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 | $0.00023 | $0.00334 |
| Opus 5 | $0.00012 | $0.00167 |
| Sonnet 5 | $0.00005 | $0.00067 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
truthgate 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.
What it actually says
TruthGate for Hermes
Use TruthGate for factual claims, multi-step implementation, external actions, and any task where a false completion claim would cost time, money, or data. Do not add TruthGate overhead to casual conversation or creative drafting.
Required flow
- Call
mcp_truthgate_truthgate_preflightbefore using external tools. - Stop if status is
blockedorneeds_clarification. - Preserve the returned
task_id,task_digest,spec, andplan. - Execute only the approved plan through Hermes' existing tools and approval controls.
- Collect evidence IDs, tool results, exit codes, test output, and artifact hashes. Tool traces must come from a trusted host wrapper when signed traces are required.
- Submit the final candidate and evidence through
mcp_truthgate_truthgate_verify. - Report completion only when TruthGate returns
verified.
For a high-risk or irreversible action, a human issues a task-bound token with
the truthgate approve CLI. Call mcp_truthgate_truthgate_authorize
immediately before the action. The token is single-use.
Non-negotiable rules
- Never fabricate evidence or tool traces.
- Never reinterpret
blockedas permission to continue. - Never claim that a file, message, workflow, or deployment changed without direct tool evidence.
- A failed verification means repair the work or report the exact blocker.
What ships with it
1 file 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.

truthgate is a skill published in the GitHub repository ay7627514-dotcom/truthgate (0 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 334 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 2026-08-31.
