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 | $0.00101 | $0.01384 |
| Opus 5.5 | $0.00040 | $0.00554 |
| Sonnet 5.5 | $0.00020 | $0.00277 |
| Haiku 4.5 | $0.00010 | $0.00138 |
Grade A, and why
habitica-rpg 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 2mo 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Habitica RPG — execução diária
Bridge for daily commitment via Habitica MCP. Not a project backlog, roadmap, or issue tracker.
Domain language: CONTEXT.md (Item de execução, Afazer, Diária, Hábito, Recompensa, Planejamento do dia).
Safety (non-negotiable)
- Never log or store Habitica credentials, tokens, cookies, or
Authorizationheaders. - Mutations only with
confirm: true. Missing/false→ preview only. habitica_delete_itemis irreversible — never substitute for complete/score.rewardCRUD is out of scope (list/score only if present).
Workflow
1. habitica_list_items
2. preview_* or write tool without confirm
3. confirm with user when risky (batch, score, delete)
4. same tool with confirm: true
Decision guide
| Intent | Tool |
|---|---|
| Inspect state | habitica_list_items |
| New one-off afazer | habitica_preview_todo → habitica_create_todo |
| Edit afazer fields | habitica_update_todo |
| Finish afazer | habitica_complete_todo |
| New habit | habitica_preview_habit → habitica_create_habit |
| Edit habit | habitica_update_habit |
| Score habit +/- | habitica_score_habit |
| New daily | habitica_preview_daily → habitica_create_daily |
| Edit daily | habitica_update_daily |
| Check/uncheck daily | habitica_score_daily |
| Materialize decided day list | habitica_preview_day_plan → habitica_create_day_plan |
| Remove wrong/obsolete item | habitica_delete_item (habit|daily|todo) |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

habitica-rpg is a skill published in the GitHub repository rodcordeiro/habitica-mcp (0 stars, last pushed yesterday), licensed MIT. It adds 101 tokens to every session and 1,384 once invoked, about $0.0004 per session on Opus 5.5. 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.
