  • SKILL.md covers Overview, Prerequisites, Instructions and Authentication, plus 6 more sections
  • Needs RUNWAYML_API_SECRET

What it does

Runway Security Basics is an agent skill from jeremylongshore/tons-of-skills-marketplace. Harden Runway keys, organization access, prompts, media, generated outputs, and support evidence. Use when threat-modeling an integration. Trigger with: "secure Runway API", "Runway key rotation", "Runway media privacy".

Its SKILL.md is about 1.3k 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: Requires server-side Runway Dev access, current first-party documentation, an approved credit budget, and controlled media storage.

It sits in Security, covering Threat modeling. It works with Runway. 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

  • Threat-modeling an integration
  • With: secure Runway API
  • Runway key rotation
  • Runway media privacy

Example prompts

  • “secure Runway API”
  • “Runway key rotation”
  • “Runway media privacy”
  • “/runway-security-basics”

Requirements

  • A credential in RUNWAYML_API_SECRET
  • Compatibility (from SKILL.md): Requires server-side Runway Dev access, current first-party documentation, an approved credit budget, and controlled media storage.
  • Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Inventory identities and keys
  2. Enforce server-only access
  3. Govern input content
  4. Handle moderation honestly
  5. Control media capabilities
  6. Prove rotation and response

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
    • Grep
    • 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.dev.runwayml.com

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • RUNWAYML_API_SECRET

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

  • Compatibility

    Requires server-side Runway Dev access, current first-party documentation, an approved credit budget, and controlled media storage.

    From compatibility in the SKILL.md frontmatter.

Context cost

Runway Security Basics loads about 1.3k tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 542 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.3k

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.

Runway Credential, Media, and Moderation Controls

Overview

Runway integrations handle organization-scoped credentials and potentially sensitive media. Security must cover key lifecycle, server-only egress, input rights, temporary URL capabilities, moderation outcomes, output access, evidence minimization, and incident response.

Prerequisites

  • Data classification and media-rights policy
  • Runway organization role and key inventory
  • Secret manager, private object storage, audit logging, and incident owners

Instructions

Step 1: Inventory identities and keys

List organization members, roles, keys, consumers, environments, creation dates, and rotation owners. Removing a member does not disable their organization-scoped keys, so revocation is a separate control.

Step 2: Enforce server-only access

Keep RUNWAYML_API_SECRET in a secret manager and restrict egress to Runway hosts. Prevent browser exposure, repository commits, shell history, build arguments, logs, traces, and support archives.

Step 3: Govern input content

Verify rights, tenant authorization, data minimization, acceptable-use policy, file type and size, and public-URL exposure. Treat prompts and source media as sensitive application data.

Step 4: Handle moderation honestly

Expect moderation as a failed task and inspect failureCode. Do not automatically retry safety failures or expose unsafe diagnostics; repeated moderated requests can threaten account availability.

Step 5: Control media capabilities

Treat public input URLs, runway:// URIs, and signed output URLs as temporary access capabilities. Copy approved output to owned private storage, scan and validate it, and issue internal authorized links.

Step 6: Prove rotation and response

Rotate keys through a canary, explicitly disable old credentials, scan for leaks, and maintain a playbook for revocation, artifact restriction, customer notification, and evidence deletion.

Authentication

Bearer secrets authenticate the organization, not an end user. Authorization in the product must therefore occur before the server uses Runway; API authentication does not replace tenant, actor, media-rights, or budget checks.

Tool Discipline

Use Read and Grep to inspect application configuration, provider documentation, lockfiles, fixtures, schemas, tests, and redacted operational evidence before proposing a change. Use Write or Edit only for an approved implementation, configuration, test, runbook, or redacted receipt. Do not create, cancel, delete, retry, deploy, rotate, revoke, publish, or otherwise mutate production Runway resources without explicit operator approval.

Output

  • Key, role, consumer, and data-flow inventory
  • Threat model and prioritized credential/media/moderation controls
  • Rotation test and incident-response evidence

Return the environment, organization alias, operation and task identifiers, API and SDK versions, model or router policy, source-contract fingerprint, task-state evidence, credit boundary, output disposition, unresolved risk, rollback state, and final decision without exposing API secrets, prompt or media contents, or temporary signed URLs.

Examples

A developer leaves the organization. The admin removes membership, separately identifies and disables every key used by that service, deploys a replacement secret, proves one read-only canary, and scans logs and artifacts for the old prefix.

Error Handling

FailureResponse
Secret scanner finds a Runway keyRevoke it immediately, restrict the artifact, determine exposure, rotate consumers, and document the incident.
Customer media is on a public URLStop submission until access and rights meet policy; use a controlled upload path where appropriate.
Safety failure is retried automaticallyDisable that retry class and review prompt, media, and moderation policy.

Validation

Test client-side bundle inspection, secret scanning, least-privilege deployment access, old-key failure after rotation, media authorization, output URL redaction, safety-failure handling, and evidence expiry.
