What it does
Cws Btfhub Sync is an agent skill from DataDog/datadog-agent, published by the product's own GitHub organization. Sync CWS BTFHub constants after adding a new constantfetch offset, so pre-BTF kernels can resolve it. Use when KMT secagent jobs log "failed to fetch constant for <name".
Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Main repository for Datadog Agent. The licence is Apache-2.0.
When your agent uses it
- KMT secagent jobs log failed to fetch constant for <name
Example prompts
- “failed to fetch constant for <name”
- “/cws-btfhub-sync”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Bash, AskUserQuestion
What it can do on your machine
Read from SKILL.md and the folder at commit a706f1a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepBashAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gh
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.
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
Cws Btfhub Sync loads about 600 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 265 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

The automated check noted patterns worth knowing about, such as sudo or a known installer.

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.

Syncing CWS BTFHub constants
A new appendOffsetofRequest in probe_ebpf.go resolves via BTF on modern kernels, but
pre-BTF kernels read the offset from the checked-in, arch-split constants:
pkg/security/probe/constantfetch/constants_amd64.jsonpkg/security/probe/constantfetch/constants_arm64.json
These predate your change and so lack the new entry. Regenerating them is the fix.
Run it
gh workflow run cws-btfhub-sync.yml --ref main -f base_branch=<your-feature-branch>The trap: --ref selects the workflow definition — keep it main. base_branch is the
ref the generate and combine jobs check out, and the base of the PR it opens. Leave
base_branch at its main default and the generator never sees your new offset requests: the
sync yields an empty diff and it looks like btfhub simply lacks the offsets.
Before running, confirm the failing distros are covered by the cone matrix in
.github/workflows/cws-btfhub-sync.yml.
Wait for it
It is a ~15-job matrix and takes tens of minutes. Poll it from a background shell so the wait costs nothing and you get re-invoked on exit:
until [ "$(gh run view <run-id> --json status -q .status)" = completed ]; do sleep 60; done
gh run view <run-id> --json conclusion -q .conclusionDo not run gh run watch in the foreground (it outlives the tool timeout) and do not chain
short sleeps in the main loop. When the notification arrives, carry straight on to Land it
in the same turn — this is one task, not a hand-off.
Land it
On success the workflow opens a PR titled CWS: sync BTFHub constants from a
cws/constants-sync-* branch, targeting your branch:
gh pr list --search "CWS: sync BTFHub constants" --state open --json number,baseRefName,urlFrom the list, select the <number> that has the baseRefName equal to this feature branch and
merge it directly (gh pr merge <number> --merge); feature branches carry no protection rule,
so this needs no approval.
Confirm the merged commit touches btfhub/constants.json and that your new offset names appear
in the diff.
