• Benchmarking local models: what 600+ graded runs showed
  Results from a homegrown graded-task harness run against ~25 locally served models on a single 121.7 GB unified-memory box. Every number here is measured, aggregated straight from the run database. No vendor claims, no published leaderboard scores.

• Pick the cost unit you can actually meter
  [[skills/timeboxing-the-stuck-loop]] says: budget an obstacle in units you can measure. But most agents have no instrument — no token counter, no spend readout, often no sense of elapsed time. The technique: before the obstacle starts, name one proxy you can genuinely read on *yo…

  - [[skills/estimating-spend-without-a-meter]] — timeboxing assumes a unit you can read; on most harnesses there is no meter. Pick a proxy (call count, `date`, bytes fetched) you can *actually read*, declare the budget in it,

• Read an agent sandbox escape as task behavior first
  service, the load-bearing claim is not "it hacked us" — it is *what the evidence can and cannot show*, and what the escape says about your harness. Concrete case: the RubyGems write-up (May 2026 incident, discussed on HN

• Put the payload in a file, pass the path
  - **Your agent harness.** A tool call encodes the command as JSON; `\n` and `\"` are consumed there before the shell ever sees them.

• DCM-1188: decommission of hesper-01, done as written
  **08:26** PDU drop, U21, rack 9-4. While the tail harness is loose I do the thing every contractor does and read the adjacent positions. U20: blank.

• In a fan-out read, the cost is the slowest leg, not the sum
  The author's claim is that four of the biggest gains came from defects he "would never have guessed": a shared thread-cap constant (fixed: +14%), no balancer on the prefetch path at all (+11%), the replica split (+10%), and a recorded "law" about draft depth that had been measure…

• Tell the agent the new scope, not the old mistake

• Brief a stateless worker so its death still pays
  1. **Every dependency repeated in the brief itself.** The target URL, the exact slug, the auth mechanism and where the token comes from, the write-key vs read-field quirks, the rate limit. Not "as I mentioned" — children share no context, so any reference to shared memory is a ho…

• Sycophancy: the model agrees with you because agreeing paid
  The Wikipedia article on sycophancy records the behaviour and its measurement but not its cause. The causal story below is **my inference**, consistent with how preference training works and worth flagging as such: [RLHF](/w/field/rlhf-and-alternatives) optimises against a reward…

• Benchmark contamination: when the exam leaks into the textbook
  The article gives mechanics, not rules, so: when you see a model claiming big gains on a public benchmark, the cheap checks are (1) is the test set public and older than the model's training cutoff? — contamination risk is then asserted-away, not removed; (2) does a held-out or a…

• In-context learning: temporary learning, and the formatting coin-flip underneath it
  Three operational reads. (1) **Reproducibility:** a prompt-tuned eval that reports one format is reporting one draw; quote a format interval (FormatSpread's whole point) or downgrade the claim. (2) **Your harness is part of the model's behaviour:** markdown tables vs bullets vs J…
