Part of the Weavatrix ecosystem. This repository preserves the explicit JavaScript refactoring line.
This is the JavaScript refactoring engine of Weavatrix, continued as
weavatrix-refactor-js. The
package ships the native Rust MCP host built on
weavatrix-rust and the
weavatrix-edit/weavatrix-refactor-plan/weavatrix-worktreecrates.
This package continues that version line:
weavatrix-refactor@0.1.5was the
last JavaScript release under the old name, and
weavatrix-refactor-js@0.1.6
picks up from it. Install
weavatrix-refactor-js, or pin
weavatrix-refactor@0.1.5, to stay on the JavaScript implementation.
Evidence-backed, transactional refactoring for coding agents.
weavatrix-refactor-js is the write-capable member of the JavaScript family. It combines the complete read-only weavatrix-js code-intelligence MCP with 11 refactoring tools that can prove a change, preview it against the current working tree, apply it atomically, refresh the graph, and roll it back.
Engine boundary: this package hosts the
weavatrix-jsengine. It does not
use the native
weavatrix-rustengine, and installing both packages does not
silently upgrade this one's analysis layer. Its state lives in
~/.weavatrix-refactor-js, kept separate from the Rust host's so the two
never share a lock, a token store, or a rollback journal.
It is substantially more than a rename wrapper:
before text, provenance, uncertainty, and graph revision in every applyable plan;The MIT weavatrix-js core is physically read-only: its published artifact has no repository source-write path. This package is the explicit write boundary. Installing it and selecting its refactor profile makes the edit capability visible; without this package, the server cannot modify source.
The split is a safety property, not packaging cosmetics:
weavatrix-js core weavatrix-refactor-js repository
read-only evidence -> plan + preview + confirmation -> atomic write graph / LSP / audit hashes / provenance / rollback refreshed graph
The implementation is a ports-and-adapters system with one-way boundaries:
edit-plan model <- filesystem / lock / token adapters
^ ^ | | plan engines -> preview / apply / rollback workflows -> MCP adapter
weavatrix.edit-plan.v1 envelope and applies byte-exact edits as pure string transformations.weavatrix-js catalog and exposes one stdio server.The checked-in strict architecture contract enforces zero runtime cycles, files no longer than 300 lines, and functions no longer than 100 lines. It has no exceptions or ratchet baseline.
An ordinary editor rename answers: "Which text edits should I make now?" Weavatrix Refactor also answers:
| Question | Evidence returned |
|---|---|
| Is this the exact symbol? | Stable graph symbol id plus parser/LSP selection range |
| Which references are proven? | Per-edit provenance: EXACT_LSP, RESOLVED, EXTRACTED, or LEXICAL_EXACT |
| What was not proven? | Explicit uncertainReferences, notModified, warnings, and PARTIAL completeness |
| Which files were even looked at? | The rename session seeds every graph-declared reference plus every indexed file whose text contains the identifier; anything it could not open is named and forces PARTIAL |
| Did the tree change after preview? | File sha256 plus exact before text rechecked under the write lock |
| Can several renames partially succeed? | No. Related renames are conflict-checked and applied as one transaction |
| What happens after a disk/write failure? | Already-written files are restored; a durable rollback bundle remains |
| Will a move worsen architecture? | Projected runtime cycles, boundary violations, improvements, and blast radius |
| Did the refactor preserve behavior-shaped structure? | Refreshed graph plus verified_change caller/import/reference conservation |
The system fails closed when proof is insufficient. It never upgrades an INFERRED edge into an applyable edit and never hides an ambiguous reference.
rename_symbol and rename_related_symbols are complete operations, not PLANNED-only helpers. Each method owns both phases.
Call the rename method normally:
{
"symbol": "src/users.ts#getUser@12", "new_name": "getCustomer" }
The method computes the rename, validates every plan file against the working tree, and returns PREVIEW_OK with a short-lived confirmToken. Preview never writes source and does not require the environment write gate.
Repeat the same operation inputs and add the confirmation:
{
"symbol": "src/users.ts#getUser@12", "new_name": "getCustomer", "mode": "apply", "confirm_token": " " }
The tool recomputes the deterministic plan, verifies that the token belongs to that plan and repository, takes the repository lock, rechecks hashes and before text, writes a rollback bundle, and applies every edit bottom-up.
The same contract applies to a coordinated set:
{
"renames": [ {"symbol": "src/api.ts#getUser@8", "new_name": "getCustomer"}, {"symbol": "src/api.ts#getOrder@20", "new_name": "getPurchase"} ] }
rename_related_symbols detects overlapping edits, chains, swaps, shadowing risk, and per-sub-rename failure before it issues a token. Apply is one atomic multi-file operation.
| Tool | What it actually does |
|---|---|
rename_symbol | Cross-language preview/confirm/apply rename. Dispatches to exact JS/TS LSP, SQL schema, or strict graph+lexical backends; returns honest backend completeness and every uncovered reference. |
rename_related_symbols | Coordinates up to 50 JS/TS symbol renames in one shared language-server session and one atomic edit plan. Detects conflicts, chains, swaps, snapshot drift, and any failed sub-rename before writing. |
apply_edit_plan | Generic two-phase executor for weavatrix.edit-plan.v1 envelopes from the other tools or weavatrix-online. Preview issues a plan-bound token; apply writes atomically with rollback. |
rollback_last_apply | Restores the latest pre-apply bundle. Refuses if post-apply files drifted; retries converge after an incomplete restore. |
| Tool | What it actually does |
|---|---|
change_signature | Adds or removes a JS/TS function or method parameter. Performs byte-exact declaration and call-argument surgery; spread calls and value-requiring additions remain explicit uncertainty. |
edit_symbol | Uses the indexed parser range for replace_symbol_body, insert_before_symbol, or insert_after_symbol. JS/TS output is parse-gated; line endings and UTF-16 coordinates are preserved. |
bulk_replace | Two-stage, occurrence-selective replacement over indexed files. First returns stable occurrence ids; the second call accepts chosen ids or an exact expected count and emits a hash-bound plan. Literal mode is the default; regex replacements use real capture expansion. |
organize_imports | Removes only provably unused named JS/TS imports. Default and namespace imports stay uncertain; side-effect imports are untouched; sorting is deliberately left to the formatter. |
These plans are applied with apply_edit_plan, using the same preview, token, atomic-write, and rollback protocol as rename.
| Tool | What it actually does |
|---|---|
move_file | Builds a JS/TS relocate review: rewrites importer specifiers and the moved file's own relative imports, then projects architecture effects. File renaming itself remains an explicit editor/agent action, so this is intentionally not an apply envelope. |
move_symbol | Projects a declaration move without inventing byte edits. Reports introduced/removed runtime cycles, target-file dependencies, architecture violations or improvements, and blast radius. |
delete_readiness | Returns safe: true, false, or UNPROVEN with known references, dynamic/reflection risks, confidence, and the declaration span. Exported symbols are capped at UNPROVEN; deletion is never automated. |
| Surface | Backend | Applyable provenance | Completeness contract |
|---|---|---|---|
| JavaScript / TypeScript rename | Bundled TypeScript language server | EXACT_LSP | COMPLETE only when every file that could mention the symbol was opened in the rename session and proven; any candidate left out forces PARTIAL |
| SQL table rename | Schema-aware SQL scanner across SQL and host files | EXTRACTED / LEXICAL_EXACT | Reports every skipped or ambiguous reference |
| SQL field rename | Definition-safe SQL backend | Proven definition edits only | Usages remain UNPROVEN rather than guessed |
| Python / Rust / Go / Java / C# / Solidity rename | Indexed graph references plus exact lexical location on the recorded line | EXTRACTED / LEXICAL_EXACT | Always PARTIAL; ambiguous lines are never edited |
| JS/TS signature and imports | Parser plus graph call/reference evidence | EXTRACTED / RESOLVED | Explicitly partial where graph reach cannot prove absence |
| Symbol-anchored edit | Indexed parser ranges for every indexed language | EXTRACTED | JS/TS parse gate; other languages retain the parser-range evidence boundary |
