grackle: Skill for Claude Code

.claude/skills/set-blocked-by/SKILL.md

set-blocked-by is a skill for Claude Code from nick-pape/grackle. It costs 49 tokens per session (482 once invoked), scanned A, original, MIT.

A GitHub issue-dependency tool that marks one issue as blocked by another, or removes that relationship. A blocked issue is work that cannot proceed until another issue is handled.

In plain words
What is it for?
Use it to add or remove blocked-by relationships between two issues in the configured GitHub repository.
Why use it?
It makes task dependencies visible instead of leaving them in comments or private notes. This helps teams understand why work is waiting and what must happen first.

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

set-blocked-by 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 10d 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.

What it actually says

Set Blocked-By — GitHub Issue Dependency Relationships

Manages blocked-by (dependency) relationships between GitHub issues using the GraphQL API.

REPO_OWNER="nick-pape"
REPO_NAME="grackle"

Usage

  • /set-blocked-by <blocked#> <blocker#> — mark issue as blocked by another
  • /set-blocked-by remove <blocked#> <blocker#> — remove the blocked-by relationship

Step 1: Get Node IDs

Fetch node IDs for both issues:

gh api graphql -f query='
  query($owner: String!, $name: String!, $blocked: Int!, $blocker: Int!) {
    repository(owner: $owner, name: $name) {
      blocked: issue(number: $blocked) { id title }
      blocker: issue(number: $blocker) { id title }
    }
  }
' -f owner="$REPO_OWNER" -f name="$REPO_NAME" -F blocked=<BLOCKED_NUMBER> -F blocker=<BLOCKER_NUMBER>

Step 2: Mutate

Add blocked-by

gh api graphql -f query='mutation {
  addBlockedBy(input: {
    issueId: "<BLOCKED_NODE_ID>",
    blockingIssueId: "<BLOCKER_NODE_ID>"
  }) { issue { number title } }
}'

Remove blocked-by

gh api graphql -f query='mutation {
  removeBlockedBy(input: {
    issueId: "<BLOCKED_NODE_ID>",
    blockingIssueId: "<BLOCKER_NODE_ID>"
  }) { issue { number title } }
}'

Field names (easy to mix up):

  • issueId = the issue that is blocked
  • blockingIssueId = the issue that is blocking it

Step 3: Confirm

Report what was done: "Marked #blocked as blocked by #blocker" or "Removed blocked-by relationship between #blocked and #blocker."

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.
