Surface unaddressed threads from the conversation — bugs mentioned but not fixed, deferred decisions, dropped nits, cross-workstream dependencies, unverified claims, and promised-but-not-done items — as a tight, skimmable report. Reports; never edits code. Use when the user says "loose ends", "any loose ends", "what did we leave hanging", "what didn't we get to", "what got dropped", "open threads", "unaddressed items", "what did we punt on", or "/loose-ends".
Answer in a simple, concise voice, no filler or hedging. Persisted per project or per user, in prose-only, prose+code, or laconic-code (code-first) mode. A per-turn reminder refocuses the voice mid-session (cadence configurable). Invoke via /laconic (on|off|status|mode|cadence).
One skill for committing work and opening PRs, built around stacked PRs. Bare /pr (or $pr in Codex) checkpoints the current diff as the next branch in a stack; subcommands publish the stack (submit), rebase it onto trunk (sync), walk every PR as annotatable Markdown plus exact patches (walk), and land it bottom-up (merge). Update covers the single-branch case — commit and refresh the current branch's PR. Any PR can be opened as a draft with --draft (-d), or make drafts the default with setup. Also ships an optional diff-size nudge hook when the uncommitted diff grows large; enable it explicitly with setup nudge. Agent-callable — an agent working through a task should invoke this to ship a finished slice — `checkpoint`/`commit` at each logical seam to land a stacked PR and continue on a fresh branch, or `update` to commit and refresh the current branch's single PR. Reach for it when a unit of work is complete or the user asks to commit, push, checkpoint, open a PR, or review/walk a PR stack. Do not autonomousl
Blocks destructive git commands (reset --hard, push --force, clean -f, checkout <path>, branch -D, stash drop/clear, worktree remove --force) in Claude Code while letting safer alternatives (--force-with-lease, --soft/--mixed, restore, branch -d) through. PreToolUse hook on Bash. Frontmatter block fires only when this skill is active in context; run `scripts/install.sh` after `npx skills add` for always-on protection.
Retrieve authoritative, up-to-date documentation, API references, configuration details, and code examples for any developer technology (libraries, frameworks, languages, SDKs, APIs, CLI tools, cloud services) via the Context7 CLI. Use whenever answering technical questions or writing code that interacts with external technologies, or when documentation accuracy matters and model knowledge may be outdated.
Manage the repo's project-tracker kanban board as one skill, over a pluggable backend (GitHub Projects or Linear). Subcommands bootstrap a board (setup), pick the next Todo card (next), create a card (new-task), edit a card (update), audit board accuracy against the codebase (audit), split a big card into subtasks (decompose), remove a card (delete), group work into a milestone (milestone), apply one operation across many cards at once (batch), and walk a scope of cards one by one for per-card decisions informed by codebase context (walk). Use when the user says "/project", "what's next", "new task", "add a card", "update card N", "audit the board", "decompose this card", "delete card N", "create a milestone", "add this to the milestone", "what's next in the milestone", "create these five tickets", "delete cards 12, 14, 19", "/project batch", "walk me through the milestone", "triage these cards", "groom the backlog one by one", or "/project walk".

Generate arbitrary graphic assets using Google's Nano Banana (Gemini image generation API).
export GEMINI_API_KEY="your-api-key"
The script reads the key from the environment only — never hard-code it or pass it as an argument.
# Basic usage - provide a prompt
bun "${CLAUDE_SKILL_DIR}/scripts/generate.ts" "Art Deco logo for City Tycoon game"
# Specify output path
bun "${CLAUDE_SKILL_DIR}/scripts/generate.ts" "icon of a golden skyscraper" --output ./logo.png
# Specify dimensions (mapped to the nearest supported aspect ratio and output size)
bun "${CLAUDE_SKILL_DIR}/scripts/generate.ts" "game title banner" --width 800 --height 200
# Use the faster Nano Banana 2 model
bun "${CLAUDE_SKILL_DIR}/scripts/generate.ts" "quick concept" --model nano-banana-2
# Request transparent background
bun "${CLAUDE_SKILL_DIR}/scripts/generate.ts" "app icon" --transparent
# Image-to-image editing
bun "${CLAUDE_SKILL_DIR}/scripts/generate.ts" "add flowers to grass" --input ./grass.png --output ./grass_flowers.png
| Option | Short | Description |
|---|---|---|
--output <path> | -o | Output file path (default: ./output.png) |
--input <path> | -i | Input image for image-to-image editing |
--width <px> | -w | Desired image width; selects the nearest supported aspect ratio and output size (default: 512) |
--height <px> | -h | Desired image height; selects the nearest supported aspect ratio and output size (default: 512) |
--model <name> | -m | Model: nano-banana-pro (default, best quality) or nano-banana-2 (faster) |
--transparent | -t | Request transparent PNG background |
--style <desc> | -s | Add style modifier to prompt |
--help | Show help |
| Model | ID | Best For |
|---|---|---|
| Nano Banana Pro (default) | gemini-3-pro-image | Professional-grade final assets and highest quality |
| Nano Banana 2 | gemini-3.1-flash-image | Fast, high-volume generation and iteration |
The helper uses Google's stable generateContent API with its current native
image configuration and maps --width and --height to the nearest supported
aspect ratio and model-supported output size. Nano Banana Pro supports 1K,
2K, and 4K; Nano Banana 2 additionally supports 512. Generated dimensions
can differ from the exact requested pixel values.
