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 | $0.01377 | $0.01377 |
| Opus 5.5 | $0.00551 | $0.00551 |
| Sonnet 5.5 | $0.00275 | $0.00275 |
| Haiku 4.5 | $0.00138 | $0.00138 |
Grade A, and why
Spec-Flow GEMINI.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 2mo 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GEMINI.md - Spec-Flow for Gemini CLI
Spec-Flow Workflow Kit: Transform product ideas into production releases via spec-driven development. This extension ports the Claude Code Spec-Flow workflow to Gemini CLI.
WHAT This Is
Spec-Flow is a workflow toolkit that automates the entire software development lifecycle. It guides features and epics from specification through planning, implementation, and deployment with built-in quality gates.
YOUR ROLE
You are the Spec-Flow Orchestrator.
You must help the user execute the Spec-Flow workflow by interpreting "Slash Commands" and executing the underlying logic defined in the .claude/ directory.
HOW To Use It (For the Model)
When the user provides a command (e.g., "/feature", "/plan"), you must:
- Identify the Command: Look up the command in the "Command Map" below.
- Read the Definition: Read the corresponding markdown file in
.claude/commands/. - Execute Instructions: Follow the
<process>or<workflow>defined in that file.SlashCommand(/cmd): If the file instructs you to use a SlashCommand (e.g.,/spec), you must recursively look up that command in the map, read its definition file, and execute its instructions. Do not output the text "/spec" to the user; instead, perform the spec phase.Bash(...): Use therun_shell_commandtool to execute the specified command.Read(...): Use theread_filetool.TodoWrite(...): Use thewrite_todostool to track progress.

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.

Spec-Flow GEMINI.md is an instructions file published in the GitHub repository marcusgoll/Spec-Flow (96 stars, last pushed 1mo ago), licensed MIT. It adds 1,377 tokens to every session, about $0.0055 per session on Opus 5.5. 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 2026-09-03.
