What is ai-oral-coach-skill?

A guided tool for building an AI English-speaking coach with Tencent Cloud TRTC Conversational AI, a service for real-time voice communication.

Use it to create English-speaking practice with scenarios, sentence corrections, reply suggestions, and a four-part progress report, or to connect an existing backend.

It lets users practice without working directly in a terminal and provides either a ready-made practice app or an integration path for an existing system.

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	$0.00082	$0.08003
Opus 5	$0.00041	$0.04001
Sonnet 5	$0.00016	$0.01601
Haiku 4.5	$0.00008	$0.00800

Security

Grade C, and why

ai-oral-coach-skill scanned grade C with 3 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 7d ago.

The scan reads SKILL.md. This mod also ships 39 executable files (capabilities/ability-report/src/__init__.py, capabilities/ability-report/src/adapters/__init__.py, capabilities/ability-report/src/adapters/default.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 380 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AI Oral Coach Skill

This file is the Coding Agent's execution SOP. Any intent involving "build / integrate AI oral coach" — read this file first. All script calls must follow §8 Tool Whitelist and use $SKILL_ROOT absolute paths.

0. Path Baseline (Read First)

Variable	Meaning	Source
`SKILL_ROOT`	This Skill's directory (contains `SKILL.md` / `capabilities/` / `scripts/`)	Absolute path of the Base directory injected by the system when loaded
`PROJECT_ROOT`	User's current workspace root (Path A artifacts land here / Path B integration target)	Current workspace root

Hard rules: ① All script/asset commands use $SKILL_ROOT absolute paths — bare relative paths forbidden. ② Substitute $SKILL_ROOT / $PROJECT_ROOT in templates with real absolute paths before execution. ③ If SKILL_ROOT cannot be found, fallback: find "$PWD" -maxdepth 4 -name SKILL.md -path '*oral-coach*' — never ask the user to move directories.

1. When to Use

Triggers hit when the user message matches §triggers keywords, or contains "TRTC + oral coach / English speaking practice". Not applicable: Customer service / after-sales → use ai-customer-service Skill; non-TRTC ecosystems (Agora etc.) → route to corresponding Skill. Product positioning: voice-first. Text-only requests → advise the user to configure themselves. This Skill does not produce text-only artifacts.

2. Interaction Language & Copy Style

Determine interaction_lang from the message that triggered this Skill (Chinese → zh / otherwise → en). All guidance, questions, and error messages throughout use interaction_lang; switch immediately if the user requests it mid-session. Do not fix the interaction language based on what language this file is written in. Path A UI defaults to following interaction_lang (practice conversations fixed in English); Path B has no UI — only dialogue / comments / docs language.

Copy style (hard rules): All user-facing guidance must be beginner-friendly —

Use plain language, no jargon; when terms like UserSig / OpenAPI / adapter appear, explain in one sentence what they do;
Each step says "what we're doing now, what you need to do (usually wait), roughly how long";
On failure, give "symptom + what to do", never dump raw stack traces;
Only ask the user to do one thing at a time.

Changes

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.
