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 | $0.00400 | $0.00400 |
| Opus 5.5 | $0.00160 | $0.00160 |
| Sonnet 5.5 | $0.00080 | $0.00080 |
| Haiku 4.5 | $0.00040 | $0.00040 |
Grade A, and why
agent-regress AGENTS.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 2mo 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
AGENTS.md
Repository Context
This file serves as a system prompt and context guide for any AI coding agents that open this repository.
Project: agent-regress - A local MCP server that provides tools to run regression tests against AI coding agents using deterministic code checks.
Key Directives
- Semantic Evaluation is Deferred: The current architecture intentionally defers semantic evaluation (AI-judged tests) until post-MVP. If an eval specifies
pass_criteria.type: "semantic", theexecute_evaltool must return a hardcodedSKIPPED_SEMANTIC_MVPstatus. Do not attempt to implement semantic evaluation logic. - Deterministic Checks Only: All evaluations must rely solely on standard deterministic criteria (regex, JSON schema, exit code, exact match). Do not use AI to judge tests.
- Atomic File Operations: The
.eval_history/manifest.jsonfile uses a temporary file write and a retry-based rename loop to avoid race conditions with concurrent readers on Windows. Do not simplify this logic. - Process Tree Cleanup:
execute_evalusestaskkill /F /Ton Windows and-PIDprocess group termination on Unix to prevent orphaned subprocesses during timeouts.

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.

agent-regress AGENTS.md is an instructions file published in the GitHub repository Gaurav7974/agent-regress (0 stars, last pushed 3mo ago), licensed MIT. It adds 400 tokens to every session, about $0.0016 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 2026-08-31.
