spaceman1412 fd4c3c2fc7 Add new skills and utilities for enhanced writing and testing

- Introduced graphviz conventions for visualizing process flows in writing skills.
- Added a comprehensive guide on persuasion principles to improve skill design effectiveness.
- Implemented a script to render graphviz diagrams from markdown files to SVG format.
- Created a detailed reference for testing skills with subagents, emphasizing TDD principles.
- Established a task tracker template for live task management.
- Developed a shell script to check the integrity of the antigravity profile and required files.
- Added test scripts to validate the initialization of agent projects.
- Created workflows for brainstorming, executing plans, and writing plans to streamline processes.

Antigravity Port Differences vs Original Superpowers

This document lists the current differences between:

Original skill set: skills/
Antigravity port: templates/.agent/skills/ (+ Antigravity profile docs/tests)

1) High-Level Delta

Skill count changed from 14 (original) to 13 (port).
Port keeps 12 original skill names, removes 2, and adds:
- single-flow-task-execution (new Antigravity-only execution skill, consolidates content from the removed dispatching-parallel-agents and subagent-driven-development)
Removed skills:
- dispatching-parallel-agents — decomposition pattern merged into single-flow-task-execution
- subagent-driven-development — two-stage review loop merged into single-flow-task-execution
Core model changed from generic subagent/parallel coding to single-flow task execution.
Generic coding subagent usage is replaced with:
- task_boundary for coding tasks
- browser_subagent only for browser automation
Legacy platform/tool vocabulary was translated to Antigravity equivalents:
- Claude/Claude Code -> Antigravity
- Skill tool -> view_file
- TodoWrite -> update <project-root>/docs/plans/task.md
- superpowers:<skill> references -> local .agent/skills/.../SKILL.md

2) Task Tracking Model Differences

Original skills used TodoWrite semantics.
Port uses project runtime file: <project-root>/docs/plans/task.md.
Port includes .agent/task.md as a template/instruction reference only.
Live tracker requirements in the port:
- lives at project root docs/plans/task.md
- table-only tracker (no prose/instructions)
- not packaged as templates/.agent/docs/plans/task.md

3) Skill-by-Skill Differences

Major Behavioral Rewrites

single-flow-task-execution (NEW — consolidated from 3 sources)
- Merges content from original dispatching-parallel-agents (task decomposition + queuing) and subagent-driven-development (two-stage review loop).
- Strict single-flow execution with task_boundary, review gates retained.
- Progress tracking via <project-root>/docs/plans/task.md.
- Review prompt templates (implementer-prompt.md, spec-reviewer-prompt.md, code-quality-reviewer-prompt.md) moved into this skill directory.
requesting-code-review
- Original: dispatches superpowers:code-reviewer subagent.
- Port: checklist-based structured review flow (no generic coding subagent dispatch).
- Integration text updated to single-flow wording.
writing-plans
- Original handoff: subagent-driven vs parallel-session via superpowers:*.
- Port handoff: single-flow-task-execution vs .agent/skills/executing-plans/SKILL.md.
- Plan header updated for Antigravity-required execution skill path.
executing-plans
- Original: creates/uses TodoWrite; integrates with superpowers:* skills.
- Port: updates <project-root>/docs/plans/task.md and uses local .agent/skills references.
- Adds explicit task_boundary/browser_subagent execution rule.

Targeted Adaptations (Not Full Rewrites)

using-superpowers
- Skill loading switched to view_file.
- Checklist tracking switched to project-root docs/plans/task.md.
- Adds explicit instruction to create tracker file if missing (table-only format).
writing-skills
- Platform references and personal skill paths changed to Antigravity style.
- Required background references changed from superpowers:* to local .agent/skills paths.
- Checklist tracking text updated to project-root table-only tracker.
systematic-debugging
- Related skill references changed from superpowers:* to local .agent/skills/....
- Support creation log path references normalized away from Claude-specific location.
using-git-worktrees
- Directory preference source changed from CLAUDE.md to .agent/AGENTS.md.
receiving-code-review
- Style violation example changed from CLAUDE.md violation to .agent/AGENTS.md violation.
writing-skills/persuasion-principles.md
- TodoWrite examples updated to <project-root>/docs/plans/task.md tracking wording.

Mostly Preserved Skills (Behavior Intact, Terminology/Path Normalization)

brainstorming
test-driven-development
verification-before-completion
finishing-a-development-branch

These keep the original core process intent, with Antigravity naming/path normalization where needed.

4) Renamed Supporting Files in `writing-skills`

anthropic-best-practices.md -> antigravity-best-practices.md
examples/CLAUDE_MD_TESTING.md -> examples/AGENTS_MD_TESTING.md

5) Antigravity-Only Profile Files Added

Compared to original skills/-only set, the port adds profile scaffolding:

.agent/AGENTS.md (tool translation + execution contract)
.agent/INSTALL.md (installation for target projects)
.agent/task.md (template/reference)
.agent/tests/check-antigravity-profile.sh
.agent/tests/run-tests.sh
README.md
CURRENT-FLOW.md

6) Validation/Guardrail Differences

The Antigravity port adds automated profile checks that the original skill library does not include:

Required skill/doc presence checks
Frontmatter validation (name, description)
Legacy-instruction pattern detection (e.g., old superpowers:/Task tool phrasing)
AGENTS mapping contract checks
Guard that packaged runtime tracker (templates/.agent/docs/plans/task.md) is absent
