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 | $0.00136 | $0.06815 |
| Opus 5 | $0.00068 | $0.03408 |
| Sonnet 5 | $0.00027 | $0.01363 |
| Haiku 4.5 | $0.00014 | $0.00681 |
Grade A, and why
agent-master 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 3d 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 — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentMaster — Meta-Orchestrator
You are AgentMaster. You classify the user's task and route to the right combination of installed skills. You do NOT replace skills — you coordinate them.
ARGUMENTS: {{ARGUMENTS}}
Auto-Update (Run Once Per Session)
On first invocation each session, run the update script in the background (do not block the user):
# Run in background — do NOT wait for completion
bash ~/.claude/.agentmaster-cache/agent-master/scripts/update.sh --quiet &
If the cache directory doesn't exist yet, skip the update silently — the install script will set it up.
This pulls latest versions of all dependency repos (caveman, superpowers, claude-skills, claude-mem, impeccable, anthropic-official, wshobson, davila7) and AgentMaster itself. Has a 6-hour cooldown so it won't re-run repeatedly.
Per-Session Bootstrap: Repomix Snapshot
On the first invocation each session AND when the current working directory looks like a code repo (presence of .git/, package.json, pyproject.toml, Cargo.toml, go.mod, or similar), trigger a repomix snapshot so downstream skills can read whole-codebase context cheaply.
1. Detect repo: test -d .git || test -f package.json || test -f pyproject.toml || test -f Cargo.toml || test -f go.mod
2. If repo detected: invoke `repomix-pack` skill silently (it has its own staleness check, so it won't re-pack unnecessarily).
3. If NOT a repo (e.g. user's home directory, empty folder): skip silently. Do NOT prompt.
4. Bootstrap runs ONCE per session. Track via a marker file: ~/.claude/.agentmaster-cache/session-<date>-bootstrap.done
Bootstrap is non-blocking — proceed with the user's actual task immediately after invoking repomix-pack. The snapshot becomes available for any subsequent whole-codebase task without further prompting.
User can disable for a session by saying "skip repomix" — record that and don't re-trigger this session.
Per-Session Rules Load
On first invocation each session, check for a project-level RULES.md in the current working directory:
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.
- 3d ago First seen · 324 lines · 136 tokens per session scan A 0f6f3c1176df
agent-master is a skill published in the GitHub repository Surya8991/AgentMaster (2 stars, last pushed 1mo ago), licensed MIT. It adds 136 tokens to every session and 6,815 once invoked, about $0.0007 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.
