formax: Skill for Codex

.codex/skills/formax-expanded-transcript-workflow/SKILL.md

formax-expanded-transcript-workflow is a skill for Codex from yusifeng/formax. It costs 30 tokens per session (714 once invoked), scanned A, original, MIT.

A workflow guide for changing and debugging an REPL’s expanded transcript view, including how its displayed conversation and internal reasoning are kept consistent.

In plain words
What is it for?
Use it when changing Ctrl+O expanded transcripts, compact views, thinking persistence, or related clear and remount behavior.
Why use it?
It reduces guesswork about which code and documentation control keyboard shortcuts, rendering, persistence, and resets.

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

formax-expanded-transcript-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 Ctrl+O expanded transcript behavior, thinking persistence, or compact / expanded projection boundaries in the REPL.

Read First

  • docs/contracts/transcript-surface-contract.md
  • docs/contracts/semantics-contract.md
  • docs/runbooks/repl-surface-debugging.md when the change can affect clear / remount behavior

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

If the change touches clear / remount ownership directly, also use formax-surface-reset-workflow.

Code Map

  • Key handling: packages/core/src/screens/repl/hotkeys.ts
  • View wiring + footer: packages/core/src/screens/REPL.tsx
  • Compact projection: packages/core/src/screens/repl/compactProjection.ts
  • Transcript rendering: packages/core/src/screens/repl/transcript.tsx
  • Thinking persistence: packages/core/src/features/repl/controller/streaming/streaming.ts
  • Expanded Transcript panels: packages/core/src/screens/repl/panels.tsx
  • Compact command lifecycle: packages/core/src/features/repl/controller/send/send.ts
  • Surface reset owner: packages/core/src/screens/repl/useSurfaceTransitionManager.ts

High-Signal Patterns

  • No fake thinking:
    • thinking_delta is the only source of truth
    • never synthesize thinking rows from timers or summaries
  • Avoid Static hacks for toggles:
    • Static is append-only; if content must disappear, use reset / remount ownership instead of trying to "unrender" it
  • One footer:
    • prefer a single global footer; avoid per-panel footer duplication
  • Compact ordering contract:
    • keep banner -> summary (expanded only) -> > /compact ... -> compact subline
  • UI vs LLM orthogonality:
    • transcript slicing and ui.kind remain independent from prompt-history packing and reminder injection

Minimal Workflow

  1. Lock the semantic source first: thinking_delta persistence and transcript projection rules before renderer polish.
  2. Keep default transcript low-noise and Expanded Transcript read-only.
  3. Preserve compact / expanded ordering before adjusting footer or panel layout.
  4. If clear / remount logic changes, route through the shared surface reset path instead of local Static workarounds.
  5. Run the regression set below before review.

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.
