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 | $0.03596 | $0.03596 |
| Opus 5.5 | $0.01438 | $0.01438 |
| Sonnet 5.5 | $0.00719 | $0.00719 |
| Haiku 4.5 | $0.00360 | $0.00360 |
Grade A, and why
mattermost-mcp AGENTS.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 4d 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
86% identical to servicenow-api AGENTS.md — 160 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 — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mattermost MCP Agent Specs
Agent contract
Tool-neutral rules for any AI agent or human working in this repository. This block is maintained by the fleet standard; edit outside the markers.
- Owner boundary: this repository owns one external system's calls, mappings and MCP tools (spec prefix
CONN-MATTERMOST-MCP-); it depends on the connector SDK only. Feature routing across repositories: ecosystem boundaries. - Setup: run
scripts/bootstrap.sh. It is idempotent and non-interactive: it pins uv and Python, syncs the locked environment, installs the git hooks and prints the gate command. - Gates:
uvx pre-commit run --all-filesmust pass before you push. Do not bypass hooks to get green. - Commits: one logical change per commit with a
Spec: <ID>trailer (orSpec: none (<reason>)), plus aCo-Authored-By:trailer naming the assisting agent. Stage explicit paths only; nevergit add -Aorgit add .. Use your own configured Git identity, never a tool or bot name. - Org rules: organization AGENTS.md.
Canonical guidance for any AI coding agent or human; tool-specific entry files (for example
CLAUDE.md) only import this file. Edit this file.
This file acts as a machine-readable README for AI coding agents collaborating on this repository.

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.
