At a glance

What it does

05 Spike is an agent skill from ai-driven-dev/framework. Produces an evidence-bounded spike for an uncertainty blocking estimation, feasibility, or design. Use when the user wants to frame, investigate, resume, or conclude one. Not for general research or implementation.

Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including reference files and assets (for example `actions/01-create.md`, `actions/02-investigate.md` and `actions/03-conclude.md`).

The repository describes itself as: Marketplace Framework AI-Driven Dev : Context Engineering, Plugins, Agents, Skills, Hooks, Templates, SDLC. The licence is MIT.

When your agent uses it

  • The user wants to frame

Example prompts

  • “Use the 05-spike skill to produce an evidence-bounded spike for an uncertainty blocking estimation, feasibility, or design”
  • “/05-spike”

What it can do on your machine

Read from SKILL.md and the folder at commit 6e30640. 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 mermaid).

    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

05 Spike loads about 329 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 77 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~329
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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.

Transversal rules

  • Keep product and lifecycle decisions with the user.
  • Separate evidence, decisions, and assumptions.
  • Preserve source links and existing edits.
  • Ask natural questions; never expose actions, references, or unchanged state.
  • Require explicit approval or caller-provided bounded authority before any write.
  • Bound the question; never answer beyond its stop condition.
