What it does

Attio Reference Architecture is an agent skill from jeremylongshore/tons-of-skills-marketplace. Design a production Attio integration architecture with tenant-bound credentials, schema discovery, queued writes, verified webhooks, idempotency, reconciliation, and rollback ownership. Use when planning or reviewing a multi-workspace Attio service. Trigger with "Attio architecture", "design Attio integration", or "Attio system design".

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering Webhooks and Accounting and bookkeeping. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Reviewing a multi-workspace Attio service
  • With Attio architecture
  • Design Attio integration
  • Attio system design

Example prompts

  • “Attio architecture”
  • “design Attio integration”
  • “Attio system design”
  • “/attio-reference-architecture”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Map ingress, egress, data stores, trust boundaries, tenant context, and failure domains from the repository.
  2. Define a credential resolver and auditable endpoint-to-scope map.
  3. Add a bounded schema registry or cache with explicit refresh and invalidation.
  4. Route outbound mutations through idempotent jobs with separate read and write governors.
  5. Terminate webhooks at an HTTPS receiver that verifies the raw body, deduplicates by idempotency key, acknowledges quickly, and queues work.
  6. Add replay, dead-letter handling, periodic reconciliation, and operator-visible lag metrics.
  7. Specify deployment order, canary cohort, rollback, recovery exercise, and component owners.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • WebFetch
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.attio.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Attio Reference Architecture loads about 1k tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 381 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Attio Integration Reference Architecture

Overview

This skill produces a repo-grounded architecture for reliable Attio reads, writes, and events. It treats tenant isolation, duplicate delivery, schema evolution, and reconciliation as first-class controls.

Prerequisites

  • Workspace and tenancy model
  • Required objects, lists, attributes, records, entries, and events
  • Availability, freshness, recovery, and retention objectives
  • Owners for credentials, queues, data mapping, and incident response

Tool Discipline

Use Read, Glob, and Grep to map components, trust boundaries, state, and existing clients. Use WebFetch only for current official Attio contracts. Use Write or Edit after the architecture, ownership, and approval boundaries are agreed.

Current Contract

  • Use OAuth for multi-workspace applications and a workspace key only for a controlled single-workspace integration.
  • Discover object and attribute identifiers rather than hard-coding display labels.
  • Pagination differs by endpoint, and record or entry queries can carry score-based rate cost.
  • Webhooks are at-least-once signals; durable processing needs signature verification, idempotency, a queue, and reconciliation.

Authentication

Place a tenant credential resolver behind a server-side interface. Bind each encrypted token to one workspace identity and exact scopes; never accept a workspace identifier from a caller without authorization.

Instructions

  1. Map ingress, egress, data stores, trust boundaries, tenant context, and failure domains from the repository.
  2. Define a credential resolver and auditable endpoint-to-scope map.
  3. Add a bounded schema registry or cache with explicit refresh and invalidation.
  4. Route outbound mutations through idempotent jobs with separate read and write governors.
  5. Terminate webhooks at an HTTPS receiver that verifies the raw body, deduplicates by idempotency key, acknowledges quickly, and queues work.
  6. Add replay, dead-letter handling, periodic reconciliation, and operator-visible lag metrics.
  7. Specify deployment order, canary cohort, rollback, recovery exercise, and component owners.

Approval Boundaries

Do not broaden data collection, scopes, retention, tenant access, or mutation authority without approval from the relevant data and service owners.

Output

Return a component-and-data-flow design, trust boundaries, endpoint contracts, failure controls, ownership matrix, rollout sequence, and rollback plan.

Error Handling

ConditionResponse
Tenant cannot be resolved safelyReject the operation before credential lookup.
Schema cache is staleRefresh discovery and pause incompatible writes.
Webhook queue is unavailableFail closed so Attio can retry; preserve observability.
Reconciliation finds driftQuarantine conflicting mutations and assign an owner.

Examples

Input:

text
tenancy=multi-workspace; flows=record sync and webhooks; recovery=required

Expected handoff:

text
auth=oauth resolver; writes=queued; webhooks=verified; reconciliation=scheduled
