From 1a0f6bc20a89bc3bb2b93181ba02b4838127f560 Mon Sep 17 00:00:00 2001 From: Fernando de Oliveira <5161098+fedeoliv@users.noreply.github.com> Date: Thu, 14 May 2026 15:06:48 -0400 Subject: [PATCH] feat(governance): add agent intent governance (ADR 0014) Selectively adopts vocabulary and discipline from 'The Architecture of Intent' by Marcel Aldecoa to close three structural gaps: - Framework agents had no explicit behavioral envelope; coordinator agents now declare ## Behavioral Constraints (rules tools cannot enforce) and ## Composition (cross-component invariants). - Consumer specs describing AI capabilities had no canonical fragment for operational cost commitments; the feature template now carries a gated ## AI Cost Posture block (model tier, latency budget, prompt stability, per-call cost ceiling, cost-incident escalation), opted into via 'Describes AI capability: yes' in the Executive Summary. - The failure-diagnosis surface had no taxonomy mapping a failure to the upstream artifact that owns the fix; debugging-recovery now ships a three-category upstream-artifact principle (failure (spec), failure (validation), failure (agent)). Spec evolution log added to feature and migration spec templates with the three failure trigger values. Docs site gains a new concept page (AI Capability Specs), two new sections in Spec Amendment, and five glossary entries. ADR 0014 records the decision, options considered, and the AoI constructs deliberately not adopted (custom frontmatter scalars, Reversibility tier, Pattern A/B/C/D/E taxonomy, seven-category failure taxonomy, standalone authoring handbook, signal metrics, phase rename). AoI attribution added to ACKNOWLEDGMENTS under Articles and Blog Posts. CHANGELOG entry filed under [Unreleased]; manifest versions unchanged (release bump deferred to release commit).

Coordinator agents that own a side-effect surface must declare their behavioral envelope. Consumer specs that embed AI behavior must have a canonical block for operational cost commitments. +3. **Avoid ceremony for non-agent specs**. Most consumer features are product features, not AI capabilities. Forcing AI-specific structure on every spec would generate noise and erode adoption. +4. **Keep changes additive and non-breaking**. Existing specs, ADRs, agents, and consumer repos must remain valid after the change. No mandatory migration scripts. +5. **Make failures diagnosable by upstream artifact**. When an agent misbehaves, the upstream artifact that owns the fix must be identifiable from the failure category, so corrections compound structurally rather than as prompt patches. + +## Options Considered + +### Option 1: Full AoI adoption (replace template, rename phases, add signal metrics) + +Adopt the canonical 12-section AoI spec template wholesale. Rename Envision, Specify, Plan, Decompose, Implement, Review to Frame, Specify, Delegate, Validate, Evolve. Introduce the four AoI signal metrics (spec-gap rate, first-pass validation, cost per correct outcome, oversight load) with telemetry infrastructure to collect them. + +**Evaluation against priorities**: + +* **Preserve SDD spine**: Fails. Phase rename breaks agent IDs, marketplace manifest, instructions, consumer documentation, and the muscle memory of every adopting team. +* **Close governance gap**: Meets. The 12-section template covers it. +* **Avoid ceremony for non-agent specs**: Fails. AoI's template is built for agent systems; forcing every feature spec through 12 sections including Archetype Declaration adds significant overhead for product-feature specs that do not need it. +* **Additive and non-breaking**: Fails. Wholesale replacement is breaking by definition. +* **Failures diagnosable by upstream artifact**: Meets. AoI's failure taxonomy ships with the framework. + +### Option 2: Selective adoption (gated AI block on feature specs, behavioral envelope on agents, upstream-artifact taxonomy) + +Adopted. Four targeted constructs layered onto the existing framework: + +1. `## Behavioral Constraints` body section on user-facing agents (5 coordinators plus `specify` and `decompose`). Captures rules the runtime `tools:` array cannot enforce (e.g., "never APPROVE on a PR", "never commits to integration branch"). Worker sub-agents carry no manifest; they inherit their envelope from their parent's composition declaration and their own `description:` frontmatter. +2. Spec Evolution Log section in feature and migration spec templates, plus a gated `AI Cost Posture` block in the feature template (model-tier commitment, latency budget, prompt-stability invariant, per-call cost ceiling, cost-incident escalation). The block is gated by `Describes AI capability: yes/no`; when `no`, the block is omitted and the template is unchanged in size for the reader. Behavioral constraints on AI-capability specs use the general `Invariants` section; composition uses the general `Requirements` and `User Scenarios` sections. +3. `## Composition` body section on 4 coordinator agents (`devsquad.implement`, `devsquad.plan`, `devsquad.review`, `devsquad.refine`). Declares load-bearing cross-component invariants between the coordinator and its typed sub-agents. The runtime surfaces each sub-agent's `description:` at invocation time, so the section does not re-list sub-agents. +4. Three-category upstream-artifact failure taxonomy (`failure (spec)`, `failure (validation)`, `failure (agent)`) in `debugging-recovery`, with one worked example showing the spec-vs-validation distinction. Each category maps to one upstream artifact that owns the fix. `quality-gate` consults the same three categories when recording failure-driven amendments in the Spec Evolution Log trigger column. + +**Evaluation against priorities**: + +* **Preserve SDD spine**: Meets. No phase rename, no agent ID change, no breaking removal. +* **Close governance gap**: Meets. Coordinator agents that own the side-effect surface declare their behavioral envelope. Consumer specs that embed AI behavior have a canonical AI Cost Posture block. +* **Avoid ceremony for non-agent specs**: Meets. The gate keeps non-AI specs unchanged in shape. The only universal addition is the Spec Evolution Log (small, replaces the implicit Status plus Version pair). +* **Additive and non-breaking**: Meets. All additions are optional or gated. Existing specs remain valid. +* **Failures diagnosable by upstream artifact**: Meets. The three-category taxonomy ships as a reference file in `debugging-recovery` and is referenced by `quality-gate`. + +**AoI constructs considered and not adopted in this option**: + +* Custom frontmatter scalars on agents (`archetype`, `agency_level`, `autonomy`, `responsibility`, `reversibility`, `oversight_model`). The GitHub Copilot runtime does not consume custom frontmatter keys; the scalars would be inert documentation competing for credibility with the operational fields the runtime reads (`name`, `description`, `tools`, `agents`, `handoffs`, `model`). The behavioral envelope ships in body sections instead. +* Reversibility tier (R1-R4) on spec templates. The migration template's existing `Rollback Plan` section captures rollback semantics directly (maximum rollback time, state compatibility). Feature specs use the existing `Compatibility and Transition` section for the same concern. A categorical tier on top of these is taxonomy without behavioral effect. +* AoI Pattern A/B/C/D/E composition taxonomy. The labels carry no behavioral effect; the cross-component invariants in the `## Composition` section carry the actual contract. The labels are AoI vocabulary that ages with the source material rather than the framework's behavior. +* Seven-category failure taxonomy. Multiple AoI categories (Spec Gap, Spec Ambiguity, Scope Expansion) share one upstream artifact (`spec.md`); the finer granularity did not change what the framework does in response. The collapse to three categories preserves the diagnostic discipline without the vocabulary surface area. +* A standalone `agent-conventions.md` distributed handbook. Plugin authors learn from existing agents in the repo's `agents/` directory and from the inline structure of the agent files themselves; a separate handbook duplicates the runtime contract and creates documentation drift. +* AoI signal metrics, running scenarios, phase rename. Out of scope per priority 1 (preserve SDD spine). + +### Option 3: Status quo (no AoI adoption) + +Leave the framework as is. Document the AoI vocabulary in an internal reference but make no template, agent, or skill changes. + +**Evaluation against priorities**: + +* **Preserve SDD spine**: Meets trivially. +* **Close governance gap**: Fails. Both gaps persist. Agent files remain opaque about their authority, and consumer agent specs continue to be ad hoc. +* **Avoid ceremony for non-agent specs**: Meets trivially. +* **Additive and non-breaking**: Meets trivially. +* **Failures diagnosable by upstream artifact**: Fails. The upstream-artifact taxonomy gap persists. Corrections continue to accumulate in prompts. + +## Decision + +Adopt Option 2 (Selective adoption). + +Rationale, tied to the ranked priorities: + +* Option 2 is the only option that meets priorities 1, 2, 3, 4, and 5 simultaneously. Option 1 sacrifices priorities 1, 3, 4 for marginal gains on priorities 2 and 5 that Option 2 already delivers. Option 3 sacrifices priorities 2 and 5 entirely. +* The framework's strongest property is that it is small and opinionated. Option 2 preserves that property by gating new structure behind a single declaration (`Describes AI capability: yes/no`) and keeping the new agent body sections optional-by-position but present where the agent governs delegated work. +* Self-application is the most defensible adoption. The framework's own agents are exactly the delegated executors AoI is built to govern. The agent governance work and the composition declarations on coordinator agents are the highest-leverage moves available without changing what the framework looks like to a consumer who is not building agent capabilities. + +The implementation lands in the framework `CHANGELOG.md` under the next release entry. This ADR is the structural commitment; the CHANGELOG entry is the catalogue of what shipped. + +## Implementation Notes + +1. All template changes carry the standard provenance header (``) and require a version bump in both `plugin.json` copies plus a `CHANGELOG.md` entry. +2. The four copy-source templates (`docs/features/TEMPLATE.md`, `docs/migrations/TEMPLATE.md`, `docs/envisioning/TEMPLATE.md`, `docs/architecture/decisions/ADR-TEMPLATE.md`) continue to carry no inline provenance header. The manifest lock remains their sole provenance source. +3. The four constructs in the Decision are independently reviewable. The order between them is enforced by content (body sections must exist before `quality-gate` can enforce them; failure taxonomy must reference agent body fields), not by ADR. +4. The four AoI signal metrics, the running scenarios, the pattern catalog, and the phase rename remain out of scope. + +## References + +* "The Architecture of Intent" by Marcel Aldecoa, documentation site at `https://marcelaldecoa.github.io/TheArchitectureOfIntent/` diff --git a/docs/src/content/docs/concepts/ai-capability-specs.mdx b/docs/src/content/docs/concepts/ai-capability-specs.mdx new file mode 100644 index 0000000..181b026 --- /dev/null +++ b/docs/src/content/docs/concepts/ai-capability-specs.mdx @@ -0,0 +1,123 @@ +--- +title: AI Capability Specs +description: How to write a feature spec that describes an AI agent capability, including the gated AI Cost Posture block with model-tier, latency, prompt-stability, cost-ceiling, and escalation commitments. +banner: + content: | + This project is under active development and subject to breaking changes.

Authors who answer `no` see no AI-specific structure for the rest of the document. + +## The AI Cost Posture Block + +When the gate is `yes`, the spec must populate five fields. The fields commit the feature to operational characteristics that downstream operators measure and that future amendments must honor. + +### Model-tier commitment + +Which model tier the feature commits to, per AI step where multiple steps exist. + + + + Highest reasoning capability, slow, expensive per call. Use for multi-step planning, complex synthesis, hard refactoring. + + + State-of-the-art general capability, balanced speed and cost. Use for tool-heavy agents, code generation, conversational UX. + + + Capable but cheaper and faster than frontier. Use for routine summarization, classification with context, RAG. + + + Small, fast, cheap, limited reasoning depth. Use for high-volume classification, simple extraction, latency-critical UX. + + + +A spec with multiple AI steps commits a tier per step with a one-line rationale. The tier is the durable commitment; the specific model is chosen at implementation time and may change as the platform's lineup shifts. + +### Latency budget + +Three percentile values plus a behavior on breach: + +- `p50`, `p95`, `p99` latency targets. +- Behavior on breach: `degrade` (skip an optional step), `alert` (notify operators), or `halt` (refuse to serve). + +The budget is what the operator measures the implementation against. A breach is a signal that either the implementation drifted or the spec under-committed. + +### Prompt-stability invariant + +Which prompt elements are guaranteed stable across runs to support caching, and what would break the invariant. A typical statement: "the system message and tool schema are fixed across calls within a 24-hour window. A tool-schema change triggers a spec amendment." + +The invariant matters for two reasons: prompt caches are a major cost lever, and a silent prompt change is one of the easiest ways for an AI capability to drift away from its spec without anyone noticing. + +### Per-call cost ceiling + +A hard cap in tokens or dollars per call, plus a behavior on breach: `escalate` (route to human), `halt` (refuse to serve), or `degrade` (fall back to a cheaper path). + +The ceiling is the financial guarantee. A call that exceeds it is a cost incident, not a normal cost variation. + +### Cost-incident escalation + +What cost-side condition triggers a stop or human-review gate. Typical example: "any 1-hour window where 5% of calls exceed the per-call ceiling triggers a stop and post-mortem." + +This is the trip wire. The other four fields establish a budget; this one names what trips a human-in-the-loop intervention. + +## When the Platform Picks the Model + +The five fields presuppose that the spec author operates the AI service: chooses the model, pays per token, monitors latency. That fits one common scenario (a team building an AI product on top of OpenAI, Anthropic, Azure OpenAI, or similar). + +The other common scenario is a team consuming a managed AI platform where the runtime picks the model: a hosted developer assistant, an embedded AI feature in another product, or any surface where model selection is governed by the platform rather than the spec. + +For runtime-managed scenarios, set each field to `N/A - model chosen by runtime` and add one line per field naming what runtime governs the choice. A worked example: + +```text +- Model-tier commitment: N/A - model chosen by runtime + ([platform name] picks per user plan and platform selection logic) +- Latency budget: N/A - governed by the runtime platform +- Prompt-stability invariant: agent body and tool list are versioned in + this repo; changes trigger a CHANGELOG entry +- Per-call cost ceiling: N/A - billed via the runtime platform plan +- Cost-incident escalation: N/A - cost governed by the runtime platform plan +``` + +The block still serves as a forcing function: it asks whether the team has thought about what they are committing to operationally. If the honest answer is "nothing, the platform picks", that answer is the commitment. + +## What Does Not Go in This Block + +Three categories of content that AI-capability specs sometimes try to put in the AI Cost Posture block but that belong elsewhere in the feature template: + +| Content type | Where it goes instead | +|---|---| +| Behavioral constraints (rules the agent must honor even when tools permit otherwise) | The general `## Invariants` section.
