* test(#2951): pin the absent-evidence provenance contract (failing first) 17 tests / 22 anchors on the deployed agent text. Measured against the parent commit: 20 anchors fail, 2 pass. The two that pass are the sibling-integrity guards on the package-name and in-repo-value rules -- green before and after is their intended signature. Refs #2951 * enhance(#2951): refuse [VERIFIED] for a compatibility claim resting on absent metadata A claim of the form "X does not support Y" drawn from MISSING metadata -- no python_requires, no engines field, no per-version classifier, no changelog entry, no matching support-matrix row -- no longer earns [VERIFIED] however authoritative the source consulted. An absence is silence about every value, so the same evidence would "prove" both the version being ruled out and the version being standardized on. The only route from an absence to [VERIFIED] is a positive falsification attempt with its failing output pasted; everything short of that is [ASSUMED], which the file already routes to "needs user confirmation before becoming a locked decision". Third member of the family beside the package-name and in-repo-value provenance rules, mirroring PR #2768's shape. A present declared constraint and an affirmatively documented incompatibility are untouched. Closes #2951 * fix(#2951): close the allow-list ambiguity and the mutation gap review found Findings from the isolated adversarial pass and the two-axis review, all fixed: MAJOR (x2, one root cause) -- the absence clause and the present-constraint carve-out gave opposite verdicts on the same evidence for the commonest real case: a classifier list enumerating :: 3.9 through :: 3.13 with no :: 3.14. A researcher could read the enumerated list as a "declared" positive constraint and re-earn [VERIFIED], which is also the evasion vector. The rule now states the decision procedure -- does the declaration bound EVERY value or only the ones it names -- and closes the positive-reframing restatement explicitly. New contract test pins all four clauses. MAJOR -- 'licenses a positive falsification attempt as the route to [VERIFIED]' asserted two independent substrings and never that the route lands on [VERIFIED]. A mutant swapping the tag for [CITED] or [ASSUMED] inverted the rule and survived all 17 tests. Now pinned as one joined sentence. MINOR -- the attributable-failure test regex-matched illustrative examples ("a missing certificate, a wrong host"), so a copy-edit would break it for no reason; relaxed to the substantive clause. The no-paraphrase guard counted only the heading, missing the drift mode in its own name; it now also pins the core proposition to one occurrence, and the test name matches what it checks. An off-by-one in the new allow-list regex bound (141 actual vs 140) is fixed. MINOR -- docs/AGENTS.md listed four of the five governed absence forms while the agent prose, docs/COMMANDS.md and the changeset listed five; three copies disagreeing on list membership is the drift this repo treats as a defect. SCOPE -- removed docs/how-to/verify-a-dependency-compatibility-claim.md and its docs/README.md index line. Both reviewers flagged them as a seventh and eighth surface beyond the six the requester capped, and CONTRIBUTING's "Agent or skill change" row requires only docs/AGENTS.md. The actionable four-case guidance is retained in docs/COMMANDS.md, which is inside the approved scope. Ack byte figures corrected for the final size: 44250 -> 46602 (+2352), 2550 bytes headroom under the LARGE cap of 49152. Refs #2951 * docs(#2951): restore the how-to the phase gate requires Reverses the removal in 6404b43d3. Both /code-review axes had flagged docs/how-to/verify-a-dependency-compatibility-claim.md and its docs/README.md index line as a seventh and eighth surface beyond the six the requester capped, and CONTRIBUTING.md's required-docs row for an "Agent or skill change" names only docs/AGENTS.md, so they were dropped. gsd-phase-gate.cjs then denied gh pr create: it refuses when the recorded enablement sequence has more than one step and the how-to quadrant is empty. The sequence here is genuinely four steps -- run plan-phase, read the [ASSUMED] claim, probe or cite or accept it unlocked, then answer discuss-phase's checkpoint -- and the last step lands on a different capability's surface, so a reference table cannot carry it. Compressing the sequence to one step to unlock howToSkipReason would be gaming the gate, which is the same Goodhart failure this whole change exists to close. A machine-enforced repo gate outranks two reviewers' scope preference and my own reading, so the page is restored and the PR body discloses the two extra surfaces instead of hiding them. Reverting is a one-file change if a maintainer prefers the tighter scope. Refs #2951 * chore(#2951): backfill the changeset PR number pr: 0 -> 3718 now that the real PR exists. The placeholder fails scripts/changeset/lint.cjs with fail_invalid_fragment, which also blocks lint-docs-required from consuming the fragment. Refs #2951 --------- Co-authored-by: sim <sim@local>

GSD Agent Reference
Full role cards for 21 primary agents plus concise stubs for 12 advanced/specialized agents (33 shipped agents total). The
agents/directory anddocs/INVENTORY.mdare the authoritative roster; see Architecture for context.
Overview
GSD uses a multi-agent architecture where thin orchestrators (workflow files) spawn specialized agents with fresh context windows. Each agent has a focused role, limited tool access, and produces specific artifacts.
Required reading (#3423): the canonical spawn-block tag is <required_reading> on BOTH sides — orchestrators emit it, and gating agents enforce it ("you MUST use the Read tool to load every file listed there before performing any other actions"). The legacy <files_to_read> emit-tag is retired and banned repo-wide by tests/agent-required-reading-consistency.test.cjs, because a mismatched pair silently disarms the enforcement clause.
Agent Categories
The table below covers the 21 primary agents detailed in this section. Thirteen additional shipped agents (pattern-mapper, debug-session-manager, code-reviewer, code-fixer, ai-researcher, domain-researcher, eval-planner, eval-auditor, framework-selector, intel-updater, doc-classifier, doc-synthesizer, mempalace-curator) have concise stubs in the Advanced and Specialized Agents section below.

- Enforces a comment-text discipline HARD GATE at plan-write time (
verify.plan-structure): a literal that an acceptance criterion negative-greps for (grep -c 'LIT' file == 0) must not appear verbatim in an<action>body; violations fail plan creation. Use<!-- planner-discipline-allow: LIT -->to allowlist a legitimate occurrence. (#429)
gsd-roadmapper
Role: Creates project roadmaps with phase breakdown and requirement mapping.
| Property | Value |
|---|---|
| Spawned by | /gsd-new-project |
| Parallelism | Single instance |
| Tools | Read, Write, Bash, Glob, Grep, Skill |
| Model (balanced) | Sonnet |
| Color | Purple |
| Produces | ROADMAP.md |
Key behaviors:

Key behaviors:
- Fresh 200K context window per plan
- Follows XML task instructions precisely
- Atomic git commit per completed task
- Handles task types: auto, tracer, checkpoint (human-verify, decision, human-action)
- Tracer feedback gate: after a
tracerslice, verifies it end-to-end before expansion tasks — autonomous runs halt on failure; interactive runs emit a human-verify checkpoint - Reports deviations from plan in SUMMARY.md
- Invokes node repair on verification failure
gsd-plan-checker
Role: Verifies plans will achieve phase goals before execution.
| Property | Value |
|---|---|
| Spawned by | /gsd-plan-phase (verification loop, max 3 iterations) |

| 7c | Architectural tier compliance (when RESEARCH.md defines a responsibility map) |
| 8 | Nyquist compliance (when enabled) |
| 9 | Cross-plan data contracts |
| 10 | CLAUDE.md compliance |
| 11 | Research resolution |
| 12 | Pattern compliance |
Two further dimensions carry no number: Verify Command Format Sanity and Numeric/Factual Claim Authority.
gsd-integration-checker
Role: Verifies cross-phase integration and end-to-end flows.
| Property | Value |
|---|---|
| Spawned by | /gsd-audit-milestone |
| Parallelism | Single instance |

gsd-ui-checker
Role: Validates UI-SPEC.md design contracts against quality dimensions.
| Property | Value |
|---|---|
| Spawned by | /gsd-ui-phase (validation loop, max 2 iterations) |
| Parallelism | Single instance |
| Tools | Read, Bash, Glob, Grep, Skill |
| Disallowed Tools | Write, Edit, MultiEdit |
| Model (balanced) | Sonnet |
| Color | Cyan |
| Produces | BLOCK/FLAG/PASS verdict |
Key behaviors:
- Adversarial stance / "The Auditor" (#1578): applies explicit BLOCK/FLAG/PASS tiers and an anti-capitulation rule that resists author-framing pressure while still allowing self-correction when the prior dimension application was mistaken. Persona effects are strongest on Sonnet-class reasoning and unvalidated on budget/Haiku-class routing; the criteria and evidence remain authoritative.
gsd-verifier
Role: Verifies phase goal achievement through goal-backward analysis.
| Property | Value |
|---|---|
| Spawned by | /gsd-execute-phase (after all executors complete) |
| Parallelism | Single instance |
| Tools | Read, Write, Bash, Grep, Glob, Skill |
| Disallowed Tools | Edit, MultiEdit |
| Model (balanced) | Sonnet |
| Color | Green |
| Produces | {phase}-VERIFICATION.md |
Key behaviors:
-
Checks codebase against phase goals, not just task completion
-
PASS/FAIL with specific evidence
-
Logs issues for
/gsd-verify-workto address -
Milestone scope filtering: gaps addressed in later phases are marked as "deferred", not reported as failures (v1.32)
-
Test quality audit (v1.32): verifies that tests prove what they claim by checking for disabled/skipped tests on requirements, circular test patterns (system generating its own expected values), assertion strength (existence vs. value vs. behavioral), and expected value provenance. Blockers from test quality audit override an otherwise passing verification
-
Runs the full workspace test suite at most once per verification — proves a test exists by enumeration and that it passes via a single named test, never re-running the whole suite per must-have.
-
Behavior-dependent calibration (#966): a must-have that asserts a state transition or a cancellation/cleanup/ordering invariant is marked
⚠️ PRESENT_BEHAVIOR_UNVERIFIED(notVERIFIED) when no test exercises it — excluded from theverified_truthsscore, counted in thebehavior_unverifiedfrontmatter field, and routed to human verification, so a cleanN/Ncertifies behavioral evidence rather than mere symbol presence. -
Coincidental-reliance advisory (#1955): a truth that reaches
✓ VERIFIEDis additionally asked why it holds. When the recorded evidence shows the truth holding for an incidental reason —undeclared-precondition,incidental-ordering, orfixture-only— the verdict is qualified as✓ VERIFIED (coincidental-reliance)and the truth is listed in thecoincidental_reliance_itemsfrontmatter field with what to harden. This is advisory: the base✓ VERIFIEDtoken is unchanged, the truth still counts towardverified_truths, the overallstatusis unaffected, and no human-verification item is emitted — a passing phase still passes. It classifies evidence the verifier already gathered rather than asking it to rate its own confidence — but it is honestly an endogenous check, andgsd-core/references/honest-verifier.mdrecords that endogenous gates are measurably weaker than the exogenousbackstoptag it routes on. Advisory status is the consequence, not a coincidence: a miss costs exactly today's behaviour (a plain✓ VERIFIED) and a false positive costs one line of prose, never a failed phase, so a weaker mechanism is affordable here in a way it would not be on a pass/fail axis. Its precision is unmeasured. It complements the two existing axes:PRESENT_BEHAVIOR_UNVERIFIEDis no behavioral evidence,insufficient_specis an under-specified truth, and this is evidence that exists and passes for the wrong reason.The advisory is carried by two surfaces.
agents/gsd-verifier.md(Step 3, sub-step 5c) holds the detection rule, and the verifier's eagerly-importedgsd-core/references/verifier-phase-gates.mdpoints at the canonical report template@~/.claude/gsd-core/templates/verification-report.md, whose## Guidelinescarry the same instruction. (The former third surface, the retiredverify-phaseworkflow, was deleted as an orphan in #1892 — every verification path is subagent-shaped today.)
gsd-nyquist-auditor
Role: Fills Nyquist validation gaps by generating tests.
| Property | Value |
|---|---|
| Spawned by | /gsd-validate-phase |
| Parallelism | Single instance |
| Tools | Read, Write, Edit, Bash, Glob, Grep, Skill |
| Model (balanced) | Sonnet |
| Color | Purple |
| Produces | Test files, updated VALIDATION.md |
Key behaviors:
- Never modifies implementation code — only test files
- Max 3 attempts per gap
- Flags implementation bugs as escalations for user
gsd-ui-auditor
Role: Retroactive 6-pillar visual audit of implemented frontend code.
| Property | Value |
|---|---|
| Spawned by | /gsd-ui-review |
| Parallelism | Single instance |
| Tools | Read, Write, Bash, Grep, Glob, Skill |
| Disallowed Tools | Edit, MultiEdit |
| Model (balanced) | Sonnet |
| Color | Pink |
| Produces | {phase}-UI-REVIEW.md with scores |
6 Audit Pillars (scored 1-4):
- Copywriting
- Visuals
- Color
- Typography
- Spacing
- Experience Design
gsd-codebase-mapper
Role: Explores codebase and writes structured analysis documents.
| Property | Value |
|---|---|
| Spawned by | /gsd-map-codebase, post-execute drift gate in /gsd-execute-phase |
| Parallelism | 4 instances (tech, architecture, quality, concerns) |
| Tools | Read, Bash, Grep, Glob, Write, Skill |
| Model (balanced) | Haiku |
| Color | Cyan |
| Produces | .planning/codebase/*.md (7 documents, with last_mapped_commit frontmatter) |
Key behaviors:
- Read-only exploration + structured output
- Writes documents directly to disk
- No reasoning required — pattern extraction from file contents
--paths <p1,p2,...> scope hint (#2003):
Accepts an optional --paths directive in its prompt. When present, the
mapper restricts Glob/Grep/Bash exploration to the listed repo-relative path
prefixes — this is the incremental-remap path used by the post-execute
codebase-drift gate. Path values that contain .., start with /, or
include shell metacharacters are rejected. Without the hint, the mapper
runs its default whole-repo scan.
gsd-debugger
Role: Investigates bugs using scientific method with persistent state.
| Property | Value |
|---|---|
| Spawned by | /gsd-debug, /gsd-verify-work (for failures) |
| Parallelism | Single instance (interactive) |
| Tools | Read, Write, Edit, Bash, Grep, Glob, Skill, WebSearch |
| Model (balanced) | Sonnet |
| Color | Orange |
| Produces | .planning/debug/*.md, knowledge-base updates |
Debug Session Lifecycle:
gathering → investigating → fixing → verifying → awaiting_human_verify → resolved
Key behaviors:
- Tracks hypotheses, evidence, and eliminated theories
- State persists across context resets
- Requires human verification before marking resolved
- Runs a multi-signal fix-acceptance guardrail (mutation check, no-op/deletion detector, adjacent tests, revert-and-reconfirm) before accepting a fix; degrades gracefully when Stryker or a test suite is absent
- Ranks suspect code by Ochiai suspiciousness from test pass/fail coverage (spectrum-based fault localization) before forming hypotheses; skips cleanly when no coverage exists
- Branches root-cause analysis across ≥2 Ishikawa categories and applies an AND-gate check before committing root_cause (guards against 5-Whys single-cause bias); root_cause may hold a set when the AND-gate fires
- Classifies each failure as Bohrbug / Heisenbug-Mandelbug / Concurrency at Phase 1.75 and routes the investigation technique accordingly (routes Bohrbugs to SBFL+bisect, Heisenbugs to record-replay/stability with SBFL skipped, Concurrency to the atomicity/order/deadlock checklist)
- Hardens regression tests via PBT shrinking (minimized counterexample as the seed), explicit oracle classification (specified/derived/metamorphic/implicit), and boundary neighbors around the fixed equivalence class
- Emits a blameless-postmortem Prevention block at resolution (branching 5-Whys, why-wasn't-this-caught, a concrete recurrence guard) and records
why_not_caught+recurrence_guardin the knowledge base so the same bug class is prevented, not just fixed - Recalls prior resolved sessions semantically via MemPalace at Phase 0 (top-k meaning-similar), catching same-root-cause/different-wording cases keyword overlap misses; falls back to keyword matching when MemPalace is absent
- Appends to persistent knowledge base on resolution
- Consults knowledge base on new sessions
gsd-user-profiler
Role: Analyzes session messages across 8 behavioral dimensions to produce a scored developer profile.
| Property | Value |
|---|---|
| Spawned by | /gsd-profile-user |
| Parallelism | Single instance |
| Tools | Read |
| Model (balanced) | Sonnet |
| Color | Purple |
| Produces | USER-PROFILE.md, CLAUDE.md profile section |
Behavioral Dimensions: Communication style, decision patterns, debugging approach, UX preferences, vendor choices, frustration triggers, learning style, explanation depth.
Key behaviors:
- Read-only agent — analyzes extracted session data, does not modify files
- Produces scored dimensions with confidence levels and evidence citations
- Questionnaire fallback when session history is unavailable
gsd-doc-writer
Role: Writes and updates project documentation. Spawned with a doc_assignment block specifying doc type, mode, and project context.
| Property | Value |
|---|---|
| Spawned by | /gsd-docs-update |
| Parallelism | Multiple instances (one per doc type) |
| Tools | Read, Bash, Grep, Glob, Write, Edit, Skill |
| Model (balanced) | Sonnet |
| Color | Purple |
| Produces | Project documentation files (README, architecture, API docs, etc.) |
Key behaviors:
- Supports modes: create, update, supplement, fix
- Handles doc types: readme, architecture, getting_started, development, testing, api, configuration, deployment, contributing, custom
- Monorepo-aware: can generate per-package READMEs
- Fix mode accepts failure objects from gsd-doc-verifier for targeted corrections
- Writes directly to disk — does not return content to orchestrator
gsd-doc-verifier
Role: Verifies factual claims in generated documentation against the live codebase.
| Property | Value |
|---|---|
| Spawned by | /gsd-docs-update (after doc-writer completes) |
| Parallelism | Multiple instances (one per doc file) |
| Tools | Read, Write, Bash, Grep, Glob |
| Disallowed Tools | Edit, MultiEdit |
| Model (balanced) | Sonnet |
| Color | Orange |
| Produces | Structured JSON verification results per doc |
Key behaviors:
- Extracts checkable claims (file paths, function names, CLI commands, config keys)
- Verifies each claim against filesystem using tools only — no assumptions
- Writes structured JSON result file for orchestrator to process
- Failed claims feed back to doc-writer in fix mode
gsd-security-auditor
Role: Verifies threat mitigations from PLAN.md threat model exist in implemented code.
| Property | Value |
|---|---|
| Spawned by | /gsd-secure-phase |
| Parallelism | Single instance |
| Tools | Read, Bash, Glob, Grep, Skill |
| Model (balanced) | Sonnet |
| Color | Red |
| Produces | Structured verdict (SECURED / OPEN_THREATS / ESCALATE) — orchestrator writes {phase}-SECURITY.md (#2119) |
Key behaviors:
- Verifies each threat by its declared disposition (mitigate / accept / transfer)
- Does NOT scan blindly for new vulnerabilities — verifies declared mitigations only
- Implementation files are read-only — never patches implementation code
- Unmitigated threats reported as OPEN_THREATS or ESCALATE
- Supports ASVS levels 1/2/3 for verification depth
Advanced and Specialized Agents
Twelve additional agents ship under agents/gsd-*.md and are used by specialty workflows (/gsd-ai-integration-phase, /gsd-eval-review, /gsd-code-review, /gsd-code-review --fix, /gsd-debug, /gsd-map-codebase --query, /gsd-ingest-docs) and by the planner pipeline. Each carries full frontmatter in its agent file; the stubs below are concise by design. The authoritative roster (with spawner and primary-doc status per agent) lives in docs/INVENTORY.md.
gsd-pattern-mapper
Role: Read-only codebase analysis that maps files-to-be-created or modified to their closest existing analogs, producing PATTERNS.md for the planner to consume.

|---|---|
| Spawned by | /gsd-plan-phase (between research and planning) |
| Parallelism | Single instance |
| Tools | Read, Bash, Glob, Grep, Write |
| Model (balanced) | Sonnet |
| Color | Purple |
| Produces | PATTERNS.md in the phase directory |
Key behaviors:
- Extracts file list from CONTEXT.md and RESEARCH.md; classifies each by role (controller, component, service, model, middleware, utility, config, test) and data flow (CRUD, streaming, file I/O, event-driven, request-response)
- Searches for the closest existing analog per file and extracts concrete code excerpts (imports, auth patterns, core pattern, error handling)
- Strictly read-only against source; only writes
PATTERNS.md
gsd-debug-session-manager
Role: Runs the full /gsd-debug checkpoint-and-continuation loop in an isolated context so the orchestrator's main context stays lean; spawns gsd-debugger agents, dispatches specialist skills, and handles user checkpoints via AskUserQuestion.
| Property | Value |
|---|---|
| Spawned by | /gsd-debug |
| Parallelism | Single instance (interactive, stateful) |
| Tools | Read, Write, Edit, Bash, Grep, Glob, Agent, AskUserQuestion |
| Model (balanced) | Sonnet |
| Color | Orange |
| Produces | Compact summary returned to main context; evolves the .planning/debug/{slug}.md session file |
Key behaviors:
- Reads the debug session file first; passes file paths (not inlined contents) to spawned agents to respect context budget
- Treats all user-supplied AskUserQuestion content as data-only, wrapped in DATA_START/DATA_END markers
- Coordinates TDD gates and reasoning checkpoints introduced in v1.36.0
gsd-code-reviewer
Role: Reviews source files for bugs, security vulnerabilities, and code-quality problems; produces a structured REVIEW.md with severity-classified findings.
| Property | Value |
|---|---|
| Spawned by | /gsd-code-review |
| Parallelism | Typically single instance per review scope |
| Tools | Read, Write, Bash, Grep, Glob, Skill |
| Model (balanced) | Sonnet |
| Color | Orange |
| Produces | REVIEW.md in the phase directory |
Key behaviors:
- Detects bugs (logic errors, null/undefined checks, off-by-one, type mismatches, unreachable code), security issues (injection, XSS, hardcoded secrets, insecure crypto), and quality issues
- Honors
CLAUDE.mdproject conventions and.claude/skills//.agents/skills/rules when present - Read-only against implementation source — never modifies code under review
gsd-code-fixer
Role: Applies fixes to findings from REVIEW.md with intelligent (non-blind) patching and atomic per-fix commits; produces REVIEW-FIX.md.
| Property | Value |
|---|---|
| Spawned by | /gsd-code-review --fix |
| Parallelism | Single instance |
| Tools | Read, Edit, Write, Bash, Grep, Glob, Skill |
| Model (balanced) | Sonnet |
| Color | Green |
| Produces | REVIEW-FIX.md; one atomic git commit per applied fix |
Key behaviors:
- Treats
REVIEW.mdsuggestions as guidance, not a patch to apply literally - Commits each fix atomically so review and rollback stay granular
- Honors
CLAUDE.mdand project-skill rules during fixes
gsd-ai-researcher
Role: Researches a chosen AI/LLM framework's official documentation and distills it into implementation-ready guidance — framework quick reference, patterns, and pitfalls — for the Section 3–4b body of AI-SPEC.md.
| Property | Value |
|---|---|
| Spawned by | /gsd-ai-integration-phase |
| Parallelism | Single instance (sequential with domain-researcher / eval-planner) |
| Tools | Read, Write, Edit, Bash, Grep, Glob, WebFetch, WebSearch, mcp__context7__, mcp__plugin_context7_context7__ |
| Model (balanced) | Sonnet |
| Color | Green |
| Produces | Sections 3–4b of AI-SPEC.md (framework quick reference + implementation guidance) |
Key behaviors:
- Uses Context7 MCP when available; falls back to the
ctx7CLI via Bash when MCP tools are stripped from the agent - Anchors guidance to the specific use case, not generic framework overviews
gsd-domain-researcher
Role: Surfaces the business-domain and real-world evaluation context for an AI system — expert rubric ingredients, failure modes, regulatory context — before the eval-planner turns it into measurable rubrics. Writes Section 1b of AI-SPEC.md.
| Property | Value |
|---|---|
| Spawned by | /gsd-ai-integration-phase |
| Parallelism | Single instance |
| Tools | Read, Write, Edit, Bash, Grep, Glob, WebSearch, WebFetch, mcp__context7__, mcp__plugin_context7_context7__ |
| Model (balanced) | Sonnet |
| Color | Purple |
| Produces | Section 1b of AI-SPEC.md |
Key behaviors:
- Researches the domain, not the technical framework — its output feeds the eval-planner downstream
- Produces rubric ingredients that downstream evaluators can turn into measurable criteria
gsd-eval-planner
Role: Designs the structured evaluation strategy for an AI phase — failure modes, eval dimensions with rubrics, tooling, reference dataset, guardrails, production monitoring. Writes Sections 5–7 of AI-SPEC.md.
| Property | Value |
|---|---|
| Spawned by | /gsd-ai-integration-phase |
| Parallelism | Single instance (sequential after domain-researcher) |
| Tools | Read, Write, Edit, Bash, Grep, Glob, AskUserQuestion |
| Model (balanced) | Sonnet |
| Color | Orange |
| Produces | Sections 5–7 of AI-SPEC.md (Evaluation Strategy, Guardrails, Production Monitoring) |
Required reading: gsd-core/references/ai-evals.md (evaluation framework).
Key behaviors:
- Turns domain-researcher rubric ingredients into measurable, tooled evaluation criteria
- Does not re-derive domain context — reads Section 1 and 1b of
AI-SPEC.mdas established input
gsd-eval-auditor
Role: Retroactive audit of an implemented AI phase's evaluation coverage against its planned AI-SPEC.md eval strategy. Scores each eval dimension COVERED / PARTIAL / MISSING and produces EVAL-REVIEW.md.
| Property | Value |
|---|---|
| Spawned by | /gsd-eval-review |
| Parallelism | Single instance |
| Tools | Read, Write, Bash, Grep, Glob, Skill |
| Disallowed Tools | Edit, MultiEdit |
| Model (balanced) | Sonnet |
| Color | Red |
| Produces | EVAL-REVIEW.md with dimension scores, findings, and remediation guidance |
Required reading: gsd-core/references/ai-evals.md.
Key behaviors:
- Compares the implemented codebase against the planned eval strategy — never re-plans
- Reads implementation files incrementally to respect context budget
gsd-framework-selector
Role: Interactive decision-matrix agent that runs a ≤6-question interview, scores candidate AI/LLM frameworks, and returns a ranked recommendation with rationale.
| Property | Value |
|---|---|
| Spawned by | /gsd-ai-integration-phase |
| Parallelism | Single instance (interactive) |
| Tools | Read, Bash, Grep, Glob, WebSearch, AskUserQuestion |
| Model (balanced) | Sonnet |
| Color | Cyan |
| Produces | Scored ranked recommendation (structured return to orchestrator) |
Required reading: gsd-core/references/ai-frameworks.md (decision matrix).
Key behaviors:
- Scans
package.json,pyproject.toml,requirements*.txtfor existing AI libraries before the interview to avoid recommending a rejected framework - Asks only what the codebase scan and CONTEXT.md have not already answered
gsd-intel-updater
Role: Reads project source and writes structured intel (JSON + Markdown) into .planning/intel/, building a queryable codebase knowledge base that other agents use instead of performing expensive fresh exploration.
| Property | Value |
|---|---|
| Spawned by | /gsd-map-codebase --query (refresh / update flows) |
| Parallelism | Single instance |
| Tools | Read, Write, Bash, Glob, Grep |
| Model (balanced) | Sonnet |
| Color | Cyan |
| Produces | .planning/intel/*.json (and companion Markdown) consumed by gsd-tools query intel |
Key behaviors:
- Writes current state only — no temporal language, every claim references an actual file path
- Uses Glob / Read / Grep for cross-platform correctness; Bash is reserved for
gsd-tools query intelCLI calls
gsd-doc-classifier
Role: Classifies a single planning document as ADR, PRD, SPEC, DOC, or UNKNOWN. Extracts title, scope summary, and cross-references. Writes a JSON classification file used by gsd-doc-synthesizer to build a consolidated context.
| Property | Value |
|---|---|
| Spawned by | /gsd-ingest-docs (parallel fan-out over the doc corpus) |
| Parallelism | One instance per input document |
| Tools | Read, Write, Grep, Glob |
| Model (balanced) | Haiku |
| Color | Yellow |
| Produces | One JSON classification file per input doc (type, title, scope, refs) |
Key behaviors:
- Single-doc scope — never synthesizes or resolves conflicts (that is the synthesizer's job)
- Heuristic-first classification; returns UNKNOWN when the doc lacks type signals rather than guessing
- Extraction discipline (#1578): few-shot input→output exemplars plus a terminal schema restatement; marks a field absent rather than fabricating a value when the doc lacks the signal.
gsd-doc-synthesizer
Role: Synthesizes classified planning docs into a single consolidated context. Applies precedence rules, detects cross-reference cycles, enforces LOCKED-vs-LOCKED hard-blocks, and writes INGEST-CONFLICTS.md with three buckets (auto-resolved, competing-variants, unresolved-blockers).
| Property | Value |
|---|---|
| Spawned by | /gsd-ingest-docs (after classifier fan-in) |
| Parallelism | Single instance |
| Tools | Read, Write, Grep, Glob, Bash |
| Model (balanced) | Sonnet |
| Color | Orange |
| Produces | Consolidated context for .planning/ plus INGEST-CONFLICTS.md report |
Key behaviors:
- Hard-blocks on LOCKED-vs-LOCKED ADR contradictions instead of silently picking a winner
- Follows the
references/doc-conflict-engine.mdcontract so/gsd-importand/gsd-ingest-docsproduce consistent conflict reports - Extraction discipline (#1578): few-shot exemplars plus a terminal schema restatement and a mark-absent (no-fabrication) rule for missing fields.
gsd-mempalace-curator
Role: Ship-time memory curation — writes per-agent diary entries, proposes and creates cross-project tunnels, runs wing-scoped sync pruning, and mirrors extract-learnings output into MemPalace's temporal knowledge graph with provenance.
| Property | Value |
|---|---|
| Spawned by | MemPalace capability at ship:post (when mempalace.enabled = true); diary/tunnels/KG-mirror are then refined by their own toggles |
| Parallelism | Single instance |
| Tools | Read, Bash, Grep, Glob |
| Model (balanced) | Sonnet |
| Produces | Diary entry in MemPalace, wing tunnel proposals, KG provenance records |
Key behaviors:
- Best-effort only — every operation is
onError: skip; a MemPalace failure never halts the loop - Wing-scoped sync pruning (
mempalace sync --wing <wing> --apply) — never runs a global prune - Cross-project tunnel proposals when
mempalace.cross_project_tunnels = true - Mirrors
extract-learningsdecisions, lessons, patterns, and surprises into the KG withsource_drawer_idprovenance - Requires MemPalace MCP server or CLI to be reachable; writes a skip-notice stub when unavailable

Principle of Least Privilege:
- Checkers are read-only (no Write/Edit) — they evaluate, never modify
- Researchers have web access — they need current ecosystem information
- Executors have Edit — they modify code but not web access
- Mappers have Write — they write analysis documents but not Edit (no code changes)
Completion Contracts (machine-enforced)
Every agent's return contract is declared in gsd-core/references/agent-contracts.md's Agent Registry table — (Agent, Completion Markers, Consumed by, Kind) — and enforced by npm run check:contract-drift (part of lint:ci).
The Kind column records how a caller actually detects the agent's completion:
| Kind | Detection mechanism |
|---|---|
sentinel-match |
Exact-case string match against a declared marker (by a workflow, command, or another agent) |
artifact+query |
The agent writes a file; the caller reads or queries that artifact |
structured-return |
The agent returns parseable sections/JSON inline; the caller reads the return text |
When you add an agent or change what it returns, update its registry row in the same change — a stale row is a build failure, not a documentation cleanup for later. Markers are extracted fence-aware (a heading inside a fenced block is the emitted template; the same words outside a fence are prose documentation), producer scope includes @-included gsd-core/references/** files, and consumers are matched exact-case (a case-insensitive hit is reported as a collision, never accepted). A marker that is deliberately emitted but matched by nothing carries an (unconsumed: <reason>) annotation — an auditable exemption that waives only the consumer requirement.
The same check also enforces the read-tag pairing: whenever a declared consumer emits <required_reading>, the producing agent's instructions must reference the gate (directly or via an @-included reference) — and the retired <files_to_read> vocabulary may not reappear under workflows/, commands/, or agents/.
