patrick szymkowiak d0396da1ce chore: merge develop into master (#499)
* fix: handle tail rewrites with read tail-lines

* feat: add 32 TOML-filtered commands to hook rewrite rules (#475)

Add rewrite rules for all TOML-filtered commands so the Claude Code
hook automatically rewrites them to `rtk proxy <cmd>`. This ensures
TOML filters apply transparently without manual `rtk` prefixing.

Commands added: ansible-playbook, brew, composer, df, dotnet, du,
fail2ban-client, gcloud, hadolint, helm, iptables, make,
markdownlint, mix, mvn, ping, pio, poetry, pre-commit, ps, quarto,
rsync, shellcheck, shopify, sops, swift, systemctl, terraform, tofu,
trunk, uv, yamllint.

Tests updated to use `htop` as unsupported command example since
terraform is now supported via TOML filter.

* fix: git log --oneline no longer silently truncated to 10 entries (#461) (#478)

Only inject -10 limit when RTK applies its own compact format.
When user provides --oneline/--pretty/--format, respect git's
default behavior (no limit). Also detect -n and --max-count as
user-provided limit flags.

* fix: gh run view --job flag loses its value (#416) (#477)

Add --job and --attempt to flags_with_value in
extract_identifier_and_extra_args() so their values are not
mistaken for the run identifier when placed before it.

* fix: rtk read no longer corrupts JSON files with glob patterns (#464) (#479)

Add Language::Data variant for JSON, YAML, TOML, XML, Markdown, CSV
and other data formats. These files have no comment syntax, so the
MinimalFilter skips comment stripping entirely.

Previously, `packages/*` in package.json was treated as a block
comment start (`/*`), causing everything until the next `*/` to be
stripped — corrupting the JSON structure.

* fix: npm routing, discover cat redirect, proxy quoted args (#480)

* fix: npm routing, discover cat redirect, proxy quoted args (#470, #315, #388)

#470: rtk npm now correctly routes npm subcommands (install, list,
audit, etc.) without injecting "run". Previously, `rtk npm install`
was executed as `npm run install`.

#315: discover no longer counts `cat >`, `cat >>`, `cat |` as missed
savings. These are write/pipe operations with no terminal output to
compress.

#388: rtk proxy now auto-splits a single quoted argument containing
spaces. `rtk proxy 'head -50 file.php'` now works like
`rtk proxy head -50 file.php`.

* fix: proxy quote-aware split, redirect detection scan all tokens, npm test routing

- Proxy: replace split_whitespace with shell_split() that respects quotes (#388)
  e.g. 'git log --format="%H %s"' no longer splits on space inside quotes
- Discover: scan all tokens for redirect operators, not just nth(1) (#315)
  e.g. 'cat file.txt > output.txt' now correctly detected as write
- npm: replace tautological test with actual routing logic verification

* fix: use rtk <cmd> instead of rtk proxy for TOML-filtered commands (#507)

- Replace all 32 `rtk proxy <cmd>` rules with `rtk <cmd>` so TOML filters

- Extract NPM_SUBCOMMANDS to module-level const to prevent test/prod drift

* fix: respect user-specified git log limits instead of silently truncating

RTK was silently capping git log output in two ways:
1. `--oneline` without `-N` defaulted to 10 entries (now 50)
2. `filter_log_output()` re-truncated even when user explicitly set `-N`
3. Lines >80 chars were truncated, hiding PR numbers and author names

This matters for LLM workflows: Claude needs full commit history for
rebase, squash, and changelog operations. Silent truncation caused
incomplete context and repeated re-runs.

Changes:
- User-explicit `-N` → no line cap, wider 120-char truncation
- `--oneline`/`--pretty` without `-N` → default 50 (was 10)
- No flags → unchanged (default 10)
- Extract `truncate_line()` helper for clarity

Fixes #461

Integrate PR #172 by @danielmarbach onto develop:
- MSBuild binlog parser (binary format, gzip, 7-bit varint)
- TRX test result parser (quick-xml)
- Format report JSON parser
- Subcommand routing: build, test, restore, format + passthrough
- Sensitive env var scrubbing (GH_TOKEN, AWS_SECRET_ACCESS_KEY, etc.)
- Fallback to text parsing when binlog unavailable
- 86-93% token savings on real .NET projects

Maintainer fixes applied:
- Removed binlog temp path from output (wastes tokens)
- Dropped hook file changes (incompatible with develop architecture)
- Fixed unused variable warnings

888 tests pass.

* feat: TOML DSL PR 2 — user-global config, shadow warning, init templates, 4 new filters

- toml_filter: add ~/.config/rtk/filters.toml (priority 2, between project and built-in)
- toml_filter: shadow warning when match_command overlaps a Rust-handled command
- init: rtk init generates .rtk/filters.toml template (local) and ~/.config/rtk/filters.toml (global)
- builtin_filters: add pre-commit, helm, gcloud, ansible-playbook (46/46 inline tests)
- README: add "Custom Filters" section with lookup table, primitives, examples, built-in list

* feat(filters): add quarto-render, pnpm-build, trunk-build from rtk discover data (52/52 tests)

* feat(filters): add docker-inspect, sops, docker-compose-ps built-in filters

Resolves issues #279, #277, #276 as TOML-native filters (no Rust required).

- docker-inspect: strip_ansi + truncate_lines_at=120 + max_lines=60
- sops: strip_ansi + strip_lines_matching blank lines + max_lines=40
- docker-compose-ps: strip_ansi + truncate_lines_at=120 + max_lines=40

6 inline tests added (2 per filter), all passing.

* refactor(filters): split monolithic builtin_filters.toml into 28 individual files

Replace the 848-line src/builtin_filters.toml monolith with individual
files under src/filters/<name>.toml (1 filter + tests per file).

Files are concatenated alphabetically by build.rs at compile time into
OUT_DIR/builtin_filters.toml, then embedded via a BUILTIN_TOML constant
in toml_filter.rs. The build step validates TOML syntax and detects
duplicate filter names across files.

Benefits:
- Zero merge conflicts when multiple PRs add filters (different files)
- Clear PR diffs: "+1 file of 30 lines" vs "+30 lines in 850-line file"
- Easy onboarding: copy any .toml, rename, edit 3 fields — done
- Build-time TOML validation catches syntax errors before tests run

Changes:
- build.rs (new): concat + validate src/filters/*.toml
- Cargo.toml: add [build-dependencies] toml = "0.8"
- src/filters/*.toml (28 files): split from monolith
- src/filters/README.md (new): contributor guide
- src/toml_filter.rs: BUILTIN_TOML const + 5 include_str replacements
- src/builtin_filters.toml: deleted

* test(filters): add 5 new unit tests for multi-file architecture + wget filter

Unit tests added (toml_filter.rs):
- test_builtin_toml_has_schema_version: ensures build.rs injects schema_version
- test_builtin_all_expected_filters_present: guards against accidental file deletion
- test_builtin_filter_count: exact count check (fails if filter added/removed without update)
- test_builtin_all_filters_have_inline_tests: prevents shipping filters with no tests
- test_new_filter_discoverable_after_concat: simulates build.rs concat, verifies lookup

New built-in filter:
- src/filters/wget.toml: compact wget download output (strips connection/resolution
  noise, short-circuits on 'saved [' to 'ok (downloaded)', 2 inline tests)

Test results: 661/661 unit tests, 60/60 inline TOML filter tests

* fix: remove dead TOML filters — wget, git-checkout, git-merge, git-remote, cargo-run

These filters were never reachable: Clap routes rtk git/cargo commands
to their dedicated Rust modules before run_fallback is called. The TOML
engine only fires for unknown commands. Shipping dead filters gives false
confidence (inline tests pass, but filters never activate in production).

Also fixes P1-1 from the PR #386 review: wget was in RUST_HANDLED_COMMANDS
and the shadow warning fired at compile time but did not block the build.

Removed: cargo-run.toml, git-checkout.toml, git-merge.toml,
         git-remote.toml, wget.toml

Updated test guards: count 29→24, expected list -5 names,
concat test 30→25.

* fix: remove 3 dead TOML filters + update guards (PR #351)

docker-inspect, docker-compose-ps, and pnpm-build are handled by
container.rs and pnpm_cmd.rs before run_fallback is reached — their
TOML filters never fire. Remove the files to avoid false documentation.

Update toml_filter.rs guards: expected list -3 names, count 24→21,
concat test 25→22. Update CONTRIBUTING.md example count to match.

heAdz0r 606b86ed43 feat(gain): colored dashboard with efficiency meter and impact bars (#129)
* feat(gain): add colored dashboard with efficiency meter and impact bars

Upgrade `rtk gain` output with rich terminal visualization:
- Colored percentage cells (green ≥70%, yellow ≥40%, red <40%)
- Efficiency meter: ASCII progress bar with savings percentage
- Impact bars: proportional block charts per command
- Styled section headers (bold green)
- Command names in bright cyan
- History tier indicators (▲/■/•)
- Dynamic column widths for clean table alignment
- KPI-style key-value layout for summary metrics

All visual features are TTY-aware via std::io::IsTerminal — output
degrades gracefully to plain text when piped or redirected.

No new dependencies (uses existing `colored` crate).

Florian BRUNIAUX 00623cb80e docs: point all documentation to upstream instead of fork
## Problem
Documentation incorrectly promoted the fork over upstream for installation,
creating confusion about which repository is the source of truth.

## Changes

### Installation Instructions
- **README.md**: Restored curl install pointing to upstream (pszymkowiak/rtk)
- **README.md**: Removed "Fork with All Features" section
- **INSTALL.md**: Added curl install, removed fork recommendation
- **TROUBLESHOOTING.md**: All installation paths → upstream

### Repository References
- **README.md**: Removed fork from repo list, issues → rtk-ai/rtk
- **CLAUDE.md**: Removed fork mention from project list
- **CHANGELOG.md**: Repository and issues → rtk-ai/rtk
- **ROADMAP.md**: Installation instructions → upstream curl

### Scripts
- **check-installation.sh**: Install instructions → upstream curl

## Result
All documentation now consistently points to upstream (rtk-ai/rtk, pszymkowiak/rtk)
as the source of truth for installation and issues.

Florian BRUNIAUX e2e8be42a7 docs: clarify rtk name collision and fix installation confusion
## Problem
Users are accidentally installing the wrong "rtk" package:
- Rust Type Kit (reachingforthejack/rtk) - type generation tool
- Rust Token Killer (rtk-ai/rtk) - LLM token optimizer

This causes confusion when `rtk gain` doesn't exist after installation.

## Changes

### Documentation Updates
- **README.md**: Add prominent warning about name collision at top
- **README.md**: Fix installation instructions with mandatory verification
- **CLAUDE.md**: Add name collision warning with verification steps
- **INSTALL.md**: Clarify pre-installation checks and wrong package handling

### New Files
- **docs/TROUBLESHOOTING.md**: Comprehensive troubleshooting guide covering:
  - Wrong rtk installed (Type Kit vs Token Killer)
  - cargo install rtk pitfalls
  - Missing commands (vitest, pnpm, etc.)
  - PATH issues and compilation errors

- **scripts/check-installation.sh**: Automated diagnostic script that verifies:
  - RTK installed and in PATH
  - Correct version (Token Killer with `rtk gain`)
  - Available features
  - Claude Code integration status
  - Auto-rewrite hook configuration

## Verification
After these changes, users can quickly diagnose installation issues:
```bash
bash scripts/check-installation.sh
```

Fixes installation confusion reported by multiple users.

capabilities for in-depth token savings analysis and reporting.

New Features:
- Daily breakdown (--daily): Complete day-by-day statistics without 30-day limit
- Weekly breakdown (--weekly): Sunday-to-Saturday week aggregations with date ranges
- Monthly breakdown (--monthly): Calendar month aggregations (YYYY-MM format)
- Combined view (--all): All temporal breakdowns in single output
- JSON export (--format json): Structured data for APIs, dashboards, scripts
- CSV export (--format csv): Tabular data for Excel, Google Sheets, data science

Technical Implementation:
- src/tracking.rs: Add DayStats, WeekStats, MonthStats structures with Serialize
- src/tracking.rs: Implement get_all_days(), get_by_week(), get_by_month() SQL queries
- src/main.rs: Extend Commands::Gain with --daily, --weekly, --monthly, --all, --format flags
- src/gain.rs: Add print_daily_full(), print_weekly(), print_monthly() display functions
- src/gain.rs: Implement export_json() and export_csv() for data export

Documentation:
- docs/AUDIT_GUIDE.md: Comprehensive guide with examples, workflows, integrations
- README.md: Update Data section with new audit commands and export formats
- claudedocs/audit-feature-summary.md: Technical summary and implementation details

Database Scope:
- Global machine storage: ~/.local/share/rtk/history.db
- Shared across all projects, worktrees, and Claude sessions
- 90-day retention policy with automatic cleanup
- SQLite with indexed timestamp for fast aggregations

Use Cases:
- Trend analysis: identify daily/weekly patterns in token usage
- Cost reporting: monthly savings reports for budget tracking
- Data science: export CSV/JSON for pandas, R, Excel analysis
- Dashboards: integrate JSON export with Chart.js, D3.js, Grafana
- CI/CD: automated weekly/monthly savings reports via GitHub Actions

Examples:
  rtk gain --daily                    # Day-by-day breakdown
  rtk gain --weekly                   # Weekly aggregations
  rtk gain --all                      # All breakdowns combined
  rtk gain --all --format json | jq . # JSON export with jq
  rtk gain --all --format csv         # CSV for Excel/analysis

Backwards Compatibility:
- All existing flags (--graph, --history, --quota) preserved
- Default behavior unchanged (summary view)
- No database migration required
- Zero breaking changes

Performance:
- Efficient SQL aggregations with timestamp index
- No impact on rtk command execution speed
- Instant queries even with 90 days of data
