slicc: Instructions file for GitHub Copilot

.github/copilot-instructions.md

slicc copilot-instructions.md is an instructions file for GitHub Copilot from ai-ecoverse/slicc. It costs 971 tokens per session, scanned A, original, Apache-2.0.

A set of Copilot code-review instructions for a project with web, browser-extension, Node, Swift, and iOS runtimes.

In plain words
What is it for?
Use it when reviewing changes that involve network failures, shared features, DOM updates, Chrome DevTools Protocol capture, native permissions, or Apple File Provider extensions.
Why use it?
It directs reviews toward missed error handling, inconsistent behaviour between runtimes, lost user-interface state, Chrome debugging edge cases, and macOS permission or signing issues.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is ai-ecoverse/slicc's own configuration. It tells GitHub Copilot how to work on slicc 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 slicc 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

slicc 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 yesterday.

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.

SLICC — Copilot Code Review Instructions

Review SLICC's five runtimes (webapp, extension, Node, Swift, iOS) against these blind spots. Flag only genuine risks. Catalog: docs/review-patterns.md.

1. Error-path coverage (often Critical)

External calls need bounded failure: timeouts, retry/backoff, surfaced errors. Flag unbounded fetch(), E2B calls, async work.

2. Cross-runtime parity (often Critical)

Shared behavior needs peer updates or explicit exclusion. Check Node ↔ Swift (endpoints, signing, DA origin allow-list / aem:// #2811), browser ↔ extension (mounts, VFS, secrets).

3. UI state preservation

DOM rebuilds (innerHTML, replaceChildren, reflow) must capture and restore live state.

4. CDP / Chrome edge cases

Foreground the page (Page.bringToFront() / wake renderer) before screenshots or capture. Validate CDP target + port before trusting them; handle disconnects.

5. Native / macOS permissions

Native protected-resource access needs entitlements/usage descriptions, TCC checks, graceful denial. A File Provider appex must embed+sign every @rpath framework it links (host Resources/ is invisible) and declare its transport's network entitlements. No keychain-access-groups on the macOS File Provider: that restricted entitlement needs an appex-specific Developer ID profile, else AMFI refuses launch (extensionKit error 2).

6. Model metadata / provider pipeline

When model IDs or provider metadata change, verify reasoning, input, cost, thinking levels through discovery, enrichment, account storage, API effort mapping.

7. Test coverage

New src/ files need mirrored tests; changed logic updated tests; bug fixes a regression test. Don't lower coverage floors.

8. Follower surface wiring parity (often Critical)

Leader broadcasts need follower handlers and UI actions. Check live, follower, and extension boot paths; preserve shared fallbacks; prefer capability checks to float names.

9. Origin / bridge routing contract (often Major)

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.
