/appsignal

Connect to AppSignal to monitor application performance, manage deploy markers, inspect error/performance samples and upload sourcemaps. Pure Ruby, zero gems — stdlib only.

Setup (check before using)

ruby ~/.claude/skills/appsignal/scripts/check_setup.rb

If the output is OK, proceed to the Flow section.

If the output is SETUP_NEEDED, guide the user step by step. Present ONE step at a time, wait for the user to confirm before moving to the next.

Step 1 — Ask the user to get their personal API key:

You need an AppSignal personal API key.

1. Go to https://appsignal.com/users/edit
2. Copy your Personal API token

Paste the API key here.

Step 2 — When the user pastes the key, save it:

ruby ~/.claude/skills/appsignal/scripts/save_token.rb 'PASTED_KEY'

If the script outputs an error, the key is invalid. Ask the user to double-check and try again.

If setup is not complete, DO NOT proceed to the Flow. Complete all steps first.

Flow

The argument $ARGUMENTS may contain an action or app id.

All endpoints require an app_id. Ask the user for it if not provided. The app_id is visible in AppSignal URLs (e.g. appsignal.com/org/sites/APP_ID).

Step 1: List markers to confirm connectivity

ruby ~/.claude/skills/appsignal/scripts/markers.rb APP_ID --limit 5

Present the markers and ask what the user wants to do.

Step 2: Actions

Get graph data:

ruby ~/.claude/skills/appsignal/scripts/graphs.rb APP_ID --timeframe day --fields mean,count
ruby ~/.claude/skills/appsignal/scripts/graphs.rb APP_ID --action "BlogPostsController-hash-show" --fields mean,pct --from "2025-01-01T00:00:00Z" --to "2025-01-02T00:00:00Z"
ruby ~/.claude/skills/appsignal/scripts/graphs.rb APP_ID --kind web --fields mean,count,ex_count,ex_rate

List markers:

ruby ~/.claude/skills/appsignal/scripts/markers.rb APP_ID
ruby ~/.claude/skills/appsignal/scripts/markers.rb APP_ID --limit 10 --kind custom
ruby ~/.claude/skills/appsignal/scripts/markers.rb APP_ID --from "2025-01-01T00:00:00Z" --to "2025-02-01T00:00:00Z"
ruby ~/.claude/skills/appsignal/scripts/markers.rb APP_ID --count_only true

Get marker details:

ruby ~/.claude/skills/appsignal/scripts/marker.rb APP_ID MARKER_ID

Create a deploy marker (requires user confirmation):

ruby ~/.claude/skills/appsignal/scripts/create_marker.rb APP_ID --kind deploy --repository "git@github.com:company/repo.git" --revision "abc123" --user "deployer"

Create a custom marker (requires user confirmation):

ruby ~/.claude/skills/appsignal/scripts/create_marker.rb APP_ID --kind custom --icon "🚀" --message "Released v2.0"

Update a marker (requires user confirmation):

ruby ~/.claude/skills/appsignal/scripts/update_marker.rb APP_ID MARKER_ID --message "Updated deploy note"

Delete a marker (requires user confirmation):

ruby ~/.claude/skills/appsignal/scripts/delete_marker.rb APP_ID MARKER_ID

List samples:

ruby ~/.claude/skills/appsignal/scripts/samples.rb APP_ID
ruby ~/.claude/skills/appsignal/scripts/samples.rb APP_ID --type performance --limit 5
ruby ~/.claude/skills/appsignal/scripts/samples.rb APP_ID --type errors --action "AccountsController-hash-index" --exception "NoMethodError"
ruby ~/.claude/skills/appsignal/scripts/samples.rb APP_ID --since 1374843246 --before 1374929646
ruby ~/.claude/skills/appsignal/scripts/samples.rb APP_ID --count_only true

Get sample details:

ruby ~/.claude/skills/appsignal/scripts/sample.rb APP_ID SAMPLE_ID

Upload a sourcemap (requires user confirmation):

ruby ~/.claude/skills/appsignal/scripts/upload_sourcemap.rb --push_api_key PUSH_KEY --app_name "MyApp" --environment production --revision "abc123" --name "https://example.com/app.min.js" --file /path/to/app.js.map

Notes

• Pure Ruby, zero gems — stdlib only (json, net/http, uri, fileutils)
• Auth via personal API token passed as ?token= query parameter
• Token file: ~/.config/appsignal/token (outside the repo, never commit)
• Base URL: https://appsignal.com/api
• All endpoints use .json suffix
• Action names must escape # → -hash-, / → -slash-, . → -dot-
• Sourcemap uploads use a different auth method (Push API key, not personal token)
• Creating, updating and deleting markers requires explicit user confirmation
• Uploading sourcemaps requires explicit user confirmation
