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 | $0.00000 | $0.00298 |
| Opus 5 | $0.00000 | $0.00149 |
| Sonnet 5 | $0.00000 | $0.00060 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
fid-gates-unfenced-parser-contract 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 4d 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
FID Verification Gates: Unfenced Declarations Required
When bun run fid:verify <fid> --write fails with "malformed verification gates" / "no gates declared" on a FID whose - gate: lines visibly exist:
- The gate parser (
packages/agent-runtime/src/echo/fid-verification-gates.ts) strips ALL fenced code blocks BEFORE parsing — a ```markdown fence around your gates makes them invisible, and surrounding prose becomes malformed-declaration errors. - Fix: declare gates as bare unfenced lines directly under
## Verification Gates:
## Verification Gates
- gate: typecheck <workspace>
- gate: test <path-to-test-file>
No prose, no fences inside that section — any non-empty line that is not a - gate: bullet or receipt block is an error.
Evidence: recurred at FID-2026-0824-017 closure and again at master FID-2026-0824-013 closure (2026-08-25/26). Guard: after authoring any FID's gates section, grep it for triple-backticks between ## Verification Gates and the next ## heading — zero matches required.
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.

fid-gates-unfenced-parser-contract is a skill published in the GitHub repository savant0x/savant-code (11 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 298 tokens. 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 2026-09-04.
