coder::create-file
functionCreate one or more files. Request shape: {"files": [{"path": "...", "content": "..."}]}. Per-file `overwrite` and `parents` flags; non-accessible paths return C211. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*.
filesobject[]*required
modestring
Octal permission bits as a string, e.g. "0644". Defaults to "0644".
overwriteboolean
When false (the default), refuse to write if `path` already exists.
parentsboolean
Create missing parent directories. Defaults to true so a single `coder::create-file` call can scaffold a fresh subtree.
pathstring*required
Path relative to the primary allowed root, or an absolute path inside any allowed root. Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail.

coder::delete-file
functionRemove one or more paths. Request shape: {"paths": ["..."]}. Directories need `recursive: true`; missing paths are idempotent successes; recursive removal refuses to descend through non-accessible entries. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*.

Paths to remove. Each entry is relative to the primary allowed root, or an absolute path inside any allowed root. Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail.

pathstring*required
Canonical absolute path (resolved through the jail); the caller's input verbatim when resolution failed.
Report the coder jail: canonical allowed roots (primary first), per-file size caps, response budgets (max_output_bytes, batch_read_budget_bytes, search_response_budget_bytes), listing/search limits, the non-accessible glob patterns, and the default_exclude_globs noise filter applied by tree/search. Call this FIRST when unsure where coder may read or write, or when a path was rejected — paths outside every allowed root need the shell worker's shell::fs::* instead.
base_pathsstring[]*required
Canonical absolute paths of the allowed roots, in configuration order. The primary root (index 0) is where relative wire paths resolve; an absolute path is accepted when it canonicalises inside ANY of these. Paths outside every root are rejected — use `shell::fs::*` instead.
batch_read_budget_bytesinteger· uint64*requiredmin 0
Aggregate budget across a single `paths[]` batch call to `coder::read-file`, measured in bytes of returned content (after UTF-8 sanitization — invalid bytes expand to U+FFFD before being counted, so the cap bounds what the caller actually receives). Entries are collected in request order; each entry may consume up to `min(remaining_budget, max_read_bytes)`. An entry reached with zero remaining budget receives a per-entry C213 naming this key, its value, and the bytes already consumed, with recovery guidance. Budget topology: batch reads are governed by this key; single-path full reads by `max_output_bytes`; windowed reads by `max_read_bytes` applied per returned window — `max_read_bytes` is also the per-file IO ceiling for all of them.
default_exclude_globsstring[]*required
Noise-exclusion globs (root-relative, same matching as `non_accessible_globs`): matching paths (node_modules, .git, …) are omitted from `coder::search` results and pruned from `coder::tree` descent — the directory surfaces as a childless `truncated` stub. Hide-only — no access protection. Pass `use_default_excludes: false` on those calls to look inside.
list_default_page_sizeinteger· uint32*requiredmin 0
Default `page_size` used by `coder::list-folder` when the caller omits it.
list_max_page_sizeinteger· uint32*requiredmin 0
Hard cap on `page_size` accepted by `coder::list-folder`.
max_output_bytesinteger· uint64*requiredmin 0
Context budget for single-path FULL reads in `coder::read-file`, in bytes of returned content. Full reads larger than this return C213 with the file's size/line count and window/stat recovery guidance; a per-call `max_output_bytes` override is available on `coder::read-file` (clamped to `max_read_bytes`).
max_read_bytesinteger· uint64*requiredmin 0
Per-file IO ceiling for `coder::read-file`. Full reads of files larger than this are rejected with C213; windowed reads cap the returned window bytes instead, so larger files stay readable window by window. Also the ceiling for `coder::search` content scanning — larger files are silently skipped during search.
max_write_bytesinteger· uint64*requiredmin 0
Maximum bytes that `coder::create-file` or `coder::update-file` will accept for a single file write. Larger writes are rejected with C213.
non_accessible_globsstring[]*required
Glob patterns matched per root (root-relative). Files whose root-relative path matches are listable but not readable/writable/deletable/creatable; they return C211.
primary_rootstring*required
Convenience duplicate of `base_paths[0]` — the primary allowed root. Relative paths resolve against this directory.
search_default_max_line_bytesinteger· uint32*requiredmin 0
Per-line byte cap in `coder::search`: matching considers at most this many bytes of each line, and matched/context lines are truncated to it.
search_default_max_matchesinteger· uint32*requiredmin 0
Default `max_matches` used by `coder::search` when the caller omits it.
search_response_budget_bytesinteger· uint64*requiredmin 0
Aggregate byte budget for one `coder::search` response, measured in payload bytes (paths + matched text + context lines). When the budget is hit the response sets `truncated: true` — refine the query or add `include_globs`.
tree_default_depthinteger· uint32*requiredmin 0
Default `max_depth` used by `coder::tree` when the caller omits it.
tree_per_folder_limitinteger· uint32*requiredmin 0
Maximum entries returned per folder node by `coder::tree`; folders that exceed this are flagged `truncated`.
versionstring*required
Coder worker version (`CARGO_PKG_VERSION`).
coder::list-folder
functionPaginated single-folder listing, sorted by name. Entries carry only `name`; derive an entry's absolute path as the response's `path` + '/' + name. Non-accessible entries are still listed with a `non_accessible: true` flag. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*.
page_sizeinteger· uint32min 0
Capped by `config.list_max_page_size`; falls back to `config.list_default_page_size` when omitted.
pathstring
Folder to list. Relative to the primary allowed root, or an absolute path inside any allowed root. Defaults to `.` (the primary root itself). Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail.

totalinteger· uint64*requiredmin 0
Move or rename one or more paths inside the jail. Request shape: {"files": [{"from": "...", "to": "..."}]}. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*. Per-entry `overwrite` and `parents` flags. Same-root moves use a per-file-atomic rename; cross-root moves use copy+delete (files only — cross-root directory moves are unsupported, move files individually). Copy+delete is rollback-safe: if source deletion fails after a successful copy the copy is removed and the error names the failure; if rollback also fails the error names both states for manual cleanup.
filesobject[]*required
Entries to move. Each entry is processed independently so a single failure never aborts the rest.
fromstring*required
Source path: relative to the primary allowed root, or an absolute path inside any allowed root. Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail.
overwriteboolean
When false (the default), refuse to overwrite an existing destination. Pass `overwrite: true` to replace an existing file at `to`.
parentsboolean
Create missing parent directories of the destination. Defaults to true.
tostring*required
Destination path: relative to the primary allowed root, or an absolute path inside any allowed root. Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail.

Read a file window-first: probe with stat: true (size/mtime/mode plus total_lines, no content), then fetch just the lines you need with line_from/line_to (1-based, inclusive) — windows keep files larger than max_read_bytes readable window by window, with more_lines/total_lines reporting what remains. numbered: true prefixes each line with its absolute 1-based file line number, matching coder::update-file's line ops exactly. Full reads are budgeted by max_output_bytes (default 128 KiB; per-call override clamped to max_read_bytes) — an over-budget full read fails with a C213 carrying the file's size, line count, and the window/stat recovery calls. Batch mode: pass paths[] (XOR path) to read multiple files in one call — entries are processed in request order against batch_read_budget_bytes, measured in bytes of returned content (after UTF-8 sanitization); per-entry errors (C211/C213) leave other entries unaffected. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*. Non-accessible paths return C211.
line_frominteger· uint64min 1
First line of the window, 1-based inclusive (must be >= 1; 0 is rejected with C210). Setting `line_from` and/or `line_to` switches to windowed mode: the file is streamed and only the requested lines are returned, so files larger than `max_read_bytes` stay readable slice by slice — the byte cap then applies to the returned window, never the file size. Defaults to 1 when only `line_to` is set. A window starting past EOF succeeds with empty content and reports the file's `total_lines`. Only valid in single-path mode (`path`); ignored when `paths` is set. Lines are 0x0A- or EOF-terminated segments; a trailing newline does not create a phantom line (same convention as `coder::update-file`).
line_tointeger· uint64min 1
Last line of the window, 1-based inclusive. Must be >= `line_from` (C210 otherwise). Omit to read from `line_from` to end-of-file (still bounded by `max_read_bytes` on the returned bytes). Only valid in single-path mode (`path`); ignored when `paths` is set.
max_output_bytesinteger· uint64min 0
Per-call override of the `max_output_bytes` config (default 131072) that budgets single-path FULL reads, measured in returned content bytes after UTF-8 conversion (numbered prefixes included). Values above `max_read_bytes` are silently clamped to it. When the full content would exceed the effective budget the call fails with a C213 naming the file's size and `total_lines` — recover by windowing with `line_from`/`line_to`, probing with `stat: true`, or raising this field. Full reads only: combining it with `line_from`/`line_to` is C210 (windows are bounded by `max_read_bytes` instead); ignored when `paths` is set (batch mode is governed by `batch_read_budget_bytes`).
numberedboolean
When true every returned content line is prefixed `N→`, where N is the line's ABSOLUTE 1-based number in the file — a window starting at `line_from: 40` is numbered from 40, not 1. Numbers match `coder::update-file`'s 1-based line ops exactly, so you can go from a numbered read straight to a line edit. Prefix bytes count toward all byte caps and budgets (no hidden bypass). C210 with `stat: true` (no content to number). Batch entries take a per-entry `numbered` field instead; this top-level flag is ignored when `paths` is set.
pathstring
Single file to read. Relative to the primary allowed root, or an absolute path inside any allowed root. Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail. Mutually exclusive with `paths` (XOR): pass either `path` or `paths`, not both — C210 if both or neither is set.
pathsany of[]
Batch of files (or windowed slices) to read in a single call. Each entry is either a plain path string (whole-file read) or an object `{path, line_from?, line_to?}` with per-entry window parameters. Entries are processed in request order against a shared `batch_read_budget_bytes` cap, measured in bytes of returned content (after UTF-8 sanitization) — see `coder::info` for the configured value. Results are returned in the `results` field; top-level fields are null. Mutually exclusive with `path` (XOR): pass either `path` or `paths`, not both — C210 if both or neither is set.

Last line of the window, 1-based inclusive. Must be >= `line_from` (C210 for this entry otherwise). Omit to read from `line_from` to EOF.
numberedboolean
Prefix this entry's content lines with their absolute 1-based file line numbers (`N→`) — same semantics as the top-level `numbered` field. Prefix bytes are charged against `batch_read_budget_bytes`.
pathstring*required
File to read. Same jail rules as the top-level `path` field.
statboolean
Per-entry metadata probe: same semantics as the top-level `stat` field — size/mode/mtime always, `total_lines`/`is_utf8` when the file fits `max_read_bytes`, content null, no batch budget consumed. C210 when combined with this entry's `line_from`/`line_to` or `numbered`.
statboolean
Metadata probe — the cheap "how big is it" call. When true the response carries size/mode/mtime plus `total_lines` and `is_utf8` (both null when the file exceeds `max_read_bytes` — size/mode/mtime still populate, so stat on a huge file SUCCEEDS); `content` is null, `lines_returned` 0, `more_lines` false. Probe BEFORE reading an unknown file, then fetch just the slice you need with `line_from`/`line_to`. Mutually exclusive with `line_from`, `line_to`, `numbered`, and `max_output_bytes` (C210 — stat returns no content for them to act on). Batch entries take a per-entry `stat` field instead; this top-level flag is ignored when `paths` is set.
contentstring
File content as a UTF-8 string — the whole file, or just the requested window when `line_from`/`line_to` was given (window lines keep their newline terminators). Binary content is returned with invalid bytes replaced by U+FFFD; use a future binary-aware function if exact bytes matter. **Single-path mode only; null when the request used `paths[]`.**
is_utf8boolean
Whether `content` survived UTF-8 conversion without losing bytes. Reflects the RETURNED content only: a clean window inside an otherwise-binary file is still `true`. **Single-path mode only; null when the request used `paths[]`.**
lines_returnedinteger· uint64min 0

mtimeinteger· int64
Last-modified time as a Unix epoch in seconds. **Single-path mode only; null when the request used `paths[]`.**

Total number of lines in the file. Present only when the read traversed the whole file: always for full reads; for windowed reads only when the stream naturally reached EOF within the byte cap. Never computed by forcing an extra full scan — absent means the file was not fully traversed. **Single-path mode only; null when the request used `paths[]`.**
Search file contents and/or paths. Supports literal or regex queries with include/exclude globs; non-accessible files are excluded from both content and path results. Only the FIRST match on each line is reported (one content match per matching line). Optional context_lines_before/context_lines_after (max 10) attach surrounding lines to each content match so many edits can go straight to coder::update-file with no read in between. Noise paths matching default_exclude_globs (.git, node_modules, target, … — coder::info lists them) are skipped by default; pass use_default_excludes: false to search inside them. Files larger than max_read_bytes are silently skipped during content scanning. Results are capped by max_matches AND a response byte budget (search_response_budget_bytes); when truncated is true, refine the query or add include_globs rather than paginate. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*.

context_lines_beforeinteger· uint32min 0
Lines of context to return BEFORE each content match (same file only, in file order), max 10 — larger values are rejected with C210. With context lines many edit tasks can go straight from search output to coder::update-file with no read in between. Context lines are truncated to `max_line_bytes` like the matched text and count toward the response byte budget. Unset = 0.

Folder scoping the walk. Relative to the primary allowed root, or an absolute path inside any allowed root. Defaults to `.` (the primary root itself). Globs are matched relative to the containing root; result paths are absolute regardless of this value. Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail.

Recursive directory snapshot bounded by `max_depth` and a `per_folder_limit`. Slim wire shape: nodes carry only `name` — the root node's path IS the response's top-level `path`; derive any child's path as parent path + '/' + name. Folders that hit the limit are flagged `truncated` and the caller is pointed at coder::list-folder for pagination. Noise directories matching default_exclude_globs (.git, node_modules, target, … — coder::info lists them) appear as childless `truncated` stubs; pass use_default_excludes: false to descend into them. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*.
max_depthinteger· uint32min 0
Maximum depth to descend; the root node is depth 0.

coder::update-file
functionApply batched line-oriented and regex edits across one or more files. Request shape: {"files": [{"path": "...", "ops": [...]}]}. Line ops: { op: 'insert', at_line, content } | { op: 'remove', from_line, to_line } | { op: 'update_lines', from_line, to_line, content } — 1-based, inclusive, applied bottom-up. Regex op: { op: 'replace', pattern, replacement, ignore_case?, dot_matches_newline?, expect_matches? } runs on the file body after line ops. Replace large regions WITHOUT quoting them: two short anchors joined by .*? with dot_matches_newline: true — always prefer wildcards over pasting the block into the pattern. expect_matches: 1 turns a silent multi-site clobber into a safe pre-write C210; expect_matches: 0 asserts absence. In `replacement`, $1/${name} are capture references and a literal $ must be written $$ (JS/TS template literals: `Hello, $${name}!`); undefined references fail pre-write with C210. Each file commits atomically via temp + rename. On success each applied line op returns a bounded post-apply echo (±2 context lines); regex replace ops return up to 5 per-match-site echoes (first + last line of each replaced region, inner lines elided) — verify from the echoes instead of re-reading the file. Paths are relative to the primary allowed root or absolute inside any allowed root (coder::info lists them); for host paths outside the jail use shell::fs::*.

dot_matches_newlineboolean
When true, `.` in `pattern` also matches `\n`, so a short anchored pattern like `"fn parse_config\\(.*?\\n\\}"` replaces a whole multi-line region without quoting it — prefer two short anchors joined by `.*?` over pasting the block into the pattern. Without this flag (the default), `.` does not cross newlines and a multi-line pattern silently matches nothing.
expect_matchesinteger· uint64min 0
Expected number of matches for this op. When set and the actual count differs, this FILE fails with C210 and nothing is written to it (other files in the batch still apply). Set `expect_matches: 1` to make a targeted read-free edit safe — a mismatch means the pattern is anchored too loosely or matches nothing. Set `expect_matches: 0` to assert ABSENCE: the op succeeds only when nothing matches (the replacement is unused). Omit to replace all matches unconditionally.
opstring*requiredenum: replace
replacementstring*required
Substitution text for each match. Capture references expand: `$1`/`${1}` by index (`$0` is the whole match) and `$name`/`${name}` by name. A literal `$` MUST be written `$$` — JS/TS template literals in a replacement are the classic collision: write `Hello, $${name}!` to output `Hello, ${name}!`. Unbraced references consume the longest `[0-9A-Za-z_]` run, so `$1a` means a group named "1a", NOT group 1 then "a" (use `${1}a`). A reference to a group the pattern does not define fails pre-write with C210 — nothing is written. References are validated even when the replacement goes unused (e.g. `expect_matches: 0`): the replacement must be well-formed even when unused.
pathstring*required
Path relative to the primary allowed root, or an absolute path inside any allowed root. Call `coder::info` to see the allowed roots. Paths outside every allowed root are rejected — use the shell worker's `shell::fs::*` for host paths outside the jail.
resultsobject[]*required
appliedinteger· uint32*requiredmin 0
Number of operations applied (only meaningful when `success`).
echoesobject[]*required
Per-op bounded post-apply echoes for edit verification; each applied op returns a snapshot of the affected region (±2 context lines) so the caller can confirm the edit landed at the right position without receiving the full file body. See `OpEcho` for field semantics. Empty on failure. Always present on the wire.
elidedinteger· uint64min 0
Number of middle lines elided from a large region: for line ops, set when the affected region exceeded the per-echo cap; for replace sites, the count of inner lines between the region's echoed first and last line (set when the region spans >2 lines).
from_lineinteger· uint64*requiredmin 0
1-based line number of the first echoed line (after all ops applied).
linesstring[]*required
The echoed lines, post-apply. When the region is large, middle lines are elided and `elided` is set to indicate how many were skipped.
op_indexinteger· uint32*requiredmin 0
Index of the op in the request's ops array (0-based).
total_replacementsinteger· uint64min 0
Total number of replacements the regex op made across the whole file (set only on replace-op site echoes, duplicated on each site). Sites are capped at 5 — when more matched, this count is the only record of the extras.
echoes_truncatedboolean*required
True when the total echo budget (~4 KiB) was exhausted before all op echoes could be emitted. Use `coder::read-file` to inspect the full result if needed. Always present on the wire.
errorany of
Structured error for this entry. `code` is stable for programmatic branching (e.g. `"C211"` for not-found-or-denied; `"C210"` for bad input such as overlapping ops). `message` carries the corrective action an LLM agent needs to make a successful second call.

Run a command in the foreground and return its full output. Put the program name in `command` (string) and arguments in `args` (string[]) — do NOT pass argv as an array in `command`. `timeout_ms` is capped at the configured max; negative/fractional values fall back to the default. `target` defaults to the host; pass { kind: "sandbox", sandbox_id } to run in a microVM. Optional host-only `cwd` scopes this call to a directory (jail-confined exactly like shell::fs::* paths; escaping it is S215), optional `env` (object) sets per-call values for ANY key except PATH/IFS/HOME/LD_*/DYLD_* or other loader/lookup and interpreter-startup keys (those reject S210 unconditionally) — and optional host-only `stdin` (string) is written to the program's standard input (use it for `tee`, `patch`, or any stdin filter instead of a shell heredoc). cwd/env/stdin on a sandbox target reject S210. Backend errors return { code, message }; common: S216 host exec error, S300 VM boot failed, S200 in-VM failure. argv-parse and denylist rejections are plain-string messages naming the violation.
argsstring[]
Arguments passed to the program, in order. Every element must be a string; non-string elements are rejected by index. `None` (or `args: null` / absent) means "tokenize `command` via shell-words"; `Some(_)` (including the empty vec) means "use args verbatim, no shell-words." See `parse_argv` in `crate::exec::host`.
commandstring*required
Program name (bare, PATH-resolved) or a path to an executable. Must be a string — split arguments into `args`, do not pass argv as an array here.
cwdstring
Optional working directory for this call (host target only). Confined to the fs jail exactly like `shell::fs::*` paths: jail-relative when `fs.host_roots` are set (else absolute), canonicalized, and must resolve inside a jail root and miss the denylist — a path that escapes returns S215. Must already exist and be a directory. Omit to use the configured `working_dir` (unchanged default). Rejected (S210) on a sandbox target.
envobject
Optional per-call environment values (host target only). Deny-only: a key may be set to ANY value except an exec-hijacking key (PATH, IFS, HOME, LD_*/DYLD_*, and other loader/lookup and interpreter-startup keys — see DANGEROUS_ENV_KEYS), which is rejected unconditionally (`env.allow` plays no role here — that list only gates which vars get forwarded from the worker's own environment). Supplying a dangerous key rejects the WHOLE call (S210) naming the offending key; the env is never silently dropped. Values override what would otherwise be forwarded for that key. Rejected (S210) on a sandbox target.
stdinstring
Optional bytes written to the program's standard input, followed by EOF. Use this to pipe content to a command that reads stdin (`tee`, `patch`, `cat`, a filter) instead of wrapping it in a shell heredoc. Omit to leave stdin closed (`/dev/null`, the default). HOST target only — rejected (S210) on a sandbox target, like cwd/env.

Spawn a command as a background job; returns { job_id, argv } immediately. Same payload as shell::exec (command + args, do NOT pass argv as an array), including the optional host-only `cwd` (jail-confined; escape is S215), `env` (any key except PATH/IFS/HOME/LD_*/DYLD_* or other loader/lookup and interpreter-startup keys, rejected unconditionally), and `stdin` (string written to the job's stdin); violations and cwd/env/stdin on a sandbox target reject with an S210 message. Poll with shell::status, terminate with shell::kill, list with shell::list. Host background jobs ignore the per-call timeout_ms and run until they exit or shell::kill terminates them; set the operator config `max_bg_timeout_ms` (0 = unbounded, the default) to force-kill a runaway job after that long. Spawn-time failures (argv-parse, denylist, cwd/env gating, spawn, concurrency cap) are plain-string messages naming the violation; once spawned, per-job failures surface through shell::status (the job record's status/stderr), not this call's return.
argsstring[]
Arguments passed to the program. See [`ExecRequest::args`]. `None` (or `args: null` / absent) means "tokenize `command` via shell-words"; `Some(_)` (including the empty vec) means "use args verbatim, no shell-words." See `parse_argv` in `crate::exec::host`.

Program name. See [`ExecRequest::command`].
cwdstring
Optional working directory for this job (host target only). Same jail confinement and rules as [`ExecRequest::cwd`]: canonicalized, must resolve inside a jail root (S215 on escape) and be an existing directory. Rejected (S210) on a sandbox target.
envobject
Optional per-call environment values (host target only). Same gating as [`ExecRequest::env`]: deny-only, rejecting only an exec-hijacking key (PATH, IFS, HOME, LD_*/DYLD_*, and other loader/lookup and interpreter-startup keys — see DANGEROUS_ENV_KEYS); any violation rejects the whole call (S210). Rejected (S210) on a sandbox target.

Write a file. Simplest form: { path, content: "text" } — `content` as a plain STRING is written inline (host target only), no streaming channel needed. For large/streamed payloads or a sandbox target, pass `content` as a ContentRef { channel_id, access_key, direction } from a write stream channel you opened through the engine's streaming layer (inline strings reject S210 on a sandbox target). To write several files at once, pass `files: [{ path, content, mode?, parents? }, ...]` instead of the single-file fields (host target, inline content) — the response then carries per-file results in `files`. `mode` is octal (default "0644"); `parents: true` creates missing parents. Errors return { code, message }; common: S210 bad mode/payload or inline-on-sandbox, S215 jail/denylist, S218 payload exceeds max_write_bytes, S216 channel/IO error.
