What it does

Tendril Debug Plan is an agent skill from Ivy-Interactive/Ivy-Tendril. Debug a Tendril plan by analyzing its execution logs, session JSONL, verification results, and checking infrastructure. Produces actionable bugfix and improvement recommendations. Use when the user wants to investigate why a plan failed, behaved unexpectedly, or to audit plan execution quality.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/common-failure-modes.md`, `references/jsonl-analysis.md` and `references/verification-pipeline.md`).

It sits in Development. The repository describes itself as: AI agents can now write 99% of the code. This changes what it means to be a developer. Our role shifts to knowing "what good looks like". To do that, we need completely new…

When your agent uses it

  • The user wants to investigate why a plan failed
  • Behaved unexpectedly
  • Audit plan execution quality

Example prompts

  • “/tendril-debug-plan”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Gather Plan Artifacts
  2. Locate and Analyze Session JSONL
  3. Analyze the Checking/Verification Pipeline
  4. Produce Recommendations Report

What it can do on your machine

Read from SKILL.md and the folder at commit 3a1a241. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tendril Debug Plan loads about 2.8k tokens when it runs, and up to ~6.5k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 918 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 918 words (~2,838 tokens).

“Debug and analyze Tendril plan executions end-to-end - from plan creation through checking/verification - and produce a set of concrete bugfix and improvement recommendations.”
