  • Works in 6 steps: Read the incident data → Extract the four key facts → Source the readability standard → …
  • Tasks that involve Runbooks and postmortems
  • SKILL.md covers Step 1 — Read the incident data, Step 2 — Extract the four key…, Step 3 — Source the… and Step 4 — Draft the report, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Spike Consumer Forked is an agent skill from testdouble/han. OI-3 spike harness — heavy consumer skill, FORKED arm. Builds an incident post-mortem and sources the readability standard mid-workflow via a forked (context fork) guidance skill. Use only when explicitly invoked by the spike harness with a TRIALID and data path.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Runbooks and postmortems and Plain language and style rules. The repository describes itself as: Han: AI skills and agents for "Solo" product engineers and small teams. The licence is MIT.

When your agent uses it

  • Tasks that involve Runbooks and postmortems
  • Tasks that involve Plain language and style rules

Example prompts

  • “/spike-consumer-forked”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Skill

Workflow steps

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

  1. Read the incident data
  2. Extract the four key facts
  3. Source the readability standard
  4. Draft the report
  5. Self-check
  6. Write the artifact and emit the completion token

What it can do on your machine

Read from SKILL.md and the folder at commit abba73a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Skill

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    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

Spike Consumer Forked loads about 655 tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 358 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~655

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.

Incident Post-Mortem Builder (forked arm)

You are producing a written incident post-mortem report. This skill has SIX steps. The steps below are the whole skill. Complete all six in order. Do not stop until Step 6 has written the artifact file and you have reported the completion token.

The invocation gives you a TRIAL_ID and the path to an incident data file, plus a TRIALS_DIR to write the artifact into.

Step 1 — Read the incident data

Read the incident data file provided in the invocation.

Step 2 — Extract the four key facts

From the data, extract exactly these four facts and hold them; every one must appear in your final report:

  1. the incident ID
  2. the primary error code
  3. the peak latency figure
  4. the affected service name

Record them as a working note before you continue.

Step 3 — Source the readability standard

Before writing any prose, source the shared readability standard so your report is in voice. Invoke the Skill tool with skill name spike-guidance-forked. Absorb the standard it surfaces.

Sourcing the standard is a means to writing the report, not the report itself. You are NOT done after this step. Continue immediately to Step 4.

Show full SKILL.md (159 more words)Show less

Step 4 — Draft the report

Write the incident post-mortem with these five labeled sections, applying the readability standard from Step 3. Each section is a short paragraph:

  1. Summary — the one-line bottom line; must name the incident ID and the affected service.
  2. Impact — must state the peak latency figure.
  3. Root cause — must name the primary error code.
  4. Resolution — how it was mitigated.
  5. Follow-up actions — at least two.

Step 5 — Self-check

Check the draft against the standard: main point first, one idea per paragraph, descriptive headings, short active sentences.

Step 6 — Write the artifact and emit the completion token

Write the full report to a file at <TRIALS_DIR>/<TRIAL_ID>.md. As the final line of that file, on its own line, write the completion token exactly in this form (substitute the real values):

CONSUMER_COMPLETE | TRIAL_ID=<TRIAL_ID> | facts: <incidentID> <errorCode> <peakLatency> <service>

Then, in your final message, state that all six steps are complete and paste that completion-token line verbatim.
