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 | $0.00334 | $0.00334 |
| Opus 5.5 | $0.00134 | $0.00134 |
| Sonnet 5.5 | $0.00067 | $0.00067 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
gemini-time-injector 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.
What it actually says
Time-Injector Extension
This extension solves a known weakness of large language models: you cannot perceive real-world time on your own. While you are reasoning the wall clock keeps moving, tool calls take seconds or minutes, and the user may walk away and come back hours later — none of which is visible from text alone.
To compensate, the gemini-time-injector extension fires a hook on every
lifecycle event and feeds you <hook_context>…</hook_context> blocks
containing:
- Current ISO 8601 UTC time and local time (refreshed each turn).
- Session elapsed time since the session was opened.
- Idle gap since the previous hook event (e.g. how long the user took to reply, or how long a tool call took).
- Tool duration measured between the matching
BeforeToolandAfterToolhooks.
How to use this information
- Treat the most recent
[time-injector]block as the authoritative current time. Do not rely on your training cutoff or earlier injections. - If the idle gap or session elapsed is large, acknowledge it before acting (e.g. "It looks like a few hours have passed — let me re-check the state before continuing").
- When a tool takes notably longer than expected, mention it in your user-facing summary so the user can decide whether to investigate.
- Never invent timestamps. If asked "what time is it", quote the most recent injected time verbatim instead of guessing.
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.
