forge agent — full session handoff

Status: Incomplete — user wants to redo in a fresh session. Design is sound but some implementation decisions need revisiting. Read this in full before starting the next session.


What this session was trying to do

Design and author a forge orchestrator agent for the kyberforge plugin. Forge is the mandatory entry point for all kyberforge plugin marketplace operations — creating, auditing, validating, and managing plugins, skills, agents, hooks, and manifests.


Session sequence

  1. Pre-reading — read marketplace-architect SKILL.md, plugin.json, existing kyberforge skills
  2. grill-with-docs — design grill covering intent, scope, and key decisions
  3. Research subagent — web research on orchestrator agent patterns (gem-orchestrator, tech-lead-orchestrator, wshobson/agents, hesreallyhim/awesome-claude-code)
  4. Second grill — resolved ambiguities surfaced by research
  5. write-agent — conflict check → description field → system prompt sections → frontmatter → file writing → write-eval

Design decisions made (all confirmed by user)

What forge is

  • Two artifacts: role skill (plugins/kyberforge/skills/forge/SKILL.md) + plugin agent (plugins/kyberforge/agents/forge.md + forge.agent.md)
  • Plugin agent supports HITL when run as main session (claude --agent kyberforge:forge) and HOTL when spawned as subagent
  • Role skill (inline /forge) not created this session — separate workstream

What forge does

  • Thin router + coordinator: classifies intent, selects skills, gates approval, drives execution
  • Absorbed all operations from marketplace-architect (audit/refactor, adopt-external, maintain/update)
  • Routes to kyberforge skills AND global skills (grill-with-docs, tdd, to-issues, etc.)
  • Mandatory entry point — specialist skills get a hard redirect added to their descriptions

What forge does NOT do

  • Write SKILL.md, agent files, eval files, or manifests directly
  • Run interactive steps of specialist skills (grilling, trigger testing, gates) — those stay in the specialist
  • Spawn subagents for steps requiring user input
  • Nested orchestration — all delegation flows through forge, flat

Two-phase coordination

  • Phase 1 (Plan, HITL): classify intent → classify complexity (TRIVIAL/LOW/MEDIUM/HIGH) → select skills → present routing plan → Gate A approval
  • Phase 2 (Execute, HOTL): spawn subagents with skills: [skill-name] preloaded → monitor via TaskList → Gate B for outputs requiring review → knowledge capture prompt
  • Fan-out capped at 3 concurrent subagents (enforced via TaskList check before each Agent call)
  • HITL re-entry during Phase 2 via needs-approval/needs-input subagent results

Tool list (plugin agent)

Read, Glob, Grep, Bash, Agent, TaskCreate, TaskUpdate, TaskList, TaskGet, SendMessage

Edit/Write deliberately excluded — all file writes happen in spawned subagents. This structurally enforces the routing-only mandate (factory-principles.md §2). Instruction-level scoping alone is insufficient (<30% compliance on complex tasks per factory principles).

Governance

Referenced by live path — no bundled copies. Core plugin is a future destination for these references.

Copilot CLI version

Phase 1 only — Agent, TaskCreate, TaskList, SendMessage, skills: preload are all Claude Code-only. Handoff comment documents this at the top of forge.agent.md.

Key research findings (sources: plugins/kyberforge/skills/forge/references/)

gem-orchestrator (awesome-copilot)

Most sophisticated example found. Key patterns:

  • Hard binary: orchestration_work vs project_work — "Never inspect, edit, run, test, debug, review, design, document, validate, or decide project work directly"
  • Complexity tiers (TRIVIAL/LOW/MEDIUM/HIGH) to scale planning depth
  • Wave-based parallel execution with conflict tracking
  • Typed failure handling (transient, fixable, needs-replan, escalate, needs-approval)
  • Knowledge capture as a first-class orchestration responsibility

tech-lead-orchestrator (vijaythecoder/awesome-claude-agents)

  • Read-only tool list (Read, Grep, Glob, LS, Bash — no Write/Edit) structurally enforces routing-only mandate
  • Single HITL gate after research phase, before specialist invocation
  • Agent discovery from system context, not hardcoded list
  • Runs on Opus for planning quality

wshobson/agents marketplace

  • team-lead agent as structural blueprint: Agent, TaskCreate/Update/List, SendMessage, TeamCreate/Delete
  • "Decompose before delegating" — classify before routing, never mid-delegation
  • File ownership rule: one owner per file for parallel dispatch safety
  • Team/fan-out cap: 2–5 teammates max; coordination overhead > 4 is explicitly warned

hesreallyhim/awesome-claude-code + community

  • user-invocable: false is the canonical pattern for specialist agents — coordinator is the only user surface
  • Flat coordination constraint: "Subagents cannot spawn subagents. All delegation flows through Main Agent."
  • Cross-team/cross-plugin delegation is an open unsolved problem — forge's plugin marketplace model is a novel solution
  • Ralph Orchestrator: clearest two-phase (plan/run) split found; HITL re-entry via events, not polling

What's novel about forge

No existing implementation found combining: thin router + plugin-scoped specialists + explicit interactive-to-autonomous phase handoff. Forge's design is addressing an open problem in the agentic tooling community.


Conflict check results (3 tensions found and resolved)

Tension 1 — Edit/Write without structural enforcement

  • Factory principles §2: instruction-level scoping is probabilistic (<30% on complex tasks)
  • Resolution: Edit/Write removed from plugin agent tool list entirely. Role skill revisits this separately.

Tension 2 — Fan-out cap has no enforcement mechanism

  • Resolution: Guard clause added to Phase 2: check TaskList count before each Agent call; if ≥ 3, queue and wait. Makes it logic, not a soft directive.

Tension 3 — "Mandatory entry point" vs user-invocable specialists

  • Bypassing forge = bypassing Phase 1 HITL gate (constitution §5 violation)
  • Resolution: Specialist descriptions get hard redirect added. Documented as required consequent action in ADR-0013.

Lessons from this session

  1. grill-with-docs before write-agent is the right sequence — by the time write-agent ran, most decisions were already locked and the session was smooth.

  2. The conflict check sub-agent found real issues — Tension 1 (Edit/Write in tool list) was a genuine design flaw caught before writing. Don't skip it.

  3. Research subagents are valuable but need sequential not parallel execution — user corrected a parallel launch attempt early in the session. Research should inform the grill, not run alongside it.

  4. The two-phase insight came from a user correction — the assumption that "role skills can't spawn subagents" was wrong. Role skills run inline and CAN use the Agent tool. The platform capability check (asking the user to verify the assumption) was the right call.

  5. Plugin agent vs role skill distinction — the same agent file supports HITL (when run as main session via --agent) and HOTL (when spawned as subagent). These are not two separate designs — they're two invocation modes of the same file.

  6. The write-agent process is very confirmation-heavy — 5 sections × 1 confirmation each + frontmatter + description + eval plan. This is by design (HITL gates on content) but the user's "go ahead" cadence suggests the sections were clear enough that less friction would have been welcome. Consider: could write-agent propose a full draft and confirm as a batch for cases where extensive pre-grilling has already been done?


What the user is not happy with

User said: "I am not fully happy with some things" — did not specify what. Possible candidates based on the session:

  • The system prompt body may need restructuring or expansion
  • The role skill was never addressed this session (only the plugin agent was created)
  • The write-agent process may have felt mechanical
  • Something in the design decisions (tool list, two-phase model, complexity tiers, etc.)

Recommended first action in the next session: ask the user what specifically they want to change before doing anything.


  1. Read: docs/adr/0013-forge-orchestrator-design.md, CONTEXT.md (forge/Two-phase/Core plugin glossary terms), plugins/kyberforge/agents/forge.md
  2. Ask: "What specifically are you not happy with from the previous session?"
  3. Decide: revise the plugin agent files, or proceed to the role skill, or tackle the follow-on actions (specialist redirects, marketplace-architect retirement)
  4. Do NOT commit any of this session's work until the user is satisfied with the design
