README

bin-stack

A harness-agnostic agent skill stack.

Skills follow the Agent Skills format (SKILL.md + optional scripts/references/assets). One source of truth under skills/. Works with Cursor, Claude Code, Codex, and any other agent that discovers skills the standard way.

Inspired by stacks like pstack, but not locked to a single product.

Install

Via skills CLI

npx skills add binbandit/bin-stack

Pick specific skills:

npx skills add binbandit/bin-stack --skill file-pr --skill babysit-pr --skill arena --skill bro

Symlink a clone (one copy, every harness)

git clone https://github.com/binbandit/bin-stack.git ~/Developer/ai/bin-stack
cd ~/Developer/ai/bin-stack
./scripts/link-skills.sh

That links each skill directory into the harness roots you already have (~/.agents/skills, ~/.cursor/skills, ~/.claude/skills, ~/.codex/skills, …). Edit here; every harness sees the same files.

Skills

Skill	When to use
`file-pr`	File or update a concise pull request
`babysit-pr`	Monitor a PR through review bots and CI
`arena`	Run competing attempts, then graft the strongest ideas into one result
`bro`	Restate the last message in plain language
`verify`	Prove a behavior change on the user surface with revision-bound evidence
`review`	Filter adversarial findings by reachable failure and concrete evidence

Mods

Claude Code mods: plugins of function hooks that change how Claude Code looks and behaves. They are Claude Code only.

Mod	What it does
`glamour-dark`	Draws replies as rich markdown in glamour's dark style, one sentence per line
`marathon-footer`	Restyles the hints after the mode label under the prompt to match the SLOPOTHON banner: `⏵⏵ auto mode on · ⇧⇥ CYCLE // ← 1 AGENT`
`redact-secrets`	Swaps secrets for placeholders before Claude reads them or the session logs them; Write and Edit put the real values back
`tool-lines`	Draws each tool call as one compact line and hides its result block
`ascii-spinner`	Swaps the working line (verb, timer, tokens, effort, tip) for a one-row WEAVEworm rethreading synthsilk, in Sekiguchi colors
`slopothon`	Paints a SLOPOTHON lockup over the Claude logo in Marathon's design language: block wordmark, a dot-matrix card naming the model and branch, and a livery strip with a tagline and barcode per session. Fullscreen (`"tui": "fullscreen"`) only; it starts each session with a `/slopothon` row and the logo shows for ~130ms first. Type `/slopothon` to redraw it inline

Install every mod at user scope:

./scripts/install-mods.sh

The script adds mods/ as the bin-stack marketplace and installs each mod from it. Claude Code reads the mods in place from this clone, so an edit here applies on the next session or /reload-plugins. Re-run it after adding a mod.

Canonical skills live in skills/. Harness-specific paths are adapters (symlinks or CLI installs), not forks of the content.

Authoring

Add skills/<name>/SKILL.md with required name and description frontmatter.
Keep name matching the directory. Lowercase, hyphens only.
Put long reference material in references/; keep SKILL.md short enough to load on activation.
Prefer harness-neutral wording. Call out Cursor / Claude / Codex only when a step truly differs.

See agentskills.io/specification.

The verify and review skills adapt selected pstack guidance by Lauren Tan at revision 9f451cf875ad1239912762f67741e8e5ba6ac0f1. Each skill bundles its provenance and the original MIT notice in LICENSE-pstack so attribution travels with individual skill installs.
