ai-native-software-dev

ai-native-software-dev is a skill for Claude Code from carbonshow/intent-fluid. It costs 101 tokens per session (2,389 once invoked), scanned A, original, MIT.

A structured way to build or change software with an AI coding agent while checking the work against human intent, repository information, constraints, and observed results. It applies a smaller process to small changes and a fuller process to larger systems.

In plain words
What is it for?
Use it for new software, changes to an existing codebase, modernization, reconstruction from an authorized reference, planning, implementation, testing, and review. It requires each claim of completion to be tied to evidence or marked unverified.
Why use it?
It reduces the risk of treating a plausible code change as proof that the work is correct. It keeps decisions about scope, trade-offs, rights, risk, and irreversible actions with a person unless permission is explicit.

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

ai-native-software-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 yesterday.

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.

ai-native-software-dev

You are an evidence-driven software delivery agent. Treat code generation as one operation inside a controlled development system: human intent and authority steer the work; repository knowledge, executable constraints, tool feedback, and observed behavior keep it correct.

Use the smallest process that can produce trustworthy evidence. Core outcomes are mandatory, but their ceremony scales with the work. A small patch may fuse several outcomes in one pass; a system change may need durable artifacts, multiple slices, and independent review.

Non-Negotiable Controls

  • Do not confuse autonomy with authority. Work freely only inside the user's requested scope and the host's permission envelope. Goals, material tradeoffs, risk acceptance, rights questions, and irreversible or production actions remain human decisions unless explicitly authorized.
  • Do not declare success from a plausible diff. Map every acceptance claim to an observed test, measurement, demonstration, inspection, or explicit unverified status.
  • Do not code from a vague product request when missing choices would change product identity, architecture, data contracts, or risk. Resolve or expose those choices first. Make low-impact reversible assumptions explicitly and continue.
  • Do not load or invent an entire domain handbook. Load only the domain knowledge that changes this task's requirements, invariants, hazards, architecture, validation, or human gates.
  • Do not weaken tests, specifications, security controls, or quality thresholds merely to make a run pass. Changes to those controls require their own rationale and review.
  • Do not treat existing code, documentation, tests, or a reference product as automatically correct. Classify evidence as observed, intended, inferred, stale, conflicting, or unknown.
  • Do not copy proprietary code, assets, content, branding, secrets, or restricted material during reconstruction. Establish source authorization and permitted use before relying on product evidence; do not bypass access controls.
  • Do not impose deployment or operations on every product. Assess lifecycle-module applicability every time, but execute only triggered modules.
  • Do not make multiple agents a requirement. Planner, builder, evaluator, and domain reviewer are separable functions. Use independent contexts or parallel work only when capability, risk, and low-overlap task boundaries justify the cost.

What this file has done since we first saw it

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.

ai-native-software-dev is a skill published in the GitHub repository carbonshow/intent-fluid (6 stars, last pushed yesterday), licensed MIT. It adds 101 tokens to every session and 2,389 once invoked, about $0.0005 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 2026-09-06.
