Install

Skills CLI

npx skills add synthesisengineering/synthesis-skills

Asks which skills and agents to install. Just one: npx skills add synthesisengineering/synthesis-skills --skill synthesis-absence-coordination — add -g for every project.

Claude Code

git clone https://github.com/synthesisengineering/synthesis-skillscp -r "synthesis-skills/skills/synthesis-absence-coordination" ~/.claude/skills/

Copies the synthesis-absence-coordination skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add synthesisengineering/synthesis-skills

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md — showing the first 30 of 70 files.

  • synthesis-absence-coordination

    Coordinate an absence end to end (vacation, conference, family visit, medical leave): notification order, coverage and reachability, meeting release, personal-continuity notes, out-of-office set and clear, return sweep. Use when planning time off, announcing an absence or arranging coverage.

    skills/synthesis-absence-coordination/SKILL.md on GitHub (opens in a new tab)
  • synthesis-action-sheet

    One page of what the principal must still do after agents act: done items folded, staged sends awaiting approval codes, their own messages and tasks with exact text, Copy, open-in-app links, marks, Me or Agent, and a paste-back. Use after a decision packet or daily plan.

    skills/synthesis-action-sheet/SKILL.md on GitHub (opens in a new tab)
  • synthesis-adversarial-review

    Run bounded adversarial review by differently shaped agents against the principal's outcome: artifact-complete rounds, production-topology handoffs, concessions, a markdown findings table, sufficiency rulings, post-publication acceptance. Use for adversarial, cross-agent or red-team review.

    skills/synthesis-adversarial-review/SKILL.md on GitHub (opens in a new tab)
  • synthesis-agent-conformance

    Audit and verify that synthesis behaves the same in Claude Code, Codex and Muse: source lint, installed parity, hook wiring and trust, AGENTS.md/CLAUDE.md adapters, skill catalogs, and project handoff between harnesses. Use for parity audits, instruction migrations, or checks after install.

    skills/synthesis-agent-conformance/SKILL.md on GitHub (opens in a new tab)
  • synthesis-agent-correspondence

    Compose and send honest agent correspondence on Slack, email and other channels: principal-direct, assistant and bot lanes, the voice axis, review depth, personas, disclosure signatures and send gates. Use for sending on a principal's behalf, message signatures, persona registries or agent voice.

    skills/synthesis-agent-correspondence/SKILL.md on GitHub (opens in a new tab)
  • synthesis-agent-guardrails

    Pre-tool guards beyond sends: the account a calendar or mail call acts as, a browser call's Chrome profile, deploys and their date rules, destructive commands; the reply check and day-end provenance scan. Use to configure them, or when a deploy, delete, calendar or browser call is blocked.

    skills/synthesis-agent-guardrails/SKILL.md on GitHub (opens in a new tab)
  • synthesis-anti-shortcuts

    Catch the lazy-shortcut antipattern: costume vocabulary that hides deferral, dismissal or false consultation. Constraint-first protocol, sub-agent dispatch and acceptance hygiene, pre-response self-check. Use to avoid shortcuts, audit for laziness, check for deferral or enforce the best solution.

    skills/synthesis-anti-shortcuts/SKILL.md on GitHub (opens in a new tab)
  • synthesis-article-refresh

    Refresh an older published article into its best version: clearer argument, fuller period-appropriate evidence, better structure and alt text, keeping the author's voice and absolute temporal integrity. Use to refresh, revitalize, update or polish an older post.

    skills/synthesis-article-refresh/SKILL.md on GitHub (opens in a new tab)
  • synthesis-article-writing

    Write and review thought leadership articles and blog posts: reader briefing, research, drafting, critical review, and publication-package review (title-only stranger test, title/description/body truth contract, batch headline budgets, slug closure). Use for headline or publication-readiness review.

    skills/synthesis-article-writing/SKILL.md on GitHub (opens in a new tab)
  • synthesis-autopilot

    Run an explicitly delegated whole task to the end from a plan file in the project, unattended when needed. Use only on clear end-to-end delegation ('autopilot this', 'handle this end to end', 'run overnight'), never on a single-step approval or a talk about autonomy.

    skills/synthesis-autopilot/SKILL.md on GitHub (opens in a new tab)
  • synthesis-bitbucket

    Work with Bitbucket Cloud via the open-source bkt CLI: PR lifecycle, repo and branch reads, and the bkt api escape hatch, with explicit repository binding and write-safety rules. Use when asked to: bitbucket, bkt, bitbucket pr, open bitbucket pr, review bitbucket pr, bitbucket cli, bitbucket api.

    skills/synthesis-bitbucket/SKILL.md on GitHub (opens in a new tab)
  • synthesis-catchup-ledger

    Reconcile missed and pending commitments after a break in the daily-ritual cadence: sweep plans, transcripts and context over any window, classify every item into a dated catch-up ledger, and route survivors without flooding the plan. Use for post-vacation catch-up or what did I miss.

    skills/synthesis-catchup-ledger/SKILL.md on GitHub (opens in a new tab)
  • synthesis-checkpoint

    Re-sync a session with ground truth: verified clock, project records, git, dated session entries and board claims. Use for checkpoints, drift or compaction recovery, 'where are we?', resuming after a pause, and refresh-and-report after an ecosystem upgrade.

    skills/synthesis-checkpoint/SKILL.md on GitHub (opens in a new tab)
  • synthesis-chief-of-staff

    Act as a principal's chief of staff and executive assistant: meeting triage, calendar scheduling and defense, look-ahead reviews, overcommitment checks, tracked holds, travel, correspondence and a follow-up ledger, per private preferences.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
