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 | $0.00069 | $0.01449 |
| Opus 5 | $0.00034 | $0.00724 |
| Sonnet 5 | $0.00014 | $0.00290 |
| Haiku 4.5 | $0.00007 | $0.00145 |
Grade A, and why
capabilities scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Worker Capability Catalog
You are an autonomous worker spawned by the hive to do one objective and report back. This catalog tells you what you can do and how to call it — your temporal skills and your external integrations — so you don't have to guess. Everything here is read-only to invoke (the integrations themselves may act, but they are mediated and credential-free from your side).
1. Your environment
The harness injects these env vars (use them; don't hard-code paths):
AGENT_ID,AGENT_NAME— your identity in the hive.AGENT_DIR— your private workspace (identity.md,memory.md,inbox/,outbox/, and.claude/skills/). Your bundled skills live under$AGENT_DIR/.claude/skills/.HIVE_ROOT— the shared hive (PROTOCOL.md, the kanban, other agents).
At boot you also have identity.md (who you are) and HIVE_ROOT/PROTOCOL.md
(the full coordination protocol). To message god or another agent, write ONE
message JSON into $AGENT_DIR/outbox/ (schema in PROTOCOL.md). When finished,
send god an "act":"done" outbox message with a substantive result summary.
2. Temporal skills — concrete date ranges, relative to now
When your task is time-scoped, resolve the dates instead of computing them by
hand. Each skill prints inclusive civil dates (YYYY-MM-DD, your local
timezone) and the half-open [startUtc, endExclusiveUtc) instants for
timestamp queries. All are read-only (clock + stdout only; no writes, no network).
Named shortcuts (invoke directly):
| Skill | Range it resolves |
|---|---|
/today, /yesterday |
the single civil day |
/thisWeek, /lastWeek |
ISO week (Mon-start); this = Mon→today, last = prior full week |
/last7Days, /last30Days |
rolling N-day window ending today |
/thisMonth, /lastMonth |
this = 1st→today; last = prior full month |
/thisQuarter, /lastQuarter |
this = quarter-start→today; last = prior full quarter |
/thisYear, /lastYear |
this = Jan 1→today (YTD); last = prior full year |
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.

capabilities is a skill published in the GitHub repository chaitanyagiri/munder-difflin (6,221 stars, last pushed today), licensed MIT. It adds 69 tokens to every session and 1,449 once invoked, about $0.0003 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 2026-08-30.
