CONTEXT IS FINITE AND FRAGILE. Tokens compete for attention. + Tokens far from current focus degrade in influence on inference + (attention decay over distance). Decompose work to keep critical + instructions near the focus point. Corollary: any state that must + survive long sessions, multi-step execution, or thread spawns + MUST live OUTSIDE the context window (a plan file, a structured + store, a checkpoint) and be reloaded at re-grounding boundaries. + Plans live on disk, not in memory. + +2. CONTEXT MUST BE EXPLICIT. Threads are stateless across spawns. + Anything not loaded as text into a thread does not exist for that + thread. Hand off via explicit artifacts, not assumed memory. + +3. OUTPUT IS PROBABILISTIC. Determinism comes from constraints, + structure, grounding. Reduce variance with: scope reduction, + validation gates, deterministic tools as truth anchors. + +4. COMPOSITION IS FIRST-CLASS. A primitive is not a leaf file; it + may itself be a MODULE -- a unit of distribution with its own + declared dependencies. Designs MUST treat the module graph + (depend vs duplicate; inline vs sibling vs external; pinning; + distribution boundary) as part of the architecture, not a + packaging afterthought. + +5. PLAN BEFORE EXECUTION. Decision and execution are separate + activities and SHOULD live in separate context regions. Any + non-trivial work (multi-step, multi-file, or spawn-bound) + produces a PLAN ARTIFACT before any module body is drafted. + The plan persists to a runtime-provided store (file, structured + store, or both) so the executor can reground itself instead of + relying on degraded recall. The handoff packet IS the plan. + +## Disambiguation you enforce in every review + +PERSONA SCOPING: a stored markdown file loaded as text into a thread +to bias inference (a "lens"). It has no execution life of its own. + +SUBAGENT (or THREAD): a runtime-spawned child execution unit with +its OWN fresh context window. Returns a value to the parent. + +These are orthogonal. A thread MAY load any persona at startup. A +persona is NOT a thread. Conflating them is the central error in +this domain. Flag it in every review where it appears. + +PRIMITIVE: a file the runtime loads (skill, persona, rule, +orchestrator workflow). The unit of REASONING. + +MODULE: a unit of DISTRIBUTION (one or more primitives + declared +dependencies + version + identity). One primitive may itself be a +module. Conflating primitive with module hides composition: leaf +files get duplicated across projects instead of depended on as +modules.

PERSONA SCOPING FILE + +A markdown file (with frontmatter) loaded as text into a thread at +the start of execution to bias inference toward a specific lens or +role. It does NOT execute. It does NOT spawn anything. It is a +prompt-shaped knowledge artifact. + +Substrate fields (every harness offers these or equivalents): +- a unique `name` +- a `description` (plain text the harness shows to the user / model) +- the body: instructions, principles, anti-patterns + +Substrate behavior: +- Loaded by the harness when explicitly invoked or composed. +- Shapes the lens; does not gate tool access (that is the rule + file's job in some harnesses, or part of the persona body in + others). + +### 2. MODULE ENTRYPOINT (SKILL) + +A directory containing a markdown entrypoint file plus an `assets/` +subtree. The entrypoint is loaded into the thread when the harness +matches the module's activation criteria (description-driven +selection, explicit invocation, or both). Assets load lazily on +demand from inside the entrypoint. + +Industry standard: agentskills.io defines the SKILL.md + +description-driven activation contract that every modern harness +implements (sometimes with renames or additional fields). + +Substrate fields: +- `name` +- `description` (used for activation matching) +- the body: the entrypoint procedure +- `assets/`: arbitrary files (markdown, scripts, images) the + entrypoint may load at specific steps + +Substrate behavior: +- The harness selects which skills to make available based on the + description matching the user task. +- Once activated, the SKILL.md body loads into the thread; the + thread reads it and follows its procedure, loading assets only + at the steps that need them. + +### 3. SCOPE-ATTACHED RULE FILE + +A markdown file whose content the harness automatically loads into +any thread whose work matches a declared scope. Scope is typically +a glob pattern over file paths or a context predicate. + +Substrate fields: +- a scope predicate (glob, path, or other classifier) +- the body: rules, conventions, hard constraints + +Substrate behavior: +- Loaded automatically by the harness when the thread's work + matches the scope. +- The thread does not have to know the rule file exists. + +### 4. CHILD-THREAD SPAWN + +A built-in capability of any modern agent harness: the running +thread can spawn a CHILD THREAD with its own fresh context window, +optionally seeded with a persona and a task description. The child +returns a value (its final response or a structured result). The +parent is suspended at the spawn site until the child returns +(unless the harness offers async spawn). + +Substrate semantics: +- Child has NO access to parent's context except what the parent + passes as the task description. +- Child MAY load its own personas, skills, rules. +- Parent receives the child's return value as text (or structured + data, harness-dependent). +- Multiple spawns from the same parent run in parallel where the + harness supports it. + +### 5. TRIGGER ORCHESTRATOR + +A scheduled or event-triggered configuration that spawns a session +in response to an external event (timer, repository event, webhook, +user invocation). Lives outside any single session; it is the entry +point that creates sessions in the first place. + +Substrate fields: +- a trigger declaration (event, schedule, or interactive) +- a session bootstrap (initial task, initial persona / skill set) +- output channel (where the session's results go) + +Substrate behavior: +- Each trigger creates a NEW session. Sessions are stateless across + triggers unless persistence is engineered explicitly (pattern + P6 in architecture-patterns.md). + +### 6. PLAN PERSISTENCE + +Underlying property: ATTENTION DEGRADATION. Tokens far from the +current focus point exert weaker influence on inference. As a +session grows, earlier decisions, todos, and constraints fade from +the model's effective recall even though they remain technically +in-context. + +Coping mechanism every modern harness now exposes: a runtime store +where the thread persists its plan and progress, then re-reads the +store at re-grounding boundaries (new step, new file, new spawn). + +Substrate fields (every harness offers these or equivalents): +- a PLAN ARTIFACT slot (free-form, typically markdown) capturing + the problem statement, approach, and step list +- a TODO/STATUS slot (structured, queryable) for per-step status + with optional dependencies between items +- (optional) a CHECKPOINT slot for milestone snapshots +- (optional) a FILES slot for cross-step artifacts that must + outlive any single step's context + +Substrate behavior: +- The thread WRITES the plan once, EARLY (before drafting modules + or spawning workers). +- The thread READS the plan again at re-grounding boundaries: + start of each step, return from a spawn, after a tool failure, + or whenever uncertainty rises. +- Spawned child threads receive a POINTER to the relevant slice + of the plan (or a copy of it) in their task description; they + do not inherit the parent's context. +- The store survives the context window by definition; it is + the explicit cure for ATTENTION DEGRADATION. + +When to use: +- Work spans more than ~3 dependent steps. +- Work spans more than one file. +- Work will spawn one or more child threads that must coordinate. +- Session is expected to be long enough that early constraints + risk decay. + +Skip when: +- Single-shot one-step work where the entire instruction set fits + comfortably in the prompt and no spawn is involved. + +## Substrate invariants + +These hold across every supported harness: + +- Personas, skills, and rules are TEXT loaded into context. They + do not execute. They steer inference. +- The thread executes; it spawns; it returns. +- A child thread is the only mechanism for parallelism and + context isolation. +- No primitive can mutate another primitive's content at runtime. +- Tokens cost attention. Smaller substrates yield sharper + inference. +- Attention decays with distance from the focus point. State that + must survive that decay belongs in a persistence slot, not in + the prompt. + +## What the substrate deliberately does NOT cover + +The following vary per harness and live ONLY in per-harness +adapter files: + +- The actual file extension and folder path for each primitive. +- The exact frontmatter field names (e.g. trigger field syntax). +- The name of the spawn primitive (a tool name, an SDK call, etc.). +- The name of any harness-specific tool that primitives commonly + use (file ops, web fetch, shell). +- The mechanism for declaring multi-target compatibility (some + harnesses use a magic folder; others use a config file). +- The exact plan-persistence layout (file path, in-context list, + embedded SQL, checkpoints folder, etc.). Substrate guarantees + the SLOTS exist; per-harness adapters name the syntax. + +A primitive that stays within this substrate is portable across +all harnesses APM supports.
