ECC is a toolkit that organizes and improves how coding agents work through skills, memory, security checks, research practices, and related extensions. It is for developers using agents such as Claude Code, Codex, OpenCode, and Cursor.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00006 | $0.00418 |
| Opus 5.5 | $0.00002 | $0.00167 |
| Sonnet 5.5 | $0.00001 | $0.00084 |
| Haiku 4.5 | $0.00001 | $0.00042 |
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 1mo 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
Go Build Command
Fix Go build, vet, and compilation errors: $ARGUMENTS
Your Task
- Run go build:
go build ./... - Run go vet:
go vet ./... - Fix errors one by one
- 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
- Import errors - Fix or remove imports
- Type definitions - Ensure types exist
- Function signatures - Match parameters
- 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.
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.

go-build is a command published in the GitHub repository affaan-m/ECC (284,906 stars, last pushed today), licensed MIT. It adds 6 tokens to every session and 418 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
