Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00013 | $0.00203 |
| Opus 5 | $0.00006 | $0.00102 |
| Sonnet 5 | $0.00003 | $0.00041 |
| Haiku 4.5 | $0.00001 | $0.00020 |
Grade A, and why
cost-analytics 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 5d 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
Cost Analytics
Description
Tracks token consumption and API costs across opencode, Hermes, and Gemini CLI. Computes daily/weekly/monthly projections and alerts when approaching free-tier limits.
When to Use
- After each agent API call (auto-triggered)
- Daily cost report generation
- When checking budget status
Process
- Read latest cost-history.json
- Compute today's total tokens by agent
- Compute weekly and monthly projections
- Compare against free-tier limits from settings.json
- Generate alert if approaching limits (80%, 90%, 95%)
- Update cost-analytics chart data
Output
Cost report with: per-agent breakdown, projections, alerts, recommendations
Agent Assignment
- Primary: opencode
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cost-analytics is a skill published in the GitHub repository modimihir07/agentic-os (165 stars, last pushed 24d ago), licensed MIT. It adds 13 tokens to every session and 203 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
