btseytlin/ultrapack

Plugin Claude Code

ultrapack — lean, opinionated Claude Code and Codex skill pack for spec-driven, git-centered development.

btseytlin/ultrapack

Instructions file

Claude Code instructions for btseytlin/ultrapack, covering ultrapack, repo layout, naming, design principles and versioning.

btseytlin/ultrapack

Agent

Trace feature implementations through the codebase and return a compact map — entry points, call chain, 3-5 essential files with file:line references. Dispatched from up:uexecute when a codebase question needs answering.

btseytlin/ultrapack

Agent

Implement one trivial phase of an approved plan — typos, one-line fixes, mechanical renames, doc/copy edits, lint/import re-orders. Same procedure as up:implementer but on Sonnet for cost. Dispatched per-phase from up:uexecute when the phase is unambiguously trivial.

btseytlin/ultrapack

Agent

Implement one phase of an approved plan — code, tests, commit. Default implementer for complex phases (multi-file, new logic, TDD, interface changes). Dispatched per-phase from up:uexecute.

btseytlin/ultrapack

Agent

General-purpose deep research. Decomposes a query, investigates systematically across the web, library docs, and the current codebase, returns a synthesized answer shaped by the question. Use when the main agent needs external knowledge beyond what Context7 or a quick web search gives.

btseytlin/ultrapack

Agent

Independent code review against a task's Plan, Invariants, and Assumptions. Stance — the future maintainer's audit: sit in the chair of the next person to touch this code and ask 'what will bite us later?' at the decision level. Single dispatch. Confidence-filtered (≥80), severity-tiered, with optional Scope flag.…

btseytlin/ultrapack

Agent

Draft a session-handoff summary so a fresh agent can continue with zero conversation context. Locates the current session's JSONL transcript by grepping for a distinctive phrase, reads it, and merges with repo state. Never writes to disk.

btseytlin/ultrapack

Command

Explain something like a colleague explaining to another engineer. Picks a realistic depth, explains it in one message, offers follow-up threads.

btseytlin/ultrapack

Command

Orchestrate the full ultrapack workflow — slug, task file, design, plan, execute, verify, review. Size-aware, resume-ready. Prefix args with handsoff for hands-off mode (fewer prompts, conservative defaults, decision log).

btseytlin/ultrapack

Command

Reflect on the current dialogue, extract what's worth keeping, and route each learning to its right home — CLAUDE.md, memory, or project docs.

btseytlin/ultrapack

Command

Circuit breaker — stop, diagnose why attempts are failing, propose a fundamentally new direction before trying again.

btseytlin/ultrapack

Command

Produce a summary so another session can continue with zero context beyond CLAUDE.md, the codebase, and the summary itself. Asks whether to append to the current task file or create a new summary task file.

btseytlin/ultrapack

Command

Manually test the latest change with one positive and one negative case. Goal is speed — shortest path to confidence.

btseytlin/ultrapack

Skill Claude CodeCodex

Run a bounded implement-attack-repair loop for a user-specified task. Use when work needs repeated independent criticism: perform the task, dispatch a fresh attacker, verify significant findings, repair them, and stop on a clean attack or the user's round limit.

btseytlin/ultrapack

Skill Claude CodeCodex

Explain a file, error, design, diff, or concept like a helpful engineering colleague: grounded in evidence, concise, and with useful follow-up threads. Use when the user asks for a clear explanation of the current work or codebase.

btseytlin/ultrapack

Skill Claude CodeCodex

Use when a task needs isolation from the current workspace. Picks a worktree directory via a fixed priority order, verifies it's gitignored, creates the worktree, auto-detects project setup, runs baseline tests.

btseytlin/ultrapack

Skill Claude CodeCodex

Contract for hands-off mode — the ultrapack workflow variant that minimizes user prompts after Design, takes the safest reversible path, and logs every auto-choice for one end-of-task review. Referenced by the workflow entry point and child skills (udesign, uplan, uexecute, uverify, ureview). Read when the task file's…

btseytlin/ultrapack

Skill Claude CodeCodex

Use to babysit a long-running process (training run, batch job, migration, deploy) on a remote pod or locally while the user is away. Defines a launch contract, gates on immediate crash, polls for stability, triages anomalies as recoverable (fix + resume) or not (tear down + notify). Auto-triggers when the user asks…

btseytlin/ultrapack

Skill Claude CodeCodex

Orchestrate the full Ultrapack workflow in Codex: create or resume a task file, design, plan, execute, verify, review, and validate the observable goal. Use when the user asks to build, fix, or deliver a non-trivial change with the complete workflow.

btseytlin/ultrapack

Skill Claude CodeCodex

Extract durable, non-obvious lessons from the current dialogue and route them to project guidance, memory, documentation, or the active task conclusion. Use when the user asks to reflect on a session or preserve learnings.

btseytlin/ultrapack

Skill Claude CodeCodex

Break a failed implementation loop by tracing attempts, identifying the real blocker, and proposing a materially different direction before further changes. Use when repeated fixes or investigations are not converging.

btseytlin/ultrapack

Skill Claude CodeCodex

Produce a compact, zero-context handoff for the current Codex work and, after user confirmation, save it to the active task conclusion or a new task summary file. Use when the user asks to preserve progress for a later session.
