Summary

Exclude development-only dependencies from the default production dependency graph, package totals, duplicate analysis, and unused-dependency findings. Keep build dependencies included because production compilation requires them, and preserve dependencies.include_dev = true as an explicit opt-in.

Related issue

None.

API or behavior changes

The default value of DependencyConfig::include_dev changes from true to false. This changes default report contents but does not remove or rename any public API.

Validation

Commands actually run, with their outcome:

  • cargo fmt --all -- --check
  • cargo clippy --all-targets --all-features -- -D warnings
  • cargo build --all-targets --all-features
  • cargo test --all-features
  • cargo run -p tinyanalyzer -- . --output summary

Tests

Extended the real Cargo workspace integration fixture to cover a dev-only package and a build dependency. The regression proves dev edges, dev-only packages, and dev-only unused findings are excluded by default, restored by opt-in, and build dependencies remain included.

Documentation

Updated the root README, core README, configuration docs, and accepted analysis contract.

Checklist

  • The change is focused on one logical change
  • No new #[allow(...)], #[ignore], or relaxed lints
  • No secrets, tokens, or .env contents in the diff or the description

Summary by CodeRabbit

  • New Features
    • Added an optional dependencies.include_dev setting to include development dependencies in analysis.

  • Bug Fixes
    • Improved dependency reports by excluding unrelated and development-only packages from the default graph.

📝 Walkthrough

Walkthrough

The dependency graph now excludes development dependencies by default while retaining build dependencies. The include_dev configuration opts into development dependencies. Documentation, defaults tests, graph filtering, and public API fixtures reflect the updated behavior.

Changes

Dependency graph defaults

Layer / File(s) Summary
Configuration contract and defaults
crates/tinyanalyzer-core/src/config/types.rs, crates/tinyanalyzer-core/src/config/test.rs, README.md, crates/tinyanalyzer-core/README.md, docs/specs/analysis-contract.md
dependencies.include_dev now defaults to false. Documentation states that development dependencies are excluded by default, while build dependencies remain included.
Resolved graph filtering
crates/tinyanalyzer-core/src/deps/mod.rs
analyze uses resolved_metadata and reports only workspace members and packages reachable from them.
Fixture coverage for dev and build dependencies
crates/tinyanalyzer-core/tests/public_api.rs
The fixture adds development and build tools. Tests verify default exclusion, build-edge retention, and opt-in development analysis.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 9ff6b

The new default can produce dependency reports with edges pointing to excluded development-only packages, making the report internally inconsistent; this should be fixed before merge. The README opt-in example also needs a minor correction.

Poem

I’m a rabbit with a tidy graph,
Dev hops out unless invited back.
Build tools stay upon the trail,
Cargo’s map now tells the tale.
Config seeds the path just right.

P2 Badge Preserve production edge identities

When an optional dependency activated only by a development feature is also present in production through another package, both endpoints occur in package_ids, so this filter copies the development-activated metadata edge into the production graph. For example, if app normally depends on both engine and leaf, while its dev declaration enables an engine feature that adds optional engine -> leaf, the production resolution has no engine -> leaf edge but this code retains it, inflating engine's reach/transitive metrics and potentially reporting that optional declaration as unused production weight. Fresh evidence after the attempted fix is that resolved_edges now checks only endpoint membership, not whether the production tree contains the edge itself; retain production edge identities as well as package IDs.
