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 | $0.00094 | $0.00837 |
| Opus 5 | $0.00047 | $0.00418 |
| Sonnet 5 | $0.00019 | $0.00167 |
| Haiku 4.5 | $0.00009 | $0.00084 |
Grade A, and why
study-planner 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.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Study Planner
Turns a target exam + date into a week-by-week plan, then keeps it honest
against the progress log. Paths are relative to ${CLAUDE_PLUGIN_ROOT} (if
unset, resolve relative to the plugin root — the english-exam-coach
directory two levels above this file). The plan lives in the user's progress
directory ($EXAM_COACH_HOME or ~/english-exam-coach/plan.md), NOT in the
plugin.
When to use
The user names a target exam and a date (or a preparation window), asks for a study schedule, or asks "am I on track?".
Steps
-
Gather inputs: target exam id, exam date, hours/week available, current level. For current level, prefer evidence: recent CEFR estimates from the progress log (ask
progress-trackeror read<base>/attempts.jsonl); if the log is empty, run theexam-routerlevel diagnostic first. Loaddata/exam-formats/<exam-id>.mdfor the sections to cover. -
Build the plan working back from the exam date:
- First check the window is real: if the exam date is in the past, today, or leaves under ~1 week, say so plainly and offer a compressed triage plan (a timed mock section plus review of the weakest skills, no new material) instead of a normal week-by-week schedule.
- Every section of the exam appears every week; the weakest two skills (from log evidence) get double weight.
- Each week = concrete, loggable drills ("2× key-word-transformation set", "1 timed Task 2 essay with evaluation"), not vague goals ("improve grammar").
- Include one weekly review of the vocabulary box, and one full timed
mock section (
/mock-exam) every 2–3 weeks, the last one ≤1 week before the exam. - Final week: lighter load, timing practice, no new material.
-
Write the plan to
<base>/plan.mdwith YAML frontmatter (type: study-plan,exam,exam_date,hours_per_week,created). Overwriting an old plan is allowed — confirm first, and summarize what changed.
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.

study-planner is a skill published in the GitHub repository OleksiiDotsenko/english-exam-coach (8 stars, last pushed 1mo ago), licensed MIT. It adds 94 tokens to every session and 837 once invoked, about $0.0005 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 2026-08-31.

A Claude Code skill that stores and analyses spoken-English practice completed in the Claude app. The app handles the conversation; this skill keeps reports, scores, mistakes, progress trends, and the next practice focus.
language-coach
Language coaching for every prompt. Use when the user runs /language-coach with any sub-command (setup, native, target, style, response, goal, mode, focus, band, level, status, off, on). Routes to the correct action based on the argument provided.
language-review
Analyze language learning progress from local data. Use when the user runs /language-coach:language-review or asks to review their progress, see their band history, check improvement trends, or analyze their IELTS score data.
learning-and-development
Builds capability — skills gaps, career frameworks, training that transfers to the job, and internal mobility. Use this to design a career ladder, close a capability gap, decide whether to build or hire a skill, structure onboarding into a role, or work out why training keeps failing to change anything.
diagnose
A short question-based assessment of a pilot's current skill level. It produces a profile and saves it in the connected browser or database.
lesson-close
A workflow for finishing the day's lesson file, recording its status and duration, then saving it to the personal-guide GitHub repository.
