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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

prose-guide 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 1mo 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
What it installs
The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 162 tokens a session between them. Each is measured on its own page, and each can be installed alone.
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.

prose-guide is a plugin published in the GitHub repository AndyElessar/skills (2 stars, last pushed 2d ago), with no licence file. Its token cost is not measured: this kind of file is read by the harness, not the model. 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.
Other plugins, from other repositories
implementation
Disciplined implementation stage: execute approved plans inline (/implementation:implement) or via orchestrated worker subagents (/implementation:implement-dispatch) with incremental validation, TDD-by-default cadence, green-checkpoint commits, scope-fence drift detection, and divergence detection that routes back.
context-guard
Per-session context-window observability. A mod writes each session's context-window figures to a snapshot file and shows the person a toast and a transcript line when the context zone (smart, acceptable or dumb, from bands in zones.json) worsens; with modelnotices on (off by default) it also tells Claude the zone at.
performance
Measurement-first optimization workflow for an arbitrary target, built around refusing to report what the data does not support. Five skills: target (identify and rank optimization candidates by evidence quality rather than suspicion, so an unmeasured target makes "instrument this first" the recommendation instead of…
instruction-placement
Routes agent instructions to the surface that loads them at the right time. audit finds conventions narrower than the always-loaded CLAUDE.md or AGENTS.md, or stranded in docs Claude never loads, and proposes a destination with a validated paths glob; safety content is never demoted. realign applies each move and…
desktop-notification
Alert you when Claude Code needs input: an audible terminal bell, an OSC 9 terminal notification, and an OS-native toast (macOS/Linux) on permission and idle prompts.
docs-hygiene
Documentation-hygiene toolkit: compress (trim markdown with a semantic-diff check), audit-noise (classify markdown noise), extract-ssot (deduplicate into a single source of truth), audit-encapsulation (citations into skill-private files), rename-references (stale references after renames), audit-derivability (does a…
