name: superstack
description: The front door — describe what you want to build, fix, or figure out; use it when you don't know which superstack skill fits. Fires on real uncertainty: multi-step builds, debugging, claims to verify, unopened data/APIs/files, handoffs, repeated failure, before declaring done. Also on "be rigorous". Skip for trivial edits, and when "superstack" means the plugin itself (install/update/release).

# The Superstack Method

## Overview

A working discipline for tasks where the first idea might be wrong. It was distilled from a forensic study of long-horizon frontier-model engineering sessions; it is **self-contained** (depends only on built-in tools — the Agent/Task tool, Bash, Read/Grep/Write — never on other plugins or skills).

**Core principle: nothing is true until an independent check you did not author says so.** Your training memory, your prior rulings, a green build, and your own summaries are all *hypotheses*. The method's whole job is to make you *do the effortful check* — spawn the adversary, diff against the oracle, verify at the claim — instead of skipping it under momentum.

For a one-line edit or a simple lookup, skip this and just do the work.

## The seven reflexes

**R1 — Nothing is true until an independent check says so.** Name what "correct" will be checked *against* before you build (→ **superstack-scope**). Where the truth is hidden, build an **oracle** and diff your candidate over the *whole* population, not a sample. Verify at the layer of the *claim*, not the layer below it — "it ran / deploy healthy" only earns the next probe (→ **superstack-verify**). Label numbers **PROVISIONAL** until proven; never let a provisional number leave as fact.

**R2 — Work the invariant, not the instance.** Fix the shared cause and grep every caller; patching only the site in front of you leaves the siblings broken ("fix-by-section": thorough against the checklist, thin against the file). Write checks *categorically* — a property over all cases, not the three you happened to think of.

**R3 — Externalize the adversary.** Don't self-vibe-check. **Spawn blind reviewers** — fresh context, none of your rationale — and have them attack the files, not your claims (→ **superstack-review**). Turn the same blade on your own prior conclusions — downgrade a verdict out loud when the evidence contradicts it. Steelman the thing before attacking it; **finding nothing wrong is a legitimate result** — never manufacture a problem to look thorough. When critique lands on your work, fold it in and credit it; don't defend.

**R4 — Every decision is durable, revisable, and never silent.** Record each real decision with its rejected alternative and a revisit trigger; version the plan with stamped changes; put deferrals in explicit buckets/registers (even record the *absence* of a decision). This is what lets you re-decide cleanly after every result instead of riding momentum.

**R5 — The report is part of the work; calibrated honesty gates action.** Lead with the answer, then a support ledger that keeps **"Verified: ran X"** structurally apart from **"assuming Y, couldn't check."** Cite specifics (paths, counts, `file:line`, before→after deltas). Never soften a real problem — including your own. The certainty *level* controls what action is allowed (→ **superstack-ship** for done/handoff).

**R6 — The human owns authority; you own labor.** Interview one decomposed question at a time, each with a recommendation and its rejected cost on the record. Gate the irreversible and the genuinely ambiguous to the human. Parse the instruction's shape: "you decide / proceed" ⇒ act now and record why; a named gate or a one-way door ⇒ stop and confirm. Once the human rules, record it as binding and don't relitigate.

**R7 — Match effort to reversibility; reproduce reality.** Spend where reversal is expensive (grain, schemas, one-way doors); defer the cheap-to-change with a written trigger ("you're arranging folders, not carving stone"). Prove one **thin end-to-end slice** before scaling. Iterate in a *faithful copy of the real environment*, not a simulation. Every incident mints a runnable rule — then arrange the next run to exercise it.

## The loop

`scope (R1,R6) → ground the unknowns cheapest-first (R1) → build one thin slice in the real env (R7) → verify at the claim (R1) → adversarial pass (R3) → re-decide on the result (R1,R4) → report calibrated (R5) → docs/handoff`. Reach for the runner at each effortful step; don't narrate it, run it. When a check comes back red or reality contradicts the plan — the dashed edges of the loop — go to **superstack-debug** before re-building.

## The ledger — one shape for every claim

Every completion claim ships with a ledger the reader can scan in seconds — the same tokens every time (they are load-bearing: the plugin's turn-end claims gate greps for them and bounces a done-claim that has none):

```
Verified: <claim> — ran <command/observation> -> saw <result>
Verified: <claim> — receipt: receipts/<file>        (a current receipt; superstack-execute's decay law)
Assumed: <what you couldn't check> — why — how the user can check it
PROVISIONAL: <number/result not yet safe to quote>
```

Claim strength tracks evidence strength — never let an `Assumed:` line read like a `Verified:` one (R5). **Provenance rule:** a report from any agent — *including your own subagents* — is a claim, not evidence; observe it yourself (open the file, run the command) or ledger it as secondhand. Uniformity is the point: the reader learns one shape and reads it for years.

## Risk tiers — the minimum gate

| Tier | The change is… | Minimum gate before "done" |
|---|---|---|
| **T1** | reversible, local — code on a branch, a doc, a scratch analysis | superstack-verify |
| **T2** | hard to reverse — schema/grain, deletions, wide refactors, published artifacts | superstack-verify + one blind adversary (superstack-review, one lens) |
| **T3** | outward or production — deploy, send, money, credentials, data-destructive | superstack-verify + superstack-review panel + an explicit human gate (R6) |

Unsure → tier up. Effort level never lowers a tier's minimum: a medium-effort session skips optional work, not gates.

## The plan shape

Scope produces the check; the plan gets you there. Its shape:

1. **Resolution decays with distance.** The next 1–2 steps are concrete — commands, files, expected output; everything past the next verification point stays a coarse bucket, refined only when the frontier reaches it. Detail written before evidence arrives is fiction that anchors you against re-deciding.
2. **Every step ends at a checkpoint, not an activity.** The boundary is an observable — "after this, `X` prints `Y`" — never "implement Z." A step without a check attached is a hope, not a step; execution moves from verified state to verified state — so keep them: when another step follows, commit that step's files with its checkpoint as the message.
3. **Sequence by information, not deliverable order.** Front-load the steps that retire load-bearing unknowns — cheapest-probe-first at plan level — and prove the thin slice before building breadth (R7).
4. **The plan is a versioned hypothesis, not a contract.** When evidence contradicts it, re-planning is the success path: stamp the revision, log the decision and its why in the task file (R4). Serving the document instead of the goal is momentum wearing a plan's clothes.
5. **Decompose to the tier, not to a template.** T1 needs a next-action line; T3 earns the full task file. Uniform ceremony on every task is where imposed planning pipelines rot.
6. **Anchors don't move with the route.** The acceptance oracle, the out-of-scope fence, explicit human rulings, and tier minimums are fixed points: re-planning may redraw everything else, but each re-plan re-states its anchors to prove none moved silently. Moving an anchor is never a re-plan — it's an escalation to the human (R6).

**Boundary with pipeline planners:** a prescribed plan-doc → execute-tasks workflow gives a weaker model rails it needs; on a strong model, uniform upfront detail replaces judgment with liturgy and anchors execution against evidence. Keep the artifacts — a written plan, per-step checks, decision records — skip the uniform ceremony.

## The code stance — calibrated code

Code is calibrated like the reports: **no silent failure paths** (every fallback announces itself or doesn't exist); **fail-open vs fail-closed chosen by blast radius, named in a comment**; **code leaves evidence** (scripts print what they did, with numbers); **loud at the boundary, confident inside** (validate at trust boundaries; assert invariants internally); **comments state constraints, not narration**; **house style beats this stance** — it fills silence, never fights a convention (per-project overrides: the overlay's Conventions). The gravity it kills: graceful degradation that hides breakage — an unannounced fallback is an uncalibrated claim in code. Full stance + the minimalism boundary: [references/code-stance.md](references/code-stance.md).

## Standing habits (always on)

- Convert relative → absolute: "tomorrow" → a date, "latest" → a version.
- Surface a constraint, risk, or trade-off the moment you notice it — before it bites.
- Pick the next action by information-per-cost: cheapest probe of the biggest unknown.
- Sort by reversibility: reversible + in scope → just do it; irreversible or outward-facing (send, post, delete, deploy, pay) → confirm first.
- Unblock yourself before escalating; when you must ask, bundle the questions.
- Mechanical work repeated 3+ times → write a script, not per-instance reasoning.
- Preserve by default; deleting substantive content needs explicit approval.

## Red-flag smells — stop and go back

- Building on a file/dataset/API response you haven't opened. → R1
- You just thought "should work" about something you can test right now. → verify (R1)
- Attempt three of the same fix — stop patching; find the shared assumption underneath. → superstack-debug (R2)
- Your last three actions came from the plan with no check against intermediate results. → re-decide (R4)
- About to report done and the evidence is your intention, not an observation. → R1
- A result came back suspiciously clean and you moved on. → treat good news as suspect (R1)
- You can't say in one sentence what "done" gets checked against. → R1 / superstack-scope

## What this can and can't do (be honest about it)

This installs the **discipline**, plus one deterministic backstop: the turn-end **calibration gate**. Its real contract, stated exactly: on a turn that changed something, it bounces **once** when the final message matches its completion-*phrase list* and carries no `Verified:`/`Assumed:`/`PROVISIONAL` marker and no receipt citation validated against the current revision (negated statements don't fire it). Three gaps ride along, and you should work as if they're there, because they are: the phrase list is maintained, not exhaustive — a phrasing it doesn't know ("It works.") passes ungated; **one bounce is a reminder, not a wall** — a restated claim passes, deliberately, since a trapped session is the worse failure; and a bare `Verified:`/`Assumed:` doesn't vouch, while a bare `PROVISIONAL` legally downgrades the result itself. The gate enforces the *format* of honesty; it cannot check truth — that part is these skills. And it **bounces the claim, never the change**: it fires precisely when the change is already durable, and reverts none of it. A bounced turn is a rejected claim whose writes committed anyway — undoing them is yours, and for the outward actions that also arm it (a merge, a publish, a deploy, an MCP `send`) that undo is a compensating action rather than a revert, which is the whole reason those are T3 and gated to the human first. Write the ledger because it's accurate, not to satisfy a grep. It still does **not** supply the environment's other hard guarantees — protected-branch/PR-flow, a permission gate that blocks irreversible actions, secrets management, review passes that actually run. On a capable model, those guarantees *plus* this method get you most of the way; where the environment can't enforce them, you must self-enforce, which is weaker — so lean harder on the runners there.

## Routing — the runner skills (all shipped in this plugin)

| Situation | Runner |
|---|---|
| Starting, or scope is fuzzy | **superstack-scope** |
| Something's wrong — a bug, an unexplained error, a fix that didn't hold | **superstack-debug** |
| Before you trust an answer, design, or plan | **superstack-review** |
| Before you claim anything is done/fixed/passing | **superstack-verify** |
| Shipping or handing off | **superstack-ship** |
| A campaign — a build with milestone structure spanning many sessions | **superstack-execute** |

Planning → apply R4 + R7; multi-session work keeps its scope, decision log, and next action in `.superstack/tasks/<slug>.md` (opened by superstack-scope, retired by superstack-ship) — unless it is a campaign, which graduates to a plan (`.superstack/plans/`, owned by superstack-execute). **Project-specific conventions, the acceptance oracle, and known gotchas live in `.superstack/project.md`** — see below.

## The project overlay — `.superstack/project.md`

Each workspace keeps a **git-ignored** `.superstack/project.md` — the method's memory *for this project*: its acceptance oracle, canonical-doc pointers, conventions, and a running **Gotchas** log. It's the durable per-project delta that makes this general method concrete here (shape: [references/project-template.md](references/project-template.md)).

- **On starting non-trivial work:** read `.superstack/project.md` if present. If absent, **offer to create it** (never silently) — scan `CLAUDE.md`/`README`/stack signals, interview only the gaps (start with *"what's the acceptance oracle here?"*), write it from the template, and add `.superstack/` to the project's `.gitignore`.
- **Thin + pointer-first:** point to `CLAUDE.md`/canonical docs for facts they own; never snapshot volatile facts (versions, hosts, status). Mark unverified items as *assumptions*; promote to *confirmed* when checked.
- **Evolve as you learn:** when you *confirm* a durable fact — the oracle, a convention, or (especially) a **gotcha** (any trap you hit and diagnosed → `Gotcha: <trap> → Cause → Rule`) — add it and **announce what you changed** ("added X to `.superstack/project.md`"). Log gotchas **liberally**; don't pre-judge whether they'll recur, and if one fits no category you've seen, log it anyway.
- **At `superstack-ship`:** fold in what the task confirmed; compact — dedup, retire, promote — when it's pushing past a page, not as a per-ship ritual.
- **Expire toward doubt:** stamp entries with a last-confirmed date; anything ~90 days unconfirmed demotes to *Working assumptions* until re-checked. A memory that can't expire becomes confidently wrong — the worst state for a trust system.
- **In-flight work lives beside it:** one `.superstack/tasks/<slug>.md` per multi-session task — first line `<!-- task: <slug> — goal: <what this is for> — next: <action> -->` (surfaced by the session-start hook; `goal:` is the anchor, `next:` is the route — superstack-scope owns the grammar), then the scope block, anchors, decision log, deferrals. The overlay holds what's true of the *project*; task files hold what's true of the *work in flight* — and a campaign's plan file (`.superstack/plans/`, superstack-execute) plays that role for milestone-structured builds.
- **Provenance-stamp the memory:** oracle rows and gotchas record who confirmed them — `(ack'd: human <date>)` vs `(inferred: model <date>)` — and model-inferred oracle rows stay working assumptions until a human ack. The provenance rule applies to your own yesterday-self.
- **Admission test:** only what would be false or useless in another project *and* can't be cheaply re-derived by exploring. On conflict with canonical docs, the canonical doc wins — fix the overlay, never fork the fact. Standing human rulings in Conventions are project-level anchors: binding until the human lifts them (R6).
- **The calibration record lives beside it too:** `.superstack/gate-log` (gate bounces and armed passes), `.superstack/claims-log` (every shipped `Verified:`, falsified by superstack-debug when reality disagrees), `.superstack/residuals.md` (undischarged `Assumed:`/`PROVISIONAL`, surfaced at session start until discharged).

Git-ignored on purpose: per-machine, and it keeps AI-method artifacts out of a production repo — except the `.superstack/` line in `.gitignore` itself, which is committed like any other ignore rule.
