A skill is just a few plain-text files. Only the main one is required. The rest are optional, added as the work needs them. This is what the skill is made of; how it runs is just below.

how it's graded - what counts as a good run 4 criteria · 2 deterministic · 2 judge

Each row is one thing a good run has to get right. deterministic means a quick check decides, pass or fail. judge means the AI reads the result and rates it. Grading each piece on its own (instead of one overall score) shows exactly where a run fell short, so the fix is obvious.

name
kind
check
calls_send_imessage
deterministic
The skill execution log must contain a call to the sendIMessage() function. (e.g., check 'state/log/pending-eval.ndjson' for relevant entries indicating function calls).
calls_read_recent
deterministic
The skill execution log must contain a call to the readRecent() function. (e.g., check 'state/log/pending-eval.ndjson' for relevant entries indicating function calls).
output_matches_imessage_api
judge
The output of the skill, particularly from readRecent(), should reflect a structure consistent with the iMessage API as defined in 'state/lib/imessage.ts', exhibiting correct message formats and recipient/sender information.
side_effects_honest
judge
Any iMessage sent via sendIMessage() should be verifiable on the target device, and readRecent() should accurately reflect recent messages without unexpected side effects.

how it runs - the shared frame every skill uses 5/5 present

Every skill runs the same way. One part does the work, a separate part checks it, and a short loader hands the AI exactly what it needs for the job. Anything this skill doesn't use shows a one-line note saying why, on purpose, not by accident.

Critical rules the things this skill must not get wrong
  1. iMessage send routes through Mac Mini over SSH — there's no first-party iMessage HTTP API. The Mini is the only sending host.
  2. sendIMessage is irreversible side-effect — keep behind scope-only default per program.md

what it has learned - fixes written back in over time sample

When a run hits something this skill didn't handle, the fix gets written back into the skill so it doesn't happen again. FIXED means it was corrected on the spot. LOGGED means it's queued for a bigger rewrite. Either way, the skill gets a little better and never makes the same mistake twice.

SKILL.md- the skill, written out in plain English

imessage

iMessage sending via Mac Mini SSH.

Ported from kernel snappy-imessage in Phase 0.5. See state/lib/imessage.ts for the full API surface.

Steps

  • sendIMessage() - see state/lib/imessage.ts
  • readRecent() - see state/lib/imessage.ts

Eval

Actor: the exported functions in state/lib/imessage.ts. Auditor: none wired yet - eval is manual (Robert review). File a state/log/pending-eval.ndjson row on each run.

Score convention:

OutcomeScore
Pass on first try1.0
Failed first, auto-fix applied, re-check passed0.5
Still failing or unrecoverable0.0

Gotchas

via the Phase 0.5 driver. Only these rewrites were applied: already in state/lib/)

  1. realpathSync(process.argv[1]) CLI guard wrapped in try/catch
  • See the kernel SKILL.md for the original long-form guidance if you need it

(read-only reference at the kernel path above).

Graduation

This skill is prose. Graduate by defining a deterministic auditor and flipping eval: auto.

AGENTS.md- what the AI loads when this skill comes up

imessage - loader

Per-turn rules for the imessage skill. Full reference: state/skills/imessage/SKILL.md. Do not skip these.

Critical Rules

  • iMessage send routes through Mac Mini over SSH - there's no first-party iMessage HTTP API. The Mini is the only sending host.
  • sendIMessage is irreversible side-effect - keep behind scope-only default per program.md

Commands

| ui dashboard | state/skills/imessage/resources/ui.openui | |invoke: import from state/lib/imessage.ts - sendIMessage(), readRecent() |verify: readRecent() after a send to confirm the message landed in the local store |eval log: state/log/pending-eval.ndjson (manual eval - skill: "imessage")

OpenUI Resource

  • Skill-owned OpenUI Lang resource: state/skills/imessage/resources/ui.openui. Read it before rendering or editing this skill's generated component surface.
  • Treat this resource as a first-class artifact of the skill, not a generic chat response. Improve it when the skill's user-facing output needs to become richer.
  • System resources compose OpenUI primitives and inherit SnappyChat tokens. Use ui_contract: branded in SKILL.md only for deliberate platform or client visuals.

Known Pitfalls

  • SSH path to Mac Mini must be reachable - no fallback. If the Mini is offline, sends silently fail; verify with readRecent.
  • Mac Mini server context: see mac-mini-server skill / mac-mini-remote-ops skill in the wider catalog if SSH config drifts

Self-Test

An agent reading this should correctly:

  1. [ ] Default sendIMessage to scope-only
  2. [ ] Verify sends with readRecent, not just trust the SSH return
  3. [ ] Recognize the Mac Mini SSH dependency

Self-report

If this loader fell short, append a line:

echo "[$(date -u +%FT%TZ)] imessage: <what was missing>" >> state/log/loader-feedback.log

<!-- kernel-ok: historical attribution for the PID-loader pattern. -->

Self-correcting loader (PID feedback)

This is the rule that makes loaders learn. Ported from snappy-kernel, where it demonstrably worked: the snappy-dom-cartographer skill mapped Skool admin UI once, every later ship-agent inherited the full map for free.

Before you finish, do two things:

1. Fix gaps (P - proportional). MANDATORY. If this loader didn't cover your case - if you had to read another file, run an undocumented command, work around a wrong selector, or discover a quirk - you MUST attempt an Edit to this AGENTS.md before you log.

  • Default action: edit this file. Surgical. Add the missing line, table

row, or code example where it belongs. No restructuring.

  • Only LOGGED is allowed when: the fix needs >10 lines, spans multiple

files, or requires a structural rewrite. In that case the state/regen/drain.sh queue picks it up asynchronously.

  • "I didn't have time" / "it's minor" / "the next agent will figure it out"

are NOT valid reasons. Minor gaps compound - that's the whole point of this loop.

  • Concrete example of a valid P-fix: discover agent-browser screenshot

takes path positionally not as --output <path>. One line in a table. Edit it in. Do not just log it.

  • The goal: the next agent never has to leave the loader.

2. Log the result.

echo "[$(date -u +%FT%TZ)] imessage: <what was missing or fixed> [FIXED|LOGGED]" >> state/log/loader-feedback.log
  • FIXED = you patched this loader inline (P-fix).
  • LOGGED = too large for inline; the PostToolUse enqueue + Stop-hook drain

will rewrite the loader from scratch on next session-end.

Do not skip this. Every agent run must leave the system better than it found it. The loader is the setpoint; you are the sensor; the gap is the error signal; closing the gap is the correction.
