aigd-system

aigd-system is a skill for Claude Code, Codex from ProdaZhang/aigd. It costs 87 tokens per session (688 once invoked), scanned A, original, MIT.

A discussion-led method for designing one system at a time. It produces the system's rules, a configuration table with test data, and an HTML prototype; a prototype is an early working model of an interface or system.

In plain words
What is it for?
Use it to define system rules, prepare sample configuration data, and build an initial HTML system prototype from a project charter and shared guidance.
Why use it?
It keeps early design work changeable before detailed interfaces, backend algorithms, or acceptance tests are fixed. This reduces rework while the design is still being discussed.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions Claude Code.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **Package contract**: install the whole `aigd` package (the orchestrator `aigd/`+`references/` and the 6 sub-skills (including aigd-ui-capture) placed at the sa.

Good fit Use it to define system rules, prepare sample configuration data, and build an initial HTML system prototype from a project charter and shared guidance.

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

aigd-system 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 31 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AIGD · system (single-system design) [minimal skeleton]

Package contract: install the whole aigd package (the orchestrator aigd/+references/ and the 6 sub-skills (including aigd-ui-capture) placed at the same level in this environment's skills directory, following the host agent, e.g. Claude Code's .claude/skills/), don't copy this skill alone — the body's ../aigd/references/ depends on aigd/ at the same level, copying it alone breaks the link.

Positioning

Phase 2. One pass per system. Produces only the three "cheap, will-change-during-iteration" things: rules / config (test data) / system prototype. Interface contract / acceptance cases / backend algorithms are not in this phase — deferred to aigd-handoff (after finalization), to avoid locking things down while the design is still changing and wasting churn.

Read / produce / write back

  • Read: this system's entry in the manifest (dependencies, referenced shared sources of truth), the project charter; ../aigd/references/methodology.md (it is authoritative).
  • Produce — the paths below are an engineering-layout example, the actual directories/filenames defer to the project charter "directory layout · naming conventions" (same source as the manifest cross-layer index):
    • docs/systems/<system>/rules.md (-01, tagged with R-numbers, prose with no bare numerals).
    • config/source/<table>.xlsx (with test data) + config spec.
    • docs/prototypes/<system>.html (single file, zero-dependency, clickable; illustrative data on the same scale as the config).
  • Write back: this system's cross-layer index in the manifest + Status = Draft; new enums / R-numbers registered in place into the global spec.

Methodology

Defers to ../aigd/references/methodology.md (this skeleton does not copy it). Be sure to remember: contract / acceptance / backend belong to handoff, not produced in this phase.

Admission / exit

  • Admission: this system's status in the manifest = Draft, and all its dependency systems are at least Draft (otherwise the base map is missing, go back to concept to fill it in first).
  • Exit: rules.md + config table (test data) + system prototype.html complete, manifest cross-layer index written → move to aigd-iterate.

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.

aigd-system is a skill published in the GitHub repository ProdaZhang/aigd (2 stars, last pushed 3mo ago), licensed MIT. It adds 87 tokens to every session and 688 once invoked, about $0.0003 per session on Opus 5.5. 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.
