Qstack

/qstack

Show what is installed, then what to run next. Nothing is stored in this file: every run reads the skills on disk at that moment, so a skill added or a collection installed yesterday appears today.

1. Read the installed skills

Run this once. It prints one row per skill as collection<TAB>name<TAB>description.

import json, os, re
home = os.path.expanduser("~")
lock = os.path.join(home, ".agents", ".skill-lock.json")
sources = {}
if os.path.isfile(lock):
    for name, entry in json.load(open(lock)).get("skills", {}).items():
        sources[name] = entry.get("source", "")
COLLECTIONS = {"mattpocock/skills": "Matt Pocock"}
def description(path):
    lines = open(path, encoding="utf-8").read().splitlines()
    if not lines or lines[0] != "---":
        return ""
    out, folded = [], False
    for line in lines[1:]:

            break
        if folded:
            if line[:1].isspace():
                out.append(line.strip())
                continue
            break
        m = re.match(r"^description:\s*(.*)$", line)
        if m:
            value = m.group(1).strip()
            if value in ("", ">", "|", ">-", "|-"):
                folded = True
            else:
                return value.strip('"')
    return " ".join(out)

for d in (".claude/skills", ".codex/skills", ".agents/skills"):
    root = os.path.join(home, d)
    if not os.path.isdir(root):
        continue
    for name in sorted(os.listdir(root)):
        md = os.path.join(root, name, "SKILL.md")

        else:
            continue
        seen.add(name)
        rows.append((group, name, description(md)))
order = {"qstack": 0, "human-review": 1}
for group, name, desc in sorted(rows, key=lambda r: (order.get(r[0], 2), r[0], r[1])):
    print(f"{group}\t{name}\t{desc}")

What the command decides, so you do not have to:

• A skill belongs to QStack when its directory is qstack or starts with qstack-. That is the naming contract install and skills.sh both keep.
• human-review is its own collection.
• Any other skill is included only when ~/.agents/.skill-lock.json records it as installed from mattpocock/skills. That lock file is written by the skills.sh CLI, which is how QStack's installer adds that collection.
• Skills from collections QStack does not install (gstack, greptile, ...) are left out. They have their own routers.
• A skill linked into more than one harness directory is listed once.

If the command prints nothing, say that no QStack skills were found under ~/.claude/skills, ~/.codex/skills, or ~/.agents/skills, and stop.

2. Render the tables

Condense each description to one line:

• Keep the first sentence. Drop any "Use when ...", "Use for ...", or "Triggers on ..." clause; that text is for the model, not the reader.
• About twelve words at most, starting with a verb, no trailing full stop.
• Say only what the description says. Do not add detail it lacks.
• Keep the order the command printed.

Output exactly this, and nothing before it:

## qstack

| Skill | What it does |
| --- | --- |
| /qstack-plan-prior-art | ... |

## Installed with qstack

| Skill | Collection | What it does |
| --- | --- | --- |
| /human-review | human-review | ... |
| /ask-matt | Matt Pocock | ... |

Write each skill as /name. Omit the second table when the command printed no rows outside qstack. No preamble, no install advice, no remarks about skills that are absent.

3. Recommend the next skill

Apply the /qstack-next skill. In a host without a skill tool, read its SKILL.md from the same skills directory and follow it. Append its output under a ## Next heading. When it has nothing to recommend, omit the heading.
