# CLAUDE.md — gaia-skill-heaven
Guidance for Claude Code (claude.ai/code) working in this repository.
## What this is
`gaia-skill-heaven` is the **product monorepo** for the Skill Heaven system and
doubles as the **Claude Code plugin marketplace** (root
`.claude-plugin/marketplace.json`; lists the Claude Code door `claude-zero`).
Per-harness doors for other harnesses (`pi-zero`, …) ship through their own
harness's channel, not this manifest. Two layers:
- **`packages/core`** — the shared profile-compiler engine and the
**`skill-zero` launcher/research driver** bin (`--print` recipes, `--record`
benchmark arms for the Hell/Heaven benchmark). Zero runtime dependencies;
TypeScript ESM.
- **`packages/claude-zero`**, **`packages/pi-zero`** — the per-harness
**doors** (the user-facing installables). `claude-zero` is the flagship
- (WS4); `pi-zero` is the vanguard (WS5). Every door defaults to the `off`
+ (WS4); `pi-zero` is the vanguard (WS5). Every door defaults to the `zero`
ladder rung; `native` is explicit. Per N9 the marketing weight is on
the doors; the engine is the research instrument they are built on.
- **Core product model — one mechanic, one line, four surfaces (N13).** The
- user-facing mechanic is **`/summon`** — one skill into context, one session,
- nothing installed — present in every implementation, at every rung, on every
- door. There is **one ladder — one line** — `off · low · med · high · xhigh ·
- max · ultra`, and the four surfaces are contiguous **bands** on it, read from
- the current rung. **`off` is Skill Zero** (the product floor — ships `/summon`
- by default, none of the choosing automated). **`low · med` is `/skill-heaven`
- (converge)**; **`high · xhigh · max` is `/skill-hell` (explore)** — two
- directions of the same summon over **one shared MCP**, where the rung sets
- **how many skills the agent may auto-summon per capability gap**. **`ultra` is
- Skill Ultra**, the **crown of the one line**: the controller that picks
- direction and depth per gap, rendered as the seventh selectable rung (it has
- no sub-ladder because it *is* the top of the one line). A session sits at
- exactly one rung — there is no separate Heaven and Hell position held at once.
- Per-rung counts and per-band defaults are **PROVISIONAL** until the benchmark
- lands (working mapping: `off 0 · low 1 · med 2 · high 3 · xhigh 4 · max 5`;
- Heaven's representative rung `low`, Hell's `high`). Up the line
- quality and cost rise together — **Skill Hell routes summons through gaia mcp
- as a mixture-of-agents for skills** (D5), so more summoned skills mean more
- experts in context, better until it isn't. The benchmark shapes the **entropy
- curve** (quality and cost vs skill entropy), not a token-savings headline
- (B6); **Heaven/Hell stamps are not built** — routing falls back to relevance
+ **Core product model — skill entropy, one line, four surfaces (N13).** The
+ ladder measures **skill entropy** — how much skill variety and volume enters a
+ session (full statement: `docs/LADDER-FLOW.md`). Rungs are entropy readings,
+ not settings: `zero · low · med · high · xhigh · max · ultra`, one line, and
+ the four surfaces are contiguous **bands** read from the current rung. The one
+ mechanic behind all of it is **`/summon`** — one skill into context, one
+ session, nothing installed — present at every rung, on every door. **`zero` is
+ Skill Zero**: zero skills, zero skill entropy, the product floor that ships
+ `/summon` by default with none of the choosing automated. **`low · med`
+ converges as `/skill-heaven`**; **`high · xhigh · max` explores as
+ `/skill-hell`** — the lower- and higher-entropy directions of the same summon,
+ over **one shared MCP**. **`ultra`** sits at the top of the same line and
+ picks the entropy for you, gap by gap. A session sits at exactly one rung —
+ never a separate Heaven and Hell position at once. **No rung carries a count
+ and no summon is capped** — how far a rung reaches on a given gap is the
+ agent's call, worked out in use while the benchmark is built; Heaven's
+ representative rung (`low`) and Hell's (`high`) are **PROVISIONAL**. The
+ benchmark's job is the **entropy curve**: quality and cost as skill entropy
+ rises, expected to rise then turn since Skill Hell routes summons through gaia
+ mcp as a **mixture-of-agents for skills** (D5) — not a token-savings headline
+ (N13). **Heaven/Hell stamps are not built**; routing falls back to relevance
ranking, and no surface may present stamp-gated routing as running. Public

## Layout
```
packages/core/ engine + skill-zero bin + vendored pure helpers (src/vendor) + parity fixture/tests
packages/claude-zero/ Claude Code door (off-default launcher, /skill-heaven chooser + /skill-hell, statusline) — WIP (WS4)
packages/pi-zero/ pi door — WIP/prototype (WS5)
```
## Commands
```bash
npm install
npm test # vitest across all packages (incl. the cross-repo parity fixture)
npm run typecheck # tsc --noEmit over packages/*
npm run launcher -- --posture floor --print # drive the core skill-zero bin
```
Node **≥ 22** (npm workspaces + the wider tooling assume it). **No runtime
dependencies — keep it that way.**
- ## Rule 0 — every harness invocation runs in a visible pane
-
- **Never invoke `claude`, `pi`, `codex`, `hermes`, or `grok` through your Bash tool.**
- Run them in a `herdr` pane so the full argv — especially `--model` — appears on screen.
-
- herdr is this project's benchmarking environment. A probe the operator could not see is not
- evidence, and the operator must be able to confirm which model actually ran. This applies to
- dispatched workers and nested subagents exactly as it applies to an orchestrator.
-
- ```bash
- PROBE_PANE=$(herdr pane split --current --direction down --ratio 0.4 --cwd "$PWD" \
- | python3 -c "import sys,json; print(json.load(sys.stdin)['result']['pane']['pane_id'])")
+ ## Rule 0 — LIFTED (owner ruling, 2026-08-19)
- herdr pane run "$PROBE_PANE" pi --model openai-codex/gpt-5.6-luna:low --print --no-session "probe"
- herdr pane read "$PROBE_PANE"
- ```
+ **Harness invocations may run on the Bash tool.** `claude`, `pi`, `codex`, `hermes` and
+ `grok` no longer have to be driven through a `herdr` pane; inline shells are fine, including
+ for the verification pass and code review.
- Record the pane id next to any result you rely on, so the run stays auditable.
+ Rule 0 previously required every harness invocation to run in a visible pane so the operator
+ could confirm which model actually ran. It was lifted once PR 7 landed and the plugin became
+ self-contained — the summon MCP now ships bundled inside `plugins/skill-heaven/`, so exercising
+ the product no longer means probing an external binary whose identity is in question.
- Ordinary shell work — `git`, `npm`, `node`, `curl`, file inspection — stays on the Bash tool.
- The rule is specifically about **harness invocations**, where model identity is at stake.
+ **What the rule was protecting is still real, and is now a deliberate choice rather than a
+ standing restriction.** If you run **benchmark arms**, where *which model produced a result* is
+ the evidence, that run has to be auditable on its own terms — a result the operator could not
+ see is not evidence. Reach for a visible pane then, and record what you did next to the number.
+ Ordinary work — verification, probes, code review, exercising the plugin — does not need it.

**`gaia-research/skill-cost` is the canonical basis for every cost measure.** Never
self-reported token counts — it reads persisted harness session logs and prices against
LiteLLM's catalog. See `packages/core/skills/cost-measurement/SKILL.md`.
## Adding a door for a new harness
**Read `packages/core/skills/harness-door-pattern/SKILL.md` first.** Five doors have been built
and the work is the same shape every time — most of the cost is the probe, not the code.
The short version: every harness hides its skills in one of about four places (allowlist flag
that reads like a suppression flag · native evict/readmit · config-home env var · already seeded
onto disk). Identify the class and you have most of the answer. The skill carries the per-harness
evidence, the probe methodology (self-report confabulates — use hard signals), the door package
shape, and nine traps that have each already cost time.
## Fan-out — parallelise mechanical probes, keep judgement central
Probe campaigns are the slow part of building a door, and most of a campaign is **mundane**:
run this argv, count the skills, repeat it twice, report the number. That work parallelises.
Deciding *what* to probe and *what the result means* does not.
**If you are a `pi` worker, you may fan out to `worker-luna` subagents for mechanical probe
work.** There is no cap on how many you use across a task.
```
subagent tool, parallel mode:
{ tasks: [ { agent: "worker-luna", task: "..." }, { agent: "worker-luna", task: "..." } ] }
```
`worker-luna` is GPT-5.6 Luna Medium in an isolated context. The extension caps a single call at
8 tasks with 4 running concurrently — batch larger sweeps.
**What to fan out:** running one probe cell, repeating a cell to check reproducibility, counting
entries in a snapshot file, enumerating flags from `--help`, checking whether a path exists,
grepping a source tree for a symbol.
**What NOT to fan out — this stays with you:**
- deciding which cells the probe campaign needs
- interpreting a result, especially a negative one
- judging whether a finding licenses `execSupport: "exec"`
- writing `PROBE.md`, the compile route, or any door code
- anything where being wrong is expensive and being fast is not valuable
Give each fan-out task the **exact argv** and the **exact thing to report back**. A subagent
asked to "investigate skill suppression" will return prose; one asked to "run this command twice
and report the integer after `Total:` from each run" returns data you can use.
- **Visibility still holds.** A fan-out runs inside your pane, so the operator sees it — that is
- what keeps Rule 0 intact through a nesting level. Do not move work off-pane to parallelise it.
+ **Report what you fanned out.** With Rule 0 lifted a fan-out is no longer visible on screen by
+ construction, so the audit trail is what you write down: say how many workers ran, what each was
+ asked, and what came back. A result nobody can trace to a task is not evidence.
- Orchestrator-level concurrency is unchanged: **two herdr pane workers at a time.** Fan-out
- happens *inside* one of those two, it does not add a third.
+ Concurrency: **two pane workers at a time** if you are using panes. Fan-out happens *inside* one
+ of those, it does not add a third.
## Non-negotiables (decision authority: `gaia-research/founder/RATIFICATION.md`)
- **M0 discipline** — nothing load-bearing ships ahead of an empirical probe on
a **pinned** harness version. A negative result is a first-class finding
(D8): record it, don't paper over it. The T9/T9b Claude routes hinge on an
**undocumented, version-pinned** env knob
(`CLAUDE_CODE_DISABLE_BUNDLED_SKILLS`) — **re-verify on every Claude Code
upgrade.**
- **One mechanic, one line, four surfaces (founder ruling N13, `docs/LADDER-FLOW.md`).**
`/summon` — one skill into context, one session, nothing installed — is
present on every door at every rung. There is one ladder — one line —
- `off · low · med · high · xhigh · max · ultra`, and the four surfaces are
- contiguous bands read from the rung: `off` = Skill Zero (ships `/summon` by
+ `zero · low · med · high · xhigh · max · ultra`, and the four surfaces are
+ contiguous bands read from the rung: `zero` = Skill Zero (ships `/summon` by
default as the product floor), `low · med` = `/skill-heaven` (converge),
`high · xhigh · max` = `/skill-hell` (explore) — two directions of the same
- summon over one shared MCP — and `ultra` = Skill Ultra, the crown rung: the
- controller that picks direction + depth per gap, rendered as the seventh
- selectable rung with no sub-ladder of its own. A session sits at exactly one
- rung. PROVISIONAL until the benchmark lands (working mapping `off 0 · low 1
- · med 2 · high 3 · xhigh 4 · max 5`; Heaven's rung `low`, Hell's `high`).
+ summon over one shared MCP — and `ultra` sits at the top of the same line
+ and picks the entropy for you, gap by gap. A session sits at exactly one
+ rung. No rung carries a count and no summon is capped; what each rung
+ reaches for is worked out in use until the benchmark lands (Heaven's
+ representative rung `low`, Hell's `high`).
Nothing on the line refuses — Hell is not gated, locked, or sealed at any
rung, and neither is Ultra; N13 ratified all four surfaces, so what is
outstanding is implementation, not permission.
Heaven/Hell stamps are not built; routing falls back to relevance ranking.
- **P3 — never mutate shared state.** The launcher composes flags and execs; it
never stashes, restores, or edits the user's `~/.claude`, settings, or
skills. The only writes live inside a disposable `mkdtemp` session dir.
- **D6 — thin cross-repo contract.** This repo **never imports `gaia-research`
code.** It vendors the small pure pieces in `packages/core/src/vendor/` (the
`chars4` tokenizer, listing-line format, frontmatter reader, `sha256(SKILL.md)`
ref, and the `hh-ledger/v1` type + validator). Parity is enforced two ways:
`packages/core/test/parity.test.ts` (fixture generated from the real
`gaia-research` `census.ts`) and the hard gate that every emitted record
passes `gaia-research`'s `scripts/hell-heaven-bench/ledger.ts validate`. If
you change a vendored helper, regenerate the fixture and keep both sides
byte-identical.
- **Two-number doses** — never price a skill as one number: standing (listing
line, paid every session) and invocation (full body, paid on invoke) are
always reported separately; `tokens.system` stays `null` until M2a ratifies.
## Git & PR rules
- **Never commit to `main` directly.** Branch as `feat/<workstream>-<slug>`
(e.g. `feat/ws2-monorepo-restructure`), open a PR, let CI + review gate it.
- **Preserve history on moves** — use `git mv`, never delete-and-readd.
- **One logical change per commit; commit frequently.** End commit messages
with the Co-Authored-By / session trailer the environment provides.
- **Draft PRs stay draft** until the owner marks them ready. Ratification
deltas ride the implementing PR (D9) — never split a decision from its code.
- **Never commit** `node_modules/`, build output, `.env*`, coverage, or session
temp dirs (`.gitignore` covers these).
- **Stay in your lane** — don't touch the Milim tree or unrelated
`gaia-research` surfaces from this repo.
### Merge verb (per-repo, and it is not the same one everywhere)
- **This repo squashes.** `gh pr merge <n> --squash --delete-branch`. A merge
commit is **blocked by a branch protection ruleset on `main`** —
`gh pr merge --merge` fails with `GraphQL: Merge commits are not allowed on
this repository`.
- **`gaia-skill-tree` and `gaia-research` are the inverse** — merge commits,
not squash. `gaia-skill-tree` has squash disabled outright; `gaia-research`
follows the merge-commit convention its release auto-sync classifies. Agents
routinely work across all three in one session, so **check the verb per repo,
never per project.**
- **Check before merging:**
`gh api repos/<owner>/<repo> --jq '{squash:.allow_squash_merge,merge:.allow_merge_commit,rebase:.allow_rebase_merge}'`.
Treat that as a floor, not the answer: **a ruleset on `main` can be stricter
than repo settings report.** This repo is exactly that case — the API says
`merge:true`, the ruleset rejects merge commits anyway.
