What it does
Eas Observe is an agent skill from sickn33/agentic-awesome-skills. Curated upstream guidance for Eas Observe; use when the workflow matches the user goal.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `agents/openai.yaml`, `references/metrics.md` and `references/queries.md`).
It sits in Mobile. It works with Expo. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- The workflow matches the user goal
Example prompts
- “/eas-observe”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npxeas
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.expo.devexpo.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Eas Observe loads about 1.3k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 25 tokens; SKILL.md has 541 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

EAS Observe
EAS service - costs apply. EAS Observe is an Expo Application Services product. The free EAS plan allows up to 10,000 monthly active users, with a limited set of features; higher usage requires a paid subscription. For details, see https://expo.dev/pricing#plan-features.
EAS Observe tracks startup, navigation, and custom-event performance from production Expo apps. It needs a development or production build — the native library is not in Expo Go.
Source of truth: https://docs.expo.dev/eas/observe/ — always consult the canonical docs when API details matter, especially get-started, configuration, integrations, and the metrics reference. EAS Observe is evolving; this skill's references are written to stay accurate but may lag the docs.
Which reference to read
The four reference files in ./references/ cover what people typically need this skill for:
- Adding EAS Observe to a project → [
./references/setup.md]. Install, wrap the root layout (AppMetricsRooton SDK 55,ObserveRooton SDK 56+), mark the app interactive (globalmarkInteractive()on SDK 55, theuseObserve()hook or<ObserveInteractiveMarker />on SDK 56+), optional per-route navigation metrics through the Expo Router / React Navigation integrations, user-defined events viaObserve.logEvent(SDK 56+), error reporting, and runtime configuration (sampling, dispatch, environments, custom endpoint). - Querying metrics from the terminal → [
./references/queries.md]. The sixeas observe:*commands —metrics-summary,metrics,routes,events,session,versions— with flags, metric aliases, table layouts, JSON shapes, and common workflows. - Reading a dashboard or CLI output → [
./references/metrics.md]. Target thresholds per metric, what the automatic TTI params mean (frameRate.*,device.*,network.*), and diagnostic patterns for telling slow-but-smooth startup apart from main-thread contention, hard blocks, or throttled devices. - Shipping an Observe integration in a library → [
./references/third-party.md]. For package authors only (SDK 57+): optional peer dependency, config declaration merging,Observe.registerIntegration(), and event naming.

Known gaps between the docs and the shipped code
Verified against eas-cli 21.8.0 and expo-observe 57.0.9. Trust this skill's references over the docs on these points, but re-check with --help and the installed package before relying on them:
- All six CLI commands are on the Querying with EAS CLI page. Older doc builds list only four and omit
observe:routesandobserve:session. - Navigation metric aliases are
nav_cold_ttr,nav_warm_ttr, andnav_tti. There are no barecold_ttr/warm_ttraliases in the CLI. - Sorting uses
--sort <slowest|fastest|newest|oldest>. There is no--orderflag. ObserveErrorBoundary,Observe.reportError, andconfigure({ errorHandlingEnabled })are exported but undocumented. Observe still has no crash reporting; use Sentry or BugSnag for that.
Submitting Feedback
If you encounter errors, misleading or outdated information in this skill, report it so Expo can improve:
npx --yes submit-expo-feedback@latest --category skills --subject "eas-observe" "<actionable feedback>"Only submit when you have something specific and actionable to report. Include as much relevant context as possible. If an AI agent repeatedly failed or the user had to take over an Expo task, load the expo-skill-feedback skill and follow its eval-candidate flow instead of reusing the command above.
Examples
User: Apply this skill to my current task.
Assistant: Follow the workflow in this skill, cite limitations, and ask before risky steps.Limitations
- Imported upstream skill; verify credentials, permissions, and safety boundaries before execution.
- Does not replace environment-specific validation, testing, or maintainer review.
