truthgate

truthgate is a skill for Claude Code, Codex from ay7627514-dotcom/truthgate. It costs 23 tokens per session (334 once invoked), scanned A, original, MIT.

A verification workflow for Hermes tasks that checks factual claims, multi-step work, and external actions against evidence. Hermes is the task system this skill is designed to govern.

In plain words
What is it for?
Running a preflight check, following the approved plan, collecting tool and test evidence, and submitting the result for verification before reporting completion.
Why use it?
It reduces the risk of claiming that work is complete when the evidence does not support it. High-risk actions can also require a separate, task-specific approval token.

Token cost

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.

Security

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 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

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

  1. Call mcp_truthgate_truthgate_preflight before using external tools.
  2. Stop if status is blocked or needs_clarification.
  3. Preserve the returned task_id, task_digest, spec, and plan.
  4. Execute only the approved plan through Hermes' existing tools and approval controls.
  5. 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.
  6. Submit the final candidate and evidence through mcp_truthgate_truthgate_verify.
  7. 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 blocked as 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.
Files

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.

Changes

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.
