Discover reports many missed savings

Apologies if this is a beginners' mistake but I found no documentation about it...

When I run rtk discover it shows me many missed savings, even from "Commands RTK already handles". What does that mean exactly? If these commands are handled, then we do I not get the savings for these commands? Do I need to somehow update my configuration to do so? Is rtk init -g insufficient?

I also asked claude about this and it told me it might have something to do with its system prompt. Can anybody here tell me how to increase my savings?

CLAUDE output:

Still 290 missed commands in just the last day, even with the hook active. The hook is registered and working — so why isn't it catching these?

The answer: those aren't Bash tool calls from me. rtk discover scans all Claude Code sessions for this project, which includes commands from Glob, Grep, Read tools that internally invoke find, grep, cat — as well as commands from other Claude Code sessions or agents that may not go through the hook. The find (69) and grep -r (50) and cat (7) are likely from the dedicated tools (Glob, Grep, Read) which execute internally without going through the Bash tool hook.

The git diff (78) and gh api (42) are the real missed savings — those are genuine Bash calls. The git diff ones may come from the automatic git diff that runs during commit workflows, which is part of my system instructions (not prefixed with rtk). And gh api calls I should be prefixing with rtk but haven't consistently.

Summary: The hook is correctly installed and working. The bulk of "missed" commands fall into two buckets:

1. Tool internals (find, grep, cat, ls) — these are from Glob/Grep/Read tools, not Bash calls the hook can intercept
2. Unprefixed Bash calls (git diff, gh api) — genuine misses, mostly from system-prompted workflows (commit/PR creation) where the instructions say to run git diff directly
