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 | $0.11918 | $0.11918 |
| Opus 5 | $0.05959 | $0.05959 |
| Sonnet 5 | $0.02384 | $0.02384 |
| Haiku 4.5 | $0.01192 | $0.01192 |
Grade A, and why
AgentMaster copilot-instructions.md scanned grade A with 2 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 2d 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.

agent-master
Meta-orchestrator that classifies tasks and routes to the right combination of installed skills across caveman (output compression), superpowers (dev workflow), anthropic-skills (business/domain expertise), and wired tactical libraries (wshobson, davila7, impeccable, anthropic-official). 26 routing categories including whole-codebase analysis via repomix-pack, LLM/AI app dev, a live task dashboard, meta skill discovery, and curated tactical skill libraries (wshobson, davila7) for backend/security/CI-CD/database depth. Invoke with /agent-master. Use as default entry point for ambiguous or multi-domain requests.
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
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.

AgentMaster copilot-instructions.md is an instructions file published in the GitHub repository Surya8991/AgentMaster (2 stars, last pushed 1mo ago), licensed MIT. It adds 11,918 tokens to every session, about $0.0596 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
