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 | $0.06115 | $0.06115 |
| Opus 5.5 | $0.02446 | $0.02446 |
| Sonnet 5.5 | $0.01223 | $0.01223 |
| Haiku 4.5 | $0.00611 | $0.00611 |
Grade B, and why
ardur AGENTS.md scanned grade B with 1 finding 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Ardur Agent Instructions
The canonical entry point for coding agents working in this repository. These
instructions are mandatory. Human contributors should read
CONTRIBUTING.md and
docs/engineering-standards.md; this file
restates the parts an agent gets wrong most often and adds the parts that only
matter to agents.
0. First Action In Every New Session
Run the Conductor bootstrap before doing task-specific work:
./scripts/conductor-bootstrap.sh
Then read .context/ARDUR_CONTEXT.md. Its Generated Graph section is the
authority for graph availability:
- When the status is
available, read.context/ardur-graph.mdand use.context/ardur-graph.jsonas the machine-readable map of the repo. - When the status is
unavailable, continue with the live source and workflow files listed in the context. Missing graph artifacts are optional in this path and are not a bootstrap failure.
If the bootstrap fails, stop and inspect the failure before editing files. A failed bootstrap usually means the local toolchain, branch state, or generated context is not trustworthy yet.
Repo truth hierarchy. Use live repo state over stale prose, in this order:
git status, branch refs, and the actual files in this checkout..github/workflows/for the current CI surface.README.md,STATUS.md,docs/TESTING.md,docs/engineering-standards.md,docs/known-limitations.md, anddocs/decisions/.- Prior notes and generated
.context/files, after checking their timestamp.
If two sources conflict, cite the conflict and verify from the current tree.
This repo has changed quickly around Python and Go CI; the live workflow files
are the authority for what currently runs. That includes this file — if
AGENTS.md disagrees with a workflow, the workflow is right and this file is a
bug.
1. What Ardur Is, And What It Does Not Claim
Ardur governs AI-agent tool calls that pass through a configured adapter or proxy. It checks mission, resource, budget, and delegation constraints before that integration dispatches the call, then emits an issuer-signed, hash-linked receipt for the decision. The goal is to prove what your agents do, not just what they say.
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.

ardur AGENTS.md is an instructions file published in the GitHub repository ArdurAI/ardur (2 stars, last pushed 1mo ago), licensed MIT. It adds 6,115 tokens to every session, about $0.0245 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
