Rewrite a target file (memory note, doc, scratch plan) in compressed caveman form to shrink its token footprint, preserving every technical fact, code block, and link. Shows a diff and confirms before overwriting. TRIGGER when: /caveman-compress <file> invoked, or asked to compress a doc/memory file.

Caveman Compress

Rewrite a file in compressed form. Read core rules first: .claude/skills/caveman/SKILL.md.

Scope (check first — refuse out of scope)

In-scope targets only:

files under .oh/memory/** (notes, daily logs)
untracked scratch files (not committed to git)
a file the user passes with explicit "compress this anyway" override

Everything else is out of scope — refuse with a one-line reason. In particular:

docs/**, README.md, CLAUDE.md/AGENTS.md — published / load-bearing prose; brevity is intentional there.
.oh/tasks/archive/** and other archives — not read by default; compressing is busywork that mutates the record for ~0 live-token gain.
.oh/context/**, .claude/skills/**, .claude/agents/** — auto-loaded / behavior-steering. Token budget there is /context-audit's job (it has a safe ablation gate); compression here can silently change behavior.

Procedure

Read the target file. Refuse politely if no path given, or if the path is out of scope (see above).
Rewrite prose at full level: drop articles/filler, fragments allowed.
Preserve verbatim: code blocks, commands, URLs/links, tables, frontmatter, file/symbol names, numbers, headings (structure intact).
Show the rewrite and an estimated token delta. Confirm before overwriting — this edits a tracked file; do not write without a yes.
On confirm, write the file. Report old → new approx token count.

Guardrails

Never compress: LICENSE, CHANGELOG.md, generated/lock files (*.lock, skills.lock), or anything under .github/. These have exact-format contracts.
Refuse files where compression would break a parser (JSON, YAML data, prd.json) — compression is for human-prose docs, not machine-read data.
Compressing a .oh/memory/ note is fine; preserve the ## Heading -- HH:MM UTC log structure (.oh/skills/retro/references/memory-protocol.md).

delegate

mifunedev/openharness

TRIGGER when: asked to delegate work, execute or parallelize a plan, "run this plan", "delegate this", or after /prd or plan creation. Decomposes work by dependency, launches worker sub-agents in parallel waves, validates completion, and reports results while preserving failure isolation and recursion limits.

wiki

mifunedev/openharness

Dispatcher for the harness wiki knowledge base — routes the first token of $ARGUMENTS to one of three subcommands: ingest, query, or lint. The corpus lives at .oh/skills/wiki/corpus/ (entity pages) and corpus/raw/ (immutable snapshots), owned by this skill and gitignored-by-default (curated entries are whitelisted into git with `git add -f`). Canonical schema: .oh/skills/wiki/references/schema.md. Full per-subcommand procedures live in references/{ingest,query,lint}.md. Always logs per the Memory Improvement Protocol. TRIGGER when: "add to wiki", "capture this page", "snapshot this source", "ingest <url|path>", or promoting a sub-agent draft -> ingest; "what does the wiki say about X", "find wiki entries for X", "look up X in the wiki" -> query; "lint the wiki", "regenerate the wiki index", "find stale/orphaned wiki entries" -> lint.

blog

mifunedev/openharness

Turn a source scenario into a publishable blog post. First supported playbook: Loom/demo-to-blog, where a raw notes file plus Loom screenshots become a polished site post after Advisor briefing, photo/text alignment audit, site convention audit, narrative/fact-check audit, source-faithful image handling (exact URLs or local files downloaded from them), optional social/channel-promotion artifact generation, and build verification. Manual-invoke only because it writes content and may spawn delegates. TRIGGER when: /blog <scenario> invoked; asked to create a blog post from a Loom/video/demo/transcript/screenshots; asked to turn .claude/specs/<name>/ demo.md into an openharness-web blog post.

mifunedev/openharness

Start, inspect, or stop T3 Code (`npx t3`) in the Open Harness sandbox. Use this for the browser-based T3 Code harness on port 3773, including tmux launch, pairing URL discovery, logs, status, and shutdown. T3 Code wraps an already-authenticated Claude Code, Codex, or OpenCode backend. TRIGGER when: user asks to run T3 Code, start `npx t3`, open the T3 browser UI, get the T3 pairing URL, check T3 Code status/logs, or stop T3 Code.

retro

mifunedev/openharness

Scientific session-closing retrospective: scan the current conversation, turn each signal into a falsifiable hypothesis, cite session evidence for AND against it, assign a verdict (supported / refuted / inconclusive) and a confidence level, then promote only supported, sufficiently-confident hypotheses into the harness memory tiers (.oh/memory/MEMORY.md, .oh/context/IDENTITY.md) behind a propose-then-confirm gate. Reflects on six learning/knowledge subsystems through the lens of this session — continual learning, context compression, reinforcement learning, wiki, docs, and memory scaffolding — and points at the deep-dive lint/audit skills rather than running them. Operationalizes the Memory Improvement Protocol (.oh/skills/retro/references/memory-protocol.md) as an explicit, evidence-driven, session-closing skill rather than a per-run afterthought. Always appends a log entry. TRIGGER when: /retro invoked, or session closing with decisions, surprises, or failures worth preserving.

autopilot

mifunedev/openharness

Self-improvement loop: each hourly run implements the oldest open issue labeled `autopilot` that has no open PR. When the queue is empty it runs first-principles `/harness-audit` research, files its own `autopilot` ticket from the top-ranked finding, and builds that. Decomposes via the pm agent, then runs `/ship-spec --issue`, which owns the build end-to-end (the two compacts bracketing implement, a worktree Advisor, `/delegate` workers running `.oh/scripts/ralph.sh`, the `/eval` gate, and the `/pr-audit` promotable undraft) through to a ready-for-review PR whose description states why this item was selected. Harness-infra only (skills/rules/docs/scripts/crons/wiki) — never sandbox application code. Runs in its own per-run tmux session. Caps: 6 open autopilot PRs created per UTC day AND 10 total open; never auto-merges. TRIGGER when: the hourly .oh/crons/autopilot.md fires, or invoked manually on demand (e.g. /autopilot --dry-run to preview the next selection).
