At a glance

Adopt one shared DexDiff methodology — reads a workflow description, adapts it to your role and vault, and walks you through setup.

  • Works in 7 steps: Introduce the Job → Discover Together → Customise → …
  • The user says adopt this workflow
  • SKILL.md covers What This Command Does, Arguments, The Onboarding Flow and Edge Cases, plus 2 more sections
  • Reaches heydex.ai and api.heydex.ai

What it does

Diff Adopt is an agent skill from davekilleen/Dex. Adopt one shared DexDiff methodology — reads a workflow description, adapts it to your role and vault, and walks you through setup. Use when the user says 'adopt this workflow', 'set me up like this doc'. Not for a full published profile by handle; use diff-adopt-profile.

Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Your AI Chief of Staff — a personal operating system starter kit that adapts to your role. No coding required.

When your agent uses it

  • The user says adopt this workflow
  • Set me up like this doc

Example prompts

  • “adopt this workflow”
  • “set me up like this doc”
  • “/diff-adopt”

Workflow steps

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

  1. Introduce the Job
  2. Discover Together
  3. Customise
  4. Preview and Explain
  5. Build
  6. Log the Adoption
  7. Walk Through First Use

What it can do on your machine

Read from SKILL.md and the folder at commit ab5d6ad. 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

    Hosts in commands or code, which the agent is likely to contact:

    • heydex.ai
    • api.heydex.ai

    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

Diff Adopt loads about 3.1k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 974 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~3.1k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 974 words (~3,126 tokens).

“In plain English: Someone figured out a great way to use Dex for a specific job — like prepping for meetings, reviewing deals, or building performance evidence. This command reads their methodology and walks you through setting up a similar…”
