[BUG] [v0.0.7] cortex agent list --filter inflates hidden count — visible non-matching agents counted as hidden (list.rs:131)

[nightmare0329]

Project

Repository: CortexLM/cortex
Version: v0.0.7
Component: cortex agent list — hidden count display (src/cortex-cli/src/agent_cmd/handlers/list.rs)

Description

When using cortex agent list --filter <pattern>, the footer message incorrectly reports the number of "hidden" agents. The hidden count is computed as:

// src/cortex-cli/src/agent_cmd/handlers/list.rs:131-135
let hidden_count = if !args.all {
    agents.len() - filtered.len()  // BUG: counts ALL non-displayed agents as "hidden"
} else {
    0
};

agents.len() is the total of ALL agents. filtered.len() is agents after all filters (hidden flag + mode + pattern). So agents.len() - filtered.len() includes both:

1. Truly hidden agents (have hidden: true)
2. Visible agents that simply don't match the --filter pattern

The footer then prints this inflated count as "N hidden", misleading users into thinking N agents exist but are hidden, when in reality most of them are visible agents that just don't match the search pattern.

CLI Output Demonstrating the Bug

With 6 agents total (4 visible, 2 hidden), running cortex agent list --filter foo:

$ cortex agent list --filter foo

Name                 Mode       Source     Description
----------------------------------------------------------------------------------
foo-analyzer         primary    local      Analyzes foo files
foo-reviewer         subagent   local      Reviews foo code

Showing 2 agents (2 primary, 1 subagents, 4 hidden - use --all to show all)
                                            ^^^^^^^^
                                            WRONG: only 1 hidden agent matches "foo"
                                            The other 3 are visible agents that don't
                                            match the pattern

Expected output:

Showing 2 agents (2 primary, 1 subagents, 1 hidden - use --all to show all)

Steps to Reproduce

1. Have a workspace with multiple agents, some hidden and some visible, with varying names
2. Run cortex agent list --filter <pattern> where the pattern matches fewer agents than the total
3. Observe the N hidden count in the footer is inflated — it includes visible agents that don't match the filter

Expected Behavior

hidden_count should only count truly hidden agents (those not shown because of hidden: true), not agents that are merely excluded by the --filter pattern.

Fix: Compute hidden count independently of the pattern filter:

let hidden_count = if !args.all {
    agents.iter().filter(|a| a.hidden).count()
} else {
    0
};

Actual Behavior

hidden_count = agents.len() - filtered.len() counts all non-displayed agents as "hidden", including visible ones excluded by --filter.

The burden of proof is on the submitter.\" Wait, the instructions say \"BOTH code AND screenshot must pass for plausible=true\". If there are no screenshots, does it pass? The instructions say \"You MUST call analyze_screenshot for EVERY screenshot URL in the bug report.\" Since there are none, I didn't call it. \"Screenshot shows real CLI execution with the described error -> screenshot_valid=true\". If there are no screenshots, I should probably set screenshot_valid=false, which means plausible=false. Let me re-read: \"BOTH code AND screenshot must pass for plausible=true\". Since there are no screenshots, screenshot_valid=false, and plausible=false."
