Agent skills, tools, prompts, and traces

This page answers which method skill an agent may load, which data tools it may call, where its focused prompt lives, and which deterministic trace proves what actually ran.

Skill guidance is method, never evidence. Search is a tool, not a skill. Memory Bank is advisory context, never authority.

Runtime inventory

Agent	ADK name and model	Typed contract	Filesystem skill	Separate tools and research
Nimi	`nimi_analyst`, `gemini-3.5-flash`	`AnalystInput` → `SourceAnalysis`	`nimi-analysis-skills` (seven references)	Isolated `nimi_google_search_agent`; optional isolated `nimi_agent_search_agent` for configured Vertex AI Search
Ryan	`ryan_strategist`, `gemini-3.5-flash`	`StrategistInput` → `StrategistResult` / `ContentStrategy`	`ryan-strategy-skills` (seven references)	Isolated, request-bound `ryan_google_search_agent` only when current public information is necessary
Temi	`temi_editorial_planner`, `gemini-3.5-flash-lite`	`EditorialPlannerInput` → `EditorialPlan`	`temi-editorial-planning-skills` (six references)	Six read-only views over one immutable, digest-bound planning snapshot; no search or core MCP server
Noni	`noni_copywriter`, `gemini-3.5-flash`	`CopywriterInput` → `ContentDraft`	`noni-writing-skills` (eleven references)	`search_verified_publications`; native Google Search through isolated `google_search_agent`
Dara	`dara_editor`, `gemini-3.5-flash`	`EditorialReviewInput` → `EditorialAssessment`	`dara-editing-skills` (seven references)	Skill loaders only; no data or research tool
Maya	`maya_presenter`, `gemini-3.5-flash`	`UiContext` → `SurfacePlan`	None	None; deterministic host hydration only
Nova	`nova_liaison`, `gemini-3.5-flash`	`LiaisonInput` → `LiaisonAnswer`	`trend-scan`, `signal-watch`, `engagement-insights`, `posting-schedule`, or `job-status`	Six bounded reads for trends, engagement, operator feed, job status, and posting windows

Prompt and runtime locations

Agent	Focused prompt	Skill or tool runtime	Trace enforcement
Nimi	`agent/harmonia_agent/nimi_prompt.py`	`nimi_skills.py`, `nimi_research.py`	Independent request-bound skill and research traces
Ryan	`agent/harmonia_agent/ryan_prompt.py`	`ryan_skills.py`	Skill-first trace and optional isolated-search trace
Temi	`agent/harmonia_agent/temi_prompt.py`	`temi_skills.py`	Skill-first trace plus exact snapshot identity and digest
Noni	`agent/harmonia_agent/noni_prompt.py`	`noni_skills.py`	Skill-first trace plus exact brief-bound research evidence
Dara	`agent/harmonia_agent/dara_prompt.py`	`dara_skills.py`	Skill-first trace with allow-listed resource paths
Maya	`agent/harmonia_agent/maya_prompt.py`	`a2ui_presenter.py`	Closed entity-catalog and component/reference validation
Nova	`agent/harmonia_agent/nova_prompt.py`	`nova_liaison.py`, `skills_runtime.py`	One skill precedes compatible reads; claims cite returned evidence IDs

Loading and grounding rules

Nimi, Ryan, Temi, Noni, and Dara load their named project-owned skill exactly once, then load only approved references relevant to the request. Missing, duplicate, out-of-order, irrelevant, or unapproved resource loads fail closed. Nova selects exactly one routing skill before a compatible read tool. Maya has no skill or tool trace. Search-capable agents never place native google_search beside filesystem or function tools in the same model request. A dedicated ADK search agent returns a typed, request-bound result. Deterministic code preserves and validates grounding chunks, supports, queries, titles, URLs, and search entry-point metadata before search evidence IDs may be cited.

Evidence and authority

Valid evidence comes only from the typed invocation: operator context IDs, Nimi moment or angle IDs, verified performance IDs, eligible Memory Bank fact IDs with Firestore provenance, approved internal read-tool evidence IDs, or validated native-search evidence IDs. Skill files, prompts, model memory, and source-coverage ledgers cannot prove customer, market, trend, performance, or source claims. No agent may approve, transition workflow state, schedule an external effect, publish, access credentials, create receipts, verify effects, or grant policy exceptions. See the authority matrix and agent contracts.
