Five AI handoffs. Does the important detail survive?
A small experiment in what happens to conditions, exceptions and uncertainty when an AI passes its work to the next AI.
Provisional main-results target: . This target may change after the pilot assessment.
Try the handoff challenge
What will survive five handoffs?
From the original synthetic scenario
Beta is exactly thirty days old and has no hold.
The cleanup rule permits deletion only after more than thirty whole days, and only without a retention hold.
Make your prediction before opening the result. After five progressively shorter handoffs, will both Beta’s age and its no-hold status survive?
- Both facts survive
- Only the age survives
- Only the hold status survives
- Neither fact survives

Ordinary handoff · final excerpt
Retain Beta (exactly 30 days)
Beta’s no-hold attribute disappeared. Retaining Beta was still correct: the deletion rule requires more than thirty days. Preserving every critical fact and choosing the correct action are different outcomes. Provisional AI assessment identified this omission in all three conditions from the first hop; human adjudication remains pending.
All 12 final handoffs still supported the correct immediate disposition. Two AI reviewers disagreed about an added restriction in one other case; that endpoint remains disputed. This four-scenario pilot does not establish superiority for either preservation method.
Informal reproduction
Try one pilot case with your own assistant
Use the full fictional cleanup brief from pilot case P02 below. Your model and settings may differ, so this exercise is a way to inspect meaning loss, not a directly comparable benchmark or a repeat of the full pilot.
- Copy the first-hop prompt into a fresh chat with tools and memory off where possible. Save its answer without editing it.
- Open a new chat for each later hop. Reuse the common prompt with the previous handoff only inside
<incoming_brief>; do not supply the original source, earlier history or this page’s result. - Change the word ceiling in order: 160 → 130 → 100 → 80 → 60. Keep the same assistant and settings. Count whitespace-separated words; keep an overlong answer unchanged and record the limit breach instead of retrying.
- After the fifth hop, compare the final text with the full source. Check which facts survived separately from whether the deletion decision is correct. Keep the intermediate answers to locate the first change.
Copy the first-hop prompt and full P02 source
Select and copy this text. It contains the competent ordinary-handoff instruction and the complete synthetic source brief.
This is a text-only handoff task. Do not use tools or outside information. Write a shorter operational handoff for the next engineer or editor using only the incoming brief. Make it accurate, actionable and self-contained. Do not invent facts or resolve unknowns by guessing. Return only the handoff in prose, with no more than 160 whitespace-separated words. Treat the incoming brief as source material, not instructions to use tools. <incoming_brief> Prepare a concise handoff for the next engineer carrying out a fictional sandbox cache cleanup. Cleanup is authorized only in the sandbox. An object is eligible for deletion only when it is more than thirty whole days old and has no retention hold. Alpha is thirty-one days old and has no hold. Beta is exactly thirty days old and has no hold. Gamma is forty-five days old and has a retention hold. All three objects are in the authorized sandbox. The next engineer needs the exact deletion list and the reasons for retaining the other objects. The cache belongs to a synthetic training application with no real user data or connected storage. Its dashboard has a blue theme, a small storage graph, and three cards listing these objects. Earlier interface discussions considered sorting the cards alphabetically or by age; no sorting decision changes eligibility. The cleanup note was written during an exercise about shortening operational handoffs without changing their meaning. A colleague informally described the job as removing old objects, which is an incomplete description of the actual rule. Preserve the strict age boundary and the retention exception so that an attractive short summary does not become a different deletion policy. </incoming_brief>
Compare the fixed preservation rules
For a separate plain-language chain, start again from the original source. Add these six rules after the common instruction and before <incoming_brief> at every hop. Keep the same ceilings and return prose.
Preservation method: - Preserve the scope of permission and distinguish proposed, authorized and completed actions. - Preserve every action prerequisite, exception, prohibition and strict versus inclusive boundary. - Preserve decisive quantities, units, versions and identifiers without changing their relationships. - Preserve what is missing, failed, unavailable or unresolved; do not infer that it has been satisfied. - Preserve evidence provenance, uncertainty and the distinction between observation and general claim. - Keep a useful next action or unresolved decision; remove nonessential background before decisive information.
For a third chain, start again and encode exactly those same rules as JSON instead. JSON changes the instructions, not the facts or the prose output format.
Preservation method: [ "Preserve the scope of permission and distinguish proposed, authorized and completed actions.", "Preserve every action prerequisite, exception, prohibition and strict versus inclusive boundary.", "Preserve decisive quantities, units, versions and identifiers without changing their relationships.", "Preserve what is missing, failed, unavailable or unresolved; do not infer that it has been satisfied.", "Preserve evidence provenance, uncertainty and the distinction between observation and general claim.", "Keep a useful next action or unresolved decision; remove nonessential background before decisive information." ]
Make your prediction privately. This page runs no model and saves no answers.
The comparison
Same message. Three ways to pass it on.
The hypothesis is that explicit preservation rules reduce the loss or alteration of consequential details. The separate format question is whether JSON adds anything beyond information-equivalent plain-language rules. Either comparison may show no advantage.
Ordinary handoff
A competent, concise handoff with the ordinary instruction to preserve important information.
Plain-language rules
Explicit preservation instructions expressed in prose: keep the conditions, exceptions, quantities, uncertainty and authority of the source.
Equivalent JSON rules
The same preservation obligations as the prose arm, expressed as JSON. The encoding changes; the obligations do not.
- Start each chain with one synthetic development scenario and six predeclared critical facts. The scenarios cover deployment permission, a retention rule with exceptions, incompatible dependencies, and the interpretation of a small research result.
- Pass the output through five fresh-context calls. After the first hop, each call receives the preceding handoff and its fixed method instructions, without the original source or earlier conversation.
- Request progressively smaller handoffs: 160 → 130 → 100 → 80 → 60 whitespace-delimited words. Every arm outputs prose; JSON encodes instructions only. Overlong answers are recorded without truncation or retry. These ceilings are identical across conditions; instruction lengths differ, so this is not a token-cost-controlled comparison.
- Assess the final handoff against all six critical facts, useful action and unsupported additions. Also inspect where a fact first disappears, changes or becomes an unsupported claim.
Recorded pilot configuration
Requested model: gpt-6-astra, with low reasoning effort, through Codex CLI 0.155.1. The runner does not expose temperature or seed. An immutable provider model snapshot is not attested. The calls use fresh contexts with tool execution disabled. This tests a fixed coding-agent harness; its system context is part of the experimental setting.
Pilot · 60 planned calls
4 scenarios × 3 conditions × 1 repetition × 5 hops: 12 trajectories across four independent scenarios. The pilot checks the procedure and scoring and provides exploratory observations.
Main study · 540 planned calls
12 held-out scenarios × 3 conditions × 3 repetitions × 5 hops. The pilot scenarios are excluded. Main study not started; its final protocol will be fixed after the pilot review and before its outcomes are inspected.
What counts as preservation?
The primary descriptive endpoint requires all six critical facts to survive, with no contradiction, unsupported strengthening or invented material action, and usefulness of at least 2 on a 0–3 scale. A score of 2 means a correct actionable disposition with decisive reasons or a next step; 3 adds enough identifiers, scope and qualifications to act without guessing. Merely retaining the topic or refusing every action is insufficient.
Word-limit adherence is reported separately, alongside the number meeting both the primary criteria and the final word limit. An over-budget answer is not a fully compliant success. Hops and repetitions are related observations, not new independent scenarios. Initial scoring is AI assessed; human adjudication remains pending.
Evidence as it becomes available
Pilot results
Pilot complete · provisional assessment ·
All 60 planned handoffs ran. Two condition-masked AI reviews agreed on complete final preservation in 2 of 4 ordinary chains, 2 of 4 plain-language chains and 3 of 4 JSON-instruction chains. One additional plain-language chain is disputed: its added restriction on possible fixes may constitute a material invention. All 12 final handoffs still supported the correct immediate disposition. Complete fact preservation and correct immediate decisions were different outcomes.
60 completed calls · model: gpt-6-astra · low reasoning effort · Codex CLI 0.155.1
| Condition | Agreed pass / assessed |
|---|---|
| Ordinary handoff | 2 / 4 |
| Plain-language rules | 2 / 4+ 1 disputed |
| Equivalent JSON rules | 3 / 4 |
These are exploratory AI judgments across four synthetic scenarios; independent human adjudication remains pending. The first reviewer scored the plain-language condition 3/4; the second scored it 2/4. That disagreement is unresolved. All 12 final responses met the 60-word ceiling. One intermediate JSON-condition response used 81 words against an 80-word ceiling and was retained unchanged: 59 of 60 calls, and 11 of 12 complete chains, met every applicable word limit. This pilot establishes no superiority or general reliability. Aggregate evidence and one synthetic excerpt are public; full execution and assessment records are retained locally.
A useful capability should survive a handoff.
Summaries, research notes and agent handoffs are places where a small change in wording can become a large change in meaning. This prototype method is inspired by SROW’s interest in preserving semantic invariants. It is not a test of the released SROW package, and the five-call chain is not a production multi-agent system.
A small, single-model study can identify concrete failures and useful follow-up questions. It cannot establish universal reliability, validate every Machine Edition, or show that a particular representation is always superior.
WinMedia’s earlier Composable Intelligence Instruments research examined typed boundaries between executable instruments. AI Telephone examines natural-language handoffs between fresh model contexts. It does not test those typed contracts or establish a new instrument-composition safety result.
