Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

artifact-conventions 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Runtime primer: AGENTS.md §Artifact Conventions. This file is the expanded canonical reference for rationale, exceptions, and remediation details; it is not a required read for ordinary workflow execution. scripts/drift-report.mjs --strict checks parity for the runtime-critical contract.

Artifact Convention Rules

These rules apply whenever an agent reads or modifies files inside a Feature Workspace at specs/<feature-folder>/. The ADR preservation rules in this file also apply to standalone ADRs under specs/adrs/. They protect the integrity of cross-referenced identifiers, gating state, and structural conventions that downstream phases depend on. They do not apply to other Project Context Specs such as specs/prd.md, specs/sad.md, specs/dod.md, specs/project-plan.md, or epic detail files under specs/plan/.

Preservation Rules

These are non-negotiable guardrails — violating them breaks cross-artifact traceability and phase gating.

Rule Rationale
Do NOT reorder product user story priorities or non-product objective priorities (P1, P2, P3) without explicit user approval Priority order drives task phasing and MVP scope — reordering silently changes what ships first
Do NOT change task IDs (T001, T002…) Task IDs are cross-referenced in coverage maps, dependency graphs, and issue trackers
Do NOT change checklist IDs (CHK001, CHK002…) Checklist IDs are referenced externally by quality-assurance checks and test evaluators
Preserve checkbox state (- [ ] vs - [X]) Checkbox state is a gating signal — flipping it can unblock or block downstream phases
Do NOT change requirement IDs (FR-001, TR-001, OR-001, RR-001) Requirement IDs are mapped to tasks, coverage reports, and compliance checks
Do NOT change success criteria IDs (SC-001, SC-002…) Success criteria IDs are referenced in phase reviews and validation
Do NOT change architecture decision IDs (AD-001, AD-002…) Architecture decision IDs may be referenced by tasks and implementation agents
Do NOT rename, renumber, or delete standalone ADR files under specs/adrs/ ADR file paths are stable references; ADR-NNNN numbers are monotonic, never reused, and cross-referenced by project-plan epics, plan traceability tags {SAD:ADR-NNNN}, and sad.md catalog rows
Do NOT write standalone ADR files outside the ADR Author subagent All ADR file mutations must flow through .github/agents/_adr-author.md per the MADR authoring contract
Do NOT change stress-test finding IDs (STF-001, STF-002…) Stress-test finding IDs are referenced by [NEEDS CLARIFICATION: STF-###] markers and adversarial analysis reports
[VERIFY: <command>] command text is NOT a cross-referenced ID — it may be edited/corrected to reflect the real check Unlike T###/FR-###/AD-### IDs, VERIFY command text is an executable assertion, not a stable reference; updating a broken command (wrong path, stale flag) is a normal maintenance edit, not an ID violation
Respect [NEEDS CLARIFICATION] markers — only resolve with user-approved answers Silently removing a marker hides unresolved ambiguity that may affect scope, security, or UX

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.
