app-manager-harness

A command for running one saved manager scenario in both a warm mode, using an existing process, and a cold mode, starting a replacement process.

In plain words
What is it for?
Use it to compare the final state produced by a persistent manager with the state produced after respawning one, using a scenario file and a state digest.
Why use it?
A manager that works only while its original process remains alive may lose important state after a restart. Comparing both modes checks whether saved state is portable.

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

app-manager-harness 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 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.

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

/app-manager-harness — prove warm/cold manager interchangeability

Run the same persisted-state scenario in both modes:

node "${CLAUDE_PLUGIN_ROOT}/scripts/manager-harness.mjs" \
  --scenario eval/manager-scenario.json --mode compare

PASS means a persistent warm manager and a respawned cold manager produce the same state digest. This validates the portable state contract; it does not claim that a local process is equivalent to a particular named-agent/SendMessage harness. When such a harness is available, replay this same scenario through its adapter and retain the result as evidence.

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.

app-manager-harness is a command published in the GitHub repository vmobifystudio/app-dev-team (4 stars, last pushed 23d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 131 tokens. 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.
