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.

What it costs to keep this loaded
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 | $0.00164 | $0.01296 |
| Opus 5.5 | $0.00066 | $0.00518 |
| Sonnet 5.5 | $0.00033 | $0.00259 |
| Haiku 4.5 | $0.00016 | $0.00130 |
Grade A, and why
contextpilot-savings 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 22d 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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ContextPilot Savings (Hermes)
This is a small, read-only skill: when a user wants to know how many tokens ContextPilot has saved, run the lightweight savings reporter and explain the result in plain language. That is the entire job — measure and report, nothing else.
Scope: show savings/status only. This skill never modifies ContextPilot code or config, never enables context routing/dropping/summarization, never schedules background jobs, and never edits the repository or opens code-change requests. If a user wants any of that, this is the wrong tool — stop and tell them so.
When to use this skill
- "How many tokens did ContextPilot save?"
- "Show me ContextPilot token savings" / "ContextPilot status".
- "Savings in the last 24 hours" / "savings all time".
- "Give me the raw savings data / JSON."
Privacy boundary (read this first)
The only thing this skill is allowed to read is the metadata-only telemetry
file (~/.hermes/contextpilot/telemetry.jsonl), and it reads it only
through scripts/contextpilot_savings.py. That file contains nothing but
numeric counters (timestamps, chars saved, tokens saved).
Do not, under any circumstances:
- read
~/.hermes/state.db, conversationmessages, or message content, - read system prompts, skill prompts, or reasoning fields,
- read raw tool-call payloads or tool outputs,
- read or print raw session ids.
If you are ever tempted to inspect any of the above to "explain" the savings, don't — the script's metadata summary is the complete, safe answer.
How to run it
Step 1 — Locate the script
Use whichever of these exists (check in this order):
scripts/contextpilot_savings.py— when you are in a ContextPilot repo or plugin checkout (current working directory).~/.hermes/plugins/ContextPilot/scripts/contextpilot_savings.py— when ContextPilot was installed as a Hermes plugin.
Pick the first one that exists and use that path as <script> below.
Step 2 — Run the reporter
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.

contextpilot-savings is a skill published in the GitHub repository EfficientContext/ContextPilot (141 stars, last pushed yesterday), licensed Apache-2.0. It adds 164 tokens to every session and 1,296 once invoked, about $0.0007 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 2026-08-30.
