Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.04052 |
| Opus 5 | $0.00026 | $0.02026 |
| Sonnet 5 | $0.00011 | $0.00810 |
| Haiku 4.5 | $0.00005 | $0.00405 |
Grade A, and why
bdi-mental-states scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
98% identical to bdi-mental-states — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

BDI Mental State Modeling
Transform external RDF context into agent mental states (beliefs, desires, intentions) using formal BDI ontology patterns. This skill enables agents to reason about context through cognitive architecture, supporting deliberative reasoning, explainability, and semantic interoperability within multi-agent systems.
When to Activate
Activate this skill when:
- Processing external RDF context into agent beliefs about world states
- Modeling rational agency with perception, deliberation, and action cycles
- Enabling explainability through traceable reasoning chains
- Implementing BDI frameworks (SEMAS, JADE, JADEX)
- Augmenting LLMs with formal cognitive structures (Logic Augmented Generation)
- Coordinating mental states across multi-agent platforms
- Tracking temporal evolution of beliefs, desires, and intentions
- Linking motivational states to action plans
Do not activate this skill for adjacent work owned by other skills:
- General context-window explanations or attention mechanics:
context-fundamentals. - Persistent user, entity, or conversation memory without formal BDI state:
memory-systems. - Supervisor, swarm, or handoff topology decisions:
multi-agent-patterns. - General agent evaluation rubrics or quality gates:
evaluation.
Core Concepts
Mental Reality Architecture
Separate mental states into two ontological categories because BDI reasoning requires distinguishing what persists from what happens:
Mental States (Endurants) -- model these as persistent cognitive attributes that hold over time intervals:
Belief: Represent what the agent holds true about the world. Ground every belief in a world state reference.Desire: Represent what the agent wishes to bring about. Link each desire back to the beliefs that motivate it.Intention: Represent what the agent commits to achieving. An intention must fulfil a desire and specify a plan.
Mental Processes (Perdurants) -- model these as events that create or modify mental states, because tracking causal transitions enables explainability:
BeliefProcess: Triggers belief formation/update from perception. Always connect to a generating world state.DesireProcess: Generates desires from existing beliefs. Preserves the motivational chain.IntentionProcess: Commits to selected desires as actionable intentions.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bdi-mental-states is a skill published in the GitHub repository fabioc-aloha/Alex_Skill_Mall (4 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 4,052 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to bdi-mental-states, differing in 8 lines, and is treated as a copy.
Other skills, from other repositories
apply-change-leadership
Use when a manager's team is experiencing a significant organizational change — restructuring, strategy shift, leadership change, layoffs, or major process transition — and needs leadership that maintains team stability, preserves trust, and converts uncertainty into direction.
apply-cross-functional-leadership
Use when a manager needs to lead a project or initiative that depends on team members or stakeholders they do not formally manage — to build voluntary cooperation, alignment, and momentum across organizational boundaries through influence rather than authority.
apply-grow-coaching
Use when a manager wants to help a direct report solve a problem, develop a skill, or reach a goal through structured questioning rather than advice-giving — because telling people answers builds dependency while coaching builds self-sufficiency.
apply-upward-influence
Use when a manager needs to build an effective working relationship with their own manager, secure resources or decisions for their team, or influence organizational priorities without formal authority over the outcome.
build-psychological-safety
Use when a team leader wants to assess and improve the degree to which team members feel safe to speak up, admit mistakes, ask questions, and disagree — because psychological safety is the strongest predictor of team learning and high performance.
run-performance-improvement-plan
Use when a direct report has a documented pattern of performance falling below role expectations — after informal feedback has not produced sustained change — to create a structured, time-bound plan with clear success criteria before making a continuation decision.
