photonforge-yield-analysis

A manufacturing-variation and tolerance analysis workflow for photonic circuits using PhotonForge and Tidy3D. It models how process differences, such as waveguide width or silicon thickness, affect circuit results.

In plain words
What is it for?
Use it to build process-corner models and run Monte Carlo studies for photonic components under fabrication and temperature variations.
Why use it?
It helps estimate how often a design will work when real parts differ from their intended dimensions.

Made for: Claude Code, Codex.

Or install photonforge, the plugin that ships this one along with the rest of its 8 skills.

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

photonforge-yield-analysis 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 3d 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.

Files

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.

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.

photonforge-yield-analysis is a skill published in the GitHub repository flexcompute/plugin-marketplace (8 stars, last pushed 7d ago), with no licence file. It adds 177 tokens to every session and 2,653 once invoked, about $0.0009 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.
