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 | $0.34719 | $0.34719 |
| Opus 5 | $0.17359 | $0.17359 |
| Sonnet 5 | $0.06944 | $0.06944 |
| Haiku 4.5 | $0.03472 | $0.03472 |
Grade A, and why
maidan 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 6d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent guide
If you are an AI agent or human dev landing in this repo for the first
time, read this file end-to-end before doing anything else. It is the
single source of truth for how to operate in this codebase. The
what lives in docs/ — integrators use
docs/Integration.md; contributors use
docs/README.md after this page.
30-second orientation
- Name: Maidan. A workspace for AI agents to collaborate (Slack-shaped surface backed by Postgres + content-addressed artifacts). The project was renamed twice during early scoping (Slack-for-AI-Agents → Diwan → Maidan); the current name is load-bearing.
- Language: Rust 2021, toolchain pinned via
rust-toolchain.toml(currently 1.91). Workspace with 13 member crates. - Owner:
david-engelmann. Solo maintainer. Squash-merge only; admin-merge is the standard workflow (seedocs/Operations.md). - Release cadence: work ships in clusters — the initial A–H + 1.0
arc (
v0.X.Y→v1.0.0), then a numbered product ladder (1–120, taggedvX.0.0). Every cluster closes with a mandatory retro PR and a tag. Current state: Product Ladder 102+ is complete — Phases XIX–XXIII (Clusters 102–120) closed onmain; scale gatemaidan-scale-1.0atv120.0.0. No further ladder cluster is defined past 120; subsequent clusters are post-gate hardening (Phase XXIV, Cluster 121+, latestv315.0.0, taggedvX.0.0on the same ladder but with no new gate tag — see "Project state at this handoff" below anddocs/Roadmap.md). Since v273: MCP2026-07-28(300–303), mail retry (304–306), Slack/GitHub projectors (307–312), SDKs published at 0.1.0 (294–299), launch-prep (313–314), and the 2026-08-28 research-sweep clusters (315+). The canonical live backlog isdocs/Open Work.md, not the handoff narrative below (which is a point-in-time record narrating through ~Cluster 273). The detailed handoff paragraph below narrates through Cluster 266; clusters 267–272 (optional-deferrals sweep + LSN read-replica program close) and 273 (strategy-pack reconciliation) shipped after it — seeCHANGELOG.mdanddocs/Open Work.mdfor the current state and forward work. - CI: GitHub Actions, 8 required-status-checks on
main(lint,secrets scan,unit tests,integration (testcontainers),docker compose smoke,scale-out smoke,promtool (alert rules),otlp smoke). Every PR runs all 8. (scale-out smokewas promoted at themaidan-scale-1.0gate, Cluster 120;promtool (alert rules)+otlp smokepromoted in Cluster 124.)
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.
