Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00143 | $0.02093 |
| Opus 5 | $0.00072 | $0.01046 |
| Sonnet 5 | $0.00029 | $0.00419 |
| Haiku 4.5 | $0.00014 | $0.00209 |
Grade A, and why
taskmate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TaskMate — Vikunja task companion
All Vikunja access goes through the bundled CLI (Python, run via uv, inline deps):
uv run "${CLAUDE_PLUGIN_ROOT}/skills/taskmate/scripts/taskmate.py" <command> ...
If ${CLAUDE_PLUGIN_ROOT} is not set in your environment, resolve the script path relative to
this SKILL.md file. Examples below abbreviate the invocation to taskmate.py <command>.
Output is compact and line-oriented; add --json when you need full API objects.
taskmate.py <command> --help documents every flag.
Self-healing configuration
Any command exits with code 2 and a structured JSON error (error: not_configured, with a
fix command and an ask_user list) when no valid config exists. When that happens:
- Interactive session: ask the user for the missing pieces (server URL; API token created
in Vikunja under User Settings → API Tokens; mode
userorcompanion), then runtaskmate.py configure --url ... --token ... --mode ....configurevalidates against the server before saving, so a typo'd URL or token fails fast. For a guided experience, suggest/taskmate:setup. - Non-interactive run (scheduled job, no human available): print
TASKMATE_NOT_CONFIGURED: <what is missing>and stop. Never guess or invent credentials. 401on a previously working setup: the token was revoked or expired — tell the user and collect a fresh token; everything else is preserved.
taskmate.py doctor diagnoses config path, profiles, auth, and reachability — run it first
whenever something smells wrong. Config lives in ~/.config/taskmate/config.json as named
profiles; VIKUNJA_URL/VIKUNJA_TOKEN env vars override, --profile NAME selects. Treat
tokens as secrets: never echo a full token, never write one into a repo file; when referring
to one, mask it (tk_f2...1eef).
Modes: whose hands are you?
The active profile's mode decides your identity on the board. Read
references/etiquette.md before board-facing writes in companion
mode, and whenever you shape tone or personality.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

taskmate is a skill published in the GitHub repository titusz/skills (2 stars, last pushed 11d ago), licensed MIT. It adds 143 tokens to every session and 2,093 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
