## What it does

The skill investigates Tendril runs using a five-digit job identifier like `00458` or a direct path to a log file. It inspects artifacts stored in `$TENDRIL_HOME/Jobs/`, including the `{stem}.md` run log and unparsed stream output in `{stem}.raw.jsonl`.

Execution follows five inspection phases. First, it extracts exit codes, durations, token costs, and mid-run agent notes. Next, it parses stream JSON lines to trace tool failures and redundant file edits. Then it validates agent decisions against `Program.md` rules and relevant Tendril C# components.

All recommendations print directly into the chat without saving new files to disk. Without run artifacts present in `$TENDRIL_HOME/Jobs/`, the skill cannot diagnose anything.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Ivy-Interactive/Ivy-Tendril --skill tendril-debug-job -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tendril-debug-job/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tendril-debug-job/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Ivy-Interactive/Ivy-Tendril --skill tendril-debug-job -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tendril-debug-job/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Ivy-Interactive/Ivy-Tendril --skill tendril-debug-job -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tendril-debug-job/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Ivy-Interactive/Ivy-Tendril tendril-debug-job
```

2. **Manually: put the files in place**
- File: `.github/skills/tendril-debug-job/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Ivy-Interactive/Ivy-Tendril --skill tendril-debug-job -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Ivy-Interactive/Ivy-Tendril --path skills/tendril-debug-job
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tendril-debug-job/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Ivy-Interactive/Ivy-Tendril --skill tendril-debug-job -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Ivy-Interactive/Ivy-Tendril/tree/HEAD/skills/tendril-debug-job/SKILL.md

## When to use it
- diagnose failed Tendril runs by job identifier
- detect repetitive file edits and compilation error loops
- verify agent adherence to `Program.md` promptware instructions
- audit token waste and cache efficiency across raw JSONL logs

## Example prompts
- /tendril-debug-job 00458 agent got stuck in an edit loop on a single file
- /tendril-debug-job 00124 inspect token overspending and investigate build failure

# tendril-debug-job

Analyze a job's execution artifacts to identify issues and improvement opportunities in Tendril, the promptware instructions, memory, or tools.

## Invocation

```
/tendril-debug-job <job-id> <comment>
```

* **job-id** - Five-digit job id (e.g., `00458`). A full path to a job log also works.
* **comment** - Free-text describing what to look for or what went wrong

## Job Artifacts

Every job writes four files, flat, into `$TENDRIL_HOME/Jobs/`. They share one stem:

```
{jobId}-{planId}-{promptware}      e.g. 00458-00044-ExecutePlan
{jobId}-{promptware}               when the job has no plan (e.g. CreatePlan)
```

| File | Name |
|------|------|
| `{stem}.md` | **Job Log** - status, timings, CLI command, final output, agent-authored `## Agent Log` sections |
| `{stem}.prompt.md` | **Job Prompt** - the exact prompt handed to the agent |
| `{stem}.raw.jsonl` | **Job Raw Log** - unparsed CLI stream-json output |
| `{stem}.eventwire.jsonl` | **Job Eventwire Log** - Tendril's parsed event stream |

Locate them with a glob on the job id:

```bash
ls "$TENDRIL_HOME/Jobs/00458-"*
```

The promptware type is the **last** dash-separated segment of the stem; the plan id, when present, is the middle segment. There is no `Logs/` folder anywhere - not under promptwares, not under plans.

## What This Skill Does

1. Reads the Job Log, the Job Prompt, and the Job Raw Log
2. Reconstructs the agent's execution timeline: tool calls, decisions, errors, retries
3. Cross-references with the promptware's Program.md, Memory, and Tools
4. Identifies concrete improvements to Tendril code, promptware instructions, or agent behavior
5. Produces actionable recommendations

## Execution Steps

### Phase 1 - Read the Job Log and Job Prompt

The Job Log (`{stem}.md`, produced by `JobLogWriter`) has this structure:

```markdown
# Job Log {stem}

- **JobId:** {id}
- **PlanId:** {planId}   # present whenever the job produced or targeted a plan
- **Status:** {Completed|Failed|Timeout}
- **Exit Code:** {0|1|N/A}
- **Started:** {timestamp}
- **Completed:** {timestamp}
- **Duration:** {seconds}s
- **Provider:** {claude|copilot|codex|...}
- **SessionId:** {id}
- **Cost:** ${amount}
- **Tokens:** {count}

## CLI Command
{full command line}

## Final Output
{agent's last text response}

## Outcome
{commits, verifications, final plan state - ExecutePlan/RetryPlan only}

## Agent Log - {action} ({timestamp})
{narrative the agent appended mid-run via `tendril job add-log`}
```

The compiled prompt is **not** in this file. Read `{stem}.prompt.md` for the full firmware + Program.md + references + custom instructions.

Extract:
- The promptware type and plan id (from the stem)
