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 | $0.00074 | $0.02138 |
| Opus 5 | $0.00037 | $0.01069 |
| Sonnet 5 | $0.00015 | $0.00428 |
| Haiku 4.5 | $0.00007 | $0.00214 |
Grade A, and why
cvg-hybrid-plan-loop 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.
How it starts
The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hybrid Plan Loop
Run cvg-plan-loop with a fixed engine split: the planner runs on a
high-taste Claude design model, and every fresh plan reviewer runs in a Codex
CLI session. The design model's scarce quota is spent only where taste has
leverage — drafting and revising the plan; review rounds burn the cheap
engine. Cross-model review is also a feature: a different model family
reviewing the plan exposes blind spots same-model self-review tends to share.
Prerequisites
- Claude Code as the orchestrating platform: the
Agenttoolmodelparameter andSendMessagecontinuation are required. - A working
codexCLI (codex --versionsucceeds) with the convergo codex plugin installed, so codex sessions can load role skills by name. - Codex sessions run with whatever permissions the user's own codex configuration grants. Convergo passes no sandbox or permission flags; roles assume normal developer access — reading the repo and writing their /tmp/convergo findings and audit artifacts.
If either prerequisite fails, stop and report it. Do not silently fall back to a single-engine loop; the user chose this skill for the split.
Engine Bindings
Defaults; the user's invocation may override either tier.
| Tier | Default | Runs |
|---|---|---|
| Design tier | Claude fable via the Agent tool model parameter |
planner, plan revisions |
| Execution tier | codex exec -m gpt-5.6-sol at model_reasoning_effort=high — the current frontier codex pin, updated with plugin releases |
fresh plan reviewers |
Before the first spawn, echo the resolved bindings in one line — planner
model, reviewer engine and model, round cap — so a binding mistake surfaces
before any specialist runs. If codex rejects the pinned execution-tier
model (a retired id), fall back to the model the user's codex config
resolves to — respawn the specialist wrapper with the model pin dropped,
initial -m and resume -c overrides both — echo what actually ran (the
model: line of the run header,
never an assumption), and flag it to the user if it sits below a frontier
model at high reasoning effort: cross-model review only pays if the
reviewing engine is near-peer.
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.

cvg-hybrid-plan-loop is a skill published in the GitHub repository gomilesf/convergo (7 stars, last pushed 1mo ago), licensed MIT. It adds 74 tokens to every session and 2,138 once invoked, about $0.0004 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.
