Motivation

M5 requires context analysis to produce meaningful, phase-aware summaries that explain what is included in assembled context and how budget/scoping decisions shape output. Existing checks validated policy wiring but did not provide actionable per-phase diagnostics.

Approach

This change adds a dedicated phase-analysis utility and integrates it into project-context inspect/simulate flows. It computes per-phase summaries from resolved policy views and scoped fragments, applies include/exclude and budget constraints, and reports strategize->execute->apply narrowing checks.

What Changed

Added analyze_phase_summaries(...) in src/cleveragents/application/services/context_phase_analysis.py.
- Computes per-phase metrics (fragment_count, resource_count, total_bytes, total_tokens, budget_used_ratio).
- Tracks exclusion reasons (resource_or_scope, path_rules, max_file_size, max_total_size).
- Produces human-readable summary text per phase.
- Produces narrowing diagnostics (tokens_non_increasing, bytes_non_increasing, fragments_non_increasing, overall).
Updated agents project context inspect in src/cleveragents/cli/commands/project_context.py.
- Adds structured phase_analysis payload.
- Adds per-phase analysis and narrowing output.
Updated agents project context simulate in src/cleveragents/cli/commands/project_context.py.
- Adds structured phase_analysis payload.
- Adds per-phase analysis output.
Updated Robot M5 scoped-context helper in robot/helper_m5_e2e_verification.py.
- Verifies analysis summary presence and metric completeness.
- Verifies monotonic narrowing diagnostics.
Added Behave coverage:
- features/project_context_phase_analysis.feature
- features/steps/project_context_phase_analysis_steps.py
- Covers empty context, single resource, multiple resources, and budget-constrained narrowing.
Updated CHANGELOG.md (Unreleased) with #849 entry.

Validation

Targeted scenarios:

python -m behave features/project_context_phase_analysis.feature
python -m behave features/project_context_cli.feature
python -m robot --test "ACMS Scoped Context Output Per Phase" robot/m5_e2e_verification.robot

Required nox sessions:

nox -e lint
nox -e typecheck
nox -e unit_tests
nox -e integration_tests
nox -e coverage_report
nox -e e2e_tests

Coverage remains above target (97.64%).

Closes #849

Review: feat(acms): context analysis produces meaningful summaries

Approved with minor suggestions.

Suggestions

1. Weak assertion chains (Low)
Some assertions are too permissive:

assert "total" in output.lower() or "summary" in output.lower() or "files" in output.lower()

This matches almost any output containing common English words. Consider asserting on structured output (e.g., --format json).

2. Missing negative test (Low)
No scenario tests context add with a non-existent path (patch.object(Path, "exists", return_value=True) always returns true).

What's Good

5 BDD scenarios covering multi-resource list, multi-file add, show-summary, clear-then-re-add, clear-on-empty.
Clean _mock_container helper factored for reuse across all steps.
Tests properly patch get_container — correct DI interception point.
Uses CliRunner from typer for CLI invocation — standard pattern.

Review: APPROVED

Clean 165-line module — good modular design. Phase-aware summaries with monotonic narrowing verification is well-implemented. Robot helper type annotation fixes are tangential but minor.

Good BDD coverage with 4 scenarios covering empty, single, multiple, and budget-constrained contexts.

Addressed the remaining review suggestions on this PR.

Tightened the multi-resource agents context show smoke assertion to verify the exact summary header, file count, total size, and usage hint instead of matching broad keywords.
Added a missing-path negative scenario for agents context add and asserted that the CLI reports the missing path without calling the context service.
Pushed the fixes in 88b5e293.

Validation run:

TEST_PROCESSES=9 nox -e lint
TEST_PROCESSES=9 nox -e typecheck
TEST_PROCESSES=9 nox -e unit_tests -- features/m5_acms_smoke.feature
TEST_PROCESSES=9 nox -e unit_tests
TEST_PROCESSES=9 nox -e integration_tests
TEST_PROCESSES=9 nox -e coverage_report
TEST_PROCESSES=9 nox -e e2e_tests still reports unrelated existing failures in the M1/M2 acceptance suites (CleverAgents command failed with rc=1); the M5 acceptance suite passed.
