architectural-proposals

architectural-proposals is a skill for Claude Code, Codex from Azure-Samples/eShopLite. It costs 18 tokens per session (1,429 once invoked), scanned A, a copy of architectural-proposals, MIT.

A structure for writing architecture proposals before coding begins. An architecture proposal explains how a system should be built, what will change, what stays the same, and which risks or decisions matter.

In plain words
What is it for?
Use it for major architecture changes, new technical foundations, product direction changes, multi-stage work, or changes to external dependencies.
Why use it?
It creates agreement early, when changing a document is cheaper than rewriting code after assumptions have spread.

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

architectural-proposals 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 9d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

Proposals create alignment before code is written. Cheaper to change a doc than refactor code. Use this pattern when:

  • Architecture shifts invalidate existing assumptions
  • Product direction changes require new foundation
  • Multiple waves/milestones will be affected by a decision
  • External dependencies (Copilot CLI, SDK APIs) change

Patterns

Proposal Structure (docs/proposals/)

Required sections:

  1. Problem Statement — Why current state is broken (specific, measurable evidence)
  2. Proposed Architecture — Solution with technical specifics (not hand-waving)
  3. What Changes — Impact on existing work (waves, milestones, modules)
  4. What Stays the Same — Preserve existing functionality (no regression)
  5. Key Decisions Needed — Explicit choices with recommendations
  6. Risks and Mitigations — Likelihood + impact + mitigation strategy
  7. Scope — What's in v1, what's deferred (timeline clarity)

Optional sections:

  • Implementation Plan (high-level milestones)
  • Success Criteria (measurable outcomes)
  • Open Questions (unresolved items)
  • Appendix (prior art, alternatives considered)

Tone Ceiling Enforcement

Always:

  • Cite specific evidence (user reports, performance data, failure modes)
  • Justify recommendations with technical rationale
  • Acknowledge trade-offs (no perfect solutions)
  • Be specific about APIs, libraries, file paths

Never:

  • Hype ("revolutionary", "game-changing")
  • Hand-waving ("we'll figure it out later")
  • Unsubstantiated claims ("users will love this")
  • Vague timelines ("soon", "eventually")

Wave Restructuring Pattern

When a proposal invalidates existing wave structure:

  1. Acknowledge the shift: "This becomes Wave 0 (Foundation)"
  2. Cascade impacts: Adjust downstream waves (Wave 1, Wave 2, Wave 3)
  3. Preserve non-blocking work: Identify what can proceed in parallel
  4. Update dependencies: Document new blocking relationships

Example (Interactive Shell):

  • Wave 0 (NEW): Interactive Shell — blocks all other waves
  • Wave 1 (ADJUSTED): npm Distribution — shell bundled in cli.js
  • Wave 2 (DEFERRED): SquadUI — waits for shell foundation
  • Wave 3 (ADJUSTED): Public Docs — now documents shell as primary interface

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.
