superforge-dev

superforge-dev is a skill for Claude Code, Codex from takaoumehara/superforge-skill. It costs 244 tokens per session (2,440 once invoked), scanned A, original, MIT.

A guide for splitting large, multi-part coding tasks among agents and choosing how much model capability each task needs.

In plain words
What is it for?
Use it when building features that touch multiple components, deciding between subagents or agent teams, and planning safe parallel implementation.
Why use it?
It reduces conflicting edits, duplicated work, and poorly defined parallel tasks by requiring a clear outcome, proof, and file list for each task.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

superforge-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Superforge Dev — Multi-Agent Building & Model Tiering Engine

Use this skill when implementing multi-component features, executing complex build plans, or dispatching subagents. It ensures optimal model tiering and agent topology selection.


0. Split the work before choosing anything else

Topology and model tier are decisions about how to run tasks. They cannot rescue a bad split, and a bad split is where unattended runs actually fail — agents that conflict, duplicate, or wait.

A task is well-formed only when it has one outcome, a proof line, a listed set of files it will touch, and no question left to ask. The file list is not bookkeeping; it is what makes the next rule decidable:

Two tasks may run in parallel only if the set of files they write does not intersect. Not "probably do not conflict" — listed, and disjoint.

Shared foundations — schema, shared types, design tokens, the route table, a dependency upgrade, any rename — run alone and first, then fan out. Most failed parallel runs are one of those done concurrently with its dependants.

The never-parallel table, how to find the dependencies a file list cannot show, how much context to hand each agent (both too little and too much fail, in different ways), what to do when a subtask fails — revert before retry — and when not to split at all → references/decomposition.md.

The schema is the shared foundation that runs first and alone, and it is also the one part of a product that gets harder to change as the product succeeds — code with no users can be rewritten in an afternoon, a table with real rows cannot. The decisions that are cheap now and expensive later (IDs, timestamps, money, deletion, the ownership chain every authorization check reads), the three causes of every data performance problem, and how to run a migration against data you cannot restore → references/data-design.md.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

superforge-dev is a skill published in the GitHub repository takaoumehara/superforge-skill (1 stars, last pushed 19d ago), licensed MIT. It adds 244 tokens to every session and 2,440 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
