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

go-build 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 today.

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

Go Build Command

Fix Go build, vet, and compilation errors: $ARGUMENTS

Your Task

  1. Run go build: go build ./...
  2. Run go vet: go vet ./...
  3. Fix errors one by one
  4. Verify fixes don't introduce new errors

Common Go Errors

Import Errors

imported and not used: "package"

Fix: Remove unused import or use _ prefix

Type Errors

cannot use x (type T) as type U

Fix: Add type conversion or fix type definition

Undefined Errors

undefined: identifier

Fix: Import package, define variable, or fix typo

Vet Errors

printf: call has arguments but no formatting directives

Fix: Add format directive or remove arguments

Fix Order

  1. Import errors - Fix or remove imports
  2. Type definitions - Ensure types exist
  3. Function signatures - Match parameters
  4. Vet warnings - Address static analysis

Build Commands

# Build all packages
go build ./...

# Build with race detector
go build -race ./...

# Build for specific OS/arch
GOOS=linux GOARCH=amd64 go build ./...

# Run go vet
go vet ./...

# Run staticcheck
staticcheck ./...

# Format code
gofmt -w .

# Tidy dependencies
go mod tidy

Verification

After fixes:

go build ./...    # Should succeed
go vet ./...      # Should have no warnings
go test ./...     # Tests should pass

IMPORTANT: Fix errors only. No refactoring, no improvements. Get the build green with minimal changes.

Changes

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.
