Wayback Machine Skill

Five tools wrapped via mcp-gateway. All anonymous; wayback_save optionally uses OREILLY_API_KEY-style auth via IA_ACCESS_KEY + IA_SECRET_KEY for the higher rate ceiling.

Decision tree

Q: "Is this URL archived?"            → fulcrum:wayback_availability
Q: "Show me snapshots of X over time" → fulcrum:wayback_cdx
Q: "Has this page changed?"           → fulcrum:wayback_cdx (collapse=digest)
Q: "Capture this URL now"             → fulcrum:wayback_save
Q: "What new items appeared?"         → fulcrum:internet_archive_changes
Q: "Pull the metadata of an item"     → fulcrum:internet_archive_metadata
Q: "Search the IA catalog"            → fulcrum:internet_archive_search
Q: "Upload/download with `ia` CLI"    → use sibling skill `ia`

High-leverage workflows

1. Patent-grade evidence locking (MIK-3344 line)

# Lock in adversarial-resistant proof at triage time
gateway_execute("fulcrum:wayback_save", {
  "url": "<source>",
  "capture_screenshot": "1",
  "if_not_archived_within": "1d"  # idempotent
})
# job returns; then 30 sec later:
gateway_execute("fulcrum:wayback_availability", {
  "url": "<source>",
  "timestamp": "<job-time>"
})
# returns court-admissible Wayback URL with timestamp

2. Paper-revision detection across prior-art portfolio (MIK-3355)

# Weekly diff for each tracked arxiv paper:
rows = gateway_execute("fulcrum:wayback_cdx", {
  "url": "arxiv.org/abs/<id>",
  "collapse": "digest",       # one row per unique content hash
  "from": "<last-check-ts>",
  "output": "json"
})
# different digest = paper was revised; alert + re-read body

Operational contract:

1. Keep the tracked paper list in

~/.claude/data/portfolio/cdx_paper_diff_config.json.

1. Run ~/.claude/data/portfolio/cdx_paper_diff.py weekly. The script

calls fulcrum:wayback_cdx via the local mcp-gateway CLI using collapse: "digest" and from: <last-check-ts> for each configured arXiv ID.

1. Persist state in ~/.claude/data/portfolio/cdx_paper_diff_state.json.

First run is a baseline and must not alert on newly observed digests.

1. On later runs, a digest change emits a Linear comment on the configured

patent/prior-art ticket. If a paper is intentionally untracked, enable linear.create_untracked in the config to file a new MIK ticket.

1. Schedule manifest:

~/.claude/data/portfolio/cdx_paper_diff_schedule.json uses cron expression 0 9 * * 1 (Mondays 09:00 UTC, Mondays 12:00 Helsinki during UTC+03) for remote-agent scheduling.

1. If failed_or_empty / papers exceeds max_error_rate (default 5%),

treat the run as needing fallback to slower per-paper wayback_availability probes before trusting the weekly digest gate.

3. Link-rot prophylaxis at URL-triage

Wire into url-insight skill: every fetched URL also gets wayback_save({if_not_archived_within: "7d"}). Cheap insurance against rot.

4. Forensic timeline of a domain

gateway_execute("fulcrum:wayback_cdx", {
  "url": "<competitor.com>",
  "matchType": "host",
  "filter": "statuscode:200,mimetype:text/html",
  "collapse": "timestamp:8",   # one snapshot per day
  "limit": 100
})

Auth tiers

Keys live in ~/.claude/secrets.env + ~/.mcp-gateway/.env + 1Password "Claude Elite" → "Internet Archive S3 Keys". Recovery: op item get "Internet Archive S3 Keys" --vault="Claude Elite" --fields username,credential --reveal

Confidence levels

V (verified ≥2 sources): all 5 tools pass live smoke tests 2026-05-04 against gateway commit 24ea7b31. Live trace IDs: gw-a6b8578b… (auth), gw-beac5e7c… (search), gw-f84d661d… (auth save).

Composition cross-links

• Upstream: url-insight (auto-snapshot URLs at triage)
• Downstream: linear (file evidence URL on patent tickets)
• Sibling: ia (CLI-based upload/download via internetarchive

package — installed via internet-archive-skills plugin)

• Replaces: nothing — pure additive layer

Versioning

• 2026.05.05 — initial 5-tool wrap. CDX digest-diff workflow validated.
