Shell and Python edits do not expose filesystem mutation intents, so a working directory without Git cannot reliably present those edits in the turn Review tab. A patch tool expresses related edits in one call while retaining guarded filesystem operations. #5121 asks for the capability and its effectiveness evaluation; #4556 supplies the broader motivation for efficient file editing. + +## Decision + +`apply_patch` accepts one Codex-style patch for add, update, delete, and move operations, including multiple files and hunks. The pure [dsh-fs-patch library](../../../../packages/fs/fs-patch/README.md) follows Codex `rust-v0.158.0` parsing, sequential matching, whitespace tolerance, and `NormalizeToLf` reconstruction; the matcher receives LF text only, so Codex `PreserveLineEndings` is not implemented. + +The [filesystem service](../../../../packages/fs/fs/README.md) exposes `patchText`, `deleteFile`, and `moveFile`; local, sandboxed, and SSH providers implement them. `fs/delete-intent` requires the same present observation as `fs/edit-intent`, while move destinations use `fs/write-intent`. Version guards and sandbox enforcement remain with the provider. A move publishes its destination before deleting its source, and `sourceDeleted` distinguishes a completed move from a published destination whose source could not be removed. + +The [tool executor](../../../../packages/fs/tool-fs/README.md) resolves paths and simulates expected state during whole-patch preflight, including repeated paths and moves, without writing files; a refused preflight commits nothing. Commit reobtains observation guards for each operation and stops at the first failure or cancellation without rollback. After an I/O or cancellation failure, a `stat` comparison checks whether every affected target retains its prior version; changed state or a failed comparison produces `unknown`, which requires rereading before retry. Reports retain completed, failed, unknown, and skipped operations, including a partially published move. + +Commit reports return `isError: false` so completed diff metadata survives a stopped patch; their operation statuses and stopped flag expose the failure. Syntax and preflight rejection produce tool errors. Successful move summaries use `M `. Applied diff paths use canonical absolute `processPath` for client navigation, while operation records retain display paths and unresolved paths keep their patch spelling. + +[Review capture](../../../../packages/deliverables/workspace-changes/README.md) uses filesystem intent listeners, not argument parsing. `tools/pre-execute` associates the execution with its turn recorder; prepended write, edit, and delete listeners first await the policy decision, then await capture before provider mutation. Moves capture both endpoints. Each turn retains its first baseline and compares actual final bytes, so repeated edits yield one net diff and reverted changes disappear. Existing size, count, time, location, and Session-lifetime limits remain. + +`tool-fs.applyPatch` defaults to `false`, so every shipped composition keeps the model request it had before the tool existed; the `tool-fs` rows that enable `edit` (`dsh-base` and the Web `standard`, `ptc`, and `cordis` presets) state `applyPatch: false`, and a deployment turns the tool on by changing that one line, or by a profile patch on the `tool-fs` id where no preset owns the row. The tool consults the `fs/*` intent waterfalls like `write` and `edit`, so the mounted observation policy requires a prior read and rejects stale versions for every patch operation. The schema names its argument `input` as the Codex tool does: across 2,226 recorded DS-Bench and DeepSWE rollouts, 14% of `apply_patch` calls arrived with that key and were rejected while the argument was named `patch`. The tool registers its schema, guidance, native/PTC execution, and tool presentation through plugin effects; the agent loop is unchanged. + +## Alternatives considered + +**Keep using shell or Python for patches.** This leaves non-Git changes without filesystem intent capture and does not provide the requested model-facing editing tool. + +**Reuse Codex markers with an independently strict matcher.** This reduces initial implementation work but makes familiar patches fail differently. A pinned Codex parser and matcher make deviations reviewable; Harness policies stay explicit. + +**Make the whole patch transactional.** Cross-file rollback adds recovery state and can overwrite concurrent external edits. Preflight and ordered commits reject known failures early and expose partial results without promising rollback. + +**Expand Review while adding the tool.** Rename presentation, persistent storage, SSH capture, and capture-failure policy are independent product decisions; existing whole-file capture and rendering cover this integration. + +**Register the tool by default wherever `write` and `edit` are both enabled.** This would add a schema and a guidance section to every default model request and change every recorded request expectation before the tool's effect on ordinary sessions is measured; the explicit switch keeps the baseline composition unchanged and lets comparison runs opt in. + +## Consequences + +One call can express related edits. Default model requests are unchanged; a composition that enables the switch includes another tool schema and its guidance, so its recorded request expectations differ from the baseline. Preflight cannot prevent a later conflict, cancellation, or storage failure; callers inspect operation statuses before retrying. Permissive upstream matching remains pinned and tested rather than tightened. Provider implementations and external subclasses must support three additional operations, and partial moves require handling both endpoints. + +## Testing + +Parser and matcher fixtures cover the pinned syntax, whitespace, repeated contexts, and EOF behavior. Provider and executor tests cover observation, version and sandbox refusals, repeated paths, partial moves, cancellation, and uncertain outcomes. The real-tool Review matrix runs with no repository and with Git unavailable, checking all operation kinds, first-to-last baselines, rejected edits, partial publication, reverted changes, capture ordering, malformed syntax, and path aliases. Real model Session recordings cover successful updates, read-policy rejection and retry, and partial execution; deterministic cancellation stays in executor tests. + +## Deferred + +A controlled editing-task evaluation comparing final-file correctness, task success, tokens, tool calls, retries, latency, and Review coverage against `edit` on identical initial states.

Question rows pair answers with questions by id, using the tool result or the `userQuestions` projection for late replies. An answerable call has a button to reopen its panel. Once a late reply is in the agent Inbox, the row shows its submitted answers; “View answers” expands its read-only transcript while admission is pending. A settled call with answers opens the panel read-only. Closed calls without answers and invalid records offer no button. Cancelled and interrupted rows show their verdict without inventing answers. If no panel provider accepts the button action, it expands the row.

Reads then go `stat` → `readText`/`streamText`/`readBytes`/`readByteRange`, listings go `listDir`, and mutations go through one per-target critical section: the optional guard is checked, the new content is applied, and the result is published atomically. +Every operation uses a target from `resolve(path, { cwd })`; aliases share an opaque identity. Cross-capability coordinates come from the provider. Single-file mutations own their version check and atomic publication. A move acquires both target locks in lexical order and releases them in reverse order; destination publication and source removal remain separate effects. ### The `fs/*` policy events -The package declares three events so the emitter (`dsh-tool-fs`) and the policy listener (`dsh-fs-observation-policy`) share a vocabulary without the emitter depending on the policy plugin. `fs/write-intent` and `fs/edit-intent` are single-slot decision waterfalls: the first listener decides outright and never calls `next()`. `fs/observed` is a fire-and-forget recording event carrying an `FsObservation` — present with a version, or confirmed absent. The events carry only `dsh-fs` vocabulary plus an opaque `object` actor. +The package declares four events shared by consumers and observation policy. Intent waterfalls have one decision owner; observation recording is synchronous and carries an opaque actor.

The per-tool executors live in `src/read.ts`, `src/read-image.ts`, `src/write.ts`, and `src/edit.ts`. +The internal patch executor accepts a raw patch and an already resolved sandbox policy. It builds an ordered plan, preflights all operations against simulated state, then commits through `writeText`, `patchText`, `deleteFile`, or one `moveFile` call. A refused preflight operation has no simulated effect, and any refusal prevents every write. Sandbox containment is not simulated: the provider decides it at each commit, as for `write` and `edit`, so a denied operation stops the patch with the earlier operations retained. A syntax report carries the parser failure; a preflight report lists the refused operations; a commit report keeps one entry per operation with `completed`, `failed`, `unknown`, or `skipped` status and known LF text changes. Unresolved paths retain their raw patch spelling; resolved paths use provider display paths. Programming errors reject the call. + ### Observation and concurrency `fs/observed` fires after the operation succeeded via a plain `ctx.emit`; a listener is contractually a synchronous, side-effect-only recorder, so async or fallible observation does not belong on this event. `read` opts into concurrent scheduling because its only mutation is the synchronous version recorder; recorder races fail closed when a later `write` or `edit` re-checks the version under its target lock, and both mutation tools remain exclusive. +Patch preflight reads never emit `fs/observed`. The first preflight operation on a target dispatches its intent; later operations on that target use the simulated state. Each commit dispatches its intents again to obtain current guards. Add and update record presence, delete records absence, and move records its destination plus source absence only after successful removal; a partial move is `failed` with a destination-only change. The move source baseline comes from `moveFile` under its lock. + +After a mutation rejects with `FS_IO_ERROR`, the executor compares each affected target's version with a fresh `stat`. Unchanged targets mean a known failure; a changed target or failed comparison means `unknown`, which records no observation or change. `FS_ABORTED` is always `unknown`: a cancelled remote request rejects while the provider may still be writing. Execution stops at the first failed or unknown commit, or before an operation whose signal is aborted. +

The system prompt is surface node 0, logged as a `system/message` event before the step's first `request/header`; every fixture stores its text block as `"text":"{{system}}"` and the prompt sidecar keeps the full text. The pin's `request/header` events store `"tools":"{{tools}}"` while retaining config and reason, and the structured schema sidecar keeps the full catalogs. Logs containing developer messages retain ordered tool names in each header instead of the token so historical addition references remain verifiable. A child Session whose own scope composes a different request declares it per fixture index with `pinsChildToolSchemas` and `pinsChildSystemPrompts`. A scenario that changes the request header mid-run declares `expectedHeaderChanges`; a scenario whose prompt changes mid-run — replacing node 0, or appending after the cached history on an `in-history` route — declares `expectedPromptChanges`, and each change adds a `` section to the prompt sidecar.
