What is synkb CLAUDE.md?

Repository instructions for Claude Code contributors to the synkb project. They point to the project’s documentation for architecture, contribution rules, implementation plans, decisions, and security guidance.

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	$0.00983	$0.00983
Opus 5.5	$0.00393	$0.00393
Sonnet 5.5	$0.00197	$0.00197

Security

Grade A, and why

synkb 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.

CLAUDE.md

Guidance for Claude Code working in this repository.

This file is deliberately short. It carries only what an agent needs that is not already written for humans, and points at the human docs for everything else. When guidance would apply equally to a human contributor, it belongs in CONTRIBUTING.md — not here. Two copies of one convention drift, and the drift is invisible until someone acts on the stale one.

Question	File
What is this project, how do I run it?	README.md
Service conventions, shared-py, dev workflow, commit style	CONTRIBUTING.md
What to build next, and what "done" means	design/implementation-plan.md
Why is it like that?	design/decision-log.md
Architecture and the demo→production mapping	design/hld.md
UI labels and flows (source of truth)	docs/user-guide.md
What is a deliberate demo weakness vs a bug	SECURITY.md

Rules that are easy to get wrong

Work is scoped by work package. Locate the WP in design/implementation-plan.md and treat its acceptance criteria as the contract. Don't widen scope; if something belongs to a later WP, leave it.
Record non-obvious decisions in design/decision-log.md, newest at the top. The log is append-only: correct the record by adding an entry, never by editing history.
Documentation ships in the same commit as the change. A change without its doc update is incomplete — including docs/user-guide.md when a UI label or flow moves.
Never hand-edit apps/web/lib/api/schema.ts. It is generated from core-api's OpenAPI. Run make types and commit the result.
Unit tests are not sufficient for a mutation. vitest stubs fetch and skips core-api's proxy entirely, so a broken gateway path passes every unit test. Exercise new mutations against a live make demo stack before calling the work done.
DEMO_MODE branches are deliberate, not bugs to clean up. Production flips the flag and real auth takes over.
STUB: tools and "good enough for now" comments are intentional. They mark honest boundaries. Don't tidy them away — if a stub becomes real, delete the marker as part of that work.
Never commit machine-local paths, personal contact details, or secrets. The repo is public. The maintainer's only published contact route is LinkedIn peterturnerlondon; GitHub is Syntax753.

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.
