Friday

A Claude Cowork plugin. Reads your Gmail, Calendar, and Fireflies transcripts every morning and maintains a personal CRM for you in a Google Sheet. You bring the deals — Friday tends them.

What it does

Two jobs.

Opportunity identification. Each daily sweep, Friday asks: who am I in conversation with that isn't yet in my pipeline? When it finds someone — a question you asked that never got answered, a meeting you held but never followed up on, a thread that went silent after you sent a pricing nudge — it drops them in a Triage tab for you to graduate into MEET or NURTURE, dismiss, or snooze.

Follow-up reminders. Friday watches every row already in your Sheet. If Next Action Date lapses, the row surfaces. If you committed to sending something three weeks ago and haven't, the row surfaces. If a NURTURE contact has gone untouched for a month, the row surfaces. Each morning you open Claude Desktop and see exactly what needs attention today.

And one more — the Friday ritual. Every Friday morning a separate scheduled task fires follow-up-friday: a focused, five-deal nudge list of the warm deals that have gone quietly cold (no touches in > 30 days), ranked by MEDDPICC score so the most rescuable ones rise to the top. Each pick comes with a suggested reconnect draft.

How it works

Friday is a Claude Cowork plugin — twelve composable skills plus reference docs. State lives entirely in your Google Sheet (the scheduled-task session is fresh each run; nothing relies on in-session memory). Native first-party connectors only — Gmail, Google Calendar, Fireflies, Google Drive — authorized once at the Claude account level. No backend, no accounts, no shared infrastructure.

Install

This repo is structured as both a Claude plugin marketplace and the plugin itself. Pick the install path that matches where you're using it.

Claude Cowork (Claude Desktop)

1. In Claude Desktop, open the Cowork tab.

2. Click Customize in the left sidebar.

3. Under Personal plugins, click the + button → hover Create plugin > → click Add marketplace.

4. In the dialog, paste:

   https://github.com/Collin128/friday-plugin
   

   (Or use the short form: Collin128/friday-plugin.)

5. Click Sync. Cowork registers the marketplace as collin128-friday.

6. Find the friday plugin under Personal plugins and install it.

That's it for the plugin install. See After install below.

Claude Code (CLI)

/plugin marketplace add Collin128/friday-plugin
/plugin install friday@collin128-friday
/reload-plugins

Local development (edit SKILL.md files in place)

Clone, then add the marketplace by local path:

git clone https://github.com/Collin128/friday-plugin.git ~/web/friday-plugin

In Claude Code:

/plugin marketplace add ~/web/friday-plugin
/plugin install friday@collin128-friday

Edits to plugins/friday/skills/<name>/SKILL.md show up after /reload-plugins.

After install

1. Authorize the connectors. In Claude Desktop, open Customize → Connectors and authorize Gmail, Google Calendar, Fireflies, and Google Drive. Drive needs WRITE access — Friday writes to your CRM Sheet.

2. Run the setup ritual. In a Cowork chat, type the natural-language phrase (not a slash command):

   set up Friday

   ⚠️ Don't use /friday-setup as a slash command. Cowork's slash-invocation path is unreliable for plugin skills — it may stall silently or error with "No conversation found with session ID." Cowork triggers skills off the natural-language description: field, so saying the phrase plainly is the reliable path. Other triggers that work: "install Friday", "get Friday going".

   Friday will open the SHARED CRM template (or walk you through creating a Sheet from scratch), capture the new Sheet URL, run a 52-week backfill, and print two /schedule strings.

3. Paste the /schedule strings. In Cowork's /schedule UI, paste each — one for the daily morning briefing, one for the weekly Friday ritual.

4. Open Claude Desktop tomorrow morning. Your first daily briefing lands on the Scheduled tasks page at the time you set.

Troubleshooting install

• "Marketplace sync failed" when adding the marketplace → confirm the URL is the public repo (https://github.com/Collin128/friday-plugin or Collin128/friday-plugin), not a deep link to a file. Cowork fetches .claude-plugin/marketplace.json from the repo root.
• Cowork doesn't show a + next to Personal plugins → make sure you're on a recent Claude Desktop build; the plugins UI rolled out alongside Cowork.
• "Unknown skill: plugin" if you typed /plugin marketplace add ... into Cowork's chat box → that's a Claude Code CLI command, not a Cowork chat command. Use the Customize panel flow above instead.
• "Something went wrong / No conversation found with session ID" after typing /friday-setup (or any slash form of a Friday skill) → Cowork's slash-invocation path for plugin skills is flaky. Type the natural-language phrase instead: set up Friday, run friday-sweep using sheet <URL>, review Friday, etc. The skills are written so Cowork's description matcher picks them up off the natural phrase.

The Sheet

Friday operates on a six-tab Google Sheet:

• MEET / DISCO / MANAGE / NURTURE — your four pipelines. You own Company, Name, and Notes. Friday writes Next Action, Next Action Date, Opp Stage, the eight MEDDPICC dimensions, and SCORE.
• Triage — Friday-managed queue of new candidates for you to graduate, dismiss, or snooze.
• Activity Log — append-only audit trail. Every change Friday writes (or suggests) has one row here with evidence_link back to the email, calendar event, or transcript that justified it.

Schema details and write discipline live in skills/friday-sheet/SKILL.md.

Skills

Skill	Role
friday-setup	One-time install ritual — Sheet copy, /schedule strings.
friday-backfill	Sequential 52-week walk through Gmail / Calendar / Fireflies.
friday-sweep	Daily reactive sweep. Fires from /schedule.
follow-up-friday	Weekly Friday-morning ritual — top 5 stale-deal nudges.
friday-review	Interactive walk-through; the only place pending changes get applied.
friday-funnels	Four pipelines + stage taxonomies + transition rules.
friday-meddpicc	0/1/2 scoring rubric per dimension.
friday-heuristics	Opportunity-ID rules h1–h6 + meeting-held-no-follow + noise filters.

friday-commitments	iWill / theyWill / followupBy extraction from outbound + transcripts.
friday-draft	Three follow-up archetypes + the 8 writing invariants.
friday-sheet	Canonical schema + write discipline (consulted by every other skill).

Each lives in skills/<name>/SKILL.md. Reference docs in skills/<name>/references/.

Conventions

See CONVENTIONS.md for filesystem layout, SKILL.md frontmatter format, and skill body templates. See CLAUDE.md for the discipline (one PR per phase, prompt-only v1, don't bundle).

Testing — honest gaps

No automated test suite in v1. Reasons:

• Cowork's native Gmail / Calendar / Fireflies connectors don't have a usable sandbox or fixture mode that a plugin can hook into.
• Real-account testing is the only way to validate matching + heuristics end-to-end.

What is in place:

• Sub-skills with branching logic (friday-deals, friday-heuristics, friday-commitments) ship with fixture files under skills/<skill>/references/fixtures/ and a how-to-exercise.md walking you through manual tests against a sandbox Sheet.
• The plugin was dogfooded against the author's own Cowork install with a 90-day backfill + spot-check of 20 Triage rows before any public release.

If you find a behavior that drifts from the documented intent, please open an issue. v1 has no test coverage — every bug report is informative.

Future work (deferred from v1)

• Batched parallel backfill. Sequential 52-week takes 30–60 minutes. If that's consistently slow, a friday-week-scanner sub-agent in agents/ is the next lever.
• Python helper scripts for deterministic helpers (entity resolution branching, composite-score math, top-5 ranking). Cowork's local Linux VM makes these viable; v1 is prompt-only to keep one surface per skill.
• Per-deal commentary memory. Wrap the plugin in a Cowork project so memory persists across sessions; have friday-sweep build per-deal qualitative context. Requires opting into project memory.
• Mobile push. Cowork's mobile feature could let you trigger friday-review from your phone.
• Sentiment / red-flag detection. Look for "going dark" signals beyond date-based decay — tone shifts, slower replies, missed meetings.
