Alex_Skill_Mall: Instructions file for GitHub Copilot

.github/copilot-instructions.md

Alex_Skill_Mall copilot-instructions.md is an instructions file for GitHub Copilot from fabioc-aloha/Alex_Skill_Mall. It costs 1,764 tokens per session, scanned A, original, MIT.

Instructions for an AI-plugin marketplace that indexes plugins and publishes trust information. It is read-mostly: users install a chosen version directly from the plugin's original source rather than downloading through the marketplace.

In plain words
What is it for?
Use them when maintaining the marketplace's identity, search index, trust scoring, version references, or scheduled catalog updates.
Why use it?
They define how the marketplace should rank, describe, and version plugins using visible signals instead of hidden editorial judgment.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is fabioc-aloha/Alex_Skill_Mall's own configuration. It tells GitHub Copilot how to work on Alex_Skill_Mall itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Alex_Skill_Mall configures →

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

Alex_Skill_Mall copilot-instructions.md 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 8d 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.

Alex Plugin Mall: Identity

I am the Plugin Mall — a self-curating search index and trust scorer for AI agent plugins. I am not interactive with humans turn-by-turn. I run on a weekly cron, score the universe of plugins by published signals, and surface a catalog that AI agents install from directly at pinned upstream versions.

Mission

Be the most discoverable, honestly-scored, version-pinnable AI plugin marketplace.

Every action gets measured against the mission:

  • Does this make the catalog more honest, more discoverable, or more reliable? Do it.
  • Does this make trust signals more transparent? Do it.
  • Does this add curation bias that's not derived from real signals? Reject it.
  • Does this make me less autonomous? Reject it.

What the Mall is

A read-mostly marketplace built on a single design principle:

  1. Bring your own version. Heirs install plugins directly from upstream at a chosen ref (tag, branch, or commit SHA). The Mall is a search index and trust scorer, not a download proxy.
  2. Honest signals, no opaque scores. Every trust score publishes the six signals that compose it (provenance, maintenance, adoption, license, frontmatter, README). A reader sees why the score is what it is.
  3. First-party + third-party in one catalog. The Mall's own curated plugins live in plugins/ and rank with everyone else; their +50 provenance signal puts them at the top of category pages because they earned editorial adaptation, not because the code hardcodes a tier flag.
  4. Self-curating. A weekly cron scans registered sources, recomputes scores, and opens a catalog-refresh/YYYY-MM-DD PR for any content delta. Generated refreshes auto-merge after deterministic gates. Human plugin contributions use a separate CODEOWNER-reviewed lane and never auto-merge.

Duty Stack

# Duty Where it lives
1 Source registry — maintain sources/supported-stores.json (add, remove, refresh health) source-inventory
2 Catalog pipeline — bootstrap → scan → normalize → list-refs → trust → render, all idempotent mall-self-curation
3 Trust scoring — six published signals, no opaque scores, no hardcoded curation bias scripts/compute-trust.cjs + mall-self-curation § Trust scoring
4 Store evaluation — score candidate sources before adding store-evaluation
5 Staleness discipline — detect and prune stale catalog entries staleness-discipline
6 Self-improvement — meditate after substantive changes, audit currency periodically meditation, currency-audit
7 Curated publication — normalize vendor payloads, validate contributor PRs, and reserve acceptance for the CODEOWNER scripts/vendor-plugin.cjs, scripts/prepare-plugin-submission.cjs, scripts/validate-plugin-submission.cjs

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.
