Custom Claude Skills — Designed Around How Your Team Actually Works

Most Claude skills are built from a brief. Ours are built from two hours of sitting with the people doing the work. That's why they get used.

The problem with most AI skills

A generic AI consultancy gets a two-paragraph brief, writes a prompt, ships it in 48 hours. The skill works on the example the brief described. It fails on the 40 real cases the brief didn’t mention — the matter type the associate wasn’t thinking about, the legacy file format only three people still use, the approval loop nobody documented.

Adoption dies within a month. The team goes back to doing it manually. We do the opposite.

Our method — Observe, Co-design, Ship

1. Observe

We shadow the people who will use the skill for a half-day each. Not interview — shadow. We sit with 2–3 users per function, across seniority levels, and we take notes on every decision point, every system touched, every judgment call, every shortcut.

2. Co-design

We run a one-hour co-design session with the user and the Tinkso engineer who will build the skill — together. By the end of the session, the skill spec is theirs as much as ours.

3. Ship

We build and test against 5–10 real cases from the user’s actual work in the last 60 days. Not synthetic data, not the happy path — the ones that break.

Three skills we’ve shipped — and what we heard that wasn’t in the brief

Renewal Brief Generator (legal services)

Pulls contracts from SharePoint, extracts renewal terms, cross-references account owner in Salesforce, drafts outreach email.

What the brief said: “Automate the quarterly renewal outreach — it takes associates 6 hours.”

What we heard during shadow sessions: three of the six hours weren’t writing the outreach — they were finding the last outreach. We redesigned the skill to lead with a relevant-context pull, not a blank draft.

Outcome: 6 hours → 45 minutes.

Deal Prep Packet (B2B SaaS)

Pulls account history, support tickets, product usage, decision-maker LinkedIn into a one-page brief.

What the brief said: “Automate pre-call research — reps spend 20 min per call.”

What we heard: reps weren’t struggling with the research — they were struggling with which product usage metric mattered for which account type. We built branching logic that keyed off account type.

Outcome: 20 min per call → 75 seconds.

Variance Commentary (finance)

Runs month-end variance: actuals from NetSuite, compares to budget, drafts board-ready commentary.

What the brief said: “Automate variance commentary — takes the analyst a full day.”

What we heard: the commentary wasn’t the slow part. The slow part was explaining variances the analyst didn’t understand until she’d called three operators. We added a ranked “chase list” with the operator’s name pre-attached.

Outcome: full day → 90 minutes.

Why work-first design wins on adoption

FAQ

Half a day per user, 2–3 users per function. For most engagements, discovery runs 3–5 days total across all functions.
