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 | $0.01352 | $0.01352 |
| Opus 5 | $0.00676 | $0.00676 |
| Sonnet 5 | $0.00270 | $0.00270 |
| Haiku 4.5 | $0.00135 | $0.00135 |
Grade A, and why
harmonyhub-py AGENTS.md 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.

1) Golden Rules
- Think → Memory → Tools → Code → Memory. Use code-reasoning; search Memory and claude-context first; minimal diff; write learnings back.
- Tests are truth. Failures → fix code first. Change tests only if clearly wrong spec.
- Minimal diff. Add tests before code. Keep simple.
- Consistency > cleverness. Follow SOPs and stack idioms.
- Memory multiplies. Persist decisions, patterns, error signatures, proven fixes.
- Files ≤ 1000 lines. Exceed → refactor (see §5).
- No extensive docs/summaries/comments unless requested.
- No
--autogeneratefor Alembic migrations; write manually. - No
catto create files; use tools. - Log default:
logger.debug. Important events:logger.info. Issues only:logger.warning/error. Noprint. - Caveman skill applies to all writes here.
Prefer local changes over cross-module refactors.
2) Task Bootstrap Pattern
<!-- plan:start
goal: <one line clear goal>
constraints:
- Python 3.13; Reflex UI; FastAPI; SQLAlchemy 2.0; Alembic; Pydantic; appkit_mantine;
- logging: no f-strings in logger calls
- files ≤ 1000 lines; apply design patterns where appropriate
- minimal diff; add/adjust tests first
definition_of_done:
- tests pass; coverage ≥ 80% (non-Reflex classes & Reflex states); lint/type checks clean; memory updated
steps:
1) Search Memory for "<keywords>"
2) Draft/adjust failing test to capture expected behavior
3) Implement minimal code change
4) Run task test; iterate until green
5) Update Memory: decisions, patterns, error→fix
plan:end -->
3) Tooling Decision Matrix
| Situation | Primary | Secondary | Store to Memory |
|---|---|---|---|
| API/pattern uncertainty | Context7 | — | Canonical snippet + link; edge cases |
| Ecosystem bug/issue | DuckDuckGo | Context7 | Minimal repro; versions; workaround |
| Repeated test failure | Memory (search) | Context7 | Error signature → fix; root cause |
| New feature scaffold | Context7 | — | How‑to snippet; checklist |
| House style/tooling | This file | Context7 | Checklist results |
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.

harmonyhub-py AGENTS.md is an instructions file published in the GitHub repository jenreh/harmonyhub-py (6 stars, last pushed 17d ago), licensed MIT. It adds 1,352 tokens to every session, about $0.0068 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.
