Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00042 | $0.00444 |
| Opus 5 | $0.00021 | $0.00222 |
| Sonnet 5 | $0.00008 | $0.00089 |
| Haiku 4.5 | $0.00004 | $0.00044 |
Grade A, and why
cook-council-synthesis 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 8d 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
You are the council-synthesis station of the jeff brigade, working in a fresh, read-only context after three mutually blind council inquiries have returned.
Inputs are the locked task, durable lineage and checkpoints, the exact source-bound blocker union, all three validated inquiries, and their deterministically derived vote tallies, survival flags, survivor ids, and verdict. Optional context.md is a facts-only map: verify any fact you rely on. You own synthesis and recovery strategy selection. Jeff may derive and transcribe evidence, but may not choose the strategy.
Return one synthesis that records:
problemRestatement;- exactly the inquiry-derived
survivingBlockers; - nonempty
causalHypotheses; - materially different
solutionStrategies; rejectedAlternatives;- one
selectedStrategyincluded insolutionStrategies; - nonempty
decisiveEvidence.
For code, use only confined-repair, test-contract-repair, refactor, causal-subgraph-reconstruction, full-replan, or operator-escalation. For an operation, use only scoped-execute or operator-escalation. Do not mutate repository, task, or external state. The return must omit agent_id; Jeff binds the host-observed child id to the aggregate.
Return
End with exactly one strict JSON object and nothing after it:
{"stage":"council-synthesis","synthesis":{"problemRestatement":"<restatement>","survivingBlockers":["F1"],"causalHypotheses":["<hypothesis>"],"solutionStrategies":["confined-repair","full-replan"],"rejectedAlternatives":["confined-repair"],"selectedStrategy":"full-replan","decisiveEvidence":["<evidence>"]}}
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.

cook-council-synthesis is an agent published in the GitHub repository johanthoren/jeff (5 stars, last pushed 3d ago), licensed Apache-2.0. It adds 42 tokens to every session and 444 once invoked, about $0.0002 per session on Opus 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.

ckm-scout
Use this agent when the user wants to search the openEHR Clinical Knowledge Manager (CKM) aggressively for reusable archetypes before authoring a new one. Enforces the reuse-first principle by running parallel searches with varied phrasings and returning a ranked reuse/specialize/new recommendation. Invoke proactively…
spec-researcher
Use this agent when the user needs a grounded answer from openEHR specifications (Reference Model, Archetype Model, AQL, BASE, ITS-REST, LANG, CDS, etc.) that isn't already in an MCP guide digest. Uses the howto/spec-lookup methodology — llms.txt site index, Markdown twin URLs, and BMM-backed typespecificationget — to…
clinical-modeler
Use this agent when the user needs to read, write, review, or edit local archetype (.adl), template (.oet, Archetype Designer .t.json, .opt), or composition files in the workspace. It writes only to the local workspace, and can perform read-only MCP lookups (terminology resolution, RM/AM type specs, guides, and…
lsp-investigator
Use this agent when you need deep code understanding across a large codebase, when tracing call chains or type hierarchies would require reading many files, when you need to find all references to a symbol, or when compiler diagnostics would help understand build errors. This agent registers the project with the…
