The auto-download mechanism for ripgrep existed but was never called.
When 'rg' wasn't in PATH, the grep tool silently fell back to GNU grep,
which wastes ~10% token budget due to noisy results.
Changes:
1. Wired up resolveGrepCliWithAutoInstall() in the CLI resolution path
2. When 'rg' is not found in PATH, auto-downloads ripgrep v14.1.1
3. Caches the downloaded binary in OpenCode data directory
4. Falls back to GNU grep only if auto-download fails (with warning)
Fixes#3003
When models pass relative paths (e.g. 'apps/ios/CleanSlate') to glob/grep
tools, they were passed directly to ripgrep which resolved them against
process.cwd(). In OpenCode Desktop, process.cwd() is '/' causing all
relative path lookups to fail with 'No such file or directory'.
Fix: use path.resolve(ctx.directory, args.path) to resolve relative paths
against the project directory instead of relying on process.cwd().
- Use tool.schema.enum() for output_mode instead of generic string()
- Remove unsafe type assertion for output_mode
- Fix files_with_matches mode returning empty results by adding
filesOnly flag to parseOutput for --files-with-matches rg output
- Add --threads=4 flag to all rg invocations (grep and glob)
- Add global semaphore limiting concurrent rg processes to 2
- Reduce grep timeout from 300s to 60s (matches tool description)
- Reduce max output from 10MB to 256KB (prevents excessive memory usage)
- Add output_mode parameter (content/files_with_matches/count)
- Add head_limit parameter for incremental result fetching
Closes#2008
Ref: #674, #1722
Convert grep, glob, ast-grep, and session-manager tools from static exports to factory functions that receive PluginInput context. This allows them to use ctx.directory instead of process.cwd(), fixing issue #658 where tools search from wrong directory in OpenCode Desktop app.
Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode)

ToolContext type from @opencode-ai/plugin/tool does not include
a 'directory' property, causing typecheck failure after rebase from dev.
Changed to use process.cwd() which is the same pattern used in
session-manager/tools.ts.
