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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00338 |
| Opus 5.5 | $0.00017 | $0.00135 |
| Sonnet 5.5 | $0.00008 | $0.00068 |
| Haiku 4.5 | $0.00004 | $0.00034 |
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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
1. The local Aspire dashboard is reachable (`curl -sf http://localhost:18888` 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:
- The local Aspire dashboard is reachable (
curl -sf http://localhost:18888returns 2xx). - The user's service is configured to export to the dashboard
(
OTEL_EXPORTER_OTLP_ENDPOINTset).
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.
Relationship to Other Commands

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 skill published in the GitHub repository adrielp/ai-engineering-harness (22 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 42 tokens to every session and 338 once invoked, about $0.0002 per session on Opus 5.5. 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.
