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 | $0.15703 | $0.15703 |
| Opus 5.5 | $0.06281 | $0.06281 |
| Sonnet 5.5 | $0.03141 | $0.03141 |
| Haiku 4.5 | $0.01570 | $0.01570 |
Grade A, and why
n8n-decanter AGENTS.md scanned grade A 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 11d 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.

n8n-decanter — agent & project guide (single source of truth)
This file is the single source of truth for coding agents working on the
n8n-decanter CLI itself (not on a synced workflow dir — that's the template's
AGENTS.md). It is tool-agnostic: Codex and opencode read it natively, and
Claude Code reads it through a one-line import in CLAUDE.md. Everything —
response style, project rules, changelog/docs/backlog duties, git workflow,
commands, architecture, and the shared recipes — lives here; keep the rules in
one place and let the per-agent files stay thin pointers.
PLAN.md is a separate, complementary source of truth: it is the CLI's
design document (data model, flows, past decisions). This file governs how
to work on the repo; PLAN.md governs what the CLI is. Keep both current and
don't let either drift from the code.
Response style
- Very compact — no long conclusions or wrap-up prose.
- Prefer bullet points over paragraphs.
- Highlight important things and decisions so they stand out.
Session labels: [decanter] #NN short name
Every session gets a label so concurrent sessions stay legible:
- Task maps to a numbered backlog Plan →
[decanter] #NN <name>(e.g.[decanter] #92 upstream auth). - Task has no plan →
[decanter] <name>(e.g.[decanter] plans reorg). There is no separate word for it — the missing#NNalready says there is no plan.
<name> is very short and precise — 2–3 words describing the actual work.
The subject in brackets is always decanter, never the plan number. The
sidebar these sessions are read in groups them by that word, and gives each
subject one icon and colour for good. A bare number gets no face — it names
nothing, and would spend a subject on a single task — so the labelling tool
refuses it outright. The plan number rides in the <name> instead, first
thing, where it still lines up with the branch and worktree at a glance.
Set the label yourself, as soon as the subject is clear. An agent no longer has to ask for one; on this machine's Claude Code setup that is:
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.

n8n-decanter AGENTS.md is an instructions file published in the GitHub repository buttjer/n8n-decanter (2 stars, last pushed today), licensed MIT. It adds 15,703 tokens to every session, about $0.0628 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
