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 | $0.00035 | $0.00247 |
| Opus 5 | $0.00017 | $0.00123 |
| Sonnet 5 | $0.00007 | $0.00049 |
| Haiku 4.5 | $0.00003 | $0.00025 |
Grade A, and why
triangulate 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 yesterday.
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
Triangulate
Match verification effort to the consequence of being wrong.
Tier 1: Ground
Before relying on a definite value or behavior, read its source-of-truth artifact in the current task: code, config, runtime output, screenshot, protocol, or official documentation. Most claims need nothing more.
Tier 2: Triangulate
Use multiple independent primary sources when:
- credible sources disagree;
- the claim gates an expensive, destructive, or hard-to-reverse action;
- a single artifact cannot establish the behavior;
- the user has challenged the claim; or
- the user explicitly asks for triangulation.
State the claim narrowly, identify which evidence supports it, and preserve meaningful disagreement. Use a subagent when isolation or parallel source reading improves the result, not as a mandatory step.
Create a durable audit artifact only when the user requests one or the active specification needs the evidence for future implementation. Do not turn ordinary repository facts into audit bureaucracy.
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.

triangulate is a skill published in the GitHub repository KodingDev/meridian (5 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 247 once invoked, about $0.0002 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.
