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 | $0.00049 | $0.04049 |
| Opus 5 | $0.00024 | $0.02024 |
| Sonnet 5 | $0.00010 | $0.00810 |
| Haiku 4.5 | $0.00005 | $0.00405 |
Grade B, and why
port-scan scanned grade B with 1 finding 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
| `Permission denied` | Root required for SYN | Run with sudo or use `-sT` | The source is not reproduced here
No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

port-scan is a skill published in the GitHub repository zebbern/termstack (5 stars, last pushed 4mo ago), with no licence file. It adds 49 tokens to every session and 4,049 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

auto-devflow
Use when starting an issue, bugfix, feature, or refactor that benefits from an adaptive development workflow. Select lite, normal, pro, max, or ultra from task complexity and risk, then use only the coordination, review, and verification phases that the task actually needs.
langfuse
Interact with Langfuse and access its documentation. Use when needing to (1) query or modify Langfuse data programmatically via the CLI — traces, prompts, datasets, scores, sessions, and any other API resource, (2) look up Langfuse documentation, concepts, integration guides, or SDK usage, or (3) understand how any…
self-build
Builds isolated npm capability packages that operate on real project code and connects them to Peri through MCP/MCPP and MetaHarness. Use when adding tools, resources, remote skills or agents, creating a Bun/Node.js stdio server, linking .mcp.json, or changing the active prompt and middleware set.
heavy-verify-loop
Runs a user-level verification and repair loop against the real Peri TUI using ./dev.sh, tmux, logs, E2E helpers, and Advisor/Coder/Reviewer subagents. Use when a feature must be exercised as a real user and repeatedly repaired until fresh end-to-end evidence shows no blocking problems.
