do-it-architecture

do-it-architecture is a skill for Claude Code, Codex from tdwhere123/do-it. It costs 28 tokens per session (300 once invoked), scanned A, original, MIT.

An architecture-governance guide for decisions about ownership, public interfaces, stored data, dependencies, migrations, recovery, safeguards, and structural removal.

In plain words
What is it for?
Use it when changing core system structure, deciding who owns data or behaviour, migrating between implementations, defining recovery paths, or removing dependencies.
Why use it?
It helps prevent changes from breaking contracts, crossing ownership boundaries, or leaving old and new systems inconsistent.

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

do-it-architecture 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 today.

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.

What it actually says

Architecture

Locate the load-bearing path from entry through mutation and accepted state to visible effect and recovery. Distinguish public, persisted, cross-boundary, and private surfaces; the narrowest actual compatibility promise matters.

Separate semantic authority (meaning and legal states), admission (permitted input or mutation), projection (derived views), and recovery (committed, retry, repair, or reconcile). One semantic authority does not require one physical writer. Place policy with the owner of end-to-end intent.

Ask whether a valid path bypasses a proposed guard and whether the rule would remain if its current layer were replaced. Derived caches and copies should not silently become competing authorities.

Explore applicable denial, duplication, races, replay, cancellation, timeout, and partial or uncertain commit. Identify the recovery owner and the invariant that survives failure. For a boundary change, account for consumers, compatibility, migration, rollback, and eventual retirement.

Challenge necessity before adding an abstraction, service, or governance layer. An independent strategist can test premises without inheriting the author's conclusion. Use architecture rationale or the stateful scan where their detail helps; a private reversible choice does not need a dossier.

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

do-it-architecture is a skill published in the GitHub repository tdwhere123/do-it (27 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 300 once invoked, about $0.0001 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 2026-08-30.
