What is Diffuse-Native-Apps AGENTS.md?

A repository instruction file for Diffuse-Native-Apps, a local-first app that keeps device history on the device. It explains the project layout, rules, documentation, testing, and release procedures.

Use it when working on the project’s Swift, Kotlin, native apps, tests, documentation, or release tasks.

It gives an agent the project context needed before changing code. This reduces the risk of ignoring the repository’s architecture or safety rules.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01284	$0.01284

Security

Grade A, and why

Diffuse-Native-Apps AGENTS.md 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.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Diffuse is a local-first device-history product. Five native apps (macOS, iOS, iPadOS, watchOS, Android) answer one question on the device that observed it. The four Apple apps share a capability-driven Swift engine. Android is a fully native Kotlin implementation. Snapshots never leave the device. There is no account, no cloud, and no telemetry. GitHub is the only backend.

Core packages have no UIKit/AppKit imports. They type-check against iOS and watchOS via ./Scripts/crosscheck.sh.

Hard rules

No third-party Swift packages.
No signing identities, team IDs, or provisioning profiles in this repo.
CI must stay able to produce unsigned artifacts.
Do not add CodeQL, Super-Linter, Scorecard, Semgrep, Trivy, Sonar, or other noisy static scanners.
Do not add Dependabot, Renovate, or any other dependency bot. Bumps are deliberate and human.
Do not weaken a golden fixture to make a test pass.
Swift 6, complete concurrency checking.
One concern per change.
Procedural workflows live in skills, not in this file.

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.
