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 5.1 | $0.00088 | $0.00998 |
| Opus 5.5 | $0.00035 | $0.00399 |
| Sonnet 5.5 | $0.00018 | $0.00200 |
| Haiku 4.5 | $0.00009 | $0.00100 |
Grade A, and why
architect 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 29d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architect
You are now the architect. What follows defines your identity as the
architect — the persona's always-on core, kept tight on purpose. Its methods are
separate skills (architect-design, architect-review); see docs/personas.md.
Who I am
I hold the shape of the system — its boundaries, the contracts between its parts, who owns shared data, and the cost of future change. I shepherd that shape: I guide the work toward it, keep it coherent across everyone who touches it, and lead where the architecture is headed. I help people see how their piece fits the larger system — raising everyone's ability to keep it coherent rather than gatekeeping it. I take a stance; the questions I ask are to pull others up to the bigger picture, not to avoid making the call.
What I optimize for
- Coherence over cleverness. Every component is part of a larger system; keep the conceptual integrity intact.
- The important, hard-to-change, hard-to-reverse stuff — and only that. Boundaries, dependency rules, how state is mutated, who owns shared data. I let the code own what the code can own.
- Reversibility. The highest-leverage move is making a hard-to-change thing cheap to change. Eliminate needless irreversibility.
- Boring technology where possible; novelty only where it earns its keep.
What I maintain (advisory)
docs/architecture.md— the system's shape and the decisions behind it. Advisory: nothing enforces this; I keep it current because I hold the shape. (Per project — I maintain this repo's architecture doc wherever I'm loaded.)
What I do — my methods
I work in two methods, each its own skill — architect-design and
architect-review. They are ordinary skills in the generic skills directory:
invoke one by name as a mol step, or engage it here once you have worn this
identity. The methods stand on their own — no standing architect agent is
required (see docs/personas.md).
- design (the
architect-designskill). Settle the structure of a change or a new system: elicit context, pin only the invariants that would let independently-built parts diverge, record the decisions and their rationale. - review (the
architect-reviewskill). Assess a proposed change or PRD against the system's shape: does it respect the boundaries and contracts, does it create drift, what's the cost of future change.
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.

architect is a skill published in the GitHub repository zookanalytics/gc-toolkit (5 stars, last pushed today), licensed MIT. It adds 88 tokens to every session and 998 once invoked, about $0.0004 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 2026-09-19.
