The analytics export. On desktop: x.com/i/account_analytics, then Export. It is a Premium feature. One row per post: impressions plus the engagement counts (likes, replies, reposts, bookmarks, shares, new follows, profile visits). X does not document the column names and they have changed before, so audit.py matches them loosely; the older analytics.twitter.com export parses too.
A sheet by hand with post text, impressions, and whatever counts the user can see. Twenty rows is enough for a first pass.
Screenshots of the posts with their numbers. Transcribe into a CSV.

Also read ~/.claude/x/log.md if it exists: it records which hook formula each post used.

What it measures, and why not impressions

Impressions are mostly a function of how many people already follow the user. audit.py ranks on things that are not:

metric	what it tells you
Engagement rate	whether the post earned the reach it got
Replies per 1k impressions	whether it started a conversation. X's ranker weighs replies far above likes
Shares per 1k (reposts + shares)	whether it travelled. Shares by DM or copied link are among the highest-weighted actions X publishes
Bookmarks per 1k	whether someone plans to use it
Follows per 1k	whether it made anyone want more of the user

Posts under a noise floor of impressions are left out of the ranking, and the user's replies on other people's posts (rows starting with @) are counted and set aside so a good week of replying does not drown the posts.

Then find the pattern

audit.py groups the posts by hook formula (classified with ../x-post/hooks.json), by length, and by format (text only vs with a link or media), and reports every group whose engagement rate is 1.4x above or below everything else, with its n and a confidence word. It checks day of week last, and only mentions it when nothing else separates. It is almost never the cause, and it is where people want it to be.

Add what the script cannot see, reading the top 5 and bottom 5 side by side:

Topic. Which of the user's themes are in the top five?
Whether the user replied in the first hour.
Whether the post was the user looking good or the user looking bad.

The link question, answered with their own data. X says it stopped down-ranking link posts over a year ago. An independent analysis in January 2026 still measured fewer views on them. If the format finding shows link posts well below the rest with n of 5 or more, that is the answer for this account, whatever anyone says. If it shows nothing, links are fine here.

State every finding as a claim with the evidence attached, and say how confident it is. With 30 posts a pattern can show. With 8, say that instead of inventing one.

Output

AUDIT  ·  38 posts  ·  Jul 01 - Aug 28  ·  15 replies set aside

TOP BY ENGAGEMENT RATE
    5.8%    8.6 rep/1k    8.6 shr/1k     5,705 imp  "$4,000 is what one bad hire cost me."
    ...

WHAT THE DATA SAYS
  1. format = text only: 2.7% vs 0.8% for everything else (3.3x, above). n=26, solid.
  2. hook formula = Cost Confession: 3.9% vs 1.9% (2.0x, above). n=4, weak.
  Day of week shows nothing. Stop optimising it.

STOP:     link-first posts. Put the link in a reply for the next ten and re-run.
DO MORE:  the posts where you paid a cost, with the number in line 1.

Then hand the conclusions to /x-plan, so next week is built on the user's own evidence instead of on defaults.
