With skillzero, you can manage the skills via CLI. It splits them in 3 categories: - hidden skills (entirely removed from context) → they now behave like /-commands - collection skills (bundled into one skill, so the agent sees only one name + description) → agent can still invoke these when it thinks it should use them - regular skills (untouched by skillzero)

You can install it via `npx skillzero` (or `pnpx` or whatever you prefer).

[1]: Actually Claude Code & Codex have an optimization, if the name+desc's exceed 1%/2% of the context window, both will omit some skills entirely.

Happy to hear any feedback!

``` - For planning, prefer using morph-mcp `codebase_search` - subagent that takes in a search string and tries to find relevant context. Best practice is to use it at the beginning of codebase explorations to fast track finding relevant files/lines. Do not use it to pin point keywords, but use it for broader semantic queries. "Find the XYZ flow", "How does XYZ work", "Where is XYZ handled?", "Where is coming from?" ```

(see also https://news.ycombinator.com/item?id=48205911; having higher quality results at the beginning of a thread seem to improve the output vs. having faster search later on).

> The clearest result was that faster search alone only modestly helps, while better-ranked results improve first-query retrieval and help agents find the right code sooner.

Their tool "pgr" is a research preview only, so it'd be interesting to see semble vs pgr.

I'm also collecting other tools that are similar, most notably is probably Morph's WarpGrep (has a free tier too). Apart from that, there is codemogger (https://github.com/glommer/codemogger), cs (the author also commented in this HN post).

In the similar area, but not fully related, the author of fff is also pretty involved in any thread that goes into that direction (see e.g. https://x.com/neogoose_btw/status/2052161471296225710). Similar to colGREP is also mgrep (by mixedbread) and osgrep (but they seem to predate colGREP). I also found codedb on X (https://codegraff.com/blog/codedb-code-intelligence), the post reads well, but haven't tried.

The only bench I'm aware of was presented in November 2023: https://x.com/boshen_c/status/1719596594985681275?t=x8FaB9Aw..., where esbuild was faster.
