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 | $0.03925 | $0.03925 |
| Opus 5.5 | $0.01570 | $0.01570 |
| Sonnet 5.5 | $0.00785 | $0.00785 |
| Haiku 4.5 | $0.00392 | $0.00392 |
Grade A, and why
ChainWeaver 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 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.

ChainWeaver — Agent Instructions
Single source of truth for all coding agents working on this repository. This file carries the stable global contract; path-scoped
AGENTS.mdfiles add durable local rules (see §11), and the detailed module inventory lives in docs/agent-context/module-map.md. For tool-specific wrappers, see the documentation map at the end of this file.
1. Project identity
ChainWeaver is a deterministic orchestration layer for MCP-based agents. It compiles multi-tool flows into executable sequences that run without any LLM involvement between steps.
- Python 3.10+;
from __future__ import annotationsin every module. - Small runtime dependency set:
pydantic,typer,tenacity,packaging, anddeepdiff. - Core philosophy: compiled, not interpreted — the executor is a graph runner, not a reasoning engine.
2. Domain vocabulary
Use these terms consistently in code, docs, comments, and PR descriptions.
| Canonical term | Never use | Meaning |
|---|---|---|
| flow | chain, pipeline | A named, ordered sequence of tool invocations (Flow) |
| tool | function, action | A named callable with Pydantic input/output schemas (Tool) |
3. Repository layout
Stable top-level shape only. The full per-module inventory — every module's responsibility, exports, and issue history — is the module map (a mechanically freshness-checked reference, not policy).

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.

ChainWeaver AGENTS.md is an instructions file published in the GitHub repository dgenio/ChainWeaver (6 stars, last pushed 10d ago), licensed Apache-2.0. It adds 3,925 tokens to every session, about $0.0157 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.
