* fix(vitest): robust JSON extraction for pnpm/dotenv prefixes
Problem: RTK's vitest parser forces --reporter=json but pnpm/dotenv prepend
non-JSON text to stdout (banners, env messages), causing 100% Tier 1 failure
and useless 500-char passthrough.
Solution:
- Add extract_json_object() to parser/mod.rs (shared utility)
- Algorithm: find "numTotalTests" or first standalone {, brace-balance forward
- VitestParser now tries direct parse → extract+parse → regex → passthrough
- Replace hardcoded Command::new("pnpm") with package_manager_exec("vitest")
- Delete orphan doc comment on line 203
Impact:
- Before: 100% Tier 3 passthrough with pnpm workflows
- After: Tier 1 success with prefixes, maintains 99.5% token savings
Tests:
- 6 tests for extract_json_object (clean, pnpm, dotenv, nested, no-json, strings)
- 3 tests for VitestParser with prefixes
- All 277 tests pass

* chore(benchmark): add vitest, pnpm, and gh commands
Add benchmarks for recently implemented commands:
- vitest run (PR rtk-ai#92 - JSON extraction fix)
- pnpm list/outdated (PR rtk-ai#6)
- gh pr list/run list (existing gh support)
These commands are now tested in CI to ensure token savings are maintained.

The sections only ran when these project files existed. **Solution:** 1. Create temporary fixtures with minimal project structure: - Python: pyproject.toml + sample.py + test_sample.py - Go: go.mod + main.go + main_test.go 2. Resolve RTK to absolute path to work after cd into temp dirs 3. Install required tools in CI workflow: - Python: ruff, pytest - Go: stable version + golangci-lint **Impact:** - Python/Go sections now appear in CI benchmark output - Self-contained fixtures ensure consistent benchmarking - No dependency on RTK project structure Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(hooks): add missing RTK command rewrites Add 8 missing command rewrites to rtk-rewrite.sh and rtk-suggest.sh: - cargo check/install/fmt - tree, find, diff - head → rtk read (with --max-lines transformation) - wget Fixes BSD sed compatibility for head transformation by using literal spaces instead of \s+ (which doesn't work on macOS). Impact: ~18.2K tokens saved on previously missed commands discovered by `rtk discover`.

This file uses regex::Regex via fully-qualified paths (e.g., OnceLock<regex::Regex> / regex::Regex::new) instead of importing use regex::Regex;, which is the prevailing convention in this repo (e.g., src/utils.rs:9, src/runner.rs:3). Consider switching to an explicit import and using OnceLock<Regex> for consistency/readability.

PR title/description frame this primarily as a documentation update for existing Python/Go support, but this diff also introduces substantial new runtime functionality (new Rust modules/commands for ruff/pytest/pip/go/golangci-lint, parser changes, version bump). If that’s intended, consider updating the PR title/description to reflect that it’s a feature release as well (or split docs vs. behavior changes to ease review/risk).

golangci-lint exit code is currently ignored: run() always returns Ok(()) even when golangci-lint exits non-zero for reasons other than “issues found” (e.g., config errors, internal errors). This can cause CI to pass while linting actually failed. Consider explicitly checking output.status: treat exit code 1 as “issues found” (print filtered output but return Ok), but for any other non-success exit code propagate it (exit with code or return Err) and surface stderr regardless of verbosity.

filter_go_test_json only treats Action=="fail" as a failure when event.Test is present. In real go test -json output, build/package failures (and some package-level failures) are emitted as Action=="fail" events with no Test plus associated Output events with no Test. With the current logic those failures are ignored, so the summary can incorrectly print a success/no-tests message even though go test failed (run_test then exits non-zero, but the printed summary is misleading). Handle package-level fail events and non-test Output lines (e.g., track a package_failed flag and include build/output snippets in the failure summary).

| } |

current_test_output accumulates per-test output lines but entries are only removed on failed tests. For passing tests, collected output is never cleared, which can grow memory usage significantly on large test suites (especially with verbose output) even though that data is never displayed. Consider removing the buffer on Action=="pass" for a test, and/or only buffering output after seeing a failure marker.

In pip_cmd::run(), timer.track() uses base_cmd ("pip" vs "uv") to build the rtk command label: rtk {base_cmd} .... When uv is detected this will record the filtered invocation as rtk uv ..., but the user-facing command is still rtk pip .... Consider using a constant rtk pip ... label (and, if desired, include uv pip in the raw-command label only).

extract_json_object allocates a full Vec of the remaining input (input[start_pos..].chars().collect()), duplicating potentially large outputs in memory. This can be expensive for large JSON blobs (e.g., vitest testResults). Consider iterating over the slice with char_indices() (or bytes with careful string/escape handling) to brace-balance without allocating, and compute the end byte offset directly.
| let chars: Vec<char> = input[start_pos..].chars().collect(); | |
| for (i, &ch) in chars.iter().enumerate() { | |
| for (i, ch) in input[start_pos..].char_indices() { |
| // Force JSON output for check command | ||
| if !args.contains(&"--output-format".to_string()) { | ||

| } else { | ||
| cmd.arg("check"); | ||
| } |

Ruff JSON output flag detection only checks for an argument equal to "--output-format". If the user passes "--output-format=json" (or any "--output-format=..." form), this code will still inject another "--output-format=json", which can lead to duplicated/conflicting flags. Consider checking both the separate-arg and equals forms (e.g., a == "--output-format" || a.starts_with("--output-format=")).

Summary
Complete documentation update for RTK v0.15.1 Python and Go support across all documentation files.
Why: v0.15.0 added Python/Go commands but documentation was incomplete/outdated, causing confusion for Claude Code and users.
What: Comprehensive 4-phase update following strict validation checklist.
