Three concrete changes addressing the "analyst Claude misuses the CLI"
class of bugs (image.png table — issues #3, #5, plus the recurrent
"how big is this table" guesswork):
1. config/claude_md_template.txt — the template agnes init writes to
<workspace>/CLAUDE.md. Surfaces every catalog-row field with a why,
adds a query_mode-based decision tree, explicit --estimate scoping
(snapshot create ONLY — was the #1 first-try error), an agnes fetch
→ agnes snapshot create rename note, and a 6-row failure-mode table
that maps each common error wording to its right next step.
2. app/api/v2_catalog.py — populate rough_size_hint for local +
materialized rows from the on-disk parquet size, bucketed
small/medium/large/very_large. Was hardcoded null with a TODO; AI
couldn't tell "is this 6.8 GB" without a failed --remote round-trip.
3. cli/update_check.py — the [update] banner survived the da→agnes
rename and printed "[update] da X is out of date" on every command,
training analysts to associate the binary with the old name.
Verified by rendering the template against representative contexts
(33/33 tests pass) and running every use case from the original
screenshot through the real CLI against a dev VM.
