What is wellness-air AGENTS.md?

Development instructions for a local MCP server that exposes indoor air-quality readings such as PM2.5, carbon dioxide, and AQI. AQI is a scale used to describe how polluted the air is.

They are for developing, testing, and extending the Wellness Air server and its air-reading tools.

They explain the server’s structure, tool naming, supported provider, and how to add another air-quality provider.

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	$0.00577	$0.00577
Opus 5.5	$0.00231	$0.00231

Security

Grade A, and why

wellness-air 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 2mo 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.

AGENTS.md — wellness-air

Notes for AI agents and human contributors working on this repo.

What this is

A local-first MCP server that exposes air-quality readings (PM2.5, CO₂, AQI, etc.) to any MCP-aware agent. v0.1 ships full AirGradient support; AirThings/PurpleAir/IQAir/Awair are scaffolded.

Source layout

src/index.ts — MCP entry. Registers tools, runs stdio or Streamable HTTP.
src/constants.ts — Versions, provider list, default ports/hosts.
src/services/airgradient-client.ts — Public + owned AirGradient API client. Implements US EPA AQI conversion from PM2.5.
src/services/{capabilities,privacy-audit,agent-manifest}.ts — Standard manifest surfaces.
src/tools/air-tools.ts — All 10 tools registered with the MCP server.
src/cli/commands.ts — doctor, setup, status, current CLI commands.

Tool naming

All tools follow the air_<verb_or_noun> pattern. Resources use the wellness-air:// scheme.

Adding a provider in v0.2

Create src/services/<provider>-client.ts modeled on airgradient-client.ts. Keep the AirReading shape consistent.
Wire the provider into air_current_reading and air_daily_summary switch in src/tools/air-tools.ts.
Add provider env vars to src/services/capabilities.ts configured-detection.
Update src/services/agent-manifest.ts optional_env.
Add provider notes to src/services/privacy-audit.ts.
Bump SERVER_VERSION in src/constants.ts AND version in both package.json and server.json.

Testing

npm test runs typecheck + build + smoke + metadata check.
npm run smoke exercises the MCP tool surface against a public AirGradient sensor.
npm run test:metadata ensures package.json / server.json versions stay in sync.

Privacy contract

AirGradient public reads = no auth, no PII, no token storage.
Owned-sensor reads = AIRGRADIENT_API_TOKEN from env, never returned in tool output.
All cached data lives under ~/.wellness-air (override with WELLNESS_AIR_LOCAL_DIR).
No third-party telemetry. The only outbound call goes to the configured provider.

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.
