Sidecar is a terminal-based workspace for running AI coding agents alongside file trees, task issues, Git diffs, and Jira or GitHub resources in split panes. Developers use it to monitor agent sessions, inspect files and changes, manage workspaces, and handle tasks without leaving one shell. The catalogue entries extend or guide coding-agent workflows used with Sidecar.
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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Agent Snooping · line 583 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
What it costs to keep this loaded
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 5.1 | $0.00059 | $0.11924 |
| Opus 5.5 | $0.00024 | $0.04770 |
| Sonnet 5.5 | $0.00012 | $0.02385 |
| Haiku 4.5 | $0.00006 | $0.01192 |
Grade A, and why
keyboard-shortcuts 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 1mo 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 — 843 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Keyboard Shortcuts
Complete shortcut listings and context reference for all sidecar plugins. For implementation patterns, see docs/guides/deprecated/ui-feature-guide.md. For a detailed assessment of inconsistencies, vim alignment, mnemonic quality, and improvement proposals, see references/assessment.md in this skill directory.
Architecture
- Centralized binding registry:
internal/keymap/bindings.gois the single source of truth for key bindings. - Context-based dispatch: Each plugin defines contexts; bindings are scoped to contexts.
- Command palette (
?): Auto-discovers bindings for discoverability. - User overrides: Supported via
~/.config/sidecar/config.json. - Key sequences: Compound commands like
g gare supported with 500ms timeout.
Adding a New Shortcut
- Add the binding in
internal/keymap/bindings.gounder the appropriate context. - Add command handling in the plugin's
Update()method (usually in ahandlers.gofile). - Add the command to the plugin's
Commands()method for footer hint and command palette. - Keep command names short (1 word preferred) to prevent footer wrapping.
TD Monitor Shortcuts
TD shortcuts are dynamically exported from TD itself via ExportBindings() and ExportCommands() in pkg/monitor/keymap/. TD is the single source of truth. To add TD shortcuts:
- Add binding to TD's
pkg/monitor/keymap/bindings.go - Add command constant to TD's
pkg/monitor/keymap/registry.go - Add metadata to TD's
pkg/monitor/keymap/export.go - Handle in TD's
pkg/monitor/model.go

What ships with it
1 file 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.

keyboard-shortcuts is a skill published in the GitHub repository marcus/sidecar (1,092 stars, last pushed 19d ago), licensed MIT. It adds 59 tokens to every session and 11,924 once invoked, about $0.0002 per session on Opus 5.5. 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.
