dex-whats-newShow recent system improvements — captured learnings plus new Claude capabilities.
Dex Whats New is an agent skill from davekilleen/Dex. Show recent system improvements — captured learnings plus new Claude capabilities. Use when the user says 'what's new', 'any updates to how Dex works'. Not for previewing and applying a version update; use dex-update. Not for unused existing features; use dex-level-up.
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Changelog and release notes. The repository describes itself as: Your AI Chief of Staff — a personal operating system starter kit that adapts to your role. No coding required. The licence is MIT.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit d0ffc6b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Dex Whats New loads about 2.9k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 822 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
The full file from davekilleen/Dex at commit d0ffc6b, republished under its MIT licence (© davekilleen). 822 words, ~2,898 tokens.

/dex-improve — Full design partner (includes this + workshopping + audit)/create-mcp — Build new integrations when new MCP features enable themCall the mark_feature_used tool on the dex-analytics MCP server with dex-whats-new. This ticks the feature's box in System/usage_log.md, which is what /dex-level-up reads to recommend features that have not been tried. It writes locally and sends nothing, so it runs whether or not analytics is enabled.
Analytics (Silent):
Call track_event with event_name whats_new_viewed and properties:
update_available (boolean)This only fires if the user has opted into analytics. No action needed if it returns "analytics_disabled".

Dex Whats New fits situations like: the user says whats new; any updates to how Dex works.
Run `npx skills add davekilleen/Dex --skill dex-whats-new -a claude-code`. Or copy the skill folder (.agents/skills/dex-whats-new in davekilleen/Dex) into .claude/skills/dex-whats-new in your project. Claude Code loads it when a task matches its description.
Run `npx skills add davekilleen/Dex --skill dex-whats-new -a codex`. Or copy the skill folder (.agents/skills/dex-whats-new in davekilleen/Dex) into .agents/skills/dex-whats-new in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add davekilleen/Dex --skill dex-whats-new -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/dex-whats-new, .gemini/skills/dex-whats-new, .github/skills/dex-whats-new and .opencode/skills/dex-whats-new in your project.
SKILL.md names no scripts, command-line tools or credentials: Dex Whats New is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Dex Whats New is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.9k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Dex Whats New: Simple English (moeru-ai/airi, 50k stars), StarRocks Release Notes (StarRocks/starrocks, 12k stars), Cutting A Release (TriliumNext/Trilium, 38k stars) and Rea Changelog Update (morluto/rea, 80k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
