 It is **local-first** by default (no network required after first run, no prompts leave your machine), **safe by construction** (risk-classified, deterministic guards, audit log), and **composable** (`i "ping google's dns" | i "if reachable exit 0 else exit 1"`).
 
+That composability applies to subcommands that consume natural language too: `i report "first problem" < extra-notes.txt` appends the piped text after the command-line text before proposing issues.
+
 > **Status: pre-alpha.** The binary builds and the mock backend round-trips the full prompt → propose → confirm → run loop, but the local model runtime, daemon, and self-update flows are still being wired up. See [`INTENT.md`](./INTENT.md) for the full project charter, [`docs/SPEC.md`](./docs/SPEC.md) for the implementation contract, and [open issues](https://github.com/CoreyRDean/intent/issues) for the roadmap.

 Converts natural language into one or more GitHub issues against `CoreyRDean/intent`:
 
+`i report` accepts natural language from argv, stdin, or both. When both are present, argv text comes first and stdin is appended after it.

 1. Parse the user's input. The model returns an array of `{title, body, labels, kind}` proposals.
 2. For each proposal, query GitHub Search (`is:issue repo:CoreyRDean/intent <terms>`) for the top 5 candidates.
 3. For each candidate, compute a similarity score (token-set ratio + embedding-similarity if a small embedding model is available; otherwise just token-set ratio). If ≥0.85, treat as duplicate.
