greptimedb: Skill for Codex

.agents/skills/greptimedb-release-note/SKILL.md

greptimedb-release-note is a skill for Codex from GreptimeTeam/greptimedb. It costs 70 tokens per session (2,733 once invoked), scanned A, original, Apache-2.0.

A release-note workflow for GreptimeDB, a time-series database. It uses the project's commit history and GitHub pull requests to prepare a changelog and a documentation blog pull request.

In plain words
What is it for?
Use it to create a GreptimeDB release changelog, account for already released patch pull requests, rebuild the contributor list, add selected highlights, save the result, and prepare the docs change.
Why use it?
It helps avoid incorrect version ranges, duplicate entries, missing contributors, and changelog details that still need human review.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: positional $N argument; installed under .agents/ (shared by several agents).

This is GreptimeTeam/greptimedb's own configuration. It tells Codex how to work on greptimedb 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 greptimedb configures →

About the project

GreptimeDB is an observability database that stores metrics, logs, and traces in a columnar engine over object storage, using a shared table model for the data. It is for operating telemetry backends, correlating related signals with SQL, and querying metrics with PromQL.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 181
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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

greptimedb-release-note 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 13d 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.

GreptimeDB Release Note / Changelog

Generate the changelog for a GreptimeDB release. Tooling: git cliff (config: cliff.toml in the greptimedb repo) and gh. Run inside the greptimedb checkout.

Prerequisites: git cliff, gh (check gh auth status), and Python (the subtract-PRs / rebuild-contributors step in §3–§4 is scripted). This skill writes <remote> for the git remote pointing at GreptimeTeam/greptimedb (often upstream, sometimes origin); resolve it with git remote -v | grep -i 'GreptimeTeam/greptimedb' | awk '{print $1}' | head -1.

1. GitHub token (never print it)

git cliff enriches commits with PR titles/authors via the GitHub API; for hundreds of commits you need a token or you hit rate limits. Pass it inline and never read or echo the token:

GITHUB_TOKEN=$(gh auth token) git cliff ...

Alternatively the user sources an env file that exports GITHUB_TOKEN (don't read it). Without a token it still runs, but may be rate-limited / incomplete.

2. Determine the previous version (skip nightlies)

From gh release list --repo GreptimeTeam/greptimedb, ignore *-nightly-*, -rc.*, -beta.*, and build-suffixed tags; focus on formal vX.Y.Z.

  • Patch vX.Y.Z (Z>0): previous = vX.Y.(Z-1).
  • New minor vX.Y.0: previous = the latest vX.(Y-1).* (for v1.0.0, the biggest 0.x). Double-check with the user.

3. Pick the range and generate

Key topology fact: a minor tag (e.g. v1.0.0) is an ancestor of main; patch tags (v1.0.1, v1.0.2) live on the release/v1.0 branch and are NOT ancestors of main (they are cherry-picks with different SHAs). Verify with git merge-base --is-ancestor <tag> <remote>/main.

New minor (X.Y.0, cut from main)

Note the two different tags here: the git cliff base is the previous minor .0 tag (e.g. v1.0.0, an ancestor of main) — not the "previous version" from §2 (the latest patch, e.g. v1.0.2), which is only used below to decide which patch PRs to subtract.

Changes

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.
