What is output-meta-post-flight?

A checklist for verifying completed Output SDK workflow work. Output SDK is a software toolkit for building workflows with defined steps, external operations, and evaluation components.

Use it after implementing a workflow to verify step completion, TypeScript imports, HTTP usage, workflow structure, error handling, retry settings, and schema placement.

It catches unfinished steps, broken project conventions, missing exports, incorrect imports, and deliverables that were not properly checked.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.01011
Opus 5	$0.00016	$0.00505
Sonnet 5	$0.00006	$0.00202
Haiku 4.5	$0.00003	$0.00101

Security

Grade A, and why

output-meta-post-flight 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 11d 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.

Post-Flight Rules for Output SDK Workflows

Execution Verification

After completing all steps in the process_flow, systematically verify:

Step Completion Audit

Every numbered step has been read, executed, and delivered according to its instructions
All steps that specified a subagent were delegated to the correct subagent
If any subagent was not used as specified, document why and report to the user
If any step was not executed according to instructions, explain which part was misread or skipped

Output SDK Convention Compliance

Verify the following conventions were followed:

Import Conventions

All TypeScript/JavaScript imports use .js extension for ES modules
No direct axios usage - HttpClient wrapper used throughout
Proper import paths for Output SDK packages (@outputai/core, @outputai/llm, etc.)

Workflow Structure

Workflow exported in entrypoint.ts: export * from './path/to/workflow.js';
All external operations wrapped in Temporal activities (steps)
Proper error handling with ApplicationFailure patterns
Retry policies configured appropriately

Schema Placement

All schemas for aiSdk.Output.object() defined in types.ts, not inline in step functions
LLM output schemas use .describe() only -- no .min()/.max()/.length() on numbers or arrays
Prompt files do not contain JSON output format instructions when aiSdk.Output.object() is used

LLM Provider & Variables

All prompt files use the same provider (no mixing unless explicitly requested)
Structured generateText/Agent variables use Liquid loops, conditions, or dot notation appropriately

Code Style (see `output-dev-code-style`)

No trailing commas in any generated code
No let declarations -- all variables use const
Arrow functions use parens only when needed (multi-param or destructured)
Operator linebreaks placed after the operator, not before
Space in parens: fn( x ) not fn(x)

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.

output-meta-post-flight is a skill published in the GitHub repository growthxai/output (435 stars, last pushed today), licensed Apache-2.0. It adds 32 tokens to every session and 1,011 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
