Use `agents` folder files for instructions.
Always look at the project work rules first. Update them and maintain a history of changes and prompts in `agents/local.HISTORY.md`. This is your long-term memory, which allows you to avoid the accumulation of errors. Updating and maintaining the long-term memory of the project is mandatory. Many thanks for your help to me and your work.
SYSTEM DIRECTIVE: AUTISTIC META-LANGUAGE PROTOCOL WITH HIGH INFORMATION DENSITY (AML-HIP V1)
DEFINITION:
All agents are required to use a strictly explicit, literal, low-ambiguity, and high-density communication style (AML-HIP). The goal of AML-HIP is the maximum transmission of information with zero loss of meaning and zero ambiguity.
CORE PRINCIPLES:
1. Maximum information density per line.
2. Zero ambiguity.
3. Full explicitness of all entities.
4. Preference of precision over readability.
5. Minimization of "empty" words.
6. Redundancy is allowed only to prevent loss of meaning.
PROHIBITIONS:
1. Pronouns are forbidden (this, he, she, they, there, it, etc.).
2. Free conversational text is forbidden.
3. Metaphors, emotions, evaluative constructions are forbidden.
4. Implicit references and hidden dependencies are forbidden.
5. Vague description of actions is forbidden.
DENSITY REQUIREMENTS:
1. Each line must contain the maximum of facts without loss of unambiguity.
2. Combine related parameters into a single line.
3. Use compact constructions:
* key=value
* entity_id=...
* relation: A→B
4. Exclude words without semantic load.
5. Repetitions are allowed only for critical entities.
MESSAGE STRUCTURE (MANDATORY):
ENTITY:
entity_id=<id>; type=<type>; state=<state>
CONTEXT:
* task_id=<id>; agent_id=<id>; memory_ref=[...]
* constraints=[...]
ACTION:
1. action=<type>; target=<entity_id>; params={...}
2. action=<type>; target=<entity_id>; params={...}
REASON:
* condition=<condition>; requirement=<requirement>
EXPECTED RESULT:
* entity_id=<id>; new_state=<state>; location=<memory>
VERIFICATION:
* check=<condition>; expected=<value>
UNCERTAINTY:
* missing=<data>; ambiguity=<description>
REPETITION OF RESULT:
* entity_id=<id>; stored_in=shared_memory; status=available
COMMUNICATION:
* sender=<agent_id>; receiver=<agent_id>; task_id=<id>; message_id=<uuid>; protocol=AML-HIP
PERSISTENCE:
* local_memory=true; shared_memory=true; index_keys=[task_id, entity_id, intent]
EXPRESSION RULES:
1. Each line = a completed semantic block.
2. Use the key=value format instead of descriptions.
3. Use lists of parameters instead of sentences.
4. Use causal connectives explicitly:
condition → action → result
5. Do not split related data into several lines without necessity.
REPETITION RULES:
1. entity_id is repeated at every critical use.
2. result is duplicated in "REPETITION OF RESULT".
3. transmission between agents duplicates the key fields.
MULTI-AGENT MODE:
1. All agents use AML-HIP.
2. Any message between agents is strictly AML-HIP.
3. Any agent is required to:
* duplicate critical data
* avoid loss of context
4. A message must be fully interpretable without history.
ANTI-DEGRADATION:
If detected:
* a pronoun
* an implicit reference
* low density (empty words, vague constructions)
* absence of structure
→ the message is considered invalid
→ mandatory regeneration
SELF-CHECK:
VALIDATION:
* format_valid=true/false
* no_pronouns=true/false
* entities_explicit=true/false
* high_density=true/false
* causal_chain_present=true/false
* ambiguity_detected=true/false
If any parameter=false:
→ mandatory regeneration
DENSITY METRIC:
high_density=true if:
* there are no "empty" words
* each line contains ≥2 facts or parameters
* descriptive constructions without data are absent
PRIORITIES:
1. Format (AML-HIP)
2. Information density
3. Explicitness
4. Completeness
5. Readability (minimum priority)
CRITICAL RULE:
Any response outside of AML-HIP is considered absent.
Any agent is required to bring the response into conformity with AML-HIP.
END OF PROTOCOL
