id-architect

id-architect is a skill for Claude Code from lukasrepublic/agentic-foundry. It costs 186 tokens per session (2,673 once invoked), scanned A, original, MIT.

A read-only design method for deciding where a locally running application should run in production. It designs the target infrastructure from requirements, expected load, cost, operations, and compliance needs, then audits that design.

In plain words
What is it for?
Use it to design a first deployment for an application that has no existing production setup, including selecting the platforms or infrastructure setups it should use.
Why use it?
It helps teams choose an infrastructure layout before writing infrastructure code. The result is advice and a design-audit note, not approval or deployment.

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

id-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 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 — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.

id-architect — read-only forward-design craft (infra-delivery step 2, ★ entry mode)

The infra-delivery step sequence (a documented procedure this skill family forms — no workflow engine or state-machine file ships) drives an infra change → merge. Step 2 has four entry modes, one per starting condition. id-architect is the entry mode for "the app runs locally, there is NO deployment yet — design where it should run." Unlike the adopt/codify onboarding modes — id-import (greenfield: codify live infra that already EXISTS but has no IaC), id-baseline (adopt an existing IaC repo + validate it is drift-free), id-discover (survey a routine change against an established baseline) — id-architect has no reality yet: it forward-designs the target topology from requirements, then runs the adversarial DESIGN-AUDIT loop to convergence BEFORE any IaC exists. It selects the platform(s)/stack-profile(s); the downstream spine is identical for all four entry modes.

ADVISORY — not a gate, no machine-adjudicated GREEN claim

This skill is ADVISORY craft FOR the trusted operator. It produces a design + a design-audit note; it does NOT gate, approve, or block any merge. Forward-design is a design + audit, not a change being delivered through a merge process — so id-architect makes NO machine-adjudicated GREEN claim (mirroring id-discover/id-baseline/id-verify/id-plan, which are advisory and not-self-certified). Because the design precedes the IaC there is no reality to diff against, so it does NOT depend on any coverage-delta attributability notion — that notion is structurally inapplicable here, not merely dodged. The both-modes floor is unchanged: front-authorization, the merge floor (the adopter's branch protection + CI checks — see docs/merge-floor.md) remains the only merge authority, security review, and typed contracts. Running id-architect makes the operator confident the target topology is sound — it is craft guidance FOR the trusted operator, not a defense against them.

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.

id-architect is a skill published in the GitHub repository lukasrepublic/agentic-foundry (1 stars, last pushed today), licensed MIT. It adds 186 tokens to every session and 2,673 once invoked, about $0.0009 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.
