validate_telemetry

A telemetry validation command for checking whether an application's observability data reaches the local Aspire dashboard. Telemetry is diagnostic information such as traces, metrics, and logs.

In plain words
What is it for?
Use it for either specification-based telemetry checks or a general health check, depending on whether the supplied file exists in `thoughts/shared/telemetry/`.
Why use it?
It catches missing dashboard access or export configuration before deeper validation, and reports problems without silently changing code or configuration.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

validate_telemetry scanned grade A with 1 finding 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 3d 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.

What it actually says

Validate Telemetry

Activate the observability-driven-development skill and run its Validation section.

Mode Detection

  • If an argument was provided and it resolves to an existing file under thoughts/shared/telemetry/, run Mode A — Spec-Driven Validation.
  • Otherwise (no argument, or argument doesn't resolve), run Mode B — Generic Health Check.

Pre-Flight

Before running either mode, confirm:

  1. The local Aspire dashboard is reachable (curl -sf http://localhost:18888 returns 2xx).
  2. The user's service is configured to export to the dashboard (OTEL_EXPORTER_OTLP_ENDPOINT set).

If either fails, surface a one-line setup hint pointing at observability-driven-development/local-setup.md and stop.

Output

Per the report format in the ODD skill's Validation section. Don't modify code or config silently — the report is the output.

Changes

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.

validate_telemetry is a command published in the GitHub repository adrielp/ai-engineering-harness (20 stars, last pushed 2mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 255 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
