What it does
Write Changelog is an agent skill from DataDog/dd-trace-rb, published by the product's own GitHub organization. Use when a change in this repo needs a customer-facing changelog entry — e.g. "add a changelog entry" — or when an approved PR that changes user-visible behavior in lib/, ext/, or docs/GettingStarted.md is about to merge.
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Changelog and release notes. It works with Datadog and Ruby. The repository describes itself as: Datadog's client library for Ruby.
When your agent uses it
- A change in this repo needs a customer-facing changelog entry — e.g
- Tasks that involve Changelog and release notes
Example prompts
- “add a changelog entry”
- “/write-changelog”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- bundle exec rake unreleased:lint and bundle exec rake unreleased:vale —
- bundle exec rake unreleased:render — check the rendered entry
- Re-run the Grounding triage against the final diff — effect, count,
What it can do on your machine
Read from SKILL.md and the folder at commit 10bb407. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
bundle
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Write Changelog loads about 2.9k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 1,175 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,175 words (~2,857 tokens).
“READ unreleased/README.md FIRST — it is the human-facing description of the fragment system and its fields. This skill is the agent-facing checklist.”
