Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00087 | $0.00688 |
| Opus 5 | $0.00044 | $0.00344 |
| Sonnet 5 | $0.00017 | $0.00138 |
| Haiku 4.5 | $0.00009 | $0.00069 |
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 5d 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
aigdpackage (the orchestratoraigd/+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 onaigd/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), theproject 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 leastDraft(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 2mo ago), licensed MIT. It adds 87 tokens to every session and 688 once invoked, about $0.0004 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.
