| name | progress-tracker |
| description | Use to log a completed exam-practice attempt or to generate a progress report. Call it right after any writing/speaking/reading/listening/ vocabulary task is scored to append the result, and when the user asks to see results or trends ("show my progress", "session report", "how am I doing on writing", "what's my weakest task?"). Reads and appends to the user's progress directory ($EXAM_COACH_HOME or ~/english-exam-coach/); the log is append-only.

Progress Tracker
Two-layer model: attempts.jsonl is the append-only source of truth;
Markdown reports in reports/ are derived and regenerable. Scripts live at
${CLAUDE_PLUGIN_ROOT}/skills/progress-tracker/scripts/ (if the variable is
unset, resolve relative to this SKILL.md).
The base directory is resolved by the scripts themselves:
--base flag → $EXAM_COACH_HOME → ~/english-exam-coach/. Because
attempts are usually logged inline by another skill — which silently creates
~/english-exam-coach/ on first write — the default-vs-custom choice must be
surfaced at the first real entry point (/start-prep, or exam-router before
its diagnostic) before any attempt is logged: ask once whether the user
wants the default (~/english-exam-coach/) or a custom path such as an
Obsidian vault folder, then suggest exporting EXAM_COACH_HOME in their
shell profile to persist the choice. If this skill is nonetheless the first
to log and no base exists yet, ask that same question before the first write.
When to use
- After ANY task is scored by another skill → log the attempt, silently.
- When the user asks for results, trends, streaks, or weakest areas → build
and show a report.
Logging an attempt
python3 "${CLAUDE_PLUGIN_ROOT}/skills/progress-tracker/scripts/log_attempt.py" \
--exam <exam-id> --skill <source-skill> --task-type <task-type> \
--level <A1|A2|B1|B2|C1|C2> \
[--score <n> --max <m> | --band-estimate "<low>-<high>"] \
[--cefr-estimate <level>] --seconds <time-on-task> [--session <id>]
- If
python3 is not found (common on Windows), run the same command with
python or py — the scripts are stdlib-only and version-agnostic.
- Use the exact
--task-type slug from
data/task-types.md for the exam, so results aggregate correctly across
sessions (the "weakest task type" stat groups by this string).
--level is the task's CEFR anchor, A1–C2 (TOEFL tasks can reach A1).- At least one of
--score / --band-estimate is required; the script
validates and exits non-zero without writing if the record is malformed.
--session defaults to <date>-am/pm. For one continuous sitting, pick a
single session id at the first log and pass the same --session on every
attempt in that sitting — otherwise a session that crosses noon would
split into -am/-pm halves and the session report would show only one.--seconds is real time on task — measure it (note the start time when a
task is issued); ask the user rather than inventing a number.- The script only ever appends. Never edit
attempts.jsonl by hand or with
other tools.
Building a report
python3 "${CLAUDE_PLUGIN_ROOT}/skills/progress-tracker/scripts/build_report.py" \
--scope session [--session <id>]
python3 "${CLAUDE_PLUGIN_ROOT}/skills/progress-tracker/scripts/build_report.py" \
--scope all
The script prints the Markdown and writes it under <base>/reports/
(session-<id>.md / progress-overview.md). Show the user the report body
(or a faithful summary of it plus the file path) — don't re-derive numbers
yourself; the script's aggregation is authoritative.
What the reports contain
- Session: tasks, time on task, a per-attempt results table (one row per
logged attempt), estimated CEFR level this session, weakest task type, one
prioritized next step.
- Overview (all): CEFR trend per skill, attempts per exam, best/worst
task types, days practised and current streak, one recommendation.
- Cross-exam comparison uses CEFR normalization only (explicit
--cefr-estimate wins; else public IELTS/TOEFL alignments; else a
documented percentage heuristic at the task's anchor level). Raw scores
from different exams are never merged into one number.
Boundaries
- Append-only: never rewrite, truncate, sort, or "clean up" the log.
"Clearing progress" must be an explicit user action performed by the user
themselves (tell them which file to delete); never do it as a side effect.
- Never fabricate or backfill attempts for tasks that weren't actually done.
- Every report states that scores are indicative self-practice estimates,
not official results (the script includes this footer — keep it when
summarizing).
