Hermes Agent is an AI assistant that learns from its use by creating and improving skills, retaining knowledge, searching past conversations, and adapting to its users. It is for people who want to run an agent through a terminal or messaging platforms while connecting it to different AI models and scheduled tasks.
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 5.1 | $0.00015 | $0.02498 |
| Opus 5 | $0.00008 | $0.01249 |
| Sonnet 5 | $0.00003 | $0.00500 |
| Haiku 4.5 | $0.00002 | $0.00250 |
Grade A, and why
pr-lens 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 today.
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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PR Lens Skill
PR Lens draws code as visually rich animated diagrams: diffs, architecture, data flows. You describe the diff or codebase as one JSON document (lanes, nodes, edges, ordered flows) and the CLI renders it as animated SVGs. There is no findings lens — PR Lens is a comprehension layer, not a review bot. There is no field for a bug, risk, or security note, and a document that invents one is rejected.
When to Use
- Asked to diagram, visualise, or explain a code change or a system.
- A pull request should carry an architecture or data-flow diagram.
- Keywords: PR Lens, diagram, architecture, data flow, visualise, pull request.
Prerequisites
- Node.js with
npx(the CLI runs vianpx @coldtea/pr-lens-cli@latest; no install step). gh(GitHub CLI) — optional, only for attaching diagrams to PRs.- Optional canvas publishing calls the third-party service prlens.dev (see step 4b).
How to Run
Run all commands with the terminal tool from the repository root.
-
Read the diff. When representing a code change:
git diff --find-renames <base>...<head>. The base is the merge base, not the tip of the base branch. If not expressing a diff, read the code to be visualised. -
Write the document to
.pr-lens/graph.json, followingreferences/graph-document.md.references/example.graph.jsonis a valid reference with three lanes, all four delta states, a hero edge, a seven-step flow, a nested drill-down tree and a six-step walkthrough. Read it before writing your first document — quicker than reading the reference. -
Validate, and fix.
npx @coldtea/pr-lens-cli@latest validate .pr-lens/graph.jsonFix every failure and run it again. Do not render an invalid document; do not "work around" a failure by deleting the element it names.
-
Render.
npx @coldtea/pr-lens-cli@latest render .pr-lens/graph.json --theme lightRender light by default unless the user requests another theme. The SVGs, the manifest and
drawn.graph.jsonland in.pr-lens/, which the CLI adds to the repository's .gitignore. Do not commit any of it — these files are rebuilt from the diff on demand. Each SVG is named after its view, theme and content hash;manifest.jsonlists them by lens and view.
What ships with it
4 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.

pr-lens is a skill published in the GitHub repository NousResearch/hermes-agent (245,160 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 2,498 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 2026-09-14.
