skills

Personal Agent Skills by @vdsmon, packaged as a plugin marketplace. Most run on any SKILL.md-native host, and a few are Claude-Code-specific.

Each skill ships as its own plugin so you can install only what you want.

Naming convention

Plugins prefixed with cc- are Claude-Code-specific: they use features (SessionStart hooks, !`cmd` dynamic context injection, ${CLAUDE_SKILL_DIR}, context: fork) that don't exist on other Agent Skills hosts.

Plugins without the cc- prefix are portable. They follow the open Agent Skills format and work on any SKILL.md-native host: Claude Code, OpenAI Codex CLI, Gemini CLI, Cursor, Goose, OpenCode, Copilot, Amp, Roo Code, and many more.

The Plugins table below lists every plugin and its host: Host: CC only is a cc- plugin, Host: any is portable.

Install on Claude Code

Register the marketplace once:

/plugin marketplace add vdsmon/skills

Install any plugin by name (see the Plugins table for the full list):

/plugin install <name>@vdsmon-skills

Or run /plugins and pick from the interactive browser.

Install on OpenAI Codex CLI

This repo ships a native Codex plugin marketplace (.agents/plugins/marketplace.json), so you install the same way Claude Code does: register once, then pick plugins. Only the portable (non-cc-) plugins are listed, since the cc- plugins rely on Claude-Code-only features and won't run on Codex.

codex plugin marketplace add vdsmon/skills

Then browse and install from the interactive picker:

/plugins

Select a plugin and choose Install plugin (Space toggles enabled state).

Skills that only run on a /slash call in Claude Code stay manual on Codex too: Codex never picks them on its own, so call them with $<skill>.

Install on other hosts (portable plugins only)

Clone this repo and copy the skill folder into the host's skills directory. Each host's path is listed at agentskills.io/clients.

git clone https://github.com/vdsmon/skills
cp -r skills/plugins/<plugin>/skills/<skill> <host-skills-dir>/

Plugins

Generated from each plugin's plugin.json by scripts/sync-codex.sh, so do not hand-edit between the markers. Host: any is portable, Host: CC only needs Claude Code. Run /plugins for the full descriptions and triggers.

Plugin	Host	What it does
slack-draft	any	Draft a Slack message for the user to send: Slack mrkdwn, lead-with-conclusion, backticked identifiers and domain values, ASCII punctuation.
skill-polish	any	Post-mortem for any skill: finds friction in a session, traces it to the responsible skill file, and edits that file's source checkout, not the plugin install copy.
cc-keepwarm	CC only	Keeps Claude Code's prompt cache warm in every session with a silent background ping timed from your last request, and skips the ping once the cache is already gone.
cc-timeline	CC only	A side pane that draws each Claude Code turn as a timeline: every tool call is a colored bar on the turn's time axis, with subagent calls under their Agent call.
cc-wrap-up	CC only	Cues a wrap-up at a natural break in a long session, then compacts with prep-compact's message or hands off with prep-exit's resume prompt, with no copy-paste.
cc-pitstop	CC only	Pauses Claude Code before the 5-hour or weekly usage limit, across every session on the machine, and resumes the paused work on its own when the window resets.
cc-quiet-watch	CC only	Watches long jobs on a timer and asks Haiku only when the output changed. It wakes the session only when the job is done, failed, stuck or needs you.
cc-turn-review	CC only	After each turn that changes files in a git repo, Haiku checks the diff for over-design and for comment and prose rules, and a band offers to fix what it finds.
cc-changes	CC only	A side pane that lists every file the Claude Code session created, edited or deleted, with net line counts, and shows a file's diff when you press it.
prep-compact	any	Audit in-flight session state before compaction truncates history, and save what would be lost.
prep-exit	any	Save what only the conversation knows before a session ends, so a fresh session can pick up the work.
prep-goal	any	Interrogate a rough objective into a tight, verifiable /goal completion condition before handing it to an autonomous goal loop.
humanize	any	Strip AI-writing tells from text. Detects em-dash overuse, AI vocabulary, inflated significance, rule-of-three, sycophancy, compound coinages, and 20+ more patterns.
brainstorming	any	Design-before-code gate that sizes each request as a spike, a bounded change, or architectural work, and gets approval on a design before any code.
systematic-debugging	any	Four-phase debugging discipline (root-cause investigation, pattern analysis, hypothesis, single-fix implementation).
git-cleanup	any	Removes local git branches and worktrees that are safely merged into dev/develop/master/main, skipping dirty worktrees and the main checkout.
strip-migration-cruft	any	Finds comments and docs that narrate past project history (phase, wave, story, migration notes), sorts cruft from live meaning, and strips the cruft after confirmation.
grilling	any	Relentless interview that stress-tests a plan, decision, or idea one round of questions at a time, until you and the agent agree.
teach	any	Stateful, multi-session teaching workspace that turns a topic into short HTML lessons built for long-term retention.
codebase-design	any	Shared vocabulary for designing deep modules: a lot of behaviour behind a small interface, placed at a clean seam, testable through that interface.
question	any	Answer a genuine question in full, with no edits and no side effects. Treats 'why X and not Y?' as curiosity, not as a hidden request to switch to Y or an attack on X.
open-pr	any	Write a short, plain pull request description a teammate reads in a minute: what changes, why now, what they must do.
start-work	any	Start each job in its own git worktree, based on a fresh fetch of the remote, without switching the main checkout.
cc-autotitle	CC only	Names each Claude Code session on its own: after a few turns it picks a short kebab-case name from the whole session, and renames it again when the work moves on.
cc-dazzle	CC only	Draws Claude Code's transcript in Catppuccin Mocha: boxed code blocks, box tables, Mermaid diagrams, diff cards in Claude's colors, compact tool rows and timed prompts.

You write plugin.json and the skills. scripts/sync-codex.sh generates the rest: the Codex marketplace and symlinks, each marketplace entry's description and version, and the Plugins table above. CI fails a pull request that did not run it.
