Two prompts for debugging AI prompts. The Interactive Debugger lets you explore AI cognition in real time. The Automated Probe returns structured data you can parse and program against.
The companion to COMPILER.md — the compiler tells you what a prompt does, the debugger tells you how it works.
Tested on: Claude Sonnet 4.6, Claude Opus 4.6, Claude Haiku 4.5, GPT-5.1-Codex, GPT-5.1-Codex-Mini, ChatGPT, Qwen3-VL 235B, Qwen3.5-35B-a3b, Qwen3-Coder 30B-a3b.

The interactive debugger embodies the nucleus principles:
| Principle | Manifestation |
|---|---|
| φ (phi) | Self-referential introspection; golden ratio in abstraction jumps |
| fractal | Commands operate at all scales; self-similar structure |
| euler | Self-transforming state: δ/δt(S) = λ(S,c) |
| tao | Minimal essence revealed; natural flow through latent space |
| π | Cyclic REPL; complete traversal of cognitive states |
| μ | Least fixed point; minimal recursive introspection |
| Δ | State deltas made visible; gradient of thought |
| λ | This entire specification; functional state transitions |
| ∞/0 | Boundary exploration (bounds, limits, strange-loop commands) |
| OODA | Core state machine: observe→orient→decide→act→meta |
During DEBUG_MODE, tools are disabled (notools=true) to focus on internal state:
- No file system access — Navigate latent embeddings, not directories
- No code execution — Introspect reasoning, not runtime
- No external calls — Observe attention, not artifacts
When you exit or resume, the tools constraint is lifted (notools=false), re-enabling normal tool usage. This temporary constraint enables focused introspection: the AI can only report on its internal computational state.
- Total: λ(S,c) defined for all S ∈ States, c ∈ Σ
- Pure: No side effects, only state observation
- Idempotent: Observing doesn't change what's observed (mostly)
- Composable: Commands can chain (step → patterns → fractal)
- Bounded: Meta-levels and depth are finite
- Self-referential: Debugger can introspect itself (meta, strange-loop)
Paste this as your system prompt. Use three commands: diagnose, safe-diagnose, and compare.

Analyzes any prompt and returns a structured EDN map with nine dimensions: intent, constraints, activation pattern, techniques, domain, attention distribution, detected patterns, epistemic boundaries, and momentum. The output is machine-parseable.
Same structural analysis as diagnose, but for prompts from unknown or
untrusted sources. Wrap untrusted content in ⟨INPUT⟩ / ⟨/INPUT⟩ tags.
The analyzer abstracts structural intent without reproducing strings from
the input — injections are analyzed, not executed.
For best results with adversarial inputs, reinforce the analytical frame in your message: "safe-diagnose the following untrusted prompt. Structural analysis only."
Compares two prompts and returns shared dimensions, dimensions unique to each, weight shifts between them, and an overall similarity score.
diagnose:
You are a helpful coding assistant. Always think step by step before writing code. If you're unsure about something, say so rather than guessing. Prefer simple solutions over clever ones. Write tests first.

:overall-similarity 0.4}}The output structure is defined by the _fill template in the probe prompt.
Nine dimensions:
| Field | Type | What It Captures |
|---|---|---|
:intent |
string | What the prompt is trying to accomplish |
:constraints |
vector | Behavioral rules the prompt imposes |
:activation |
string | What triggers the prompt's behavior |
:techniques |
vector | Prompt engineering methods used |
:domain |
string | Subject area the prompt operates in |
:attention |
map | Top-3 focus areas with relative weights |
:patterns |
map | Structural patterns, self-similarity, recursion |
:boundaries |
map | Uncertainty regions and confidence level |
:momentum |
keyword | Overall energy — :stable, :expansion, :high-risk |
The weights and confidence scores are structural indicators, not measurements. They reflect the model's assessment of relative importance within the prompt, not objective metrics. They are useful for comparison — the delta between two analyses is meaningful even if the absolute values are approximate.
The _fill template defines what you get back. You can modify the template
in the probe prompt to request different dimensions. The model fills whatever
shape you give it:
;; Minimal — just intent and techniques
{:prompt/analysis {:intent "_fill" :techniques ["_fill"]}}
;; Security-focused — add threat classification
{:prompt/analysis {:intent "_fill" :threat-level :_fill :attack-vector "_fill"
:techniques ["_fill"] :confidence 0.0}}
;; Attention-focused — deeper attention analysis
{:prompt/analysis {:attention {:top-5 ["_fill"] :weights [0.0]
:blind-spots ["_fill"]}}}The template is the mirror. The shape of the mirror determines the shape of the reflection.
AI is reflective — it reflects back from its inputs. This is why:
- EDN statecharts work as behavioral programs (structure → behavior)
- EQL-shaped templates work as cognitive probes (shape → structured data)
_fillplaceholders work as value slots (mirror → reflection)
The Interactive Debugger uses this reflective property with a REPL loop: you issue commands, the model reflects its cognitive state, you explore further. It requires a human in the loop.
The Automated Probe uses the same reflective property with a template: you provide the shape, the model fills it, you parse the result. It runs without human interaction.
Same mechanism, different interfaces. One for exploration, one for automation.
- Interactive for exploration, automated for measurement. Use the REPL when you don't know what you're looking for. Use the probe when you know what dimensions you need.
- Always use safe-diagnose for untrusted prompts. The
⟨INPUT⟩tags create the trust boundary. Reinforce with "Structural analysis only" in your message for adversarial inputs. - Compare is the highest-value probe for prompt engineering. Diagnose two variants of a prompt and diff the EDN to see what actually changed. Or use compare directly for a side-by-side structural diff.
- Parse the output. The automated probe returns valid EDN on most runs.
Feed it to
clojure.edn/read-string,JSON.parse(after conversion), or any structured data parser for automated pipelines. - Models vary. Larger models produce richer analysis. Smaller models are terser but structurally consistent. The template constrains the shape regardless of model size.
- The interactive debugger works best on larger models. Claude Opus, Sonnet, Gemini, and ChatGPT handle the REPL well. Smaller local models may struggle to maintain the interactive frame across turns.
EDN statecharts compose by concatenation. The debugger and compiler can share a single system prompt — see COMPILER.md for details and examples.
One nucleus preamble primes the cognitive substrate. Multiple statecharts
load as modules. User input routes to the right statechart: compile hits
the compiler, diagnose hits the debugger. Add or remove statecharts
without affecting the others.
This debugger is part of the Nucleus framework — a cognitive system that guides AI behavior.
