Overview

GitHub Issues has only two states: open and closed. To express the canonical defect lifecycle (bug-lifecycle-reference) teams supplement Issues with labels (severity, priority, status) and optionally Projects v2 (status columns).

This skill wraps the GitHub Issues REST API (per docs.github.com/en/rest/issues/issues) for create / update / close / reopen / search, and notes the Projects v2 GraphQL augmentation when richer state is needed. Version-sensitive facts are collected under API version.

When to use

• Filing a bug from a CI test failure on a GitHub-hosted project (consumed by bug-report-from-failure).
• Maintaining bug label / status discipline in an open-source project where GitHub Issues is the canonical tracker.
• Backing duplicate-defect search for GitHub-using teams.

How to use

1. Authenticate with a token and pin the API version via the X-GitHub-Api-Version header (see Authentication).
2. Before filing, search open label:bug issues by title to dedupe (see Search).
3. Create the issue with severity / priority / status labels; express lifecycle via labels + state_reason on close (see Label conventions / State transitions).
4. Add Projects v2 columns, drive the gh CLI, or wire CI - all in references/github-issues-reference.md.

Authentication

Per GitHub REST API docs:

export GITHUB_TOKEN="ghp_..."  # personal access token, classic or fine-grained
export GITHUB_REPO="owner/repo"

import requests, os

HEADERS = {
    "Authorization": f"Bearer {os.environ['GITHUB_TOKEN']}",
    "Accept": "application/vnd.github+json",
    "X-GitHub-Api-Version": "2026-03-10",
}
BASE = f"https://api.github.com/repos/{os.environ['GITHUB_REPO']}"

API version

Version-sensitive facts, kept in one place so time-bound detail does not leak through the rest of the doc:

• Pin X-GitHub-Api-Version: 2026-03-10 (set in the Authentication headers above) to lock the response shape.
• Omitting the header defaults to 2022-11-28, the older of the two supported versions (per docs.github.com/en/rest/about-the-rest-api/api-versions).
• The type field on issue creation is recently added for issue types and is not universally supported across all clients yet.

Create an issue

POST /repos/{owner}/{repo}/issues per the API docs:

def create_bug(title, body, severity, priority, labels=None):
    payload = {
        "title": title,
        "body": body,
        "labels": (labels or []) + [
            "bug",
            f"severity:{severity}",
            f"priority:{priority}",
        ],
    }
    r = requests.post(f"{BASE}/issues", json=payload, headers=HEADERS)
    r.raise_for_status()
    return r.json()

Required parameter is title. Optional: body, assignees, milestone, labels, type (see API version).

Label conventions

Since GitHub has no first-class severity / priority field, teams adopt label prefixes:

Adopt them consistently - defect-report review checks that severity + priority labels are both present.

State transitions via PATCH

PATCH /repos/{owner}/{repo}/issues/{issue_number}. The state_reason parameter (per API docs) takes completed | not_planned | reopened | duplicate:

def close(issue_number, reason="completed"):
    """reason: completed | not_planned | duplicate"""
    r = requests.patch(
        f"{BASE}/issues/{issue_number}",
        json={"state": "closed", "state_reason": reason},
        headers=HEADERS,
    )
    r.raise_for_status()
    result = r.json()
    # verify the destructive transition landed; a stale state means a concurrent edit won
    assert result["state"] == "closed" and result["state_reason"] == reason, result
    return result

def reopen(issue_number):
    r = requests.patch(
        f"{BASE}/issues/{issue_number}",
        json={"state": "open", "state_reason": "reopened"},
        headers=HEADERS,
    )
    r.raise_for_status()
    return r.json()

Map canonical lifecycle states via labels + close-reason:

Search

GET /repos/{owner}/{repo}/issues supports filter via query parameters; for richer search use the search endpoint:

def search_issues(q):
    r = requests.get(
        "https://api.github.com/search/issues",
        params={"q": f"repo:{os.environ['GITHUB_REPO']} {q}"},
        headers=HEADERS,
    )
    r.raise_for_status()
    return r.json()["items"]

dupes = search_issues(
    f'type:issue is:open label:bug "{title_safe}" in:title,body'
)

GitHub search has a 30-request-per-minute unauthenticated / higher authenticated rate limit.

Comments

POST /repos/{owner}/{repo}/issues/{issue_number}/comments:

def add_comment(issue_number, body):
    r = requests.post(
        f"{BASE}/issues/{issue_number}/comments",
        json={"body": body}, headers=HEADERS)
    r.raise_for_status()
    return r.json()

Worked example

File a bug from a CI failure idempotently: search for an open duplicate first, comment on it if found, otherwise create a new labelled issue. This reuses search_issues, add_comment, and create_bug above:

def create_or_attach(title, body):
    dupes = search_issues(f'is:open label:bug "{title}" in:title')
    if dupes:
        add_comment(dupes[0]["number"], f"Recurred: {body[:500]}")
        return dupes[0]["number"]
    issue = create_bug(title, body, severity="medium", priority="p3")
    return issue["number"]

# From a failing pytest run:
num = create_or_attach(
    "Checkout fails for promo X",
    "<repro>\n1. Apply promo X\n2. Checkout 500s\n</repro>",
)
print(f"Bug tracked as #{num}")

Verify: search_issues ranks by relevance and can return near-misses, so before attaching to or bulk-closing a hit, assert its title matches the target; skip and log any that do not rather than commenting on or closing the wrong issue, then re-run the dedupe against the corrected query.

The create response includes number (per-repo), html_url (permalink), and node_id (GraphQL ID for Projects v2 cross-ref). Moving the issue across a Projects v2 status column, the gh CLI equivalents, and CI wiring are in references/github-issues-reference.md.

Anti-patterns

Limitations

• Open / closed only. Rich lifecycle expressed via labels + Projects requires team discipline; the API doesn't enforce it.
• No native severity / priority fields. Conventions vary across orgs - the runner is portable only if the team adopts the label vocabulary above.
• Projects v2 is GraphQL. REST + GraphQL hybrid; engineers need both.
• Cross-repo dedupe. GitHub Issues are per-repo; cross-repo duplicate detection needs Search API with org: qualifier.
