- Integrated head and column limits into JS/Python/Bash/SSH/read output flows, with `:raw` skipping read truncation.
- Documented new output middle-elision and column-cap behavior in `CHANGELOG.md`.
- Added truncation tests for `OutputSink`, `truncateMiddle`, and read-tool line handling.

- Added summarizeCode support with tree-sitter summaries, read.summarize settings, and N-API Summary types/exports.
- Added tests and docs updates for path-embedded selectors, summary behavior, and explicit raw/offset SQL/read cases.
- Updated `read` selector parsing for file and URL reads to accept optional leading `L` and `+` count-style ranges.
- Adjusted truncation notices and schema/help text to emit and suggest `sel` offsets without the `L` prefix, including continuation and suggestion messages.
- Updated hashline/output parsing and related tests to recognize the new `sel` formatting in truncation notices.
- Added minimizer API fields (`MinimizerResult.text`, `settingsHash`) and shell options for minimized output behavior.
- Changed bash execution to print minimized text output and append artifact footers only after minimized output is saved.
- Added UTF-8-safe shell streaming with `on_chunk` callback routing and `replace()` output sink updates.
- Added core filter enhancements for git, cargo, go, and listing/python outputs to produce compact summaries.
- Added RTK command filters and fixtures to strip noise, truncate output, and normalize success fallbacks.
- Standardized missing-file read errors and now return `File not found: <path>` for absent edit targets.
- Centralized AI provider, usage, and OAuth helpers into shared modules to remove duplicated logic.
- Migrated OAuth/API-key login flows to shared factory helpers and removed inline prompt/token-exchange code.
- Reused shared tools and formatter utilities for discovery, stream tails, LSP batching, and source formatting.
- Consolidated repeated test helpers and fixtures into shared modules, replacing inline helper duplicates.
- Simplified TruncationResult interface by making maxLines, maxBytes, and other derived fields optional, reducing redundancy.
- Refactored noTruncResult helper to auto-compute totalLines and totalBytes, eliminating repetitive parameter passing.
- Removed truncatedBy null checks and conditional formatting logic in truncation notice functions for cleaner output.
- Consolidated internal URL handling to use noTruncResult and removed unused displayMode variable.
- Clarified documentation in read.md to distinguish filesystem output from text output formatting.
- Moved artifact management from ToolSession to SessionManager for centralized lifecycle control and caching.
- Replaced getArtifactManager() with allocateOutputArtifact() async method in ToolSession interface for simplified artifact allocation.
- Updated bash, fetch, python, and ssh tools to call session.allocateOutputArtifact() directly with optional chaining fallback.
- Fixed Lobsters scraper to handle user fields as strings instead of nested objects in API responses.
- Refactored byte truncation to use unified `truncateBytesWindowed` function supporting both head and tail modes, reducing code duplication.
- Optimized `truncateHead` and `truncateTail` to avoid full Buffer allocation by processing content incrementally with character-level scanning.
- Improved `TailBuffer.append()` to handle large incoming chunks more efficiently by detecting when a single chunk dominates the tail budget.
- Enhanced `OutputSink.push()` to avoid creating giant intermediate strings when spilling to files by windowing large chunks before concatenation.
- Refactored newline counting to use a constant `NL` for consistency across the module.
- Consolidated truncation and output utilities from tools/truncate.ts and tools/output-utils.ts into session/streaming-output.ts with improved UTF-8 boundary handling.
- Renamed formatSize() to formatBytes() across codebase for consistency and clarity in byte-level formatting.
- Refactored OutputSink to use windowed byte truncation instead of full-buffer encoding, improving memory efficiency on large outputs.
- Migrated from Buffer to Uint8Array in web scrapers for better cross-platform compatibility and native browser support.
- Added getArtifactManager() lazy-initialization method to ToolSession for deferred artifact manager instantiation.
- Simplified API surface with wildcard exports from tools and session modules, reducing import complexity.
- Added `sanitizeText` function to pi-natives that strips ANSI escape sequences, removes control characters and lone surrogates, and normalizes line endings.
- Moved `sanitizeText` function from `@oh-my-pi/pi-utils` to `@oh-my-pi/pi-natives` for better code organization and native performance.
- Added line length clamping (4000 characters) to bash and Python execution output to prevent excessively long lines.
- Replaced internal `#normalizeOutput` methods with `sanitizeText` utility function in bash and Python execution components.
- Fixed bash interactive tool to gracefully handle malformed output chunks by normalizing them with `sanitizeText`.
- Simplified documentation by removing WASM terminology from package descriptions and comments.
- Refactored SSE stream parsing to use generic `readSseJson` utility instead of domain-specific handlers across multiple packages.
- Migrated from Node.js Buffer API to Web standard APIs (Uint8Array, TextDecoder, DataView) for cross-platform compatibility.
- Simplified stream transformation pipeline by consolidating multiple stream operations into unified `createTextLineSplitter` utility.
- Refactored `ptree.ts` to remove complex stream pumping infrastructure and simplify stderr handling with direct async iteration.
- Rewrote stream utilities to operate at binary level with byte-level parsing for improved efficiency and reduced string allocations.
- Updated TypeScript configuration to include DOM.AsyncIterable type definitions for async iterable DOM API support.
- Removed Prettier configuration files (.prettierignore and .prettierrc) and migrated formatting to Biome.
- Updated Biome configuration from version 2.3.11 to 2.3.12 and changed arrowParentheses rule from 'always' to 'asNeeded'.
- Pinned @biomejs/biome dependency to exact version 2.3.12 in package.json and bun.lock.
- Applied consistent arrow function formatting across 489 files by removing unnecessary parentheses around single parameters.
- Removed blank lines after comment blocks and reorganized imports for consistency across the codebase.
