curl|bash one-liner stdin is not a TTY, so the upstream skills CLI
renders its interactive skill-picker TUI with nothing selected, exits
0, and installs zero skills — while our installer reports "done".
Pass --yes --all to skip the picker and confirmation prompts in both
the per-provider call and the auto-detect fallback.

- PR #372 (Dave): strip YAML fences from commands/caveman-init.toml — Gemini CLI's FileCommandLoader rejected the file with 'Failed to parse TOML' on extension install. Verified main was broken.
- PR #350 intent (David): rename codex_hooks → hooks in .codex/config.toml. Codex source confirms canonical key is now 'hooks'; codex_hooks is a legacy alias that emits a deprecation log.
Closes#372#326 (duplicate) #350 locally — push deferred.
Codex's CodexHooks feature now exposes key 'hooks' (Stable). codex_hooks
kept as legacy alias in codex-rs/features/src/legacy.rs but emits a
deprecation log. Match the canonical name.
Verified against openai/codex codex-rs/features/src/lib.rs:

Two bugs at the curl|bash entry point made the headline install command
fail immediately:
1. install.sh used `${BASH_SOURCE[0]}` under `set -u`. That variable is
unset when bash is invoked from stdin (curl | bash), tripping the
nounset trap before we ever reached the npx fallback.
2. install.sh + install.ps1 passed `--` between npx and the package args.
On modern npm, npx forwards the literal `--` to bin/install.js, which
parseArgs rejected as an unknown flag.
Fix:
- install.sh: default BASH_SOURCE[0] to empty so the curl-pipe path falls
through cleanly under set -u.
- install.sh + install.ps1: drop the `--` separator. npm 7+ npx already
forwards trailing args correctly.
- bin/install.js parseArgs: accept a bare `--` as a no-op (POSIX
end-of-options marker) so future shim drift can't re-break this.
- New regression test asserts `--` is accepted.

Refactor and harden the unified Node installer and related docs. Major changes:
- bin/install.js: validate --only ids, expand ~ for --config-dir, make Claude/install flows async (await hooks/init), add many CLI flags (--no-mcp-shrink, --with-hooks/--no-hooks, --skip-skills, --config-dir docs), preserve original backups once, avoid overwriting plugin/command files unless --force, and add opencode AGENTS.md fenced begin/end markers so installs/uninstalls can append/strip cleanly. Also add opencode idempotency probes for claude/gemini uninstall paths and better handling of opencode plugin payload.
- bin/lib/settings.js: safer removeCavemanHooks that validates shapes before mutating hooks.
- runInit/installHooks/downloadTo calls made async and awaited; runInit returns promise now.
- Docs and README/INSTALL/CONTRIBUTING/CLAUDE.md/src/hooks/README.md: update user-facing text to match new flags/behaviour, standardize use of $CLAUDE_CONFIG_DIR, clarify --with-init semantics, and note opencode/openclaw handling. Change command name usages from `/caveman:compress` to `/caveman-compress`.
- opencode: write fenced caveman block to AGENTS.md and handle legacy unfenced blocks; tests updated to expect fence markers.
These changes improve idempotency, safer upgrades/uninstalls, clearer UX around per-repo vs per-user init, and make the opencode rule block removable without destroying user content.
OpenClaw is a self-hosted gateway that orchestrates multiple agents and
loads workspace skills on-demand. To make caveman always-on through it we
write a spec-correct skill folder plus a marker-fenced bootstrap block in
SOUL.md (which OpenClaw auto-injects every turn). Both writes are
idempotent and reachable from `bin/install.js --only openclaw` and
`caveman-init.js --only openclaw`. Side-effect: `--only <id>` now bypasses
the detect-match guard so explicit opt-in works for any provider whose
preconditions can't be probed (e.g. custom OPENCLAW_WORKSPACE paths).

Replaces opencode's Tier-4 npx-skills entry with a native in-repo plugin
that mirrors the Claude Code hook architecture (session.created +
tui.prompt.append) using opencode's lifecycle hook system. Reaches Tier-1
parity minus the statusline (opencode TUI exposes no plugin-writable
badge). Skill files drop in unchanged — opencode reads SKILL.md natively.
Plugin reuses src/hooks/caveman-config.js for the symlink-safe flag-write
helpers via createRequire (renamed .cjs post-install to coexist with the
plugin dir's "type":"module"). AGENTS.md provides a Tier-3 always-on
fallback if the plugin runtime breaks.
5 new tests cover fresh install, idempotency, JSONC tolerance of
pre-existing opencode.json, uninstall, and a plugin smoke test that fires
synthetic tui.prompt.append events. All 38 installer tests pass.

Brings the long-stashed Node installer onto main. install.sh and install.ps1
shrink to thin shims (~50 lines each) that delegate to bin/install.js, fixing
the cross-platform drift that caused #249-class quoting bugs.
- bin/install.js (850 lines) — unified PROVIDERS-driven installer
- bin/lib/settings.js (221 lines) — JSONC parser + hook validator
(validateHookFields prevents single bad hook from poisoning settings.json)
- tests/installer/{unit.argv,unit.settings,e2e.dryrun}.test.mjs — npm test
now actually runs four real tests (was silently passing 0)
- .agents/skills/cavecrew, .junie/, .kiro/, .roo/ — per-agent skill mirrors
- skills-lock.json — vercel-labs/skills slug pinning
- install.{sh,ps1}.legacy escape hatch dropped (git history is the fallback)
- Minor cavecrew agent description refinements
Closes the gap between docs (already merged) describing bin/install.js and
the actual implementation.
Reflect the post-cleanup repo layout: consolidated caveman-compress
under skills/, removed agent-dotdir mirrors, build artifacts in dist/,
per-skill READMEs alongside SKILL.md, bin/install.js as the only
installer entry point, and INSTALL.md for the per-agent reference.
Adds a top-level "What lives where" tree, trims the auto-synced table
to what CI actually mirrors, and updates the key rules accordingly.

Real install harness — writes hooks, merges settings.json, asserts on-disk
state. Catches regressions a dry-run can't see (missing hooks, malformed
settings, broken statusline). Five cases:
- Fresh install populates hooks dir + wires SessionStart/UserPromptSubmit
- Idempotent install does not duplicate hook entries
- Uninstall strips caveman hooks, preserves user-authored ones
- Install tolerates JSONC settings.json (#249 regression guard)
- Lib-level addCommandHook idempotency (always runs, no claude CLI)
Tests requiring `claude` on PATH skip cleanly with a clear reason. Uninstall
test strips claude/gemini from PATH so the user's real plugin/extension
state is never touched.

Trim README from 16.4 KB to 10.2 KB (~38% shorter, 331 -> 220 lines)
so non-technical readers can scan it in 60 seconds. Front door now
keeps the Before/After pitch, one-line install, top-6 manual install
table, condensed feature matrix, real benchmark numbers, and a short
"how it work" section in caveman voice.
Moves to other docs:
- Full 30+ agent install matrix and detailed flag reference -> INSTALL.md
- Hook architecture deep-dive -> CLAUDE.md (already there)
- Eval methodology paragraphs -> evals/ link
Caveman voice phrases preserved ("Brain still big", "Cost go down
forever", "One rock. Two rock. Three rock. That it.", "caveman speak").
Benchmark numbers untouched (verbatim from benchmarks/results/). All
top-of-funnel install commands still work.

Drop CI-generated mirrors that self-applied caveman to this repo when
opened in Cursor/Windsurf/Cline/Copilot. The installer never read them
(bin/install.js consumes only hooks/, rules/, tools/, agents/, skills/,
mcp-servers/, plugins/caveman/), so removing them just declutters the
root. Devs who want self-application can opt in via npx caveman --only
<agent>.
Removed:
- .cursor/skills/, .cursor/rules/caveman.mdc
- .windsurf/skills/, .windsurf/rules/caveman.md
- .clinerules/caveman.md
- .github/copilot-instructions.md
- caveman/SKILL.md (and empty caveman/ parent)
Updated .github/workflows/sync-skill.yml: drop the cp + mkdir lines and
git add paths for those mirrors, drop the entire "Sync auto-activation
rules" step, and drop rules/caveman-activate.md from the paths: trigger
since the workflow no longer consumes it. plugins/caveman/, cavecrew,
compress, and caveman.skill ZIP sync steps are preserved.
Updated CONTRIBUTING.md note to reflect the smaller auto-synced set.

- Move caveman-compress/ source (SKILL.md, scripts/, README.md, SECURITY.md) to skills/caveman-compress/.
- Delete skills/compress/ — the CI-generated rename mirror that caused dual-source confusion.
- Move plugins/caveman/skills/compress/ to plugins/caveman/skills/caveman-compress/. Plugin keeps the consolidated name; CI no longer rewrites the frontmatter.
- Replace the two sed-heavy CI sync steps with one verbatim cp -r from source to plugin.
- Update verify_repo.py, test_compress_safety.py, test_validate_inline.py, GEMINI.md, AGENTS.md, CONTRIBUTING.md, README.md, and the workflow paths to reference the new location.
- Use Path.resolve().parents[N] for the benchmark.py repo-root walk now that the directory depth changed.

Expand the 25-line stub to a scannable 190-line guide reflecting the
post-cleanup repo layout. Adds:
- Sources-of-truth table covering all editable skill, agent, hook, and
installer files (skills/caveman-compress/, bin/install.js PROVIDERS,
tools/caveman-init.js, mcp-servers/caveman-shrink/).
- CI-mirrors table calling out plugins/caveman/* and dist/caveman.skill
as auto-rebuilt, edits-will-be-reverted.
- Step-by-step recipes for adding a new agent (PROVIDERS row +
--list verification) and a new skill (frontmatter + sync workflow).
- Test commands (npm test, compress safety, init, symlink), benchmark
and eval invocations, PR guidelines, and the load-bearing code-style
invariants (silent-fail hooks, JSONC-tolerant settings.js,
safeWriteFlag, CLAUDE_CONFIG_DIR).

The caveman.skill ZIP is regenerated by CI on every push and lived at
the repo root, where users mistook it for an editable source. Moving it
to dist/ makes its build-product nature obvious while keeping it
tracked so GitHub release links and npm packaging keep working.
Updates:
- git mv caveman.skill -> dist/caveman.skill
- .github/workflows/sync-skill.yml rebuild step now writes to dist/
- .gitignore ignores dist/* but allows dist/caveman.skill
- package.json files array includes dist/caveman.skill for npm pack
- CONTRIBUTING.md and tests/verify_repo.py path references updated

Add a human-facing README.md to each skill directory so users browsing
skills/ can quickly see what each skill does, how to invoke it, and an
example output. Mirrors the per-skill README pattern used by upstream

SKILL.md remains the LLM-facing system prompt; README.md is the human
front door.

CLAUDE.original.md was a backup snapshot from the initial caveman-compress
of the project's own CLAUDE.md. It is not referenced by any tooling — the
mentions in caveman-compress/README.md and tests/test_caveman_stats.js
describe the compress skill's output naming convention, not this file.
The other deletion targets from the cleanup brief (install.sh.legacy,
install.ps1.legacy, .junie/, .kiro/, .roo/, .agents/) either don't exist
in this branch or — in the case of .agents/plugins/marketplace.json — are
real manifests verified by tests/verify_repo.py.

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/.

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.

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.

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.

Two converging hook fixes:
* /caveman arg parser uses VALID_MODES whitelist (#314 by @jgttech).
Drops the silent fallback to getDefaultMode() on unknown args. Three
bugs collapsed: /caveman full was impossible if defaultMode was set
to anything else, /caveman off had no effect, and typos like
/caveman fulll silently clobbered state. Now: bare /caveman activates
default; /caveman off|stop|disable removes flag; unknown args leave
flag untouched (no silent overwrite); independent modes (commit,
review, compress) cannot be selected as args.
* safeWriteFlag through symlinked ~/.claude (#224 by @voidborne-d,
closes#207). Earlier hardening (5ad8f6d) refused every symlinked
parent including legitimate ~/.claude → /opt/shared-claude or
/mnt/d/claude-config patterns. Now resolves the parent via
realpathSync, verifies ownership on Unix (uid match) or under-home
on Windows, and uses the resolved path for the atomic write. Flag
file itself still must not be a symlink — that's the actual clobber
vector. CAVEMAN_DEBUG=1 emits stderr diagnostics on refusal.
12 regression tests in tests/test_symlink_flag.js — all pass.
Verified:
/caveman / lite / full / ultra / wenyan{,-lite,-full,-ultra} → mode set
/caveman off / stop / disable → flag deleted
/caveman commit → no flag (rejected)
/caveman fulll (typo) → no flag (rejected)
symlink ~/.claude → owned dir → write succeeds in real dir
symlink ~/.claude → other-user dir → refused

PowerShell 5.1 mangles the multiline $nodeScript when passed to

early, causing SyntaxError mid-install. Hook files copy but
settings.json never updates, leaving caveman non-functional.
Write the script to %TEMP%\caveman-install-<pid>.js, run it, clean

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.

Parent-chain walk produced false positives: macOS /tmp -> /private/tmp
and symlinked home dirs broke all flag writes. Check only the immediate
parent directory and the target itself — that covers the threat model
(attacker replacing the flag with a symlink) without breaking legit
paths.
Extend safeWriteFlag() in caveman-config.js with:
- hasSymlinkInPath() walks every ancestor component and refuses
if any is a symlink (protects against parent-dir redirect)
- Atomic write via temp file + rename
- O_EXCL on temp open to prevent race
Removes duplicate local helper from mode-tracker.
