one command, takes just this skill from the repositorynpx skills add https://github.com/DataDog/pup --skill dd-symdbThe instruction itself
12 sections, as written by the authorDatadog Symbol Database
Search for classes and methods in instrumented services. Find probe-able method locations for use with the Live Debugger.
Prerequisites
pup must be installed:
brew tap datadog-labs/pack && brew install pup
Authentication
Authenticate via OAuth2 (recommended) or API keys:
# OAuth2 (recommended)
pup auth login
# Or use API keys
export DD_API_KEY="key" DD_APP_KEY="key" DD_SITE="datadoghq.com"
Usage
Names View
One scope name per line.
pup symdb search --service my-service --query "Controller" --view names
Probe Locations View
TYPE:METHOD(arg1, arg2, ...) signatures suitable for --probe-location in pup debugger probes create. Falls back to TYPE:METHOD when no argument info is available.
pup symdb search --service my-service --query "VetController" --view probe-locations
Full View
Raw JSON response from the API.
pup symdb search --service my-service --query "VetController" --view full
Filter by Version
pup symdb search --service my-service --query "handler" --version "v1.2.3" --view names
Combining with Debugger
Find methods then place probes:
# 1. Find probe-able methods
pup symdb search --service my-service --query "MyController" --view probe-locations
# 2. Place a probe on a discovered method (language auto-detected from symdb)
pup debugger probes create \
--service my-service \
--env production \
--probe-location "com.example.MyController:handleRequest" \
--template "handleRequest called with id={id}"
# Or use the full signature when multiple overloads exist
pup debugger probes create \
--service my-service \
--env production \
--probe-location "com.example.MyController:handleRequest(int, java.lang.String)" \
--template "handleRequest called with id={id}"
# 3. Stream events
pup debugger probes watch <PROBE_ID> --timeout 60 --limit 10
Options
| Flag | Description | Default |
|------|-------------|---------|
| --service | Service name (required) | — |
| --query | Search query, matches scope names | None (lists all) |
| --version | Service version filter | None |
| --view | Output view: full, names, probe-locations | full |
Failure Handling
| Problem | Fix |
|---------|-----|
| No results | Verify the service is instrumented and reporting to Datadog |
| Auth error | Run pup auth login or set DD_API_KEY + DD_APP_KEY + DD_SITE |
| Wrong service name | Check exact service name in Datadog APM service catalog |
| Stale symbols | Filter with --version to target the currently deployed version |

How to use it
Take datadog/dd-symdb from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference brew.
Without those the skill loads but fails at the first command.
