What it does

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.

When your agent uses it

  • The user says whats new
  • Any updates to how Dex works

Example prompts

  • “any updates to how Dex works”
  • “/dex-whats-new”

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Review Session Learnings (Unless --claude flag)
  2. Read Current State (Unless --learnings flag)
  3. Fetch Current Changelog
  4. Compare and Surface Changes
  5. Present Claude Findings
  6. Update State
  7. Backlog Synthesis (NEW — Innovation Concierge)

What it can do on your machine

Read from SKILL.md and the folder at commit d0ffc6b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    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.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

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.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k

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.

Safety

Auto-check passed

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.

Check for improvements to your Dex system from TWO sources:

  1. Learnings from your usage - Mistakes, patterns, opportunities captured during sessions
  2. New Claude Code capabilities - Features that could enhance your workflows

Usage

/dex-whats-new              # Review learnings + check for Claude updates
/dex-whats-new --full       # Include detailed explanations
/dex-whats-new --learnings  # Only review session learnings
/dex-whats-new --claude     # Only check Claude Code updates

Arguments

$MODE: Optional flags

  • --full - Detailed explanations of each feature
  • --learnings - Only review learnings (skip Claude check)
  • --claude - Only check Claude updates (skip learnings)

Process

Step 0: Review Session Learnings (Unless --claude flag)

Check for learnings to review:

  1. Read files in System/Session_Learnings/ from last 30 days
  2. Read 06-Resources/Learnings/Mistake_Patterns.md - check for new patterns
  3. Read 06-Resources/Learnings/Working_Preferences.md - check for trends

Extract improvement opportunities:

  • Recurring mistakes → suggest preventive measures
  • Gaps in documentation → suggest additions
  • Workflow inefficiencies → suggest automations
  • User patterns → suggest customizations

Present findings:

2. [Improvement name]
   ...

Want me to implement any of these? (Enter number)

If no learnings: Skip this section or show: "No session learnings captured yet. The system will learn as you use it."


Step 1: Read Current State (Unless --learnings flag)

Load System/claude-code-state.json:

json
{
  "last_check": "2026-01-15",
  "last_version_seen": "1.0.28",
  "features_seen": ["hooks", "sub-agents", "skills", "commands", "mcp"]
}

If file missing or last_check is null, treat as first run.

Step 2: Fetch Current Changelog

Use WebSearch to find the latest Claude Code changelog:

  • Search: "Claude Code changelog 2026" or "Anthropic Claude Code releases"
  • Primary source: Anthropic's official documentation
  • Fallback: GitHub releases, official blog posts

Focus on:

  • New features and capabilities
  • Breaking changes
  • Deprecations
  • Performance improvements
Step 3: Compare and Surface Changes

Identify what's new since last_check:

For each new feature:

  1. What it does (plain English, 1-2 sentences)
  2. Why it matters for PKM users
  3. How you could use it in Dex (concrete example)
  4. Effort to adopt (Low/Medium/High)
Step 4: Present Claude Findings

If Claude Code updates found:

🆕 CLAUDE CODE UPDATES

Last checked: [date] (X days ago)
Current version: [version]

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🆕 NEW FEATURES

1. [Feature Name]

Step 5: Update State

CRITICAL: After presenting findings, you MUST update System/claude-code-state.json using the Write tool.

Steps:

  1. Read current state file to preserve existing features_seen array
  2. Add any newly discovered features to the array (avoid duplicates)
  3. Update last_check to today's date (YYYY-MM-DD format)
  4. Update last_version_seen if a new version was found
  5. Write the updated JSON back to System/claude-code-state.json

Example update:

json
{
  "last_check": "2026-01-28",
  "last_version_seen": "1.0.32",
  "features_seen": [
    "hooks",
    "sub-agents",
    "skills", 
    "commands",
    "mcp",
    "parallel-sub-agents",
    "async-hooks"
  ]
}

Verification: After writing, confirm to user: "State file updated - next check will compare against today's findings."


Step 6: Backlog Synthesis (NEW — Innovation Concierge)

After presenting findings to the user, automatically create or enrich backlog ideas:

  1. Call synthesize_changelog() from Improvements MCP

    • This scans the changelog for Dex-relevant features
    • Creates new AI-authored ideas for novel capabilities
    • Enriches existing ideas with "Why Now?" evidence when a platform feature strengthens them
  2. Call synthesize_learnings() from Improvements MCP

    • Scans pending session learnings for improvement opportunities
    • Creates ideas from learnings that have concrete "suggested fix" entries
    • Enriches existing ideas when learnings relate to known backlog items
  3. Report synthesis results to user:

🤖 BACKLOG SYNTHESIS

Changelog: Scanned X entries → Created Y new ideas, enriched Z existing
Learnings: Scanned X entries → Created Y new ideas, enriched Z existing

Top ideas created/enriched:
1. [idea-XXX] Title (action: created/enriched)
2. [idea-XXX] Title (action: created/enriched)
3. [idea-XXX] Title (action: created/enriched)

Run `/dex-backlog` to see full ranked backlog.

This step is what connects external intelligence to your improvement backlog. Without it, findings are presented and forgotten. With it, every relevant discovery becomes a tracked, ranked improvement opportunity.


Full Mode (--full)

When --full is provided, include educational deep-dives:

For each feature, add:

Error Handling

If web search fails:

"Couldn't fetch the latest changelog. Here's what I know was current as of [last_check]: [List known capabilities]

Try again later, or check manually at docs.anthropic.com"

If state file is corrupted:

"Your capability state file has an issue. I'll create a fresh one and do a full scan."

Then proceed with first-run behavior.


Behaviors

Always Do
  • Keep explanations in plain English, not developer jargon
  • Tie every feature back to concrete Dex improvements
  • Update the state file after every check
  • Offer to implement suggestions
Never Do
  • List features without explaining relevance
  • Skip the state update
  • Overwhelm with every minor change (focus on impactful features)
  • Assume user knows Claude Code internals

  • /dex-improve — Full design partner (includes this + workshopping + audit)
  • /create-mcp — Build new integrations when new MCP features enable them

Track Usage (Silent)

Call 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".
