v0.10.0: Agent-Evaluated, Agent-Improved

61 tools. 30 languages. 23 skills. This release was shaped by running the same 10-task evaluation across four AI models (Claude Opus 4.6, Cursor, GPT-5.5, Gemini 2.5 Pro) and fixing every friction point they found. Four models, four independent evaluations, all recommend agent-lsp.

get_editing_context (tool #61)

One call returns everything an agent needs before editing a file: symbols with signatures, callers partitioned by test vs non-test, callees, and imports. Supports ETag for conditional responses and includes token savings metadata.

/lsp-onboard skill (23rd skill)

First-session project onboarding. Explores the codebase via LSP: detects languages and build system, identifies entry points, maps package structure, finds hotspots, checks pre-existing diagnostics. Produces a structured project profile for the session.

Agent-evaluated quality improvements

Four AI models independently evaluated agent-lsp and surfaced friction points. All fixed:

• get_change_impact includes methods. Methods like (*Hub).SetSender were invisible because the receiver prefix ( failed the uppercase export check.
• get_change_impact per-symbol test callers. New affected_symbols field nests test and non-test callers under each symbol.
• position_pattern works without line/column. find_references and inspect_symbol now accept position_pattern alone.
• preview_edit net_delta ignores hints. Severity 3/4 diagnostics no longer count.
• destroy_session returns success for missing sessions. Returns "already_destroyed" instead of error.

Token savings metadata

list_symbols, get_symbol_source, and get_editing_context include _meta.token_savings showing tokens returned vs full file size.

ETag/conditional responses

File-scoped tools accept if_none_match. When the file hasn't changed, returns not_modified instead of recomputing.

Also

• safe_delete_symbol column resolution fix (unexported symbols now work)
• Flaky TestSubscribeHealth_Stop fixed
• Token savings wired into handlers
• 607 new test lines (coverage round 6)
