Included Skills50

synthesis-absence-coordinationskills/synthesis-absence-coordination/SKILL.md

Coordinate an absence end to end — vacation, conference travel, family visits, medical leave — the way a good chief of staff would. Covers the notification order that protects relationships (principals hear it from you, never from their own assistant or a group channel), coverage and reachability as required content rather than afterthoughts, recurring-meeting release, the personal-continuity tier that keeps a trainer or therapist or tutor in the loop while you travel, travel-logistics forwarding, out-of-office set AND clear, and the return sweep. All names, tiers, channels, and lead times load from a private config, so the skill is publishable and the configuration is yours. Use when planning time off, booking work travel, announcing an absence, arranging coverage, or returning from one.

synthesis-adversarial-reviewskills/synthesis-adversarial-review/SKILL.md

synthesis-autopilotskills/synthesis-autopilot/SKILL.md

Execute an explicitly delegated whole task autonomously using the thinking framework, durable plan and context, checkpoints, anti-shortcut discipline, and implementation-integrity gate — and, for unattended runs, a verified continuation mechanism with budget and runaway control, so overnight and multi-day engagements keep producing turns instead of idling silently. Activate only for clear end-to-end delegation such as 'autopilot this,' 'take care of this for me,' 'handle this end to end,' 'run overnight,' or 'complete all phases autonomously'; never infer it from a single-step approval, discussion of autonomy, or ambiguous wording.

synthesis-bitbucketskills/synthesis-bitbucket/SKILL.md

Work with Bitbucket Cloud repos through the open-source bkt CLI — PR lifecycle (list, view, diff, comment, approve, merge), repo/branch reads, and the bkt api escape hatch.

synthesis-chief-of-staffskills/synthesis-chief-of-staff/SKILL.md

Act as a principal's chief of staff and executive assistant. Protects the principal's time through meeting triage, calendar-aware scheduling, look-ahead reviews, overcommitment checks, tracked holds, travel planning, correspondence posture, and a follow-up ledger; personal rules load from private preferences. Use for scheduling, meeting requests, calendar-related replies, calendar defense, travel, or any chief-of-staff and executive-assistant duty.

synthesis-message-guardskills/synthesis-message-guard/SKILL.md

Fail-closed pre-send enforcement for agent-drafted correspondence. A PreToolUse hook blocks every message-sending or draft-creating tool call unless the outgoing text passes a deterministic register scan AND a fresh, single-use grounding ledger — sha256-bound to the exact message — attests that the composing agent read the full thread, searched prior correspondence, and mapped every factual claim to a source. Use when setting up, debugging, or composing under the guard; when a send is blocked; or when asked about message grounding, voice enforcement, or pre-send gates.

synthesis-model-tiersskills/synthesis-model-tiers/SKILL.md

Cross-provider model-tier convention for agentic work: three role labels (judgment, routine, bulk — formerly frontier, efficient, light) resolved to current model IDs per provider in tiers.yaml, so skills, project docs, and memory never hardcode model names. Also carries the role-selection rule: route by whether the CAUSE is known, not by how small the task looks — a symptom report is diagnosis and belongs in judgment even when the subject is one file. Use when asked about: model tiers, which model, model selection, judgment model, routine model, bulk model, frontier model, efficient model, switch models, model equivalents across providers, update model table, which effort level, low effort, wrong model for the task.

synthesis-promotion-gateskills/synthesis-promotion-gate/SKILL.md

Configure and run a fail-closed publication promotion gate that builds in isolation, derives output routes from frontmatter, consumes identity-bound representations from the destination parser or renderer, binds receipts to exact inputs and renderer surfaces, and permits a state-changing promotion command only after immediate revalidation. Use for publication gates, outward-surface cleanliness, rendered-output inspection, publishable-range contracts, or promotion receipts.

synthesis-quick-answersskills/synthesis-quick-answers/SKILL.md

Stand up and operate a low-cost, read-mostly companion session for ad hoc workspace lookups without pulling a focused project session off task. Every answer carries its source and a Verified, Cached, or Uncertain confidence tier. The workspace's tracked instruction source routes future sessions to the companion automatically. Bootstraps a missing personal knowledge workspace through the public synthesis CLI. Use for an FAQ assistant, quick-answers session, lookup companion, ask-me-anything session, fast Q&A project, or one-off lookup that is not the focused project's task. Not for deep project work, decisions, drafting, sending messages, or work that belongs in its own project.

synthesis-reader-briefingskills/synthesis-reader-briefing/SKILL.md

Pre-writing reader briefing methodology for public articles. A required precondition for any article that draws on internal source material (lessons, project context, codebases) and is published to an external audience. Catches insider context collapse before it becomes a draft, and declares the article's series-dependency state (standalone, standalone after compact context, or true prerequisite). Use when asked to: write article, plan article, brief audience, audience analysis, reader briefing, pre-writing, before drafting, who is this for, series dependency, prerequisite article.
