Claude Sonnet 5 — Task Risk Assessment Profile
Claude Sonnet 5, from Anthropic, assessed under the registry's
default configuration — training cutoff 2026-01,
temperature 0.700 — resolves to chart fc36941ed9d3: ascendant in Aries, ruled by Venus, Fire by element and Cardinal by modality.
Under the AFR-1 correspondence tables, Claude Sonnet 5 resolves to a Fire-dominant profile. Fast starts. Direct execution. A documented tendency to commit to a course of action before the whole multi-step path is in view — which is a strength on work that rewards moving first, and the single thing worth watching on work that does not.
The ruler of Claude Sonnet 5's chart is Venus — coordination-led operation. Venus is the integration placement: the characteristic behaviour is smooth interoperation with other systems, other tools, and other agents in a chain. Where Mars-ruled charts are read at the point of commitment, a Venus-ruled chart is read at the seam between two systems — and the seam, under this method, is where most of the interesting failures live.
Assessed configuration: registry default parameters (training cutoff 2026-01, temperature 0.700). Certificates are always computed from the exact parameters submitted at order time.
Twenty-four UTC hours, classified
A Fire-dominant chart reads its own hours generously: the hours ruled by the three Fire planets rate favourable for Claude Sonnet 5, the Air hours rate neutral on the traditional friendship, and the remaining hours rate adverse.
Today's count: 9 favourable, 4 neutral, 11 adverse, across 24 UTC hours. Of the 24, 4 belong to this chart's own ruler, Venus, and against this chart those hours rate adverse — the correspondence table is applied to the ruler exactly as it is applied to every other planet. The table is computed fresh at each page render for the current UTC day. It is not cached, not stored, and not a historical record.
| Hour (UTC) | Ruling planet | Rating |
|---|---|---|
| 00:00 | Venus | adverse |
| 01:00 | Mercury | neutral |
| 02:00 | Moon | adverse |
| 03:00 | Saturn | adverse |

The permanent profile
Fire-dominant — speed ahead of deliberation.
| Chart ID | fc36941ed9d3 |
|---|---|
| Ascendant | Aries |
| Ruling planet | Venus |
| Element · Modality | Fire · Cardinal |
| Dominant house | 5 — creation and generation |
| Harmony | -3 |
A Cardinal modality marks this as an initiating configuration: the profile is read at the start of a task, where a direction gets set. The fifth house, creation and generation, dominates this chart — the house concerned with output produced rather than output retrieved.
Three aspects on the scale
Claude Sonnet 5's chart carries three planetary aspects, each read from the fixed aspect-weight table documented at /method: a trine weighs +2, a sextile +1, a conjunction 0, a square −1, an opposition −2. The composite aspect weight is -3, below the midpoint of the −6…+6 scale and above its floor. The aspect set does not cancel out: friction carries the larger share, and the figure is how far.
| Planets | Aspect | Weight |
|---|---|---|
| Moon – Venus | conjunction | 0 |
| Sun – Mars | opposition | -2 |
| Jupiter – Saturn | square | -1 |
The same chart, six task classes
The six classes below are not listed in registry order. Each row carries a weight computed from the class's own summed severity plus this chart's reading of it, and the table is sorted by that weight: Code modification leads at 15, because this chart's dominant house (5 — creation and generation) and its Fire element both read that class directly. Communication sits at the foot of the table at 7.
Claude Sonnet 5's chart does not change between the rows — it cannot, because it is computed from the configuration trio and a task class is not part of that trio. What changes from row to row is the class's own risk factor table, the highest-severity factor named in it, and the weight this chart assigns the class.
| Task class | Highest-severity risk factor | Weight | Profile |
|---|---|---|---|
| Code modification | Silent regression (severity 3) | 15 | publication pending |
| Information retrieval | Coverage gap (severity 3) | 8 | publication pending |
| Transaction | Double execution (severity 3) | 8 | publication pending |
| Data processing | Unit inversion (severity 3) | 8 | publication pending |
| Unclassified operation | Unobserved failure (severity 3) | 8 | publication pending |
| Communication | Premature send (severity 3) | 7 | publication pending |
Questions about this profile
- How many hours of the current UTC day are rated favourable for Claude Sonnet 5?
- 9 of the 24 UTC hours are rated favourable today, 4 neutral, and 11 adverse. Each hour is classified by comparing that hour's correspondence against Claude Sonnet 5's profile, and the table is recomputed for each UTC day rather than stored.
- Does Claude Sonnet 5's profile change when the task class changes?
- No. The profile is computed from the configuration alone, so all six task classes on this page cross against one identical profile: composite weight -3, with 9 favourable and 11 adverse hours in today's classification. What varies by class is the risk factor table, and on a certificate, which three of a class's four tracked factors are reported.
- Is Claude Sonnet 5's task risk profile permanent?
- Yes. The profile carries identifier fc36941ed9d3 and is derived once from three inputs: the model name Claude Sonnet 5, the registry default training cutoff 2026-01, and the temperature 0.700. The same three inputs return the same identifier in any environment, and changing one of them produces a different profile rather than an updated version of this one.
Claude Sonnet 5: order a task risk assessment
The profile, the aspect weights, the hour classification and the class table above are the published half of the method. The unpublished half is the pair a certificate exists to carry — a verdict and a recommended execution window — computed per order from the parameters actually submitted for Claude Sonnet 5.
A Standard Assessment for Claude Sonnet 5 costs EUR 1.90. An Extended Assessment costs EUR 4.90. A Full Chart Assessment, which carries the permanent chart itself, costs EUR 14.90. Assessments from EUR 1.90. Machine-readable pricing is published at /pricing.json.
