What is geogram CLAUDE.md?

Architecture and release instructions for Geogram, including shared code rules, storage access, deployment scripts, and project documentation. A station server is one of the project's server applications, and ProfileStorage is its safe file-storage interface.

Use them when changing desktop or server stations, accessing profile files, testing the client, consulting the API, or deploying updates.

They prevent duplicated implementations and unsafe access to profile data that may be encrypted.

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	$0.00658	$0.00658
Opus 5.5	$0.00263	$0.00263
Sonnet 5.5	$0.00132	$0.00132
Haiku 4.5	$0.00066	$0.00066

Security

Grade A, and why

geogram CLAUDE.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.

Key Decisions

DO NOT DUPLICATE CODE FUNCTIONALITY. Write libraries and make sure that apps are mostly using a single file without duplication of functionality in other parts of the code
When writing code for a station server, there are two implementations so write code that uses a library or common method that is called by the two implementations.
Always use ProfileStorage methods (not raw File/Directory) when accessing files inside the {callsign} profile folder — the folder may be inside an encrypted SQLite storage. Use AppService().profileStorage to get the storage instance.
Station code reuse: Never implement feature code on either CLI or Desktop station directly. Always write to shared libraries/mixins (lib/server/mixins/) and have both stations use the same code.

There is a script ./launch-desktop.sh to launch the client on this laptop and ./server-deploy.sh when needed to upload/update the server station.

Always use ./launch-desktop.sh for testing the code and client implementations, don't launch it separately without that script

Read ./docs/API.md for the debug API that automates testing. When a debug API endpoint does not exist, create one.

Never implement code features without testing them yourself first. Do the deployment, test that it works as intended.

Use ./docs/reusable.md to reuse code instead of duplicating functionalities, document new reusable components there

Always commit your changes with a proper change log

Write code that is based on DART and can run from the command line for libraries, so we can reuse it in other platforms

Another claude instance might be running on the same code base, be carefull. When you find code that is breaking your compilation to unrelated changes then ask the human

Release Process

Bump version in pubspec.yaml
Commit (pre-commit hook auto-updates lib/version.dart via tool/update_version.dart)
Tag with git tag v<version> and push with git push --tags
Create GitHub release — CI workflows will sed pubspec.yaml from the tag and regenerate version.dart before building

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.
