Route A โ€” install the skill

A one-time install. After that, say "audit my context" in any Cowork project and it runs โ€” and unlike the prompt, the skill can go and look at your actual work first.

Recommended ยท For Cowork

The Context Audit skill

It reads your context files, optionally gathers evidence from your real work, then names the gaps, scores each file out of 5, and writes the fixes.

What the skill adds

An audit based on evidence, not self-report

A prompt can only grade what your files say about themselves. The skill can ask permission to look at your real work first โ€” and then the audit gets much sharper, because it can catch the gap between what you wrote down and what you actually do.

It might come back with: "your priorities list says brand campaigns, but everything in this folder for two months has been localisation" โ€” or "your voice file says you avoid jargon, but here are three lines where you used it." That's the finding you can't get from a prompt.

How it behaves
  • It asks first, and only looks at the sources you name โ€” files only is a valid answer.
  • Read-only. It never writes, sends or changes anything in a connected tool.
  • Your material only โ€” it won't build a picture of colleagues or quote other people.
  • It skips anything sensitive: salary, HR, health, legal, personal finance, credentials.
  • It tells you which sources it actually used, so you can check the basis of the audit.

Route B โ€” or just paste the prompt

No install, works anywhere. This version audits your files only โ€” it won't go looking at your work. Open the project, paste, send.

Any Claude ยท reads whatever files are there
Audit the context you have about me. Be blunt โ€” I want the gaps, not reassurance.

STEP 1 โ€” Read every file in this project folder, especially about-me.md, personal-voice.md and working-style.md, plus any global instructions you have.

STEP 2 โ€” Tell me, in plain language, what you actually know about me right now: my role, who I work for, what I'm prioritising, how I sound, and how I want to be worked with. Two short paragraphs. If any of it is inferred rather than written down, say which.

STEP 3 โ€” Now the useful part. Name the gaps, specifically. For each one: what's missing, which file it belongs in, and why it would change your output. Cover at least:
- Facts about my work you'd have to guess at
- Anything that reads like it's out of date
- Voice: could you write a paragraph that I'd believe I wrote? What's missing to get there โ€” more samples, sharper rules, words to avoid?
- Working style: is there anything you still have to ask me every time?
- Contradictions between files, or between the files and how I've actually behaved in this project

STEP 4 โ€” Score each of the three files out of 5 for how usable it is, with one sentence saying why. Don't be generous.

STEP 5 โ€” Give me the fixes as ready-to-paste text. For each gap, write the actual lines to add and tell me which file to put them in. Don't describe the change โ€” write it.

STEP 6 โ€” Then ask me the three questions that would close the biggest gaps, one at a time. When I answer, update the files directly.

Be specific and honest. If a file is thin, say so plainly โ€” a vague audit is worse than none.
What you get back
What it knowsA plain-language summary of you as Claude currently understands you โ€” and the parts it's been quietly guessing.
The gaps, namedLine by line, with the file each one belongs in and why it matters to the output.
A score per fileOut of 5, with a reason. Useful for spotting which file you've been neglecting.
Ready-to-paste fixesThe actual lines to add, not advice about adding them.
Three questionsAnswer them and it updates the files for you, on the spot.
The voice check is the one to pay attention to. Ask it directly: could you write a paragraph I'd believe I wrote? If the answer is no, the fix is almost always the same โ€” add another real writing sample. Two samples is the minimum; three is noticeably better.
Works in Claude.ai too, with one change. No project folder there, so paste your three files into the chat first, then run the prompt. You'll get the same audit โ€” you just have to apply the fixes by hand afterwards.
The Starter Kit skill can do this too. If you haven't built your files yet, the interviewer will offer to look at your real work first and draft most of them from it โ€” so you never have to go hunting for writing samples. Same permission model as here.

Why bother

Setting up context is a one-off task that everyone does once and never revisits. But the files are the thing doing the work โ€” the model didn't get better at sounding like you, your files did. Auditing them every month or two is the cheapest quality improvement available to you, and it takes about ten minutes.

Haven't built the files yet? Start with the Cowork Starter Kit โ€” a skill interviews you and writes all three.
