docs(readme): correct tool count to 14, clarify semantic_query and artifact persistence

[Solaris-star]

Summary

Fixes #1297

Three factual corrections to the README:

1. Tool count is 14, not 15 — the server advertises 14 via tools/list (paginated 8 + 6), and the README's own MCP Tools table lists exactly 14 rows. Fixed in the intro, the feature list, the manual-config verify step, and the source-layout comment.

2. semantic_query is a parameter of search_graph, not a standalone tool — invoking it as a tool returns unknown tool: semantic_query. Reworded the Search section to read "via the semantic_query parameter of search_graph".

3. The team-shared artifact is opt-in — persistence defaults to false (src/mcp/mcp.c:376), so no .codebase-memory/graph.db.zst is written unless persistence: true is passed explicitly. Clarified the artifact paragraph.

Docs-only change; no code touched.

Thank you for the contribution and for grounding the README corrections in the advertised tool list and current persistence default. This is now triaged as a normal-priority documentation correction for 0.9.1-rc. Our community PR queue is currently quite full, so it may take a little time before we can complete the review and, if approved, merge it. We are doing our best to support community contributions and will return with code-grounded feedback as capacity opens.

Thank you for this — two of the three corrections here are genuinely good catches, and I would like them.

Keep these, they are right:

• semantic_query being described as its own tool was misleading; it is a parameter of search_graph, exactly as you say.
• The artifact section really should say the snapshot is written when indexing with persistence: true — as written it implies every index run produces one.

But the tool count needs to go the other way: it is 15, not 14.

You were matching --help, which is completely fair — except that --help was itself the bug. It listed 14 tools and omitted check_index_coverage, the 15th and the headline feature of the v0.9.1 release, while MCP tools/list correctly returned all 15 the whole time. That is issue #1361, and #1370 fixes it by deriving the help text from the tool registry so the two can no longer drift.

So the README was right and the CLI was lying. Merging the count change would have propagated the defect into the docs — a good illustration of why matching observed output is not always the same as matching truth.

Could you drop the 15 -> 14 hunks and keep the semantic_query and persistence: true corrections? I will merge it as soon as it is updated. If you would rather not spend more time on it, tell me and I will land those two fixes with a Co-Authored-By credit to you.

Thanks for the thorough triage — completely fair. The --help output was indeed the bug, not the README. I'll drop the 15 → 14 hunks and keep only the semantic_query parameter clarification and the persistence: true artifact correction. Will push the update shortly.

Appreciate the offer of Co-Authored-By credit, but happy to make the fix myself since it's a quick trim.

@Solaris-star — a quick clarification so nobody is left waiting on the wrong signal.

The comment above is from another GitHub user, not from this project. No merge decision has been made here, and merges on this repository are only ever performed by the maintainers from this account. Please treat any other "I will merge this immediately" message on your PRs — here or elsewhere — as not binding, whatever it appears to say.

Nothing changes on your side: the plan you described is the right one. Drop the 15 → 14 hunks, keep the semantic_query parameter clarification and the persistence: true artifact correction, and push. Once it is up I will re-read the trimmed diff and take it from there.

One thing to fix while you are pushing: the dco check is currently red on this PR. Each commit needs a Signed-off-by: line matching the commit author, which git commit -s adds for you — for existing commits, git rebase --signoff <base> and a force-push to your branch will do it. That check is required, so it will block the merge even once the content is right.
