explain-lading-configExplains a lading.yaml config file from the regression test suite, using the lading Rust source as ground truth for field meanings and defaults.
Explain Lading Config is an agent skill from DataDog/datadog-agent, published by the product's own GitHub organization. Explains a lading.yaml config file from the regression test suite, using the lading Rust source as ground truth for field meanings and defaults.
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 and reference files (for example `references/explanation-template.md`, `references/source-reading.md` and `scripts/resolve-lading-config.sh`).
It sits in Testing & QA. It works with Rust. The repository describes itself as: Main repository for Datadog Agent. The licence is Apache-2.0.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 20eff25. It shows what the files ask for, not the result of running them.
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.
Ships 2 files in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
bashyqgitFrom the folder's file list and the shell code blocks in SKILL.md.
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.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Explain Lading Config loads about 1.2k tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 516 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.
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); the scripts in this folder are not scanned.

.claude/skills/explain-lading-config/SKILL.md (or your agent's skills folder). This skill also uses 4 other files; get the full folder from GitHub.Explain what a lading regression test config does, grounded in lading source code.
# 1. Verify the lading checkout exists and is on a known branch
bash .agents/skills/explain-lading-config/scripts/validate-lading-checkout.sh
# 2. Resolve $ARGUMENTS to a lading.yaml path (exact/substring/glob/path)
bash .agents/skills/explain-lading-config/scripts/resolve-lading-config.sh "$ARGUMENTS"
# 3. Read the resolved file, then ground every field in lading source
# (see references/source-reading.md for the full strategy).
# 4. Write up the explanation following references/explanation-template.md.Defaults must be resolved to concrete values, not function names. Full workflow below.
Run .agents/skills/explain-lading-config/scripts/validate-lading-checkout.sh.
main, warn
the user that explanations are grounded in a non-main branch, then continue.git clone command on stderr.
Relay that to the user and stop.Override the checkout location with LADING_DIR if needed.
Use .agents/skills/explain-lading-config/scripts/resolve-lading-config.sh to
avoid ad-hoc matching. The script enumerates experiments under
test/regression/cases/ (active) and test/regression/x-disabled-cases/
(disabled). Each experiment is a <case>/lading/lading.yaml addressed by its
case-directory name; disabled rows are flagged with a trailing (disabled)
column in the listing. ebpf/cases/ (split-mode) and
ebpf/config-only/cases/ are intentionally out of scope; if a user asks about
one, tell them this skill doesn't cover it yet.
The script handles path-like inputs, substring case names, and shell
globs (*, ?).
If $ARGUMENTS is provided: run resolve-lading-config.sh "$ARGUMENTS".
AskUserQuestion to pick one, then read that
path.i can match 20+): do not
try to force them into AskUserQuestion. Print the experiment names
as a short bulleted list and ask the user to narrow the query and
re-invoke /explain-lading-config <name>.AskUserQuestion (up to
4 options) or as a short list; if not, relay the error and stop.cd into the repo.If the resolved path contains /x-disabled-cases/, flag this explicitly
in the explanation — the experiment exists on disk but is not currently
executed by SMP. Otherwise a user may assume it's live.
Reading very large configs: multi-sender configs (e.g.
uds_dogstatsd_20mb_12k_contexts_20_senders, ~870 lines) are usually
block-copies of one template with a few fields varying (typically only
seed). Before a full Read, check size and duplication:
wc -l <path> # scale check
grep -c '^ - ' <path> # top-level list entries
yq '.generator | length' <path> 2>/dev/null # if yq is presentFor highly-duplicated configs, Read only the first block (plus the
blackhole/target_metrics sections) and report the generator as
"N identical copies, seed differs" instead of walking every block. Spot-
check one later block to confirm uniformity.
If $ARGUMENTS is omitted: run resolve-lading-config.sh with no
argument. It emits <experiment>\t<path> lines for every discovered config.
Print the experiment names as a plain bulleted list to the user (preserving
the (disabled) markers) and ask them to type the name (or re-invoke the
skill with /explain-lading-config <name>).
Before explaining, read the lading source files that ground the populated
sections of the config. The detailed strategy (variant-to-module mapping,
grep-before-Read invariants, fallback for renamed files) lives in
references/source-reading.md — read it now.
Write the explanation following the structure in
references/explanation-template.md (generator summary, aggregate load,
blackhole sinks, target metrics, source references). Read it now.

Explain Lading Config is an agent skill from DataDog/datadog-agent, published by the product's own GitHub organization.yaml config file from the regression test suite, using the lading Rust source as ground truth for field meanings and defaults.
Explain Lading Config fits situations like: testing & QA work in your project.
Run `npx skills add DataDog/datadog-agent --skill explain-lading-config -a claude-code`. Or copy the skill folder (.agents/skills/explain-lading-config in DataDog/datadog-agent) into .claude/skills/explain-lading-config in your project. Claude Code loads it when a task matches its description.
Run `npx skills add DataDog/datadog-agent --skill explain-lading-config -a codex`. Or copy the skill folder (.agents/skills/explain-lading-config in DataDog/datadog-agent) into .agents/skills/explain-lading-config in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add DataDog/datadog-agent --skill explain-lading-config -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/explain-lading-config, .gemini/skills/explain-lading-config, .github/skills/explain-lading-config and .opencode/skills/explain-lading-config in your project.
Going by SKILL.md and its folder, Explain Lading Config needs a shell for the scripts in its folder and the command-line tools its instructions call (bash, yq and git). Our summary lists: A Bash shell.
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Explain Lading Config is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.7k tokens, read only when the agent opens those files.
