/supergraph:scan

Load verified, project-scoped graph context once. Follow the shared references/codebase-memory-contract.md.

Announce: "📡 /supergraph:scan — loading project context..."

1. Detect project and branch

Use git branch --show-current, resolve the repository to an absolute path, and run bin/detect-project.sh when present. Otherwise detect commands from:

File	Type	Test	Lint	Format	Build
package.json	node	npm test --	npx eslint .	npx prettier --write .	npm run build
Cargo.toml	rust	cargo test	cargo clippy	cargo fmt	cargo build
pyproject.toml	python	pytest	ruff check .	ruff format .	python -m build
go.mod	go	go test ./...	golangci-lint run	gofmt -w .	go build ./...
pubspec.yaml	flutter	flutter test	flutter analyze	dart format .	flutter build

Ask when none match; never guess commands. Derive one stable CBM_PROJECT from the repository root name and retain it across branches. Default CBM_INDEX_MODE=moderate.

2. Verify provider and freshness

1. Call list_projects and find CBM_PROJECT.
2. If found, call index_status(project=CBM_PROJECT).
3. Treat missing project, changed branch, stale state, tool error, failed state, or status: "degraded" as requiring a new index.
4. TTL reuse (10m): If index_status returns status: "ready" and BRANCH matches .supergraph-env:BRANCH and now - CBM_INDEXED_AT < 600s and head_sha unchanged, reuse index — skip index_repository. Otherwise proceed to step 5. TTL check requires healthy index_status; never cache degraded/stale/error. On cache hit, still re-run index_status once to confirm liveness before get_graph_schema.
5. Call index_repository(repo_path=<absolute repo path>, name=CBM_PROJECT, mode=CBM_INDEX_MODE) when required (cache miss or stale/degraded). Require status: "indexed".
6. Re-run index_status; never claim reuse without a healthy response.
7. Call get_graph_schema(project=CBM_PROJECT) and get_architecture(project=CBM_PROJECT, aspects=["overview","layers","boundaries","clusters","hotspots"]) in parallel after verified index_status.
8. On cache hit, get_graph_schema and get_architecture may run in parallel immediately after TTL-passed index_status.

On any mandatory provider/index/schema error: STOP, show the exact error and the recovery command (codebase-memory-mcp cli index_repository --repo-path <absolute> --name <project> --mode moderate). Do not write freshness state.

3. Reverify Serena

Always call Serena initial instructions and activate project when available, then load a top-level symbols overview. Set SERENA_ACTIVE=true only after success; otherwise set it false and report Serena unavailable.

4. Write .supergraph-env

Only after healthy index_status, schema, and architecture responses:

PROJECT_TYPE=...
TEST_CMD=...
LINT_CMD=...
FORMAT_CMD=...
BUILD_CMD=...
BRANCH=...
GRAPH_PROVIDER=codebase-memory-mcp
CBM_PROJECT=...
CBM_INDEX_MODE=moderate
CBM_INDEXED_AT=YYYY-MM-DDTHH:MM:SS
SERENA_ACTIVE=true|false
SCAN_TIMESTAMP=YYYY-MM-DDTHH:MM:SS

Branch-matched TTL reuse still requires index_status and Serena revalidation; TTL only skips index_repository, never skips index_status or schema checks. Serena revalidation is guarded by SERENA_ACTIVE — skip initial_instructions if .supergraph-env:SERENA_ACTIVE=true and scan ran <10m ago.

5. Report

Report project/type/commands, provider/project/index status, architecture counts available from the response, Serena status, and whether scan was fresh or reused.

Rules

• Never record false freshness after errors or degraded state.
• All graph calls include project=CBM_PROJECT where supported.
• Respect pagination and failure semantics in the shared contract.
• For trivial ≤2 files / <20 lines, graph discovery may stop after verified status (no hubs/bridges needed).
