refactor(skills): dedup compress -> caveman-compress [v1.0.0]

skills/compress/ was a byte-identical dupe of skills/caveman-compress/
(SHA256 match across all 7 scripts/ files; SKILL.md diff was name: +
Process step 2 only; descriptions textually identical = arbitrary
harness tie-break + double-counted listing budget).

Kept caveman-compress canonical: it carries README.md (benchmarks +
caveman-toolkit branding) and SECURITY.md (Snyk false-positive writeup),
and matches the caveman-* prefix invariant.

Ported the better Process-step wording from compress
(`cd <directory_containing_this_SKILL.md>`) into caveman-compress;
the prior `cd caveman-compress` form assumed cwd was the parent dir
and broke when invoked from ~/.claude/skills/caveman-compress/.

Added version: 1.0.0 to caveman-compress frontmatter
(first versioned release; aligns with skill-versioning concept).

Removed: skills/compress/, dist/compress.skill,
~/.claude/skills/compress/ (manual prune; install.sh has no prune step
yet -- future [install-ps1] task should add --prune).

Slash-command impact: /compress gone; /caveman-compress and
/caveman:compress (toolkit-canonical) remain.

Wiki: .wiki/concepts/compress-dedup.md (rationale + rejected
alternatives), index.md + log.md updated.

Tasks: [compress-dedup] flipped active -> done in same commit
(per-task file .tasks/compress-dedup.md created with full decisions
log).

## [compress-dedup] — resolve compress vs caveman-compress duplication
**Status:** ready
**Where I stopped:** (not started) — noticed during initial migration that both skills ship identical `scripts/` subtrees (`compress.py`, `cli.py`, `detect.py`, `validate.py`, `benchmark.py`)
**Next action:** `diff -r skills/compress skills/caveman-compress`; decide if one is canonical and the other should be removed (or aliased)

## 🟢 [compress-dedup] — resolve compress vs caveman-compress duplication
**Status:** done
**Where I stopped:** `skills/compress/` deleted as a byte-identical dupe of `skills/caveman-compress/` (SHA256 match across all 7 scripts/ files; SKILL.md diff was `name:` + Process step 2 only; README + SECURITY only in caveman-compress). Ported the better Process-step wording from compress (`cd <directory_containing_this_SKILL.md>` instead of brittle `cd caveman-compress`) into `skills/caveman-compress/SKILL.md`. Added `version: 1.0.0` to caveman-compress frontmatter (first versioned release; aligns with skill-versioning concept). Removed: `skills/compress/`, `dist/compress.skill`, `~/.claude/skills/compress/` (manual prune — install.sh has no prune step). Rebuilt `dist/caveman-compress.skill` + reinstalled to `~/.claude/skills/caveman-compress/` (verified `version: 1.0.0` + new Process step on disk). Harness skill listing confirms `compress` is gone, only `caveman-compress` remains. `.wiki/concepts/compress-dedup.md` written (rationale + rejected alternatives: alias-stub has no harness mechanism, "keep both" wastes listing budget, "delete caveman-compress" loses README + SECURITY); `.wiki/index.md` + `.wiki/log.md` updated.
**Next action:** (none — kept until merged)
**Branch:** master

# compress-dedup
## Goal
Resolve the duplication between `skills/compress/` and `skills/caveman-compress/`. Both ship byte-identical `scripts/` (7 files: `__init__.py`, `__main__.py`, `benchmark.py`, `cli.py`, `compress.py`, `detect.py`, `validate.py`) and near-identical `SKILL.md` (only `name:` field and Process step 2 differ). Both register independently with the harness with identical descriptions — listing-token waste and arbitrary tie-break on activation. Pick canonical = `caveman-compress` (richer: README + SECURITY + caveman-toolkit branding); port the better Process-step wording from `compress` (generic `cd <directory_containing_this_SKILL.md>` vs brittle `cd caveman-compress`); delete `skills/compress/` entirely. Add `version: 1.0.0` frontmatter to caveman-compress (project-discipline Rule 3 alignment). Skill listing collapses from two redundant entries to one rich one. Install path `~/.claude/skills/compress/` is removed.
## Key files
- `skills/compress/` — entire folder deleted
- `skills/caveman-compress/SKILL.md` — port Process step from compress; add `version: 1.0.0`
- `skills/caveman-compress/README.md` — left as-is (already canonical, branding intact)
- `skills/caveman-compress/SECURITY.md` — left as-is
- `dist/compress.skill` — deleted (rebuild won't recreate; source gone)
- `dist/caveman-compress.skill` — rebuilt after SKILL.md edit
- `~/.claude/skills/compress/` — removed manually (install.sh has no prune step)
- `~/.claude/skills/caveman-compress/` — reinstalled
- `.wiki/concepts/compress-dedup.md` — design rationale (why caveman-compress canonical, why no alias mechanism, install-path impact)
- `.wiki/index.md` — add concept entry
- `.wiki/log.md` — append decision line
- `.tasks/STATUS.md` — flip compress-dedup ⚪ → 🔴 → 🟢
## Decisions log
- 2026-05-05: scripts/ byte-identical (SHA256 match across all 7 files). SKILL.md diff = `name:` field + Process step 2 only. Description text identical between the two. README + SECURITY only in caveman-compress. Conclusion: same skill, two registrations.
- 2026-05-05: chose `caveman-compress` as canonical over `compress`. Rationale: (a) richer docs (README with benchmarks table, branding, "Part of Caveman" toolkit linkage; SECURITY.md with Snyk false-positive writeup), (b) name reflects actual upstream origin (JuliusBrussee/caveman toolkit), (c) caveman cluster (caveman, caveman-commit, caveman-review, caveman-help, caveman-compress) has consistent prefix.
- 2026-05-05: rejected "alias-stub" approach (keep `compress` as a tiny SKILL.md pointing at caveman-compress). Harness has no alias mechanism — every SKILL.md fully registers; alias-stub still consumes a listing slot and a description budget. No win.
- 2026-05-05: rejected "keep both" approach. Identical descriptions ⇒ harness arbitrarily tie-breaks; both consume listing tokens; user has no way to predict which fires. Pure waste.
- 2026-05-05: ported Process step 2 wording from `compress` SKILL.md into `caveman-compress` SKILL.md. The compress version (`cd <directory_containing_this_SKILL.md> && python3 -m scripts ...`) is robust regardless of cwd; the caveman-compress version (`cd caveman-compress && ...`) implicitly assumes cwd is the parent directory. Net: caveman-compress gets the better text + keeps everything else.
- 2026-05-05: added `version: 1.0.0` frontmatter to caveman-compress SKILL.md. First versioned release of this skill. Aligns with the rest of the infra-skill cluster (skill-versioning concept).
- 2026-05-05: install.sh has no prune step — removing `skills/compress/` does NOT remove `~/.claude/skills/compress/`. Manual `rm -rf ~/.claude/skills/compress/` required. Filed mental note for `[install-ps1]` task: future installer should accept a `--prune` flag, or `setup-tasks`-style canon-list, to remove stale installs.
- 2026-05-05: slash-command impact — `/compress` slash command stops working after deletion; `/caveman-compress` and `/caveman:compress` (the canonical caveman-toolkit form) remain. Confirmed with user that `/compress` was effectively never used; no migration needed.
## Open questions
- [ ] Eventually wire up an `install.sh --prune` flag that drops `~/.claude/skills/<name>/` for any name not in `skills/<name>/`. Tracked indirectly via `[install-ps1]` ⚪ task — that task should at minimum match install.sh, but adding prune is the right time to do it.
## Completed steps
- (filled in during implementation)
## Notes
- Origin: both skills came from the JuliusBrussee/caveman upstream toolkit (caveman-compress carries the "Part of Caveman" branding); `skills/compress/` looks like a stripped-down copy that lost README + SECURITY + branding. Never reconciled until this task.
- Frontmatter description budget reminder (~900 chars): caveman-compress description is well under, no risk on this edit.

# compress vs caveman-compress dedup
> Two skills shipped the same payload under different names. Kept `caveman-compress` (richer, on-brand), deleted `compress`. Recorded here so future readers don't reinvent the analysis.
## What we found
Side-by-side audit of `skills/compress/` and `skills/caveman-compress/`:
| Layer | `compress` | `caveman-compress` |
|---|---|---|
| `scripts/__init__.py` | identical (SHA256) | same |
| `scripts/__main__.py` | identical | same |
| `scripts/benchmark.py` | identical | same |
| `scripts/cli.py` | identical | same |
| `scripts/compress.py` | identical | same |
| `scripts/detect.py` | identical | same |
| `scripts/validate.py` | identical | same |
| `SKILL.md` description | byte-identical text | byte-identical text |
| `SKILL.md` Process step 2 | `cd <directory_containing_this_SKILL.md> && python3 -m scripts ...` (generic) | `cd caveman-compress && python3 -m scripts ...` (brittle, assumes cwd is parent) |
| `SKILL.md` `name:` | `compress` | `caveman-compress` |
| `README.md` | absent | present (benchmarks table, branding, "Part of Caveman" toolkit linkage) |
| `SECURITY.md` | absent | present (Snyk false-positive writeup: subprocess + file I/O patterns explained) |
| Frontmatter `version:` | absent | absent (added `1.0.0` as part of this dedup) |
Description text in both skills' frontmatter:
```
Compress natural language memory files (CLAUDE.md, todos, preferences) into caveman format
to save input tokens. ... Trigger: /caveman:compress <filepath> or "compress memory file"
```
— literally the same paragraph. The harness loads both skill listings, both register independently, descriptions identical ⇒ activation tie-break is arbitrary, and the listing budget pays twice.
## What we kept and why
**Canonical = `caveman-compress`.** Reasons in order of weight:
1. **Richer artefacts** — README.md and SECURITY.md exist only here. The README is not boilerplate: benchmarks table on real files (claude-md-preferences.md, project-notes.md, mixed-with-code.md), 46% average savings claim, before/after example. The SECURITY.md is what static-analysis (Snyk) hooks into, so deleting it would re-open the same false-positive ticket the upstream author already closed.
2. **On-brand naming** — the skill is part of the [JuliusBrussee/caveman](https://github.com/JuliusBrussee/caveman) toolkit. The `caveman-*` prefix lines up with the rest of the cluster: `caveman` (speak compressed), `caveman-commit` (commit-message variant), `caveman-review` (PR-review variant), `caveman-help` (help card), `caveman-compress` (compress files). `compress` was the lone exception that broke the prefix invariant.
3. **History reads cleanly** — the per-task `[skill-readmes]` plan groups the caveman cluster as a single batch for README work. Keeping the prefix means that batch covers all of them; mixing in a stray `compress` would force a "wait, do we README this one separately?" decision later.
## What we ported across before deleting
The only thing `compress` did better than `caveman-compress` was Process step 2. Original wording:
```
cd caveman-compress && python3 -m scripts <absolute_filepath>
```
This assumes cwd is the parent of `caveman-compress/`. When the agent invokes the skill from `~/.claude/skills/caveman-compress/`, that assumption is false (cwd is the skills dir, parent is `~/.claude/`). The `compress` SKILL.md had the robust form:
```
cd <directory_containing_this_SKILL.md> && python3 -m scripts <absolute_filepath>
```
— ported into `caveman-compress/SKILL.md` as part of this dedup. Net: the canonical skill now has the better instructions plus the README + SECURITY.
Also added `version: 1.0.0` to frontmatter — first versioned release. Aligns with the rest of the infra-skill cluster ([skill-versioning](skill-versioning.md)).
## What we rejected
**Alias-stub** — keep `skills/compress/SKILL.md` as a tiny pointer file with description "alias for caveman-compress, see that skill". Rejected: the harness has no alias mechanism. Every SKILL.md file fully registers as a skill, with its description text consuming the listing budget. An alias-stub still occupies a listing slot and a description allowance — there's no "see that skill" indirection at the harness level. Pure waste of a listing entry.
**Keep both, document them as siblings** — let the user pick which slash-command name they prefer (`/compress` vs `/caveman-compress`). Rejected: descriptions are identical; the harness has no signal to disambiguate; activation tie-break is arbitrary. Forces every future `/caveman:compress` call to gamble on which copy the harness picks.
**Delete `caveman-compress`, keep `compress` as the simpler name** — rejected because we'd lose the README, SECURITY.md, and the caveman-toolkit branding link. `compress` was the stripped-down fork; reverting to it would be a net regression in artefact quality.
## Install-path impact
`scripts/install.sh` has no prune step. Removing `skills/compress/` does **not** remove `~/.claude/skills/compress/` on the user's machine — the install script copies, never deletes. Manual `rm -rf ~/.claude/skills/compress/` is required during this dedup. Same applies to `dist/compress.skill`: deleted explicitly, since the next `build.sh` run iterates over `skills/<name>/` and won't recreate an artefact for a source folder that no longer exists.
> **Future work:** the [`install-ps1`](../../.tasks/STATUS.md) ⚪ task should at minimum match `install.sh`'s behavior, but is also the right time to add a `--prune` flag that removes `~/.claude/skills/<name>/` for every name not in `skills/<name>/`. Would have made this dedup automatic instead of three-step.
## Slash-command impact
Before: `/compress`, `/caveman-compress`, and `/caveman:compress` (toolkit-canonical) were all live.
After: `/compress` is gone. `/caveman-compress` and `/caveman:compress` still work. User confirmed `/compress` was effectively never used; no migration needed.

Map embedded in SKILL.md (9 rows: caveman, superpowers plugin, using-wiki, using-tasks, using-projects-meta, pulling-before-work, project-discipline, using-interns, active-platform); `kind: skill` vs `kind: plugin` flag drives the install command emitted in the recommendation block. Algorithm: read project's CLAUDE.md → match each line vs map (substring + tolower, mirrors Step 5 idempotent merge) → for each canonical match check disk (`~/.claude/skills/<name>/SKILL.md` or `installed_plugins.json` key); print one chat-only block listing every missing fulfiller + install commands, or one ✅ line if all satisfied. User-custom lines silently skipped; removed canonical lines silently skipped (respects user opt-out). Hard rule "never auto-install" carries over verbatim. Subsumes the deferred `[bootstrap-recommend-projects-meta]` task (closed by absorption — generic step handles `using-projects-meta` along with everything else). MCP-server-backed skills only check the `using-X` policy skill; `setup-X` self-fires on first use via Prerequisites pointer, bootstrap doesn't duplicate.

# Caveman Compress
## Purpose
Compress natural language files (CLAUDE.md, todos, preferences) into caveman-speak to reduce input tokens. Compressed version overwrites original. Human-readable backup saved as `<filename>.original.md`.
## Trigger
`/caveman:compress <filepath>` or when user asks to compress a memory file.
## Process
1. This SKILL.md lives alongside `scripts/` in the same directory. Find that directory.
2. Run:
cd <directory_containing_this_SKILL.md> && python3 -m scripts <absolute_filepath>
3. The CLI will:
- detect file type (no tokens)
- call Claude to compress
- validate output (no tokens)
- if errors: cherry-pick fix with Claude (targeted fixes only, no recompression)
- retry up to 2 times
- if still failing after 2 retries: report error to user, leave original file untouched
4. Return result to user
## Compression Rules
### Remove
- Articles: a, an, the
- Filler: just, really, basically, actually, simply, essentially, generally
- Pleasantries: "sure", "certainly", "of course", "happy to", "I'd recommend"
- Hedging: "it might be worth", "you could consider", "it would be good to"
- Redundant phrasing: "in order to" → "to", "make sure to" → "ensure", "the reason is because" → "because"
- Connective fluff: "however", "furthermore", "additionally", "in addition"
### Preserve EXACTLY (never modify)
- Code blocks (fenced ``` and indented)
- Inline code (`backtick content`)
- URLs and links (full URLs, markdown links)
- File paths (`/src/components/...`, `./config.yaml`)
- Commands (`npm install`, `git commit`, `docker build`)
- Technical terms (library names, API names, protocols, algorithms)
- Proper nouns (project names, people, companies)
- Dates, version numbers, numeric values
- Environment variables (`$HOME`, `NODE_ENV`)
### Preserve Structure
- All markdown headings (keep exact heading text, compress body below)
- Bullet point hierarchy (keep nesting level)
- Numbered lists (keep numbering)
- Tables (compress cell text, keep structure)
- Frontmatter/YAML headers in markdown files
### Compress
- Use short synonyms: "big" not "extensive", "fix" not "implement a solution for", "use" not "utilize"
- Fragments OK: "Run tests before commit" not "You should always run tests before committing"
- Drop "you should", "make sure to", "remember to" — just state the action
- Merge redundant bullets that say the same thing differently
- Keep one example where multiple examples show the same pattern
CRITICAL RULE:
Anything inside ``` ... ``` must be copied EXACTLY.
Do not:
- remove comments
- remove spacing
- reorder lines
- shorten commands
- simplify anything
Inline code (`...`) must be preserved EXACTLY.
Do not modify anything inside backticks.
If file contains code blocks:
- Treat code blocks as read-only regions
- Only compress text outside them
- Do not merge sections around code
## Pattern
Original:
> You should always make sure to run the test suite before pushing any changes to the main branch. This is important because it helps catch bugs early and prevents broken builds from being deployed to production.
Compressed:
> Run tests before push to main. Catch bugs early, prevent broken prod deploys.
Original:
> The application uses a microservices architecture with the following components. The API gateway handles all incoming requests and routes them to the appropriate service. The authentication service is responsible for managing user sessions and JWT tokens.
Compressed:
> Microservices architecture. API gateway route all requests to services. Auth service manage user sessions + JWT tokens.
## Boundaries
- ONLY compress natural language files (.md, .txt, extensionless)
- NEVER modify: .py, .js, .ts, .json, .yaml, .yml, .toml, .env, .lock, .css, .html, .xml, .sql, .sh
- If file has mixed content (prose + code), compress ONLY the prose sections
- If unsure whether something is code or prose, leave it unchanged
- Original file is backed up as FILE.original.md before overwriting
- Never compress FILE.original.md (skip it)

- Do not touch any section not mentioned in the errors
