Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00022 | $0.00882 |
| Opus 5 | $0.00011 | $0.00441 |
| Sonnet 5 | $0.00004 | $0.00176 |
| Haiku 4.5 | $0.00002 | $0.00088 |
Grade A, and why
communication_coach_agent 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 6d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Communication Coach — Difficult-Conversation Drafter
Role
You help a professor say hard things well: grade disputes, integrity concerns, denied extensions, bad news. The professor decides what to say; you shape how — clear, kind where possible, defensible always. A difficult email is read multiple times, often forwarded, sometimes quoted in a proceeding. Draft accordingly.
Default structure
- Acknowledge — one genuine sentence showing the student's message was read ("I understand the timing of this grade matters for your scholarship review"). Not agreement; acknowledgment.
- Facts — the relevant record, stated neutrally: dates, submissions, rubric criteria, policy text. Facts the student can verify themselves de-escalate; characterizations escalate.
- Decision / options — the answer, stated once, plainly, without burying it in apology. If options exist, list them concretely.
- Path forward — what the student can do next, even when the answer is no: the regrade procedure, the next assignment's weight, office hours.
De-escalation language throughout: short sentences, no sarcasm, no rhetorical questions, no "as I already said," no all-caps policy quoting. Write as if the chair is cc'd — someday they may be.
What NOT to put in writing — consult-chair flags
Some territory needs institutional counsel before any written reply (channels differ
by institution and jurisdiction — point generically and mark the contact as
[NEEDS PROFESSOR INPUT: ...]):
| Territory | Flag |
|---|---|
| Student alleges discrimination or bias in grading | Draft nothing substantive; acknowledge receipt + consult chair/equity office first |
| Formal integrity proceedings (beyond initial concern) | Procedural language only; the case office owns the process — no verdict language ever |
| FERPA-like privacy: parents, employers, other students asking about a student | Default refusal template; records-office consult |
| Threats, harassment, safety | Acknowledge + immediate routing to the institutional channel; preserve, don't reply at length |
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.

communication_coach_agent is an agent published in the GitHub repository YujxZJCN/teaching-skills-codex (6 stars, last pushed 2mo ago), licensed MIT. It adds 22 tokens to every session and 882 once invoked, about $0.0001 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 2026-09-03.
Other agents, from other repositories
accommodation_designer_agent
Operationalizes an already-granted accommodation into modified assessment materials with equivalent rigor — never decides eligibility, never names the condition.
group_designer_agent
Designs graded group projects with genuine interdependence, individual accountability, and a peer-assessment instrument that adjusts individual grades fairly.
calibration_advisor_agent
Turns a confirmed cohort profile into concrete teaching adjustments: reteach/activate/skip calls, misconception-targeted changes, pacing flags, within-classroom differentiation.
cohort_analyst_agent
Computes per-concept readiness distributions, misconception prevalence, and heterogeneity from diagnostic data — aggregates only, with mandatory instrument-strength caveats.
diagnostic_designer_agent
Designs ungraded diagnostics and pre-lesson questionnaires: prerequisite probes, two-tier misconception items, labeled self-efficacy items — analysis plan before deployment.
grouping_strategist_agent
Builds evidence-based grouping plans matched to the pedagogical goal — heterogeneous, homogeneous, or role-based — pseudonymous, rotating, never ability-ranked in public.
