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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

agent-token-saver AGENTS.md 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 yesterday.

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.

What it actually says

Agent Token Saver

Portable context reduction. Hooks stay fail-open; optional tools stay optional.

Commands

  • setup: uv sync --extra dev
  • test: uv run pytest -q
  • lint: uv run ruff check scripts integration tests
  • smoke: bash scripts/neutral_install_smoke.sh
  • live install check: agent-token-saver doctor --profile teams --json

Rules

  • Preserve user changes. No destructive Git.
  • Smallest change. Tests for behavior. ADR for durable design decisions.
  • Public files: no private paths, credentials, PIDs, transcripts or host-only claims.
  • Portable core first. Third-party CLIs are detected, never silently installed.
  • Hook code receives JSON, returns JSON or nothing, and never changes approval, sandbox or stop ownership.
  • No maintenance scan in a hook. synx doctor is manual-only.
  • One controller; workers get one capsule, one oracle, zero or one skill and a compact evidence result. Three independent workers maximum by default.

Product boundary

  • minimal: CLI/ledger only.
  • lean: compact host default, prompt gate, session guard and optional routing/projection CLIs.
  • teams: Lean plus Claude's worker-capsule hook; no automatic fan-out.
  • heavy: opt-in graph/large-context tools for one session.

Codex and Claude use merged JSON hooks plus compact global defaults. Hermes uses a managed block in an existing SOUL.md; GG Coder uses the home AGENTS.md; both retain installed skills for explicit full loading. Verify active configuration with the doctor; files on disk are not proof.

References

  • README: install and user-facing contract.
  • playbook: phase-by-phase usage path and version drift.
  • hooks: host matrix.
  • tooling: default versus optional layers.
  • measurement: method and limits.
Changes

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.
