What is formax-config-settings-workflow?

A workflow for changing a project's configuration and settings system, including stored values, prompt additions, request parameters, and settings-dialog controls. It includes the files and contracts that define these behaviors.

Use it to add or extend /config settings, change how values are saved or combined, expose settings to prompts or requests, and add tests.

It helps keep configuration merging, persistence, prompts, and the user interface consistent when settings change.

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	$0.00035	$0.01058
Opus 5.5	$0.00014	$0.00423
Sonnet 5.5	$0.00007	$0.00212
Haiku 4.5	$0.00003	$0.00106

Security

Grade A, and why

formax-config-settings-workflow 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 2mo 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.

Goal

Use this skill when changing runtime config merge semantics, /config persistence, or the current settings exposed by the config dialog.

Read First

docs/contracts/config-settings-contract.md
docs/environment-variables.md
docs/contracts/prompt-tool-exposure-contract.md when a setting affects prompt injection or request composition

These docs are canonical. If stable behavior changes, update them before or with code.

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.
