
-
-### Database
-Single SQLite table via better-sqlite3:
-```sql
-CREATE TABLE urls (
-  id INTEGER PRIMARY KEY AUTOINCREMENT,
-  short_code TEXT UNIQUE NOT NULL,
-  original_url TEXT NOT NULL,
-  clicks INTEGER DEFAULT 0,
-  created_at TEXT DEFAULT (datetime('now'))
-);
-CREATE INDEX idx_short_code ON urls(short_code);
-```
-
-### File Structure
-- `src/index.js` — modified to mount new routes
-- `src/db.js` — database initialization and query functions
-- `src/shorten.js` — route handlers for all three endpoints
-- `src/code-generator.js` — random 6-char alphanumeric code generation
-
-### Code Generation
-Random 6-character alphanumeric codes using crypto.randomBytes.
-Check for collisions and retry (astronomically unlikely with 36^6 space).
-
-### Validation
-- URL must be present and start with http:// or https://
-- Return 400 with { error: "..." } for invalid input
-
-### Error Handling
-- 404 with { error: "Not found" } for unknown short codes
-- 500 with { error: "Internal server error" } for database failures
-
-## Decisions
-- 302 redirects (not 301) so browsers don't cache and we always track clicks
-- Database path configurable via DATABASE_PATH env var, defaults to ./data/urls.db
-- No auth, no custom codes, no expiry — keeping it simple
