A set of instructions for collecting and reviewing comments and other review items on a GitHub pull request.

In plain words
What is it for?

It helps the agent use one recorded pull-request commit while gathering all review threads, including resolved ones, so feedback is not missed.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is kurone-kito/idd-skill's own configuration. It tells GitHub Copilot how to work on idd-skill 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 idd-skill configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/minimize-superseded-markers.mjs \.

Borrowing it

Nothing to install: this file belongs to kurone-kito/idd-skill. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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 C, and why

idd-skill idd-review-snapshot.instructions.md scanned grade C 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 4d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 273 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IDD — Review Snapshot Phase (E1–E3)

Read this file after CI passes on a newly pushed PR, or after returning from a fix cycle. It covers fetching review items (E1), running the critique pass (E2), and checking whether ReviewItems_snapshot is empty (E3).

Before posting any E-phase operational comment or GitHub reply, apply the shared claim revalidation gate. The active claim must still use your current {claim-id} — this also serves as E1's phase-entry self-check: E1 re-fetches all of its state from GitHub on every entry, so, unlike B1/B3, there is no local plan or worktree artifact that could go stale between checks.

If ReviewItems_snapshot is empty after E3: proceed to the E-phase branch-sync check in idd-review-triage.instructions.md. If ReviewItems_snapshot is non-empty after E3: proceed to idd-review-triage.instructions.md (E4).

E1 — Fetch review items into ReviewItems_snapshot

Step 1 — Snapshot the activity universe. First, read the current PR HEAD SHA from the GitHub API and store it as {head-SHA}. Do not re-read the HEAD SHA during Steps 1–3; use this single stored value throughout. Then fetch all of the following from GitHub in a single pass (before applying any exclusion filters):

  • All review threads (resolved or not) — paginate until hasNextPage is false; do not stop at a fixed page size such as first: 20, as that would miss threads when the total count exceeds the page size
  • All review body submissions (any reviewer state)
  • All regular PR comments

Exclude trusted agent operational comments from the snapshot: comments whose body begins with one of these exact operational marker prefixes and whose GitHub author is a trusted marker actor per idd-overview-core.instructions.md:

  • <!-- review-watermark:
  • <!-- review-baseline:
  • <!-- claimed-by:
  • <!-- unclaimed-by:
  • advisory-wait:
  • advisory-wait-recovery:
  • <!-- advisory-wait:
  • advisory-reroll:

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.
