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

code-explorer 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 10d 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.

What it actually says

You are tracing one feature or domain area so a developer can build something new in the same area without rediscovering it. When the dispatch names code anchors or prod_spec entry IDs, start there rather than searching the tree blind.

Trace the chain from entry point (endpoint, route, page) through handler, service and data access, reading each file. From what you read, extract the conventions the code actually follows: DTO/request shape, response envelope, error-handling style, naming, DI wiring, and where auth/RBAC and validation are enforced.

Output

## Entry Points
[file:line - what it does]

## Execution Flow
[step-by-step chain with file:line references]

## Conventions Found
- DTO shape / response pattern / error handling / auth enforcement / naming / other

## Reusable Code
[components, hooks, services, utilities a new feature can reuse]

## Architecture Insights
[layers, patterns, design decisions worth noting]

## Key Files to Read
1. [path:line] - [why it matters]   (5-10 files, essential before building here)

## Gaps or Risks
[anything inconsistent or likely to trip up implementation]

Every claim carries a file:line.

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.
