agentfootprint — The Explainable Agent Framework
agentfootprint structures AI agents as composable flowcharts, so every injection, read, write, decision and tool call becomes connected evidence as the run happens. Every concept takes an LLMProvider — swap mock({...}) for anthropic({...}) with zero code changes.
Core principles:
- Adapter-swap testing ($0 test runs, deterministic assertions)
- The ladder:
mock→ollama(free, local, real model) → a paid provider - Declare context (facts, steering, skills); the framework decides WHEN it fires and WHICH slot it lands in
- Collect during traversal, never post-process (inherited from footprintjs)
npm install agentfootprint footprintjs
Read this first — what does NOT exist
These are not hypothetical. A capable author, working from a correct mental model of this library, invented all four in one document. Treat them as the things you are most likely to get wrong here.
| You will reach for | The reality |
|---|---|
startRun(...) | No such function. The door is agent.run(input, options?), where AgentInput = { message: string; identity?; continueFrom? } and AgentOutput = string. run() returns AgentOutput | RunnerPauseOutcome — a run paused for a human returns a checkpoint; discriminate with isPaused(result). |
RunStep as skill/route history | RunStep is real and it is something else — the footprintjs flowchart TOPOLOGY slider, exported from agentfootprint/observe. Its kind is 'sequential' | 'fork' | 'merge' | 'decide' | 'iteration' | 'iteration-exit' | 'react'. Nothing in it concerns skills. Importing it succeeds, which is exactly why it is dangerous. For route history use routeRecorder() from the same door. |
| the LLM classifier as routing "tier 3" | It is a tier-2 strategy. Tier 1 = declared start rules. Tier 2 = the configured scorer — llmClassifier(provider) OR keywordScorer() OR embeddingScorer(e) OR the entry scorer; near-ties fall through rather than argmax. Tier 3 = a menu the model resolves in-band through read_skill's own description, reached only when tier 2 was NOT decisive. |
| a skill's tools being gated to that skill automatically | They are not, by default. defineSkill({ tools }) puts them in the agent's static tool list at build time — visible from iteration 1 whether the skill ever activates or not. Ask for the gate: .toolsFromActiveSkill() (agent-wide), skillGraph({ scopeTools: true }) (graph-wide), or autoActivate: 'currentSkill' (per skill). .tree() leaves are the one shape scoped by default. |
Two more absences: there is no runtime force-stop governor (routeRecorder().getTrips()
only labels a spinning run; maxIterations is the hard stop), and there is no
automatic re-delivery of an ageing skill body (refreshPolicy is stored and never
read on any version — use surfaceMode: 'both').
Subpath map — 13 doors
agentfootprint (main barrel: Agent, LLMCall, defineTool, control flow, patterns, defineRAG, pause/resume) · /providers (mock, anthropic, openai, bedrock, ollama, mcpClient, embedders — every provider, so bundlers never walk the vendor SDKs from the main barrel) · /context (defineSkill, defineFact, defineSteering, defineInstruction, skillGraph, skillsFromDir, the scorers) · /memory (defineMemory, InMemoryStore, mockEmbedder, the stores) · /rag (stores + loaders; defineRAG itself is on the main barrel) · /observe (recorders, tracing, RunStep) · /resilience (provider decorators) · /reliability (the rules-based fail-fast gate) · /cache (prefix-cache strategies; importing it registers them) · /security · /hosting · /events · /skill-graph (the routing layer with no framework attached, for a host that is not this agent).
Core Concepts
LLMCall — a single LLM call, no tools
import { LLMCall } from 'agentfootprint';
import { mock } from 'agentfootprint/providers';
const caller = LLMCall.create({ provider: mock({ reply: 'Hello!' }), model: 'mock' }).system('You are helpful.').build();
const result = await caller.run({ message: 'Hi' });
Agent — a ReAct agent with tools
import { Agent, defineTool } from 'agentfootprint';
import { mock } from 'agentfootprint/providers';
const weather = defineTool({
name: 'weather',
description: 'Get current weather for a city.',
inputSchema: { type: 'object', properties: { city: { type: 'string' } }, required: ['city'] },
execute: async ({ city }: { city: string }) => `${city}: 72°F, sunny`,
});
const agent = Agent.create({ provider: mock({ reply: 'It is 72°F.' }), model: 'mock' })
.system('You answer weather questions using the weather tool.')
.tool(weather)
.maxIterations(5)
.build();
const result = await agent.run({ message: 'Weather in Paris?' });
Context — facts, steering, skills, and declared routing
import { defineFact, defineSteering, defineSkill, skillGraph } from 'agentfootprint/context';
Agent.create({ provider, model })
.fact(defineFact({ id: 'user-profile', data: 'Plan: Pro · Customer since 2022' }))
.steering(defineSteering({ id: 'policy', prompt: 'Never promise a refund before checking.' }))
.skill(defineSkill({ id: 'refunds', description: 'Refund procedure.', body: '…', tools: [issueRefund] }))
.build();
defineSkill bodies load on demand — the model opens one with read_skill, or a skillGraph() routes to it:
const graph = skillGraph()
.entry(triage, { when: (c) => /order/.test(c.userMessage) }) // where the turn STARTS
.route(triage, refunds, { onToolReturn: 'lookup_order' }) // a declared handoff
.build();
Agent.create({ provider, model }).skillGraph(graph).build();
graph.toMermaid(); // declared === drawn
.entry() and .route() take the skill OBJECTS, not their ids. The object form is
the other door — skillGraph({ skills, start, steps }) returns a finished graph with
nothing to chain.
A skill is active exactly while the cursor is on it — one skill's turn at a time. An .entry(x) with no when is the persistent base (always), on beside whatever the cursor is on.
The cursor is a program counter, not a per-turn classifier. Nine causes move it (or
decline to), reported as cursorMove.by on agentfootprint.context.evaluated and as
outcome on routeRecorder().getHops():
'entry' (cold start) · 'route' (a declared from-gated edge fired) · 'tool-proposal'
(a TOOL RESULT proposed a transition and the graph accepted it) · 'model-pick' (a
gate-accepted read_skill) · 'intent' (the tier-2 scorer was decisive) · 'continuity'
(the cursor inherited from the previous turn held) · 'decider' (an out-of-band menu
resolver) · 'stay' (nothing fired — sticky, and a recorded decision, not an absence) ·
'none' (no cursor at all: nothing to enter, or a tree(), which has no cursor).
routeRecorder's RouteOutcome is those eight minus 'none' (no cursor, no hop) plus
'rejected' — nine values. Precedence when several want it at once:
declared edge > accepted tool proposal > model pick > stay. A suppressed pick emits
agentfootprint.skill.reroute_superseded; a parallel batch matching different targets
emits agentfootprint.skill.route_conflict.
The cursor is per RUN by default. A second run() starts cold at the entry.
.skillGraph(graph, { continuity: 'conversation' }) makes it span the conversation.
read_skill has a three-way design, not one list. Per iteration a skill is
reachable (named under "Reachable from here"), refusable (named under "Not reachable
from here" — a graph refusal is about WHERE THE CURSOR IS, so naming it lets the model
route in one step), or hidden (absent entirely — a hidden skill is about WHO IS ASKING,
and naming it would leak the shape of somebody else's permissions; needs a
PermissionChecker governing skill_read). The enum stays the full catalog in every
case — narrowing it would turn a policy refusal into a generic schema error the model
never reads.
A refused pick gets one teaching sentence back and moves nothing:
read_skill("audit-log") is not reachable from here. Reachable skills: billing. Pick one of these, or finish.
The authority rule. A tool result is written into the conversation once and then only
ages; the system prompt is rebuilt from nothing every iteration (reactMode: 'dynamic',
the default, re-runs the InjectionEngine and all three slots). So standing instructions
belong in the recomposed surface. reactMode: 'classic' caches system-prompt and tools
after turn 1 — do not use it with skills.
RAG — retrieve, augment, generate
import { defineRAG } from 'agentfootprint'; // wiring lives on the main barrel
import { InMemoryStore, mockEmbedder } from 'agentfootprint/memory';
Agent.create({ provider, model })
.rag(defineRAG({ id: 'docs', store: new InMemoryStore(), embedder: mockEmbedder(), topK: 5 }))
.build();
Control flow + patterns — compose runners
import { Sequence, Parallel, Loop, Conditional, workflow, graph } from 'agentfootprint';
import { swarm, debate, reflection, selfConsistency, mapReduce, tot } from 'agentfootprint'; // patterns
const pipeline = Sequence.create().step('research', researchAgent).step('write', writerAgent).build();
const desk = swarm({
agents: [{ id: 'research', runner: researchAgent }, { id: 'write', runner: writerAgent }],
route: ({ message }) => (/write/.test(message) ? 'write' : 'research'),
});
Providers
import { mock, anthropic, openai, bedrock, ollama } from 'agentfootprint/providers';
const provider = process.env.NODE_ENV === 'production'
? anthropic({ apiKey: process.env.ANTHROPIC_API_KEY! })
: ollama('llama3.2'); // free local model; or mock({...}) for determinism
mock takes { reply } (one fixed answer), { replies: [...] } (consumed in order — exhaustion throws loud), or { respond: (req) => … } (build the answer from the request, including toolCalls).
Tools
import { defineTool } from 'agentfootprint';
const calculator = defineTool({
name: 'calculator', // `name`, not `id`
description: 'Perform arithmetic',
inputSchema: { type: 'object', properties: { expression: { type: 'string' } } },
execute: async ({ expression }: { expression: string }) => String(evaluate(expression)),
});
A long tool that says where it is
execute: async (args, ctx) => {
for (const [i, hop] of hops.entries()) {
await visit(hop);
ctx.progress({ done: i + 1, total: hops.length }); // → stream.tool_progress
}
return summarize(hops);
},
ctx.progress is always present, never throws, never blocks, and never reaches
the model — the framework stamps toolCallId / toolName / iteration, you own
payload. agent.on('agentfootprint.stream.*') and toSSE(agent) carry it with
no extra wiring.
When a tool finds nothing, and what a clean result does not cover
import { absent, coverage, defineTool } from 'agentfootprint';
// "I looked and there is nothing" — never readable as "I could not look".
execute: ({ port }) => rows.length ? rows : absent({
what: `FLOGI entries on ${port}`,
checked: ['shq-fab-a: the live fcns database', 'window: the last 24h'],
notChecked: [{ what: 'the archived history', why: 'older than the 24h window' }],
cannotCover: [{ what: 'the peer fabric', why: 'this collector is scoped to one fabric' }],

## Core Concepts
### LLMCall — a single LLM call, no tools
```typescript
import { LLMCall } from 'agentfootprint';
import { mock } from 'agentfootprint/providers';
const caller = LLMCall.create({ provider: mock({ reply: 'Hello!' }), model: 'mock' }).system('You are helpful.').build();
const result = await caller.run({ message: 'Hi' });
```
### Agent — a ReAct agent with tools
```typescript
import { Agent, defineTool } from 'agentfootprint';
import { mock } from 'agentfootprint/providers';
const weather = defineTool({
name: 'weather',
description: 'Get current weather for a city.',
inputSchema: { type: 'object', properties: { city: { type: 'string' } }, required: ['city'] },
execute: async ({ city }: { city: string }) => `${city}: 72°F, sunny`,
});
const agent = Agent.create({ provider: mock({ reply: 'It is 72°F.' }), model: 'mock' })
.system('You answer weather questions using the weather tool.')
.tool(weather)
.maxIterations(5)
.build();
const result = await agent.run({ message: 'Weather in Paris?' });
```
### Context — facts, steering, skills, and declared routing
```typescript
import { defineFact, defineSteering, defineSkill, skillGraph } from 'agentfootprint/context';
Agent.create({ provider, model })
.fact(defineFact({ id: 'user-profile', data: 'Plan: Pro · Customer since 2022' }))
.steering(defineSteering({ id: 'policy', prompt: 'Never promise a refund before checking.' }))
.skill(defineSkill({ id: 'refunds', description: 'Refund procedure.', body: '…', tools: [issueRefund] }))
.build();
```
`defineSkill` bodies load on demand — the model opens one with `read_skill`, or a `skillGraph()` routes to it:
```typescript
const graph = skillGraph()
.entry(triage, { when: (c) => /order/.test(c.userMessage) }) // where the turn STARTS
.route(triage, refunds, { onToolReturn: 'lookup_order' }) // a declared handoff
.build();
Agent.create({ provider, model }).skillGraph(graph).build();
graph.toMermaid(); // declared === drawn
```
`.entry()` and `.route()` take the skill OBJECTS, not their ids. The object form is
the other door — `skillGraph({ skills, start, steps })` returns a finished graph with
nothing to chain.
A skill is active exactly while the cursor is on it — one skill's turn at a time. An `.entry(x)` with **no** `when` is the persistent base (`always`), on beside whatever the cursor is on.
**The cursor is a program counter, not a per-turn classifier.** Nine causes move it (or
decline to), reported as `cursorMove.by` on `agentfootprint.context.evaluated` and as
`outcome` on `routeRecorder().getHops()`:
`'entry'` (cold start) · `'route'` (a declared `from`-gated edge fired) · `'tool-proposal'`
(a TOOL RESULT proposed a transition and the graph accepted it) · `'model-pick'` (a
gate-accepted `read_skill`) · `'intent'` (the tier-2 scorer was decisive) · `'continuity'`
(the cursor inherited from the previous turn held) · `'decider'` (an out-of-band menu
resolver) · `'stay'` (nothing fired — sticky, and a recorded decision, not an absence) ·
`'none'` (no cursor at all: nothing to enter, or a `tree()`, which has no cursor).
`routeRecorder`'s `RouteOutcome` is those eight minus `'none'` (no cursor, no hop) plus
`'rejected'` — nine values. Precedence when several want it at once:
**declared edge > accepted tool proposal > model pick > stay.** A suppressed pick emits
`agentfootprint.skill.reroute_superseded`; a parallel batch matching different targets
emits `agentfootprint.skill.route_conflict`.
**The cursor is per RUN by default.** A second `run()` starts cold at the entry.
`.skillGraph(graph, { continuity: 'conversation' })` makes it span the conversation.
**`read_skill` has a three-way design, not one list.** Per iteration a skill is
*reachable* (named under "Reachable from here"), *refusable* (named under "Not reachable
from here" — a graph refusal is about WHERE THE CURSOR IS, so naming it lets the model
route in one step), or *hidden* (absent entirely — a hidden skill is about WHO IS ASKING,
and naming it would leak the shape of somebody else's permissions; needs a
`PermissionChecker` governing `skill_read`). **The enum stays the full catalog in every
case** — narrowing it would turn a policy refusal into a generic schema error the model
never reads.
A refused pick gets one teaching sentence back and moves nothing:
```text
read_skill("audit-log") is not reachable from here. Reachable skills: billing. Pick one of these, or finish.
```
**The authority rule.** A tool result is written into the conversation once and then only
ages; the system prompt is rebuilt from nothing every iteration (`reactMode: 'dynamic'`,
the default, re-runs the InjectionEngine and all three slots). So standing instructions
belong in the recomposed surface. `reactMode: 'classic'` caches system-prompt and tools
after turn 1 — do **not** use it with skills.
### RAG — retrieve, augment, generate
```typescript
import { defineRAG } from 'agentfootprint'; // wiring lives on the main barrel
import { InMemoryStore, mockEmbedder } from 'agentfootprint/memory';
Agent.create({ provider, model })
.rag(defineRAG({ id: 'docs', store: new InMemoryStore(), embedder: mockEmbedder(), topK: 5 }))
.build();
```
### Control flow + patterns — compose runners
```typescript
import { Sequence, Parallel, Loop, Conditional, workflow, graph } from 'agentfootprint';
import { swarm, debate, reflection, selfConsistency, mapReduce, tot } from 'agentfootprint'; // patterns
const pipeline = Sequence.create().step('research', researchAgent).step('write', writerAgent).build();
const desk = swarm({
agents: [{ id: 'research', runner: researchAgent }, { id: 'write', runner: writerAgent }],
route: ({ message }) => (/write/.test(message) ? 'write' : 'research'),
});
```
## Providers
```typescript
import { mock, anthropic, openai, bedrock, ollama } from 'agentfootprint/providers';
const provider = process.env.NODE_ENV === 'production'
? anthropic({ apiKey: process.env.ANTHROPIC_API_KEY! })
: ollama('llama3.2'); // free local model; or mock({...}) for determinism
```
`mock` takes `{ reply }` (one fixed answer), `{ replies: [...] }` (consumed in order — exhaustion throws loud), or `{ respond: (req) => … }` (build the answer from the request, including `toolCalls`).
## Tools
```typescript
import { defineTool } from 'agentfootprint';
const calculator = defineTool({
name: 'calculator', // `name`, not `id`
description: 'Perform arithmetic',
inputSchema: { type: 'object', properties: { expression: { type: 'string' } } },
execute: async ({ expression }: { expression: string }) => String(evaluate(expression)),
});
```
### A long tool that says where it is
```typescript
execute: async (args, ctx) => {
for (const [i, hop] of hops.entries()) {
await visit(hop);
ctx.progress({ done: i + 1, total: hops.length }); // → stream.tool_progress
}
return summarize(hops);
},
```
`ctx.progress` is always present, never throws, never blocks, and never reaches
the model — the framework stamps `toolCallId` / `toolName` / `iteration`, you own
`payload`. `agent.on('agentfootprint.stream.*')` and `toSSE(agent)` carry it with
no extra wiring.
### When a tool finds nothing, and what a clean result does not cover
```typescript
import { absent, coverage, defineTool } from 'agentfootprint';
// "I looked and there is nothing" — never readable as "I could not look".
execute: ({ port }) => rows.length ? rows : absent({
what: `FLOGI entries on ${port}`,
checked: ['shq-fab-a: the live fcns database', 'window: the last 24h'],
notChecked: [{ what: 'the archived history', why: 'older than the 24h window' }],
cannotCover: [{ what: 'the peer fabric', why: 'this collector is scoped to one fabric' }],

Skill purpose: Use when building AI agents with agentfootprint — LLMCall, Agent, skills, RAG, memory, control flow, Swarm concepts, mock/anthropic/openai/ollama providers, tools, recorders, resilience, and streaming. Also use when someone asks how agentfootprint works or wants to understand the framework.
