Skills
Free, open-source skills that extend Claude Code and Codex with capabilities drawn from real delivery work - each installs from the DBHQ marketplace with a single command, no sign-up.
/plugin marketplace add dbhq-uk/marketplaceMicrosoft 365 mail and calendar, from the terminal
Read, search, send and manage mail and calendars without leaving your agent. It also turns a PST archive into searchable markdown with a SHA256 chain of custody over every message, which is the half that came out of a real client handover.
Your boards, run from your agent
Boards, lists and cards end to end, plus the moves that save real time: an instant board digest, a due-date radar for what is slipping, and smart card sorting. Four skills in one install.
Research that settles a decision, and says when it cannot
A source is judged by the claim it backs, so a vendor's pricing page proves a price but not whether the product is good. Sources only corroborate when they could have disagreed. Every finding states how well it is supported, and a run that settles nothing says so.
Checks whether your repository still agrees with itself
It maps your docs and code and reports where they have drifted apart: dead links, moved anchors, orphaned files, documentation describing behaviour the code no longer has. The exact checks need no model and no network and run in seconds, which is what makes them safe to fail a build on. It never edits without asking.
Strips AI tells from prose and puts a voice back
In British English, and it does the harder half. Subtraction alone leaves text that still reads as machine-made, just blandly rather than floridly. Meaning is a veto: every figure, name and claim survives. Writing that already reads as human comes back untouched.
Compiler-exact code search for .NET
Where a symbol is defined, every reference, who calls it, and what a change breaks, answered from Roslyn in about a second. So it is what the compiler believes rather than what a regex matched, and Razor views and Blazor components are indexed rather than skipped. If a project fails to load, it says so.
What is a skill?
A package of instructions and tooling that teaches a coding agent - Claude Code or Codex - to do something it could not do before. Not a chatbot wrapper: the agent gains a real capability, calls real APIs, and works in your terminal alongside your code. Each of these started as something I needed on an engagement, got hardened until it was reliable enough to depend on, and then got published. That is the whole selection rule - if I do not use it myself, it is not here.
Why are they free?
Because they are the most honest demonstration I have. You can read every line, install it in one command and judge the engineering yourself, before you ever talk to me. That is a stronger argument than a case study and a far stronger one than a slide - and it is the same judgment you would be buying on an engagement, just given away in a smaller box.
Fifteen minutes will tell you if this fits
Bring the problem - the stalled pilot, the systems that don't talk, the manual process eating your team. You will get a straight answer on whether it is sprint-shaped, what it would cost, and when it could be running.
