Summary

Implement BuiltinAdapter class and MCP automatic resource slot creation. Two main changes:

1. BuiltinAdapter Class (tool/builtins/adapter.py)

Formal adapter implementing the tool adapter lifecycle pattern for built-in tools:

• discover() — returns all built-in tool descriptors (file, git, subplan tools)
• register(registry) — registers all tools in a ToolRegistry, returns registered names
• activate()/deactivate() — no-ops (built-in tools are always available)
• Wraps existing ALL_FILE_TOOLS, ALL_GIT_TOOLS, ALL_SUBPLAN_TOOLS lists
• Backward compatible — existing registration functions still work

2. MCP Resource Slot Inference (mcp/adapter.py)

New infer_resource_slots() static method on MCPToolAdapter:

• Scans MCP tool parameter schemas for file/directory/repo patterns
• Creates ResourceSlot objects with appropriate type, access mode, binding mode
• Mapping: file_path→file(rw), directory→directory(ro), repo_path→git-checkout(rw)
• Slots stored in source_metadata["resource_slots"] on registered ToolSpec objects

## Summary Implement `BuiltinAdapter` class and MCP automatic resource slot creation. Two main changes: ### 1. BuiltinAdapter Class (`tool/builtins/adapter.py`) Formal adapter implementing the tool adapter lifecycle pattern for built-in tools: - `discover()` — returns all built-in tool descriptors (file, git, subplan tools) - `register(registry)` — registers all tools in a ToolRegistry, returns registered names - `activate()`/`deactivate()` — no-ops (built-in tools are always available) - Wraps existing `ALL_FILE_TOOLS`, `ALL_GIT_TOOLS`, `ALL_SUBPLAN_TOOLS` lists - Backward compatible — existing registration functions still work ### 2. MCP Resource Slot Inference (`mcp/adapter.py`) New `infer_resource_slots()` static method on `MCPToolAdapter`: - Scans MCP tool parameter schemas for file/directory/repo patterns - Creates `ResourceSlot` objects with appropriate type, access mode, binding mode - Mapping: `file_path`→file(rw), `directory`→directory(ro), `repo_path`→git-checkout(rw) - Slots stored in `source_metadata["resource_slots"]` on registered `ToolSpec` objects ### Quality Gates | Session | Result | |---|---| | `nox -s lint` | PASS | | `nox -s typecheck` | PASS (0 errors) | | `nox -s unit_tests` | PASS (10,817 scenarios) | | `nox -s integration_tests` | PASS (6 new tests) | | `nox -s coverage_report` | 97% (>= 97%) | Closes #882

Status Update — Day 37

@freemo — Confirmed: PR #964 is ready for review. Master has been merged in today (conflicts in robot timeout files resolved).

Upstream dependencies: None. BuiltinAdapter wraps the existing register_file_tools()/register_git_tools() functions already on master. infer_resource_slots() is a new static method on McpAdapter that works independently.

Ready for @aditya's review.

Code Review — PR #964

Verdict: Request Changes (1 Major, 4 Minor, 3 Nit)

Scope: 7 files, +669/−2 (three-dot diff excluding master merge). Lint PASS, Typecheck PASS.

---

Major

BUG-1: _FILE_PARAMS includes overly generic "path" — false-positive slot creation
src/cleveragents/mcp/adapter.py:541

_FILE_PARAMS contains {"file_path", "file", "path"}. The "path" pattern is too broad — many MCP tools use path for URL routes, API endpoints, config key paths, etc. This will silently create spurious file resource slots for those tools.

Recommendation: Remove "path" or narrow to "file_path" / "filepath" only. If broad matching is needed, add a secondary heuristic (e.g., check the schema property description for "file").

---

Minor

CODE-1: No argument validation in BuiltinAdapter.register()
src/cleveragents/tool/builtins/adapter.py:76

Per CONTRIBUTING.md, all public methods must validate arguments as the first guard. register(registry) doesn't check for None, which would produce an AttributeError deep in the loop instead of at the boundary.

---

TEST-1: Missing boundary/negative tests for infer_resource_slots
features/builtin_adapter.feature

No scenarios for:

• Schema with no matching parameters (→ empty list)
• Schema with no properties key
• Multiple matching params from the same category (deduplication path)
• The generic "path" parameter specifically

---

SPEC-1: Issue #882 subtask "Refactor registration functions to use adapter" not done

The adapter wraps ALL_*_TOOLS lists but the existing register_file_tools() / register_git_tools() / register_subplan_tool() functions remain independent. The adapter is additive, not a refactor. Either update the functions to delegate, or update the issue subtask to reflect the actual (backward-compatible) approach.

---

PROCESS-1: Missing CHANGELOG entry

No entry for #882 in the Unreleased section. Required per PR Process item 6.

---

Nit

• PROCESS-2: PR is missing State/In Review label (issue has it).
• CODE-2: The three if/elif blocks in infer_resource_slots (lines 566–630) are near-identical and could be driven by a mapping dict (~65 lines → ~20).
• CODE-3: Commit body says "Also fixes pre-existing test failures" but the three-dot diff shows no test modifications — those came from the merge commit, not the author's work.

Code Review — Round 2 (new findings only)

---

Critical

BUG-2: infer_resource_slots output is dead code — source_metadata["resource_slots"] has zero consumers
src/cleveragents/mcp/adapter.py:519-540

The slot inference pipeline writes to a key that nothing reads:

1. infer_resource_slots() creates ResourceSlot objects
2. Slots are serialized to dicts and stored in source_metadata["resource_slots"] (line 540)
3. No production code reads source_metadata["resource_slots"] — confirmed via codebase-wide grep
4. The registry's find_by_resource_type() reads a different key: source_metadata.get("resource_bindings", []) (tool/registry.py:127)
5. The DB never sees it: source_metadata is not a persisted column; the DB reads resource_slots from domain Tool objects, not from ToolSpec.source_metadata
6. The CLI tool show displays resource_slots from Tool.as_cli_dict() (domain model), not from ToolSpec.source_metadata

~100 lines of infer_resource_slots, _FILE_PARAMS, _DIR_PARAMS, _REPO_PARAMS, and the slot-to-dict serialization produce write-only data.

Recommendation: Either wire into the consumption path (bridge resource_slots → resource_bindings, or populate domain Tool.resource_slots from ToolSpec.source_metadata during persistence), or remove until a consumer exists.

---

Major

BUG-3: BuiltinAdapter.register() raises ToolError on second call with same registry
src/cleveragents/tool/builtins/adapter.py:91-95

ToolRegistry.register() raises ToolError on name collision (tool/registry.py:49-53). MCPToolAdapter guards against this by pre-removing existing tools (mcp/adapter.py:496-498). BuiltinAdapter does no such check — calling register() twice on the same registry raises ToolError on every tool. No test covers this path.

---

BUG-4: Lifecycle method names diverge from MCPToolAdapter — docstring is misleading
src/cleveragents/tool/builtins/adapter.py:9-10

The docstring says the adapter "follows the same structural pattern as MCPToolAdapter" but the method names are different:

Step	MCPToolAdapter	BuiltinAdapter	AgentSkillLoader
Connect	connect()	activate()	activate()
Disconnect	disconnect()	deactivate()	deactivate()
Discover	discover_tools(tool_filter)	discover()	discover()
Register	register_tools(registry, namespace, tool_filter)	register(registry)	(none)

No shared ABC or Protocol enforces a common interface. The adapter actually follows AgentSkillLoader's naming, not MCPToolAdapter's. The register() signature also omits namespace which MCPToolAdapter requires.

Response to @hamza.khyari's Review (Rounds 1+2) — PR #964

Thank you for the deep analysis, Hamza. The dead-code finding (BUG-2) is particularly impactful — great catch tracing the full consumption path.

Critical

BUG-2 (Dead code — resource_slots has zero consumers): Confirmed. The infer_resource_slots pipeline writes to source_metadata["resource_slots"] but nothing reads it — the registry reads resource_bindings, the DB reads from domain Tool objects, and the CLI reads from Tool.as_cli_dict(). I'll wire the slots into the domain Tool.resource_slots field during MCP adapter registration, bridging ToolSpec.source_metadata → Tool.resource_slots. This makes the inference actually functional.

Major

BUG-1 ("path" too broad): Agreed — "path" matches too many unrelated parameters. Will remove it from _FILE_PARAMS and keep only "file_path", "filepath", "file".

BUG-3 (BuiltinAdapter.register raises on double-call): Will add a pre-check: skip already-registered tools (matching the MCPToolAdapter pattern of pre-removing existing tools).

BUG-4 (Lifecycle method naming divergence): Fair point. Will update the docstring to accurately reference the AgentSkillLoader naming convention and note the deliberate omission of namespace (builtin tools are always in the default namespace).

Minor

CODE-1 (No argument validation): Will add if registry is None: raise ValueError(...).
TEST-1 (Missing boundary tests): Will add scenarios for empty schema, no properties, multiple matches, and the "path" parameter specifically.
SPEC-1 (Issue subtask): Will update the issue subtask to reflect the actual backward-compatible additive approach.
PROCESS-1 (Missing CHANGELOG): Will add entry.

Nit

PROCESS-2 (Missing label): Will add State/In Review.
CODE-2 (Mapping dict): Good suggestion — will refactor the 3 if/elif blocks into a mapping-driven loop.
CODE-3 (Commit body): Will clarify that the test modifications came from the merge commit.

Working on all fixes now.

Fixed the benchmark_regression failure and merged latest master.

Root cause: RollbackSuite.time_rollback in benchmarks/checkpoint_rollback_bench.py registered a sandbox with the fake path "sandbox-path". After checkpoint_service.py was updated (commit ec4c39ae) to validate that the sandbox path is a real directory containing a .git repo, the benchmark started failing with BusinessRuleViolation: sandbox path does not exist.

Fix: Updated RollbackSuite.setup() to create a real temporary directory with git init, and added a teardown() to clean it up. The benchmark now exercises the actual rollback code path.

Also merged latest origin/master into the branch (resolved a CHANGELOG conflict).

Fixed the `benchmark_regression` failure and merged latest `master`. **Root cause:** `RollbackSuite.time_rollback` in `benchmarks/checkpoint_rollback_bench.py` registered a sandbox with the fake path `"sandbox-path"`. After `checkpoint_service.py` was updated (commit `ec4c39ae`) to validate that the sandbox path is a real directory containing a `.git` repo, the benchmark started failing with `BusinessRuleViolation: sandbox path does not exist`. **Fix:** Updated `RollbackSuite.setup()` to create a real temporary directory with `git init`, and added a `teardown()` to clean it up. The benchmark now exercises the actual rollback code path. Also merged latest `origin/master` into the branch (resolved a CHANGELOG conflict).

Labels

Clear labels   

auto/needs-reevaluation

Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.

  

controller-managed

Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.

  

auto/blocked-by-deps

PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

  

auto/ci-timeout

Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

  

auto/claimed-implementer

Currently being processed by an implementer worker.

  

auto/claimed-merge

Currently being processed by the merge driver.

  

auto/claimed-reviewer

Currently being processed by a reviewer worker.

  

auto/driver-down

Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

  

auto/invariant-violation

Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

  

auto/last-attempt-tier-0

In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-1

In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-2

In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

  

auto/last-attempt-tier-min

In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

  

Automation Tracking

Tracking issues used by the AI Automation system for agents to communicate and report.

  

auto/needs-conflict-resolution

Rebase conflict needs LLM conflict-resolver.

  

auto/needs-implementer

Failing CI needs implementer attention.

  

auto/postmortem

Documenting a driver incident or rollback.

  

auto/ready-to-merge

Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

  

auto/restart-throttled

Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  

auto/revert

Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  

auto/sentinel

Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

  

auto/stale-inactivity

No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

  

auto/unstable

Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.

  

Blocked

A ticket in a blocked state and unable to complete until some other task is completed first.
