Version status

The current source targets 2.1.0. It is not identified here as a tagged GitHub release. Pin an exact commit when you need an immutable installation. See CHANGELOG.md for the unreleased change set.

Install

Use the skills CLI for supported agents:

npx skills add Leonxlnx/unlazy

Add -g for a user-level install or --all for every detected agent.

Manual locations:

Claude Code:  ~/.claude/skills/unlazy
Codex CLI:    ~/.codex/skills/unlazy

Clone the repository into the relevant directory. Invoke it as /unlazy where slash skills are supported, $unlazy in Codex, or by a natural-language trigger from the skill description.

The core is SKILL.md. The checker and optional hook require Node 16 or newer and use no third-party runtime packages.

Quick start

Ask for substantial work with an explicit trigger:

/unlazy tree 5 refactor the payment module and verify every migration path

For a solo task, copy templates/gates-leaf.md to GATES.md, replace every placeholder, and inspect it without executing commands:

node <path-to-skill>/scripts/gate-check.mjs --status GATES.md

--status is the only mode that is always non-executing. On a new oracle with no exact approval record, a normal run prints its resolved command, expectation, working directory, shell, and PATH without executing it:

node <path-to-skill>/scripts/gate-check.mjs GATES.md

Do not treat normal mode as a permanent dry run: once the exact oracle is approved, normal mode can execute it.

CHECK: lines are shell code. After reading every command and called script, approve and run the ledger:

node <path-to-skill>/scripts/gate-check.mjs --approve GATES.md

Re-run all runnable gates, including gates already marked complete:

node <path-to-skill>/scripts/gate-check.mjs --reverify GATES.md

Use --help for the complete current CLI.

The gate contract

# Gates: pricing behavior

- [ ] G1: pricing fixtures render the expected tiers
  CHECK: node scripts/verify-pricing.mjs
  EXPECT: pricing verification passed
  EVIDENCE: pending

- [ ] G2: checkout integration succeeds from its package
  CHECK: node scripts/verify-checkout.mjs
  EXPECT: checkout verification passed
  CWD: packages/checkout
  EVIDENCE: pending

A runnable gate passes only when its process exits 0 and EXPECT: matches combined output. Both the captured stdout/stderr payload and the canonical UTF-8 combined string used by EXPECT: and its fingerprint must fit the 1 MiB limit; the checker never truncates a larger matcher string into success. Canonical automatic evidence begins with a versioned full SHA-256 digest of the parsed CHECK:, EXPECT:, and raw CWD: definition, followed by the exit and successful-output fingerprint before capped environment details. A checked runnable gate with missing, ordinary prose, legacy, malformed, or definition-mismatched evidence is stale and unmet. Existing manual gates with ordinary human evidence remain compatible. This unkeyed binding detects structural drift, not ledger tampering: anyone who can edit a ledger can forge canonical-looking evidence. --status and Stop detect definition drift without resolving a shell or executing a check, but old evidence is not re-execution; parent verification uses --reverify.

The parser rejects zero-gate ledgers, duplicate ids, incomplete runnable gates, invalid expectations, and abandonment with a missing reason or unknown gate id. It ignores fenced examples, preserves CRLF or LF when updating, and inserts a missing evidence line when needed. A valid abandonment is terminal handoff rather than success: the checker exits 1 with HANDOFF REQUIRED, and Stop allows exit while reporting qualified ids.

The checker can prove only the command oracle you declare. It cannot infer that an English title and arbitrary shell code mean the same thing. Good gates therefore:

• read the artifact or service named by the outcome
• print a success-only marker after all assertions pass
• test an absence check against a known positive control
• measure supplied figures instead of copying them into EXPECT:
• review consequential manual outcomes with evidence proportional to risk

Use the advisory, non-executing scripts/gate-lint.mjs to catch mechanically weak ledger patterns; add --strict when warnings should fail. Full specification: references/gates.md.

Shell and PATH

The checker uses --shell first, then UNLAZY_SHELL, then Node's platform default shell. That default is /bin/sh on Unix and process.env.ComSpec on Windows with the platform fallback. Checks inherit the launch environment, including PATH.

This matters on Windows: a checker launched from Git Bash can see Unix-like tools that the same checker launched from PowerShell does not. --shell changes the interpreter; it does not install grep, tail, tr, or other external programs. Portable examples call repository-owned Node scripts.

Parent re-verification should use the same declared shell and required toolchain. A shell or PATH mismatch is a failed verification to resolve, not successful evidence.

Security boundary

Approval records live under ~/.unlazy/approved by default. UNLAZY_APPROVAL_DIR may select another owner-private real directory, but its canonical target must remain outside the checked repository. Symlinked stores and linked, replaced, or non-private records fail closed. Each record is specific to the absolute ledger and gate, exact CHECK: and EXPECT:, resolved CWD: and shell, timeout, output and regex limits, regex worker limits, platform, and full inherited PATH. Editing any bound input requires approval again.

Approval is consent, not a sandbox. Approval storage is a canonical, owner-private directory outside the repository; records are accepted only as single-link private regular files. The environment-independent definition digest is separate from the runtime approval identity, which also binds resolved ledger/runtime context. Approval does not hash called scripts, fixtures, dependencies, or other transitive inputs. --status and Stop validate the recorded definition binding but do not inspect those artifacts; reinspect changed dependencies and run --reverify. See SECURITY.md for the bounded digest pattern when user-designed dependency identity is needed. Checks run with ambient filesystem, environment, credential, and network access. Scopes and ownership leases coordinate cooperating processes but do not restrict what a process can read or write.

Orchestration and parallel work

For work that needs fresh contexts, create one scoped pipeline under .unlazy/<scope>/:

.unlazy/<scope>/PLAN.md
.unlazy/<scope>/GATES.md
.unlazy/<scope>/gates/leaf-*.md
.unlazy/<scope>/gates/node-*.md

The driver rereads the current request and maintains a revisioned contract inventory that maps each independently required outcome or acceptance-changing constraint to an owner and observation. It fixes interfaces, dependencies, conventions, and file ownership before dispatch. Leaves use declared WAITING, READY, IN-FLIGHT, VERIFIED, or ABANDONED states. Branches use OPEN, VERIFIED, or ABANDONED.

Ready leaves may run together only after each declares complete, disjoint, repository-relative OWNS: paths and claims them:

node <path-to-skill>/scripts/gate-check.mjs --scope api --leaf leaf-1.2.1 --claim

Lease matching is conservative and may reject a safe-looking pair. It is a coordination guard, not write isolation. Use separate worktrees for colliding worktree-local output, and configure separate cache locations when cache writes can conflict.

Dispatch is rolling: when a verified leaf unblocks another, start the newly ready leaf without waiting for unrelated work. Gate checks remain sequential by default. --jobs <N>, where N is an integer from 1 through 64, is an opt-in rolling limit for independent checks and keeps reporting in ledger order.

For every independent READY set, open a native launch wave, record each host agent handle, and seal before the first wait. If a partial launch cannot recover, use the audited abandon --reason transition; never invent a handle or delete state. Read references/method.md, references/orchestration.md, references/dispatch.md, and references/parallel.md before parallel fan-out.

gate-check.mjs --scope <id> reduces the scope's ledgers and dispatch waves together. It prints ALL MET only when every gate is met and every wave is complete; an abandoned wave remains a non-successful HANDOFF REQUIRED outcome.

Optional Claude Code Stop hook

The hook scans the current session's resolved ledger and dispatch state and returns Claude Code's documented top-level decision: "block" response while gates remain unmet or launch waves remain incomplete. It does not execute checks. Its own session-keyed progress guard releases after six consecutive blocks without semantic gate/dispatch progress; metadata-only edits do not reset it. Abandonment stays visible as an explicit bounded handoff in pure, mixed-blocking, and final-release messages, without echoing free-form reasons.

Install only with the user's consent:

node <path-to-skill>/scripts/install-hooks.mjs
node <path-to-skill>/scripts/install-hooks.mjs --scope api
node <path-to-skill>/scripts/install-hooks.mjs --uninstall

Default installation writes .claude/settings.local.json. Keep that file, .unlazy/, and .unlazy-hook-state.json in the project's ignore rules. --shared writes absolute Node and hook-script paths into project settings, so it is usually not portable and can expose local directory names. --global writes the current user's Claude settings.

The installer preserves unrelated hooks, refuses malformed settings shapes, and identifies moved unlazy entries without depending on the install directory name. It writes settings atomically and creates <settings-file>.unlazy.bak beside an existing settings file before replacing it.

What 2.1.0 changes

The unreleased 2.1.0 source integrates the useful parts of community PRs while repairing their edge cases:

• strict shared ledger parsing and explicit named-file targeting
• --reverify, explicit --approve, and fail-closed exit-plus-EXPECT success
• --shell and UNLAZY_SHELL, with pre-execution PATH disclosure and resolved shell, CWD, exit, match, and successful-output fingerprint evidence
• scoped pipelines, session routing, atomic ledger updates, and serialized lease coordination
• rolling orchestration and opt-in --jobs, sequential by default
• native dispatch launch waves with auditable partial-launch abandonment
• revisioned PLAN contract inventories and final request reconciliation
• advisory gate linting with opt-in strict failure
• non-successful gate abandonment that cannot promote parent completion
• definition-bound automatic evidence shared by checker/status/Stop, with fail-closed legacy migration and manual-gate compatibility
• strict Windows file identity through comparable descriptor stats, including pinned Node 22.14.0/libuv 1.49.2 CI coverage
• bounded Windows timeout process-tree cleanup with a live nested-descendant CI regression
• session-keyed Stop-hook state and atomic settings updates with a backup
• Node 16 support, zero runtime dependencies, a package test command, and CI
• accurate security, portability, research, and reproducibility documentation

Research basis

Research supports the failure modes that motivate explicit structure; it does not prove that unlazy produces a fixed improvement.

• Detailed multi-part prompts still see partial compliance and premature truncation in tested models (Quantifying Laziness).
• Reasoning can stop exploration too early or continue beyond useful compute, depending on task and model (Thoughts Are All Over the Place, When More Thinking Hurts, OptimalThinkingBench).
• SlopCodeBench reports that no tested agent fully solved a problem end to end and that the best agent passed 14.8% of checkpoints. Checkpoint success is not task completion (SlopCodeBench).
• s1's budget forcing lengthens reasoning by appending Wait multiple times when the model tries to stop; it is not a claim that one token always improves work (s1).
• METR's Time Horizon 1.1 reports a 196.5 day overall P50 doubling-time fit and 130.8 days for the post-2023 fit. The shorter figure must not be described as the all-years estimate (METR Time Horizon 1.1).
• Closed-book knowledge-intensive tasks can hallucinate more with additional test-time compute, and compute-only post-processing cannot add ground-truth information that was not present (Test-Time Scaling in Reasoning Models Is Not Effective for Knowledge-Intensive Tasks Yet, COLM 2026).

Earlier README versions also cited a six-run internal comparison. The raw artifacts needed to reproduce those exact ratios and counts are not in this repository. Treat the results as historical design input, not a benchmark guarantee. The limitations and a protocol for a defensible rerun are in research/validation-protocol.md.
