tools-script-scan — IMP FORGE

Shell/python script inventory + port-to-Rust pipeline. Finds every bash/python script in the tree, maps its consumers (hooks, CI, other scripts, docs), queues each as tracked port-to-Rust work (TECH-DEBT section + deduplicated GitHub issues), and can drive a first-draft conversion through the claude CLI into an isolated draft crate that must pass cargo test before a human wires it in.

What it is for

Shell/python script inventory + port-to-Rust pipeline.

The ecosystem rule is "all saved tooling is Rust, never bash/python" (fleet decision; see the tools family this crate lives in). Scripts still accumulate. This tool makes each one tracked work instead of quiet drift:

1. discover every .sh/.bash/.py (or bash/python shebang) file in the tree, 2. map consumers — the hooks, CI workflows, other scripts, Rust sources, and docs that invoke it — because a port is only done when every consumer is rewired, 3. queue the port as a TECH-DEBT entry + a deduplicated GitHub issue carrying the consumer checklist, 4. optionally draft the conversion through the claude CLI (--convert): the script, its consumers, and the process constraints go in; a candidate Rust crate comes out — written to an ISOLATED draft crate (own workspace, never auto-added to the main workspace) that must pass cargo test and human review before anything is wired.

Known-exempt: .claude/bootstrap.sh must stay bash — it runs before cargo exists on a fresh machine. docs/proposals/ scripts are illustrative spec artifacts, not tooling. Git hooks port behind a 2-line exec shim (git executes the hook file directly).

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

`crate root`

Item	What it is
`pub enum Lang`	Script language.
`Lang :: fn label(& self) -> & 'static str`	—
`pub enum Class`	Where a script is referenced from — drives porting priority.
`Class :: fn label(& self) -> & 'static str`	—
`pub struct Consumer`	One consumer reference site.
`pub struct Script`	One discovered script.
`fn is_ported_shim(src : & str) -> bool`	A ported exec shim: a tiny script whose only command execs the Rust replacement
`fn detect_lang(path : & Path, first_line : & str) -> Option <Lang>`	Detect a script by extension or shebang.
`fn classify(script_rel : & str, consumers : & Consumer) -> Class`	Classify from the consumer set + the script's own location.
`fn scan(repo_root : & Path) -> Result <Vec <Script>>`	Discover every script under `repo_root` and map its consumers.
`fn issue_title(script_path : & str) -> String`	Stable, deduplicatable issue title for a script's port.
`fn issue_body(s : & Script) -> String`	Issue body: the port plan per our process, with the consumer checklist.
`pub const DEBT_BEGIN: & str`	—
`pub const DEBT_END: & str`	—
`fn render_debt_section(scripts : & Script) -> String`	Render the managed TECH-DEBT.md section.
`fn splice_debt(existing : & str, section : & str) -> String`	Splice the managed section into TECH-DEBT.md content.
`pub const MAX_SCRIPT_BYTES: usize`	Cap on script source embedded in a conversion prompt.
`pub struct ConvertPlan`	The JSON contract the model must return for `--convert`.
`pub struct PlanFile`	—
`pub struct Rewire`	—
`fn build_convert_prompt(script : & Script, source : & str) -> String`	Build the headless conversion prompt: script + consumers + the process constraints the generated code must satisfy.
`fn parse_convert_response(raw : & str) -> Result <ConvertPlan>`	Parse + validate the model's response
`fn write_draft(draft_root : & Path, plan : & ConvertPlan) -> Result <PathBuf>`	Write the plan into an ISOLATED draft crate under `draft_root`

No pub use re-exports: every item above is declared in this crate.

Boundary

Depends on no other workspace tier.

Shares tier tools with 84 other crates: tools-advisory-reach, tools-archive-guard, tools-artifact-scaffold, tools-ask-ai-core, tools-ask-ais, tools-ask-gemini, tools-book, tools-book-report, … (84 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._
