dd-apm

A Datadog application-performance tool for viewing traces, services, dependencies, and performance data. Distributed tracing follows a request as it moves through multiple services.

In plain words
What is it for?
Use it to list service statistics, operations, endpoints, dependencies, flow maps, and matching traces.
Why use it?
It helps show where requests slow down and how services interact in production or other environments.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dd-apm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Datadog APM

Distributed tracing, service maps, and performance analysis.

Requirements

Datadog Labs Pup should be installed via:

brew tap datadog-labs/pack
brew install pup

Quick Start

pup auth login
pup apm services list --env production
pup traces search --query="service:api-gateway" --from="1h"

Services

List Services

--env is required for all apm services commands.

pup apm services list --env production
pup apm services list --env staging

Service Statistics

pup apm services stats --env production
pup apm services stats --env production --from 4h

Service Operations and Resources

# List operations for a service
pup apm services operations --env production --service api-gateway

# List resources (endpoints) for an operation
pup apm services resources --env production --service api-gateway --name http.request

Service Dependencies

pup apm dependencies list --env production

Flow Map

# View service flow map (--query and --env required)
pup apm flow-map --query "service:api-gateway" --env production

Traces

Traces are searched via the top-level traces command (not under apm).

Important: APM durations are in nanoseconds: 1 second = 1,000,000,000 ns.

Search Traces

# By service
pup traces search --query="service:api-gateway" --from="1h"

# Errors only
pup traces search --query="service:api-gateway status:error" --from="1h"

# Slow traces (>1 second = 1000000000 ns)
pup traces search --query="service:api-gateway @duration:>1000000000" --from="1h"

# With specific tag
pup traces search --query="service:api @http.url:/api/users" --from="1h"

Aggregate Traces

# Average duration by resource
pup traces aggregate \
  --query="service:api-gateway" \
  --compute="avg(@duration)" \
  --group-by="resource_name" \
  --from="1h"

# Error count by service
pup traces aggregate \
  --query="status:error" \
  --compute="count" \
  --group-by="service" \
  --from="1h"

# p99 latency
pup traces aggregate \
  --query="service:api-gateway" \
  --compute="percentile(@duration, 99)" \
  --from="1h"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dd-apm is a skill published in the GitHub repository DataDog/pup (999 stars, last pushed 4d ago), licensed Apache-2.0. It adds 16 tokens to every session and 1,567 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
