What is meta-capi-signal-health?

A review of the tracking signals Meta uses to measure Facebook and Instagram advertising, including browser tracking, server-side events, event matching, attribution, and iOS app measurement.

Use it to check Conversions API coverage and deduplication, pixel events, Event Match Quality, Aggregated Event Measurement priorities, attribution settings, and iOS/SKAN coverage.

It helps reveal gaps, duplicate events, incorrect priorities, or weak signal quality that can affect Meta's measurement and optimization.

Per session 174 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00174	$0.00237
Opus 5.5	$0.00070	$0.00095
Sonnet 5.5	$0.00035	$0.00047
Haiku 4.5	$0.00017	$0.00024

Security

Grade A, and why

meta-capi-signal-health 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 2mo 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.

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.
