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 | $0.07438 | $0.07438 |
| Opus 5 | $0.03719 | $0.03719 |
| Sonnet 5 | $0.01488 | $0.01488 |
| Haiku 4.5 | $0.00744 | $0.00744 |
Grade A, and why
architecture-cowork-plugin CLAUDE.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 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.
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.
This is a copy
91% identical to architecture-cowork-plugin AGENTS.md — 81 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 577 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Archon Plugin — Global Rules
These rules apply to ALL commands in this plugin.
Plugin Development Rules — CRITICAL
Always edit the source repo, never the installed location
The plugin exists in two places:
- Source repo (edit here):
/Users/nexper/Code/architecture/backend/architecture-cowork-plugin/ - Installed location (read-only):
~/.archon/plugins/architecture-cowork/
NEVER edit files under ~/.archon/plugins/architecture-cowork/. Archon pulls the plugin from GitHub on refresh, which overwrites any changes made there. All edits MUST be made in the source repo, then committed and pushed to GitHub.
After pushing, Archon will pick up the changes on next refresh. If immediate effect is needed, copy the changed file to the installed location as well — but the source repo commit is the only durable change.
Keeping plugin, Archon, and SDL in sync
Before making any plugin change that touches diagram output paths, file naming, or IPC-visible behaviour:
- Check Archon's scanner —
mvp/archon/src/renderer/components/VisualiseStageView.tsxscansarchitecture-output/andarchitecture-output/diagrams/for.mmd/.png/.svg. Any new output folder the plugin writes to must be covered by Archon's scan, or diagrams won't appear. - Check SDL types —
mvp/archon/src/shared/types.tsandbackend/architecture/packages/sdl/define the data contracts. Plugin commands must not reference SDL fields that don't exist in the schema. - Test impact — if the change affects scaffold output (file names, folder structure, env var format), check whether the Archon Actions tab, env config dialog, and dev server components still work correctly with the new output.
- Never break the
.mmd→ Diagrams tab pipeline — the plugin writes.mmdfiles; Archon reads and renders them. Canonical filenames live indiagram-patterns/SKILL.md. Any rename there requires a matching update in Archon's display names if shown to the user.
Change workflow
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.
