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 | $0.00079 | $0.01447 |
| Opus 5.5 | $0.00032 | $0.00579 |
| Sonnet 5.5 | $0.00016 | $0.00289 |
| Haiku 4.5 | $0.00008 | $0.00145 |
Grade A, and why
time-awareness 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 25d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Time awareness
claude-timestamp tells you about time in short system reminders or hook context. They state facts and nothing else. This is what to do with them.
The reminders
Message sent at local time 10:37:21 CEST, after a 3h break arrives with
every prompt. It is when the user pressed enter, not the time now.
Turn running 30m04s (prompt sent 10:37:21); now 11:07:25 CEST. means the
turn you are in has run that long without hearing from the user.
- Check that the work still matches what was asked. Drift costs less to catch now than at the end.
- From the second one onward, consider finishing the step you are on and reporting back instead of opening new scope. That is a judgement call: a long job the user asked you to run unattended should keep going.
That Bash call took 2m14s. means one call was slow. Before running the
same thing again:
- run it with
run_in_backgroundand keep working meanwhile, - narrow it: one test file, one package, a filter, or
- reuse the output you already have, when nothing it depends on has changed.
Previous session in this project ended 14h ago (Thu 20:12:05). and
Resuming this conversation; last activity 14h ago (Thu 20:12:05). mean
that what you knew before the gap may be stale. Before building on it, check
what could have moved: the branch and git status, running servers, open
pull requests and CI runs, and files the user may have edited meanwhile.
Conversation compacted. Session started 09:12:05 (3h04m ago), 41 turns so far, 1h02m of it waiting. Longest turns: 10:37:21 (22m04s), 14:05:10 (15m30s).
arrives after a compaction. The summary you are working from has no clock;
this line is the measured timeline. Use it, or --turns, when the user asks
what happened when, rather than reconstructing times from the summary.
Before a slow command or a wait
Usually slow in this project: bash tests/run.sh ~4m02s (12 runs).
arrives at session start, and That Bash call took 6m10s (usually 4m02s).
when a call was slow. Both come from measured runs in this project.
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.

time-awareness is a skill published in the GitHub repository AraneaDev/claude-timestamp (3 stars, last pushed 16d ago), licensed MIT. It adds 79 tokens to every session and 1,447 once invoked, about $0.0003 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 2026-09-12.

Suggest a weekly training structure from recent load and deliver the plan.
fresh-start
Continue in a new chat without losing anything — writes a compact handoff to paste into a fresh conversation. Use whenever the user wants to move to a new chat or conversation, hits usage limits, says replies got slow or Claude forgets earlier details, or the conversation has grown long.
token-check
Estimate how many tokens a pasted text, an attached file or the conversation so far takes, what it means for the context window and usage limits, and how to cut it. Use when the user asks how big something is in tokens, why they keep hitting limits, or whether a file is too large to send.
folder-flattening
Verschachtelte Ordnerhierarchien in flache, maschinenlesbare Strukturen umbauen. Bash-basiert mit intelligenter Merge-Logik.

Ask which orc command, skill, or flow fits your situation — the router over everything orc ships.
ccc-adhd
Answer-first output: the fix, then command, then file:line, context last. Toggle on, off or status; stacks with caveman. Based on ayghri/i-have-adhd (MIT). Use when the user wants the answer first.
