- Reworked message parsing to process complete frames from a pending chunk queue.
- Added chunk-aware header scanning and range copy to avoid repeated buffer concatenation.
- Persisted partially read bytes in client.messageBuffer during reader teardown.
Returned the current workspace folder list when a server queried workspace/workspaceFolders after initialization so advertising the capability no longer left late requests answered with -32601.
Ensured rust-analyzer textDocument/didOpen ran before workspace readiness polling so the server could discover the file's Cargo workspace, and skipped the readiness wait entirely for standalone .rs files outside any Cargo workspace ancestor.
Continued rust-analyzer workspace readiness polling across transient analyzerStatus request timeouts while preserving early exit for unsupported methods and server failures.
Advertised workspace folder support during LSP initialization and waited for rust-analyzer to finish loading Cargo workspaces before opening project-indexed files.
Fixes#1976
- Added `DiagnosticsLedger` to track diagnostics already surfaced per file, suppressing repeats within a session.
- Wired dedup into both edit and write tools via a `transformDiagnostics` hook on the writethrough pipeline.
- Added `lsp.diagnosticsDeduplicate` setting (default: true) to control the behavior.
Send the LSP exit notification after a successful shutdown response before falling back to process termination. Add a regression test that fails when a server receives shutdown but not exit.\n\nFixes #1593
- Added `ToolTier`, `ToolApproval`, and `ToolApprovalDecision` types and exported approval APIs.
- Updated approval-mode options from `auto|prompt|custom` to `always-ask|write|yolo` and defaulted mode to `yolo`.
- Changed approval resolution to apply per-tool decisions first, then mode-tier limits, with legacy-mode migration.
- Assigned read/write/exec `approval` and approval-detail prompts across built-in, custom, extension, and MCP tools.
- BARE_IDENTIFIER_RE accepts $-prefixed names ($store, $count, RxJS/Svelte/
Angular). Word-boundary check now fires on those names, so searches no
longer return the offset inside a compound identifier like bar$store.
- applyWorkspaceEdit walks documentChanges in declared order, flushing
per-URI text edits immediately before any subsequent resource op for the
same URI. Folder rename/delete ops flush every pending URI under the
affected subtree. Rename ops also flush pending edits queued against
renameOp.newUri (and descendants) before fs.rename runs.
- Legacy changes-map-only WorkspaceEdit payloads are unchanged.
Loaded marketplace lspServers metadata from Claude plugin caches and embedded it for OMP marketplace installs so config-only plugins register without package code.
Fixes#1352
Three independent lsp fixes that share the action dispatcher and import
graph in lsp/index.ts:
- symbol-required: project-aware references/rename/definition now reject
an omitted symbol with a structured error pointing at symbol=<name>
(and symbol#N for repeats). resolveSymbolColumn used to fall back to
the first non-whitespace column and the server happily answered for
whatever identifier sat there. findSymbolMatchIndexes also enforces
word boundaries for bare identifiers.
- timeout-distinguish: the outer catch around dispatched LSP actions
rethrew new ToolAbortError() for both an internal timeoutSignal abort
and a caller signal abort, so callers got an opaque "Operation
aborted". Timeouts now map to a ToolError that names the action and
the elapsed budget; caller cancels stay ToolAbortError.
- edit-coalesce: rename and rename_file collected edits from every
project-aware server and applied them sequentially, but each server
computed positions against pre-edit text. Once server A wrote, server
B's edits had stale offsets and produced malformed imports. Merge
per-uri edits across servers, sort by descending position, and throw
on overlap so the model retries instead of silently corrupting.
- Replaced all StringEnum(...) usages with z.enum([...]) across tools, examples, and tests.
- Removed StringEnum re-export from @oh-my-pi/pi-coding-agent public API.

- Updated AI provider adapters and MCP/agent builders to convert tool params through `toolWireSchema()`.
- Reworked schema validation from AJV to Zod-safe parsing with `fromTypeBox`, `toolWireSchema`, and meta schema checks.
- Updated root marker detection to read the directory once and match glob markers against top-level entries, preventing recursive scans when checking project roots.
- Adjusted root-marker glob error handling to warn on directory listing failures and treat the marker set as absent when unreadable.
- Reduced marksman's configured warmup timeout from 15,000 ms to 2,000 ms in LSP defaults.
- Updated LSP diagnostics output to return "OK" when no issues were found.
- Added a diagnostics-specific render case to show successful status and a success label for "OK" responses.

- Added schema updates and client file-operation capabilities to advertise rename support.
- Added regression tests for rename behavior, preview mode, and request/capabilities flows.
- Fixed bash interceptor to check both raw and cwd-normalized commands, catching commands hidden behind leading `cd ... &&` wrappers.

- Fixed concurrent bash command tracking by replacing a single abort controller with a Set, preventing premature cancellation of parallel commands.
- Removed `./hooks` and `./hooks/*` export entries from the coding-agent package exports map.

- Added compact Lark grammar processing and applied it to OpenAI custom-format tools before conversion.
- Reworked atom mode into `---PATH` compact commands with new grammar, parser, and rm/mv file operations.
- Updated `hline`/`href`/`hrefr` helper behavior and hashline mismatch guidance using shared anchor state.
- Standardized path formatting with `formatPathRelativeToCwd` across LSP, prompts, and edit/search/write tools.
- Added benchmark run-path handling, including `.gitignore` runs mapping, absolute reports, and safer snapshot output.

- Simplified diagnostic grouping output in the LSP utility to use plain `## file` headers.
- Adjusted AstEdit, AstGrep, and Grep tools to emit file headings without the `└─` tree prefix.

- Removed built-in `taplo` from `src/lsp/defaults.json`, so TOML files no longer start a default LSP server.
- Condensed many `defaults.json` arrays and option blocks to a compact single-line style.
- Limited strict tool candidates to a named allowlist instead of all opt-in tools.
- Fixed `minItems` stripping to target object-typed schema nodes, not just arrays.

Servers like marksman (.NET) write [INF]/[DBG] startup logs to stderr.
peekStderr() captures these and includes them verbatim in the warning
message, producing confusing output.
Filter timestamped [INF]/[DBG]/[VRB] lines before surfacing stderr as
error messages. Also give marksman a 15s warmupTimeoutMs — its .NET
runtime needs longer than the 5s default on arm64.
