grep-continue

name	grep-continue
description	Continue an existing Grep research job with a follow-up question, building on the prior job's findings without re-running the entire investigation. Use when the user says "follow up on that research", "continue the X investigation", "go deeper on the third finding", or references a previous job by id/slug ("continue grep.ai/research/foo-bar-baz with: ...").

Continue an Existing Research Job

Submits a follow-up against a completed Grep job — re-runs inference at the user's chosen effort tier, but inherits the prior job's research context so it doesn't re-investigate the same ground. Cheaper and faster than starting fresh when the new question genuinely builds on the old one.

When to use this skill vs the others

User wants	Use
New, unrelated research	/research, /quick-research, /grep-domain-expert
Follow-up on a previous job	/grep-continue (you are here)
Multi-step end-to-end (orient → deep → build)	/grep-research-workflow (uses --reference-jobs= programmatically)
Build a different artifact from the same research	/grep-continue <slug> "..." --output-type=... (this skill, with output_type)

Concrete signals: "follow up on that", "continue the X investigation", "go deeper on the third finding", "now make me a deck from that", "what about Y based on the previous research", "that report you just did, but for region Z". Especially when the user references a previous job by slug or URL.

Auto-update check

node "$SCRIPTS_DIR/update-check.js" 2>/dev/null &

Prerequisites

node "$SCRIPTS_DIR/auth.js" status

If "authenticated": false, automatically invoke /grep-login.

Continue costs the same as a fresh job at the same effort tier ($2 for medium, $10 for high, $2 for build). The savings come from inheritance — the model spends its budget on the new question instead of re-establishing context.

Resolve script path

SCRIPTS_DIR="$(dirname "$(dirname "$(dirname "$(readlink -f "${CLAUDE_SKILL_DIR}/SKILL.md")")")")/scripts"

Step 1: Resolve the parent job

The user can refer to the parent in three forms — extract the id_or_slug from any of them:

1. UUID: b19421e9-1234-5678-9abc-def012345678
2. Slug: anthropic-revenue-strategy-2026
3. URL: https://grep.ai/research/anthropic-revenue-strategy-2026 — strip the path prefix

# Extract from URL or accept slug/UUID directly
PARENT="${1:-}"
PARENT="${PARENT##*/research/}"  # strip URL prefix if present
PARENT="${PARENT%%\?*}"            # strip query string
PARENT="${PARENT%%\#*}"            # strip URL fragment (e.g. #third-finding)

If the user didn't provide a slug/UUID, look at recent conversation. If still ambiguous, ask:

Header: "Which job?" Question: "Which prior research job should I continue?" Options: list any slugs/UUIDs from recent conversation, plus "List my recent jobs" (which runs node grep-api.js jobs)

Step 2: Verify the parent exists and is complete

STATUS=$(node "$SCRIPTS_DIR/grep-api.js" status "$PARENT" \
  | node -e "let d='';process.stdin.on('data',c=>d+=c).on('end',()=>{const j=JSON.parse(d);process.stdout.write(j.status||'')}")
case "$STATUS" in
  completed|complete)
    : # OK
    ;;
  running|pending|queued)
    echo "Job is still running. Wait for it to complete before continuing."
    exit 1
    ;;
  failed|cancelled)
    echo "Job is in '$STATUS' state — can't continue. Start a fresh job."
    exit 1
    ;;
  *)
    echo "Unexpected status: $STATUS"
    exit 1
    ;;
esac

The API will 422 on a failed or cancelled parent. Better to fail fast with a clear message than to surface a confusing API error.

Step 3: Refine the follow-up question

The user's raw follow-up is often terse ("go deeper on the third finding"). Refine it:

• Reference the parent topic explicitly so the new job's report stands on its own
• Cite the specific finding/section/entity from the parent that the user is building on
• Mention any new constraints (different region, different time range, narrower scope)

Example:

• Raw: "go deeper on the third finding"
• Refined: "Deeper investigation on the third finding from the prior Anthropic enterprise strategy research — specifically, the SOC2 compliance signal as a moat against open-source competitors. Include enterprise customer adoption data, competitor compliance positioning, and forward-looking regulatory triggers."

Step 4: Pick effort tier

Default by user signal:

• "quick clarification" → low
• (no signal, default for follow-ups) → medium
• "thorough deep-dive" → high (use /ultra-research's polling pattern)

If the follow-up is asking for an artifact (deck, spreadsheet, app), pass --output-type=... instead of just --effort=. The sugar pins effort=build automatically.

Step 5: Submit + poll

continue POSTs to /research/{id_or_slug}/continue with {question, effort?, context?} and returns immediately with {job_id, slug, status: "queued"} — it does NOT poll. Treat it as a non-blocking submit, capture the new slug, then call result <slug> (which polls until complete) under Monitor.

The submit command differs by effort tier; the polling step is the same shape for all of them. Pick the matching block:

Low / medium effort (synchronous via Monitor):

SUBMIT=$(node "$SCRIPTS_DIR/grep-api.js" continue "$PARENT" "<refined follow-up>" \
  --effort=<low|medium>)
NEW_SLUG=$(echo "$SUBMIT" | node -e "let d='';process.stdin.on('data',c=>d+=c).on('end',()=>{const j=JSON.parse(d);process.stdout.write(j.slug||j.job_id||j.id||'')}")
[ -z "$NEW_SLUG" ] && { echo "Continue submit failed: $SUBMIT"; exit 1; }

# `result` polls until complete and prints the report
node "$SCRIPTS_DIR/grep-api.js" result "$NEW_SLUG" 2>&1

Run the result call with Monitor (timeout_ms: 560000, persistent: false). The 20s slack lets Node flush the report.

Build effort / artifact follow-up (synchronous, longer):

SUBMIT=$(node "$SCRIPTS_DIR/grep-api.js" continue "$PARENT" "Build me a slidedeck from these findings" \
  --output-type=slidedeck)
NEW_SLUG=$(echo "$SUBMIT" | node -e "let d='';process.stdin.on('data',c=>d+=c).on('end',()=>{const j=JSON.parse(d);process.stdout.write(j.slug||j.job_id||j.id||'')}")
[ -z "$NEW_SLUG" ] && { echo "Continue submit failed: $SUBMIT"; exit 1; }

node "$SCRIPTS_DIR/grep-api.js" result "$NEW_SLUG" 2>&1

Run the result call with Monitor (timeout_ms: 1800000, persistent: false). Build jobs take 10-15 min.

High effort (async — cannot block-wait):

effort=high runs up to 1 hour, exceeding the bash 10-min cap and any reasonable Monitor budget. Submit non-blocking, then schedule a /loop cron that polls every 5 min:

SUBMIT=$(node "$SCRIPTS_DIR/grep-api.js" continue "$PARENT" "<refined follow-up>" --effort=high)
NEW_SLUG=$(echo "$SUBMIT" | node -e "let d='';process.stdin.on('data',c=>d+=c).on('end',()=>{const j=JSON.parse(d);process.stdout.write(j.slug||j.job_id||j.id||'')}")
[ -z "$NEW_SLUG" ] && { echo "Continue submit failed: $SUBMIT"; exit 1; }

Then schedule the same /loop cron that /ultra-research uses (5-min interval, polls result <NEW_SLUG>, presents on completion, calls CronDelete to stop).

Effort	Polling pattern	Monitor timeout_ms
low	submit + result <slug> (synchronous)	560000 (~9 min)
medium	submit + result <slug> (synchronous)	560000 (~9 min)
build (with --output-type=)	submit + result <slug> (synchronous)	1800000 (30 min)
high	submit + /loop cron (async, like /ultra-research)	n/a

Step 6: Tell the user

"Follow-up job <new-slug> started, building on <parent-slug>. ~5 min."

Step 7: Present results

When the Monitor notification fires:

1. Lead with the chain: "I built on the prior research:"

2. Present the new report cleanly

3. Link both jobs at the bottom (use $GREP_UI_BASE, auto-derived from $GREP_API_BASE, so preview / staging links render correctly):

   Trace:

   • Prior research: ${GREP_UI_BASE:-https://grep.ai}/research/<parent-slug>
   • This continuation: ${GREP_UI_BASE:-https://grep.ai}/research/<new-slug>

This makes the lineage obvious for future follow-ups.

Step 8: Suggest further follow-ups

If the user might want to keep going, suggest:

• "Want a different angle?" → /grep-continue <new-slug> "<another follow-up>"
• "Want to materialise this as a deck/app/spreadsheet?" → /grep-continue <new-slug> "Build a <X>" --output-type=<X>
• "Want a fresh investigation on the side topic?" → /research (no continue — start clean)

Don't continue indefinitely. After 3-4 levels of nesting, the user usually wants either a fresh investigation or a build artifact — suggest those instead.

Anti-patterns

• Don't use this skill for unrelated questions. If the new question doesn't genuinely build on the parent's research, start a fresh job. Continue costs the same as a fresh job at the same effort tier — the savings are zero when the inheritance isn't useful.
• Don't continue a failed or cancelled job. The API will 422. Verify status before submitting.
• Don't pass --reference-jobs= alongside continue — continue already sets the parent reference internally. Adding extra reference_jobs is allowed (chains additional context) but rarely needed.
• Don't chain more than 3-4 continues without a clear reason. Each level adds context the model has to reconcile; eventually the inheritance gets noisy and a fresh investigation produces sharper results.
• Don't continue from someone else's job slug. The continue endpoint requires auth scope on the parent — only the original submitter (or their team, on v2) can continue.
• Don't strip slug suffixes by accident — slugs can contain hyphens and numbers (anthropic-revenue-strategy-2026). Only strip URL prefixes and query strings; never split on -.

If the parent isn't yours

If the user wants to "continue" research they didn't submit (e.g. a public Grep example URL someone shared), the API will 403 / 404. Tell the user:

"I can only continue jobs you submitted yourself. If you want to investigate this topic, I can start a fresh /research job and reference the public report's findings as context."

Then offer to run /research with the public URL pasted into --context-file= so the new job has the same starting point — without trying to use the unauthorized continue endpoint.

If the new job times out

Same pattern as /research: exit 2 + slug returned. Use result <slug> later, or switch to /loop polling for very long continuations.
