continuous-test-generation

An automated loop that finds untested code paths, creates tests for them, and reviews those tests. It uses TDD-style work, where tests help check that code behaves as expected.

In plain words
What is it for?
Use it to identify test gaps, generate tests, and review the generated tests repeatedly until only minor gaps remain.
Why use it?
It reduces the manual effort of finding missing tests and checking whether newly generated tests are correct.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

continuous-test-generation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/continuous_test_generation.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

continuous-test-generation

Purpose

Run the continuous-test-generation workflow in continuous mode until the dispatcher returns recommended_role: stop (only [MINOR] test gaps remain).

The workflow rotates through three prompt steps in a strict cycle:

  1. prompt.test_gap_analysis — identify untested code paths (runs every 3rd checkpoint)
  2. prompt.test_generation — generate tests for identified gaps
  3. prompt.test_review — review generated tests for correctness

Cold starts are handled automatically — the infrastructure initialises the rotation at step 1 when no prior runtime entry exists.

Agent execution protocol

Run one dispatcher step at a time:

# 1. Ask the dispatcher for the next prompt
python3 .codex/skills/vibe-loop/scripts/agentctl.py --repo-root . --format json next --workflow continuous-test-generation

# 2. Read the prompt body from the catalog path returned by the dispatcher
python3 .codex/skills/vibe-prompts/scripts/prompt_catalog.py <prompt_catalog_path> get <recommended_prompt_id>

# 3. Execute the prompt body (do the actual test generation work)

# 4. After execution, record the loop result
python3 .codex/skills/vibe-loop/scripts/agentctl.py --repo-root . --format json loop-result --line "LOOP_RESULT: <json>"

# 5. Repeat from step 1 until recommended_role == "stop"

The --workflow continuous-test-generation flag is required — it activates the continuous override that ignores normal plan-state routing and selects from the test generation prompt rotation instead.

In this orchestration source repo, use tools/agentctl.py and tools/prompt_catalog.py instead; the .codex runtime helper scripts are generated during install.

LOOP_RESULT format

After executing each prompt, emit a LOOP_RESULT JSON line with the dispatcher-required report fields:

{
  "loop": "implement",
  "result": "ready_for_review",
  "stage": "<current_stage>",
  "checkpoint": "<current_checkpoint>",
  "status": "<current_status>",
  "next_role_hint": "implement|review|stop",
  "workflow": "continuous-test-generation",

        "critical": true,
        "confidence": 0.9,
        "evidence_strength": "LOW|MEDIUM|HIGH"
      }
    ],
    "top_findings": [
      {"impact": "MAJOR|MINOR", "title": "[MAJOR|MODERATE|MINOR] ...", "evidence": "...", "action": "..."}
    ],

    },

      "loop": "implement",

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

continuous-test-generation is a skill published in the GitHub repository brifl/coding-agent-orchestration (20 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 1,076 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
