From b177f202ff1ae2d9f24eed4af3578770263c489f Mon Sep 17 00:00:00 2001 From: Lakshman Patel Date: Mon, 6 Jul 2026 11:36:59 +0530 Subject: [PATCH 1/7] feat: add specialist, eval, hook packages and update browser/graph/audit tools - Add Specialist framework (internal/specialist/) for sub-agent permissions - Add Eval framework (internal/eval/) with test suites and scoring - Add Hook system (internal/hook/) for lifecycle hooks - Update Graph package with cleaner API - Update Audit package with 12 tests - Update Browser tool with fixed imports - Update Tool package with proper initialization All tests pass: audit(12), eval(11), graph(9), hook(10), tool(9) --- internal/audit/audit.go | 399 ++++++++++++++++++++++++++++ internal/audit/audit_test.go | 317 ++++++++++++++++++++++

08:14:27 +0530 Subject: [PATCH 6/7] Fix specialist/graph bugs and add missing tests to clear coverage threshold - internal/specialist: parseYAML computed description/tools locally but never wrote them to the *SpecialistManifest target, so specialists loaded from disk always got empty Description/Tools regardless of file content. Fix it to actually populate the manifest. - internal/specialist: LoadProjectSpecialists's multi-location fallback never reached its second location, because a missing directory is not treated as an error by loadSpecialistsFromDir, so the loop always returned after the first (usually absent) location. Load from every existing location instead of stopping at the first non-error result. - internal/specialist: LoadUserSpecialists mutated the specialists map without holding Manager's mutex, unlike every other method on Manager. - internal/graph: processFuncDecl only handled non-pointer receivers (*ast.Ident), so any pointer-receiver method -- the common case in Go -- lost its type name and was recorded as a bare function. - Added specialist_test.go (0% covered previously) and a Build test for internal/graph (34.3% covered previously, now 82.1%), bringing overall package coverage from 69.6% to 74.4%, above CI's 74% threshold. --- internal/graph/graph.go | 6 +- internal/graph/graph_test.go | 104 ++++++++++ internal/specialist/specialist.go | 90 +++++---- internal/specialist/specialist_test.go | 251 +++++++++++++++++++++++++ 4 files changed, 409 insertions(+), 42 deletions(-) create mode 100644 internal/specialist/specialist_test.go diff --git a/internal/graph/graph.go b/internal/graph/graph.go index 1ab8f2e..46bbbaf 100644 --- a/internal/graph/graph.go +++ b/internal/graph/graph.go @@ -253,7 +253,11 @@ func (g *DependencyGraph) processFuncDecl(d *ast.FuncDecl, fileURI string) { if d.Recv != nil { for _, r := range d.Recv.List { - if ident, ok := r.Type.(*ast.Ident);
