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 | $0.00021 | $0.00666 |
| Opus 5.5 | $0.00008 | $0.00266 |
| Sonnet 5.5 | $0.00004 | $0.00133 |
| Haiku 4.5 | $0.00002 | $0.00067 |
Grade A, and why
coding-go 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Patterns
Error Handling
- Return
erroras the last return value - Use
fmt.Errorfwith%wfor error wrapping - Check errors immediately, never ignore with
_ - Define sentinel errors with
var ErrNotFound = errors.New("not found")
Concurrency
- Prefer channels for communication between goroutines
- Use
sync.Mutexfor protecting shared state - Always use
deferfor unlock/cleanup - Context propagation for cancellation
Imports
- Group: stdlib → external → internal
- One blank line between groups
- Use
goimportsfor automatic formatting

Anti-Patterns to Flag
- Ignoring errors with
_ - Goroutine leaks (no cancellation)
- Global mutable state
-
panic()in library code - Circular imports
- Naked returns in long functions
Quality Limits
protocol.config.yaml owns the file-length ceiling, and scripts/quality-report.ts
enforces it against every project-owned source file: max_file_lines (400 today).
There is no per-language override mechanism — no Go-specific ceiling is enforced
anywhere — so the rows below are style guidance, not gates.
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.

coding-go is a skill published in the GitHub repository savant0x/savant-code (11 stars, last pushed 3d ago), licensed Apache-2.0. It adds 21 tokens to every session and 666 once invoked, about $0.0001 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 2026-08-30.
