sniff

sc-rust Sniff

Rust stack detector and pivot manifeste producer.

Available actions

#	Action	Role	Input
01	scan	Detect capabilities, emit pivot manifeste, map perf/data install targets	current project path
02	install-pivots	Install perf/data pivots to .claude/rules/07-quality/	scan pivot manifeste

Default flow

Sequential: scan → install-pivots.

Conceptual model

• A capability is something the app does: serve HTTP via Axum/Actix-web, query the database via SQLx or Diesel, etc.
• A pivot is the Rust knowledge for the chosen solution (e.g. Axum perf patterns, SQLx query conventions)
• Capability pivots live in the plugin (skills/sniff/references/capabilities/) — they are loaded at audit time by /sc-rust:audit, not installed to the project
• Perf pivots and data pivots are the exception: they ARE written to .claude/rules/07-quality/ because web-optimize and data-optimize read them from there

Transversal rules

• If Cargo.toml is absent and no workspace is found, abort with an explicit message.
• Never install a capability pivot to .claude/rules/ — those are loaded on demand at audit time.
• Both axum and actix-web map to the same perf pivot (perf/axum.md). Install it only once.
• Never install a data pivot for a crate not detected in Cargo.toml.
• Compare installed pivot content against the plugin reference before updating — skip files already identical.
• Report every file written, updated, or skipped.
• Report gaps: capabilities detected but no matching plugin pivot exists.
