caveman-shrink@0.1.0 is now live on npm (pre-1.0). Restore the original
default-on behavior for --with-mcp-shrink / -WithMcpShrink. Keep the
`npm view caveman-shrink` probe — a transient registry outage now degrades
to a clean manual-config skip instead of registering a `npx -y caveman-shrink`
entry that would have spawned-failed.
Also: sync `model: haiku` onto cavecrew investigator/reviewer canonicals
so the top-level agents/ matches the synced plugins/caveman/agents/.
README + CLAUDE.md flipped back to "On by default."

install.sh:
- detect_match: replace `awk -v RS='||'` (rejected by macOS BSD awk:
"illegal primary in regular expression") with bash parameter expansion.
Compound detection specs were silently failing, so cursor / windsurf /
continue / and 28 other compound-spec providers were never detected.
- --with-mcp-shrink: flip default OFF + probe `npm view caveman-shrink`
before registering. Was registering a config that 404s on first spawn.
install.ps1: mirror the MCP-shrink default flip + npm probe.
tests: update statusline tests for default-on suffix behavior. Add a
regression for fresh installs where the suffix file is absent.
Add npm-pkg-fix formatting to package.json.
cavecrew: promote agents/cavecrew-*.md to top-level canonical, refine
subagent contracts (sharper output formats, terminal refusal
lines, model: haiku for read-only roles). CI workflow syncs
agents/ + skills/cavecrew/ into plugins/caveman/.
docs: README & CLAUDE.md align with new opt-in MCP-shrink policy.

- caveman-stats: dollar math via per-million model pricing, --share
tweetable line, lifetime log via symlink-safe appendFlag, --all and
--since N[d|h] aggregation, opt-in statusline savings suffix, and
detection of *.original.md compress backups for input-side savings.
- install.sh / install.ps1 at repo root: smart multi-agent installer
that detects Claude Code, Gemini, Codex, Cursor, Windsurf, Cline,
Copilot and runs each one's native install. Idempotent, --dry-run,
--only, --force.
- cavecrew: skills/cavecrew + three Claude Code subagents
(investigator / builder / reviewer) for caveman-style machine-to-
machine handoffs.
- cavepack: tools/caveman-init.js drops the always-on caveman rule
into Cursor / Windsurf / Cline / Copilot / AGENTS.md in one shot,
idempotent, with a sentinel check so re-runs never duplicate.
- caveman-shrink: MCP middleware proxy + pure-Node prose compressor
that strips articles/filler/hedging from tools/list descriptions
while preserving code, URLs, paths, and identifiers byte-for-byte.
59 tests passing (27 stats, 8 init, 12 mcp-shrink, 12 symlink-flag).

New slash command that reads the active Claude Code session JSONL
(.claude/projects/**/*.jsonl), sums output_tokens and
cache_read_input_tokens from assistant turns, and shows an estimated
savings figure when the active mode is 'full'.
Real numbers, not the model's guess:
Caveman Stats
──────────────────────────────────
Session: ...projects/my-app/abc123.jsonl
Turns: 47
──────────────────────────────────
Output tokens: 3,210
Cache-read tokens: 128,400
──────────────────────────────────
Est. without caveman: 9,171
Est. tokens saved: 5,961 (~65%)
Savings est. from benchmarks/ (mean per-task). Actual varies by task.
Implementation:
* hooks/caveman-stats.js — script. Run directly with
`node hooks/caveman-stats.js`, or via `--session-file <path>`.
Falls back to most-recent JSONL under .claude/projects/ when no
session file is passed.
* hooks/caveman-mode-tracker.js — `/caveman-stats` triggers an
execFileSync call to caveman-stats.js with the hook's transcript_path,
and the output is returned via `decision: "block"` so the user sees
the stats inline without a model round-trip.
* install.sh / install.ps1 / uninstall.{sh,ps1} include
caveman-stats.js in HOOK_FILES.
* skills/caveman-stats/SKILL.md (+ plugin mirror) for skill listing.
* README install matrix and Caveman Skills section updated.
Compression ratio (0.65) is the mean per-task figure from
benchmarks/results/*.json (avg_savings: 65 across 10 tasks). Only 'full'
mode has measured data — lite/ultra/wenyan show no estimate.
Tests: 6 passing in tests/test_caveman_stats.js covering direct
invocation, full-mode estimate math, non-full skip, no-session error,
mode-tracker block behavior, and flag preservation.
Closes#305 (re-implementation; takes the design from
@DeeptimaanB but rewritten against current main).

Three small SKILL.md edits batched:
* Ultra mode: spell out that abbreviation applies to prose only, never to
code symbols, function names, API names, or error strings (#238 by
@AnthoHansen). Stops models from rendering literal `fn` in code where
the user wrote `function`.
* Auto-clarity (#239 by @AnthoHansen): bullet list replaces run-on
sentence; adds explicit trigger for compression-induced ambiguity in
technical sequences (e.g. "migrate table drop column backup first").
* Typst + LaTeX (#243 by @wildwestrom): add .typ, .typst, .tex to
COMPRESSIBLE_EXTENSIONS in caveman-compress/scripts/detect.py and to
the boundaries lists in SKILL.md / README.md.
Synced SKILL.md to caveman/, plugins/caveman/skills/caveman/,
.cursor/skills/caveman/, .windsurf/skills/caveman/, and rebuilt
caveman.skill ZIP.

Five user-contributed fixes consolidated:
* UTF-8 stdout (#289 by @ousamabenyounes) — reconfigure stdout/stderr at the
top of cli.py so Windows cp1252 consoles don't crash on the ❌ glyph in
error/validation branches and mask the real error.
* Empty / unchanged compression guards (#292 by @ousamabenyounes, closes#237)
— refuse empty input, refuse empty/whitespace/identical Claude output,
read back the backup before touching the input. Five regression tests in
tests/test_compress_safety.py.
* Inline backtick validation (#309 by @hireblackout) — validate_inline_codes
closes the silent-overwrite gap where `npm install` → `yarn install`
passed validation. Wired into validate(); 11 unit tests in
tests/test_validate_inline.py.
* Frontmatter angle-bracket fix (#268 by @Bortlesboat, closes#266) —
caveman-compress/SKILL.md description now uses FILEPATH instead of
<filepath>, plus verify_repo gains a new
verify_skill_frontmatter_upload_compatibility check, UTF-8 hardening for
Windows, and the activation-banner regex no longer requires a trailing
period.
* Two test fixtures (claude-md-project.md, mixed-with-code.md) updated so
the new inline-backtick validator passes — they were silently dropping
`server/src/`, `type(scope): description`, and `status` references in
compression. The fixture is documentation of "good" compression, so the
fix is to preserve those references.

Writes were hardened via safeWriteFlag (PRs #70/#71) but readers still
trusted whatever the flag contained. A local attacker with write access
to ~/.claude/ could symlink the flag at a secret file and have the
per-turn reinforcement inject its bytes into model context, or the
statuslines echo ANSI escapes to the terminal on every keystroke.
- caveman-config.js: new readFlag() — lstat symlink refuse, 64-byte cap,
O_NOFOLLOW, VALID_MODES whitelist. Returns null on any anomaly.
- caveman-mode-tracker.js: per-turn reinforcement routes through
readFlag() instead of fs.readFileSync.
- caveman-statusline.sh / .ps1: symlink + size refuse, strip to
[a-z0-9-], whitelist-validate before rendering.
- compress.py (3 synced copies): is_sensitive_path() denylist refuses
.env*, .netrc, keys/certs, ~/.ssh|.aws|.gnupg|.kube|.docker, and any
basename containing secret/credential/password/apikey/token/privatekey
(separator-insensitive). Fails loudly before read — no silent exfil
of credentials to the Anthropic API.

Symlinks in plugins/caveman/skills/compress/ were checked out as plain
text path stubs on Windows (core.symlinks=false), causing Codex to reject
SKILL.md as missing YAML frontmatter. Replace with verbatim copies of
source files and add CI sync step to keep them in sync.

Separate language translations are unnecessary — Claude already responds
in the user's language. These added maintenance surface without real value.
Wenyan mode is kept as it's a genuinely different compression technique
built into the core skill.

- Update caveman-compress/SKILL.md name to 'compress' and trigger to '/caveman:compress'
- Create symlinks from compress/ (Claude Code) and plugins/caveman/skills/compress/ (Codex/npx) to caveman-compress/
- Single source of truth: caveman-compress/ holds all scripts and SKILL.md
- Update README to reflect compress as built-in skill
Fixes#33
- Add intensity levels section to README so feature is discoverable
- Document Codex trigger syntax ($caveman lite|full|ultra) in SKILL.md
- Sync plugin copy and rebuild .skill archive

Adds three compression levels so users can dial caveman up or down:
- Lite: drops filler/pleasantries, keeps normal grammar
- Full: existing default behavior, unchanged
- Ultra: maximum telegraphic compression with abbreviations
Closes#10
