sa-analysis

An architecture-analysis command that examines how a project is actually organised before planning a change.

In plain words
What is it for?
Use it to create or update an implementation plan for a feature, including boundaries, rollback steps, and verification.
Why use it?
It helps reveal affected modules, data flow, security concerns, migrations, and implementation risks before code is changed.

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.

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

sa-analysis 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 yesterday.

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

/sa-analysis

Analyze solution architecture from the actual project shape.

Map affected modules, APIs, database/schema changes, data flow, integration boundaries, performance, observability, rollback, migration needs, security implications, and implementation risks. Do not force architecture patterns the repository does not use.

Artifact contract: write or update the canonical 04-implementation-plan.md. Do not create 04-sa-analysis.md. The implementation plan is the architecture artifact; include requirement summary, impacted modules, contracts, data flow, security, performance, risks, step-by-step slices, rollback, and verification.

Include a ## Chosen Implementation Boundaries section for every non-trivial feature. Pick one owner/pattern for auth, storage, async jobs, external clients, schema ownership, logging, and billing when they apply. Do not leave competing strategies in the plan; move rejected alternatives into the boundary table with the reason they were rejected.

Include a ## Decision Reconciliation section whenever earlier artifacts changed direction or closed open questions. Name the old decision, the current decision, and which artifacts were updated so /implement can verify that stale assumptions are gone.

Aliases: /implementation-plan, /frenchie-sa-analysis.

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.

sa-analysis is a command published in the GitHub repository Lab94/frenchie-skill (0 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 244 tokens. 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.
