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 | $0.00051 | $0.00633 |
| Opus 5 | $0.00026 | $0.00316 |
| Sonnet 5 | $0.00010 | $0.00127 |
| Haiku 4.5 | $0.00005 | $0.00063 |
Grade A, and why
implement-task 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 yesterday.
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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Work on a task. Provide a task key, or omit to pick from the lists below.
$ARGUMENTS
If a task key was given above, read it with binder read <key> --format yaml. If the key doesn't exist, tell the user and stop. Otherwise, pick from the lists below and then read it.
Check the task's status:
- draft — needs refinement first, not ready to work on. Tell the user.
- complete or cancelled — nothing to do. Tell the user.
- pending, active, paused — proceed.
Active Tasks
!binder search type=Task status=active -f "key,title,taskType,size,priority,module" --format tsv
Pending Tasks
!binder search type=Task status=pending -f "key,title,taskType,size,priority,module" -o "!priority" --format tsv
Choosing a guide
After reading the task, decide which guide to load based on what it needs right now.
| Condition | Guide |
|---|---|
fix task, rootCause empty |
guides/investigate.md — find root cause |
requires or relatesTo links to a Problem record (check linked keys) |
guides/discuss.md — resolve open questions |
specification empty, and task is medium+, refactor, or agent |
guides/design.md — produce a specification |
| fix/feat/refactor/test task that still needs tests | guides/write-tests.md — write tests |
| None of the above apply | guides/implement.md — implement |
Multiple conditions can match. Start with the topmost one that applies, or follow the user's direction. Read the guide, then follow its instructions.
After completing a guide, re-read the task and check the table again. If another condition applies, load that guide next. If no conditions match, go to implement.
Updating multi-line fields
For single-value fields: binder update <key> field=value
For multi-line or rich text fields (rootCause, specification, details, etc.), use a transaction file:
- author: agent
records:
- $ref: <key>
specification: |

What ships with it
7 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.

implement-task is a skill published in the GitHub repository mpazik/Binder (40 stars, last pushed 9d ago), licensed MIT. It adds 51 tokens to every session and 633 once invoked, about $0.0003 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 2026-08-30.
