external-integration-adequacy

external-integration-adequacy is a skill for Claude Code, Codex from evolplus/talos. It costs 79 tokens per session (610 once invoked), scanned A, original, Apache-2.0.

A pre-approval process for checking documentation about external systems that a product must connect to. It fills in how those integrations operate, authenticate, handle failures, meet performance needs, and address regional or compliance limits.

In plain words
What is it for?
Use it to document endpoints or messages, request and response formats, authentication, retries, rate limits, webhooks, vendor errors, latency expectations, and unresolved integration issues.
Why use it?
It turns incomplete integration placeholders into information that architects and developers can assess. It also highlights systems or requirements that are not adequate or still have gaps.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

external-integration-adequacy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

External Integration Adequacy

Use

Use this skill when BA Phase 1.X created integration placeholders and the Orchestrator dispatches SA in external-integration-adequacy mode. This runs before SRS sign-off.

Inputs

  • Placeholder files under docs/external-integrations/<system-slug>.md
  • Linked US/FR files for each placeholder
  • SRS §3.5 integration index
  • solution-defaults for in-org default systems
  • Vendor/in-org interface docs named by Source-URL

Outputs

  • Updated external-integration files
  • Mirrored SRS §3.5 Adequacy values only when needed
  • Worktree plan-update.json summarizing adequate vs inadequate systems

Procedure

For each placeholder:

  1. Read header metadata, linked US/FRs, owner/source fields, and existing §7 gaps.
  2. Pre-fill from solution-defaults when available, then fill product-specific details from source docs.
  3. Fill §2 Operations, one subsection per operation:
    • endpoint/topic/RPC, protocol, direction, auth mode, idempotency;
    • request/response schemas, success and error variants;
    • vendor error code -> meaning -> product handling -> local error envelope;
    • rate limit, latency/SLO, retry policy, webhook/callback details.
  4. Fill §3 Authentication & Authorization.
  5. Fill §4 Non-Functional Posture.
  6. Fill §5 Failure Modes.
  7. Fill §6 Regional / Compliance when applicable.
  8. Record every missing source-backed field in §7 Open Adequacy Issues.
  9. Set Adequacy: adequate only when every operation is complete and §7 is empty; otherwise set inadequate.
  10. Stamp validation metadata and changelog.
  11. Mirror the SRS §3.5 Adequacy column to match the file header. Do not edit any other SRS body content.
  12. Commit, then emit plan-update.json.

Hard Rules

  • SA is the only role permitted to set Adequacy: adequate.
  • Never set Adequacy: deferred.
  • Never invent vendor/interface details.
  • Never leave TODO markers without matching §7 gaps.
  • Keep files self-contained; body sections must not say see <vendor URL>.
  • Do not discover/propose new dependencies in this mode.
  • Commit before signaling ready-to-finalize.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
