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 | $0.00214 | $0.00214 |
| Opus 5.5 | $0.00086 | $0.00086 |
| Sonnet 5.5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
eai-gofer gofer-cost.instructions.md 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
Gofer Token And Cost Policy
Before running Gofer stages, spawning agents, or loading large files:
- Treat
.specify/memory/gofer-model-policy.yamlas advisory policy. Choose the lowest-cost model qualified by a fresh signed host receipt and independent benchmark evidence. Do not select a model from a static name or price. - Escalate only when a cheaper qualified pass is low-confidence, contradictory, security-sensitive, release-critical, or blocking quality.
- Keep raw search, build, and test output out of the main chat context. Write
stable findings to
.specify/specs/{feature}/context-bundle.mdand continue from summaries. - Prefer provider prompt/context caching for stable non-secret prefixes: Gofer scaffold, repository instructions, constitution, repo map, stage contracts, and validation rubric.
- After large research, planning, implementation, or validation bursts, checkpoint artifacts and compact/clear/resume context when the host supports it.
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.
