What it does

Lucidchart Install Auth is an agent skill from jeremylongshore/tons-of-skills-marketplace. Choose and configure the correct Lucid authentication model: API key, OAuth user token, or OAuth account token. Use when bootstrapping or repairing Lucid REST access. Trigger with "configure Lucid auth".

Its SKILL.md is about 980 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; credential creation, OAuth registration, consent, and account-token grants require administrator or resource-owner approval

It sits in Backend & APIs, covering OAuth and OpenID Connect and Authentication. 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

  • Repairing Lucid REST access
  • With configure Lucid auth

Example prompts

  • “configure Lucid auth”
  • “/lucidchart-install-auth”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code; credential creation, OAuth registration, consent, and account-token grants require administrator or resource-owner approval
  • 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. Re-fetch authentication methods, the exact operation, access scopes, and headers.
  2. Create an auth decision record: credential class, principal, resources, scopes, expiration, rotation, and revocation.
  3. Inspect the project for hard-coded tokens, unsafe redirects, committed environment files, and mixed credential classes.
  4. Define environment-variable names and a secret-provider interface without writing values.
  5. For OAuth, validate exact redirect URIs, state handling, authorization-code exchange, secure token storage, refresh behavior, and…
  6. Present any app registration, consent, account grant, or secret creation for explicit approval.
  7. After credentials are provisioned outside the transcript, perform the smallest documented read-only verification and capture only status…

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

    No URLs in SKILL.md.

    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; credential creation, OAuth registration, consent, and account-token grants require administrator or resource-owner approval

    From compatibility in the SKILL.md frontmatter.

Context cost

Lucidchart Install Auth loads about 979 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 387 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~979
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.2k

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.

Lucid Installation and Authentication

Overview

Select the least-privilege credential class for the operation, configure a secretless local contract, and verify identity and scope without exposing credentials.

Prerequisites

  • The exact Lucid operation, resource owner, environment, and required scopes
  • A registered OAuth application when user or account OAuth is selected
  • An approved secret store and rotation owner

Tool Discipline

Use Read, Glob, and Grep to inspect configuration templates, WebFetch for current auth and scope contracts, and Write or Edit only for secretless examples or redacted receipts.

Current Contract

Lucid documents API keys, OAuth user tokens, and OAuth account tokens. OAuth applications use Authorization Code Flow. REST credentials are normally sent as Authorization: Bearer ...; an operation may also require a resource-specific Lucid-Api-Version header.

Authentication

  • Use an API key only where the current operation supports it and personal ownership is acceptable.
  • Use OAuth user tokens for delegated user access and consented scopes.
  • Use OAuth account tokens only for documented account-level use with administrator authorization.
  • Never substitute a fabricated Lucid-Api-Key header or log authorization values.

Instructions

  1. Re-fetch authentication methods, the exact operation, access scopes, and headers.
  2. Create an auth decision record: credential class, principal, resources, scopes, expiration, rotation, and revocation.
  3. Inspect the project for hard-coded tokens, unsafe redirects, committed environment files, and mixed credential classes.
  4. Define environment-variable names and a secret-provider interface without writing values.
  5. For OAuth, validate exact redirect URIs, state handling, authorization-code exchange, secure token storage, refresh behavior, and revocation.
  6. Present any app registration, consent, account grant, or secret creation for explicit approval.
  7. After credentials are provisioned outside the transcript, perform the smallest documented read-only verification and capture only status, principal class, scopes, and safe request identifiers.

Approval Boundaries

Do not create keys, register or modify OAuth apps, authorize accounts, broaden scopes, or rotate/revoke credentials without the relevant owner.

Output

Return auth decision, required scopes and headers, secretless configuration, verification receipt, rotation/revocation owner, and unresolved access gaps.

Error Handling

ConditionResponse
Operation rejects a credential classRe-check the operation-specific auth table; do not try random headers.
OAuth redirect or state validation failsStop the exchange and repair the application configuration.
Scope is insufficientRequest the narrow documented scope; never silently broaden consent.

Example

text
mode=oauth-user; principal=user-delegated; scopes=verified-current-docs; token-output=redacted; smoke=pass

Resources

Next Steps

Test revocation and rotation in a non-production environment before depending on the credential operationally.
