What it does
Repo Mirror Sources is an agent skill from netdata/netdata. Inspect Netdata-org source checkouts under NETDATAREPOSDIR, or set up and synchronize that mirror when requested. Use for cross-repo lookup, review, missing sources, mirror freshness, or scoped sync. Source inspection does not require syncing; maintenance can switch branches, pull, clone, and force-update submodules.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `how-tos/INDEX.md`, `maintenance.md` and `scripts/sync-netdata-repos.sh`).
It sits in DevOps & Cloud. It works with Git. The repository describes itself as: The fastest path to AI-powered full stack observability, even for lean teams. The licence is GPL-3.0.
When your agent uses it
- Cross-repo lookup
- Missing sources
- Mirror freshness
Example prompts
- “/repo-mirror-sources”
Requirements
- Python 3
- A Bash shell
What it can do on your machine
Read from SKILL.md and the folder at commit a7f3cf9. 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
Ships 2 files in scripts/ (Shell and Python), which the agent can run.
Shell commands in SKILL.md call:
gitrg
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, 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
Repo Mirror Sources loads about 1.2k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 513 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: notes
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); the scripts in this folder are not scanned.

- description
- Inspect Netdata-org source checkouts under NETDATA_REPOS_DIR, or set up and synchronize that mirror when requested. Use for cross-repo lookup, review, missing sources, mirror freshness, or scoped sync. Source inspection does not require syncing; maintenance can switch branches, pull, clone, and force-update submodules.
Netdata source mirrors
Use existing local source checkouts for cross-repo search and review. This Netdata-org mirror is independent of other
research mirrors. Its path is ${NETDATA_REPOS_DIR}; configuration is documented in .agents/ENV.md.
Choose the task
| Task | Read / do |
|---|---|
| Inspect, compare, or review source | Use the read-only route below; load relevant domain skills for the assigned lens |
| Establish whether local evidence is current enough | Record checkout revision/state and the question's required revision; do not assume local means latest |
| Set up, refresh, or troubleshoot the mirror | Read maintenance.md before any sync; apply the scope already authorized by the task |
| Understand helper behavior | Read scripts/sync-netdata-repos.sh; its checks are not a general preservation guarantee |
| Capture a reusable mirror procedure | Follow how-tos/INDEX.md and AGENTS.md#knowledge-capture |
A request for cross-repo grep or review does not authorize sync, checkout, fetch, pull, clone, stash, commit, or push. A task that already authorizes maintenance needs no repeated permission for the same scope. Prefer named repository updates for a narrow maintenance request; full organization discovery is a distinct scope.
Inspect existing source
Resolve only the required configured path; do not print unrelated environment values or load credentials to grep
local files. The helper reads an exported NETDATA_REPOS_DIR and does not source .env itself. Set it explicitly
from the trusted project configuration when needed; maintenance setup is in maintenance.md.
For a known checkout such as learn, inspect its state before using it as evidence:
: "${NETDATA_REPOS_DIR:?Set the configured mirror directory}"
mirror_repo="$NETDATA_REPOS_DIR/learn"
git --no-optional-locks -C "$mirror_repo" rev-parse HEAD
git --no-optional-locks -C "$mirror_repo" symbolic-ref --quiet --short HEAD || true
git --no-optional-locks -C "$mirror_repo" status --short --untracked-files=all --ignore-submodules=none
rg --files "$mirror_repo"Use rg on the relevant files after locating them. A blank branch result may mean detached HEAD; a failed Git
command is not a clean-state result. An available source checkout can be nested or use a .git file even though the
sync helper only recognizes immediate repositories with .git directories.
Record the upstream owner/repository and exact checked commit under AGENTS.md#open-source-reference-evidence.
Distinguish working-tree edits from committed source; do not attribute edited contents to an unmodified commit.
Existing sources can answer questions about their recorded revision without a refresh. Check the requested revision
when reviewing a PR or historical behavior; switching to default would discard the intended review context.
Show full SKILL.md (175 more words)Show less
If required sources are absent or freshness cannot be established, report that limit and determine whether the task
already authorizes a scoped refresh or acquisition. Do not silently run the full sync to resolve one missing checkout.
A current local timestamp, branch name, or old origin/HEAD reference does not prove live upstream freshness.
Maintenance boundary
The vendored helper performs existing-repository updates and optional organization discovery. It switches branches,
fetches/pulls, force-updates recursive submodules, and writes the mirror activity cache. --repo selects existing
repositories and disables discovery; it does not confine every side effect to those repositories.
Read maintenance.md for prerequisites, exact selection behavior, safety limits, and post-run checks. Help alone
requires neither configuration nor installed Git tooling:
.agents/skills/repo-mirror-sources/scripts/sync-netdata-repos.sh --helpNo scheduling automation is installed by this skill. A long absence, new repository, or periodic freshness requirement can justify an authorized maintenance task; none makes maintenance a prerequisite to every source read.
Path discipline
.agents/sensitive-data-discipline.md#allowed-alternatives owns path notation. Use ${NETDATA_REPOS_DIR} for mirror
paths in skills and evidence; do not embed personal workstation paths in this skill or its helper.
